Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Major video changes of the day (October 3rd, 2024) 8514/A changes: 1. Correct interlaced display resolution. 2. Added a limit to cursor coordinates. 3. Test/WIP features of the add-on Mach8 side (ATI 8514/A Ultra) such as configurable BIOS. 4. Made the CMD 5 of the acceleration (Polygon Boundary) more accurate per manual (as much as I could regarding the clipping). Cirrus related: 1. Added SUBSYS PCI vendor/device ID of the 5480 (per manual). IBM VGA: 1. Built-in/option rom-less VGA don't need the "available" flag. ATI Mach8/32: 1. As with 8514/A, corrected interlaced display. XGA-1/-2: 1. Moved the XGA R/W memory size tests out of the SVGA R/W routines to reflect the per card basis, although anything that uses its own SVGA mapping would call the tests there (such as Cirrus, Headland and ATI) when not accessing the LFB. This finally puts an end to the XGA MCA mapping enabling bugs. 2. Re-organized the ISA standalone and non-standalone (INMOS) sides of the chips so that they work properly and remove the FILE rom loading hack from init. 3. The Memory Mapped R/W sides now account for instance in their address range. 4. INMOS only: prevent any ROM address access to anything lower than 0xc8000 to not conflict with the main BIOS rom loading. 5. Fixed native pitch by using the correct register, this fixes non 1024x768 resolutions under NT. 6. More logs when enabled to see any future bugs.

Video changes of the day (November 13th, 2024) 1. Finally add the ATI 8514/A Ultra add-on BIOS in both ISA and MCA variants (despite the ROM page failure on POST). 2. Fixed a mode switch bug in the Mach8 (both add-on and vga combo) when exiting the Win3.x GUI using the native drivers. 3. Corrected (best possible) the eeprom load of the Mach8 products. 4. Partial implementation of the FIFO on the 8514/A compatible products including Mach8/32 and plain IBM 8514/A.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Mach32 changes of the day (February 20th, 2025) 1. Actually fix the LFB access by subtracting the linear base address from the current address when LFB/MMIO is on. This fixes blankness of certain Mach32 drivers on Win3.1x. 2. Apply a minor but important fix to the fonts used by said Win3.1x driver when the dpconfig activates bit 2 without bit 12 set (e.g.: 0x2255), ergo, issuing host data as monochrome without swapping it.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)
2023-07-14 23:38:04 +02:00
Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Mach32 changes of the day (February 20th, 2025) 1. Actually fix the LFB access by subtracting the linear base address from the current address when LFB/MMIO is on. This fixes blankness of certain Mach32 drivers on Win3.1x. 2. Apply a minor but important fix to the fonts used by said Win3.1x driver when the dpconfig activates bit 2 without bit 12 set (e.g.: 0x2255), ergo, issuing host data as monochrome without swapping it.

If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips).

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Video changes: 1.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7.

Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5.

Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Mach32 changes of the day (February 20th, 2025) 1. Actually fix the LFB access by subtracting the linear base address from the current address when LFB/MMIO is on. This fixes blankness of certain Mach32 drivers on Win3.1x. 2. Apply a minor but important fix to the fonts used by said Win3.1x driver when the dpconfig activates bit 2 without bit 12 set (e.g.: 0x2255), ergo, issuing host data as monochrome without swapping it.

Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Re-organized ATI Mach8/32 LFB access as well as 8514/A/ATI mode toggles, should end the video mode issues once and for all. 3.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Cirrus, ATI Mach8/32 and XGA fixes. 1. Update svga->fast to account for packed chain mode toggles, fixes issues on Descent II for DOS using the Cirrus cards. 2. Re-organized ATI Mach8/32 LFB access as well as 8514/A/ATI mode toggles, should end the video mode issues once and for all. 3. Fixed a small but major pattern issue with IBM OS/2 1.30.1's XGA driver (not .2, which is fine as is).

Fixing regressions of the mach32 (November 5th, 2024) 1. ATI Extended 8514/A mode may not use bit 5 of ATI reg 0xb0 sometimes but at the same time it won't use the standard VGA way of setting up 256+ colors, therefore, in the VGA DAC writes, use standard VGA way to revert to VGA mode in the writes instead of relying on bit 5 of ATI reg 0xb0 being enabled/disabled there. Fixes mode switches in VLB/PCI configurations using Windows 9x and possibly other stuff, ISA is unaffected and still works fine. 2. Added more logs and and remove/set I/O handlers correctly for the PCI side.

Even better (hopefully) way to fix the mode switches (November 3rd, 2024) 1. Added the missing call to mach32_updatemapping from port 0x3CF through its index 6. 2. If the accelerator DAC is active and the extended 256 color bit is on too then enable 8514/A mode when needed, otherwise it's VGA mode or decided by the passthrough/clock selection ports. 3. VGA DAC reads are redirected to the 8514/A DAC reads only when 8514/A mode is on.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2.

Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Even better (hopefully) way to fix the mode switches (November 3rd, 2024) 1. Added the missing call to mach32_updatemapping from port 0x3CF through its index 6. 2. If the accelerator DAC is active and the extended 256 color bit is on too then enable 8514/A mode when needed, otherwise it's VGA mode or decided by the passthrough/clock selection ports. 3. VGA DAC reads are redirected to the 8514/A DAC reads only when 8514/A mode is on.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Video changes of the day (January 26th, 2025) XGA: 1. Added a proper poll so to have its timings independent of the SVGA core and changes its renderer accordingly, mainly a blank render one. 2. Workaround the Ctrl-Alt-Del reset of Windows 2.x so that it switches back to VGA text mode correctly when using the 0xA000 64K aperture (in vid_svga.c). SVGA core: Re-organized the way the different timers are organized so that the XGA and 8514/A pollers can coexist with the SVGA timer without conflicts. ATI Mach32: Reworked the true color renderer and made it a Mach32 exclusive due to its differences from the standard one. Fixes wrong rendered colors in NT using the 32bpp renderer in RGB mode.

The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

XGA-1/-2: 1. Moved the XGA R/W memory size tests out of the SVGA R/W routines to reflect the per card basis, although anything that uses its own SVGA mapping would call the tests there (such as Cirrus, Headland and ATI) when not accessing the LFB. This finally puts an end to the XGA MCA mapping enabling bugs. 2. Re-organized the ISA standalone and non-standalone (INMOS) sides of the chips so that they work properly and remove the FILE rom loading hack from init. 3. The Memory Mapped R/W sides now account for instance in their address range. 4. INMOS only: prevent any ROM address access to anything lower than 0xc8000 to not conflict with the main BIOS rom loading. 5. Fixed native pitch by using the correct register, this fixes non 1024x768 resolutions under NT. 6. More logs when enabled to see any future bugs.

Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Small but important video changes of the day (October 27th, 2024) 8514/A compatibles: 1. The mode switch (from VGA to 8514/A/ATI and vice-versa) has been fixed again (for the Nth time). 2. Removed a pattern hack used on DPCONFIG = 0x5211 on bitblt, now patterns work properly using the ATI Mach8 3.0 win3.1x drivers. 3. Clipping regs are more accurate for acceleration. XGA 1-2: A picky OS is a picky OS, fixes to the Win95 fonts (which uses the pattern sources) applied.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Mach8/32 fixes (again): 1. Fixed wrong setting of highres and lowres mode of 8bpp, makes Transport Tycoon run properly on these ATI cards again. 2. 32-bit (RGBA) True Color is actually supported on the Mach32, but barely used, and the original code was wrong. This fix makes 32-bit True Color render the right colors.

New batch of ATI Mach8/32 changes: 1. Hopefully fixed the passthrough stuff for good and fixed typo's in the IBM 8514/A poll function about the cursor. 2. Eliminated the ibm8514_on global variable in favor of a struct variable to be consistent with XGA.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

More ATI accel fixes and undocumented stuff. 1. Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers. 2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Video changes of the day (November 13th, 2024) 1. Finally add the ATI 8514/A Ultra add-on BIOS in both ISA and MCA variants (despite the ROM page failure on POST). 2. Fixed a mode switch bug in the Mach8 (both add-on and vga combo) when exiting the Win3.x GUI using the native drivers. 3. Corrected (best possible) the eeprom load of the Mach8 products. 4. Partial implementation of the FIFO on the 8514/A compatible products including Mach8/32 and plain IBM 8514/A.

Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8.

Video changes of the day (November 13th, 2024) 1. Finally add the ATI 8514/A Ultra add-on BIOS in both ISA and MCA variants (despite the ROM page failure on POST). 2. Fixed a mode switch bug in the Mach8 (both add-on and vga combo) when exiting the Win3.x GUI using the native drivers. 3. Corrected (best possible) the eeprom load of the Mach8 products. 4. Partial implementation of the FIFO on the 8514/A compatible products including Mach8/32 and plain IBM 8514/A.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Huge fixes to 8514/A compatibles: 1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes of the day (November 13th, 2024) 1. Finally add the ATI 8514/A Ultra add-on BIOS in both ISA and MCA variants (despite the ROM page failure on POST). 2. Fixed a mode switch bug in the Mach8 (both add-on and vga combo) when exiting the Win3.x GUI using the native drivers. 3. Corrected (best possible) the eeprom load of the Mach8 products. 4. Partial implementation of the FIFO on the 8514/A compatible products including Mach8/32 and plain IBM 8514/A.

More ATI accel fixes and undocumented stuff. 1. Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers. 2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Video changes of the day (November 13th, 2024) 1. Finally add the ATI 8514/A Ultra add-on BIOS in both ISA and MCA variants (despite the ROM page failure on POST). 2. Fixed a mode switch bug in the Mach8 (both add-on and vga combo) when exiting the Win3.x GUI using the native drivers. 3. Corrected (best possible) the eeprom load of the Mach8 products. 4. Partial implementation of the FIFO on the 8514/A compatible products including Mach8/32 and plain IBM 8514/A.

Small but important video changes of the day (October 27th, 2024) 8514/A compatibles: 1. The mode switch (from VGA to 8514/A/ATI and vice-versa) has been fixed again (for the Nth time). 2. Removed a pattern hack used on DPCONFIG = 0x5211 on bitblt, now patterns work properly using the ATI Mach8 3.0 win3.1x drivers. 3. Clipping regs are more accurate for acceleration. XGA 1-2: A picky OS is a picky OS, fixes to the Win95 fonts (which uses the pattern sources) applied.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.).

Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

For some reason, background colors were always black under those drivers in 8bpp mode, added a tweak to fix it (as well as Clock colors). 2. Likewise for the red scrolling in pbrush or write, added a tweak to its bitblt read mask. 3. Don't call svga_recalctimings in the hdisp/vdisp ports directly, fixes screen size on said drivers without affecting other stuff.

Small but important video changes of the day (October 27th, 2024) 8514/A compatibles: 1. The mode switch (from VGA to 8514/A/ATI and vice-versa) has been fixed again (for the Nth time). 2. Removed a pattern hack used on DPCONFIG = 0x5211 on bitblt, now patterns work properly using the ATI Mach8 3.0 win3.1x drivers. 3. Clipping regs are more accurate for acceleration. XGA 1-2: A picky OS is a picky OS, fixes to the Win95 fonts (which uses the pattern sources) applied.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Even better (hopefully) way to fix the mode switches (November 3rd, 2024) 1. Added the missing call to mach32_updatemapping from port 0x3CF through its index 6. 2. If the accelerator DAC is active and the extended 256 color bit is on too then enable 8514/A mode when needed, otherwise it's VGA mode or decided by the passthrough/clock selection ports. 3. VGA DAC reads are redirected to the 8514/A DAC reads only when 8514/A mode is on.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Mach8/32 fixes (again): 1. Fixed wrong setting of highres and lowres mode of 8bpp, makes Transport Tycoon run properly on these ATI cards again. 2. 32-bit (RGBA) True Color is actually supported on the Mach32, but barely used, and the original code was wrong. This fix makes 32-bit True Color render the right colors.

Mach32 and clock changes of the day (September 22nd, 2024) 1. Going from screenshots of the Mach32 chips, they all have the ati18811-1 clock regardless of the bus type, whilst the Mach8 has an ati18812, which is actually a ati18811-0 2. Unbreak the NS3.1 Mach32 driver, ergo, don't block the LFB processing.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Fixing regressions of the mach32 (November 5th, 2024) 1. ATI Extended 8514/A mode may not use bit 5 of ATI reg 0xb0 sometimes but at the same time it won't use the standard VGA way of setting up 256+ colors, therefore, in the VGA DAC writes, use standard VGA way to revert to VGA mode in the writes instead of relying on bit 5 of ATI reg 0xb0 being enabled/disabled there. Fixes mode switches in VLB/PCI configurations using Windows 9x and possibly other stuff, ISA is unaffected and still works fine. 2. Added more logs and and remove/set I/O handlers correctly for the PCI side.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Even better (hopefully) way to fix the mode switches (November 3rd, 2024) 1. Added the missing call to mach32_updatemapping from port 0x3CF through its index 6. 2. If the accelerator DAC is active and the extended 256 color bit is on too then enable 8514/A mode when needed, otherwise it's VGA mode or decided by the passthrough/clock selection ports. 3. VGA DAC reads are redirected to the 8514/A DAC reads only when 8514/A mode is on.

Video, Storage and MCA changes/fixes. 1. Cirrus Logic GD54xx, Paradise/WD VGA now reset the interlace once a text mode is issued if not done automatically. 2. Paradise/WD's 15/16bpp modes using the 800x600 resolution now have the correct ma_latch, should fix most operating systems drivers using this combo. 3. More fixes (hopefully) to the accelerated pitch and rowoffset of the Trident TGUI cards (9440AGi and 96x0XGi), should fix issues with delayed displays mode changes under various operating systems (e.g.: Win3.1x). 4. Preliminary implementation of the Area Fill command of XGA, which is issued while using various painting and/or calc utilities on Win3.1x (IBM XGA updated drivers, e.g.: 2.12). 5. Preliminary (and incomplete) 4bpp XGA mode. 6. The XGA memory test for the 0xa5 using writes (used by various operating systems) no longer conflicts with DOS' XGAKIT's memory detection. 7. Small ROP fixes to both XGA and 8514/A. 8. Re-organized the mapping of the Mach32 chipset, especially when to enable the ATI mode or switching back to IBM mode, should fix LFB conflicts with various operating systems. 9. According to The OS/2 Museum, the Adaptec AHA-154xB series of SCSI cards fail the ASPI4DOS.SYS 3.36 signature check, so now make the changes accordingly. 10. Remove useless and crashy bios-less option of the Trantor T128. 11. The Image Manager 1024 card can also be used on a XT (although only if it has a V20/V30). 12. Re-organized the IBM PS/2 model 60 initialization as well as its right POS machine ID (though an update to sc.exe is still required for the POST memory amount to work normally).

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers. 2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7.

Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips).

Misc: Added the BT481 RAMDAC for future card use.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video changes: 1.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

More ATI accel fixes and undocumented stuff. 1. Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers. 2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7.

Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4.

Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Video changes of the day (November 13th, 2024) 1. Finally add the ATI 8514/A Ultra add-on BIOS in both ISA and MCA variants (despite the ROM page failure on POST). 2.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6.

The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command. 3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

More ATI accel fixes and undocumented stuff. 1. Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers. 2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.).

Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Cirrus, ATI Mach8/32 and XGA fixes. 1. Update svga->fast to account for packed chain mode toggles, fixes issues on Descent II for DOS using the Cirrus cards. 2. Re-organized ATI Mach8/32 LFB access as well as 8514/A/ATI mode toggles, should end the video mode issues once and for all. 3. Fixed a small but major pattern issue with IBM OS/2 1.30.1's XGA driver (not .2, which is fine as is).

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should.

XGA 1-2: A picky OS is a picky OS, fixes to the Win95 fonts (which uses the pattern sources) applied.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Preliminary implementation of the Area Fill command of XGA, which is issued while using various painting and/or calc utilities on Win3.1x (IBM XGA updated drivers, e.g.: 2.12). 5. Preliminary (and incomplete) 4bpp XGA mode. 6. The XGA memory test for the 0xa5 using writes (used by various operating systems) no longer conflicts with DOS' XGAKIT's memory detection. 7. Small ROP fixes to both XGA and 8514/A. 8. Re-organized the mapping of the Mach32 chipset, especially when to enable the ATI mode or switching back to IBM mode, should fix LFB conflicts with various operating systems. 9. According to The OS/2 Museum, the Adaptec AHA-154xB series of SCSI cards fail the ASPI4DOS.SYS 3.36 signature check, so now make the changes accordingly. 10. Remove useless and crashy bios-less option of the Trantor T128. 11. The Image Manager 1024 card can also be used on a XT (although only if it has a V20/V30). 12. Re-organized the IBM PS/2 model 60 initialization as well as its right POS machine ID (though an update to sc.exe is still required for the POST memory amount to work normally).

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Paradise/WD's 15/16bpp modes using the 800x600 resolution now have the correct ma_latch, should fix most operating systems drivers using this combo. 3.

Preliminary implementation of the Area Fill command of XGA, which is issued while using various painting and/or calc utilities on Win3.1x (IBM XGA updated drivers, e.g.: 2.12). 5. Preliminary (and incomplete) 4bpp XGA mode. 6. The XGA memory test for the 0xa5 using writes (used by various operating systems) no longer conflicts with DOS' XGAKIT's memory detection. 7.

Re-organized the mapping of the Mach32 chipset, especially when to enable the ATI mode or switching back to IBM mode, should fix LFB conflicts with various operating systems. 9.

Remove useless and crashy bios-less option of the Trantor T128. 11. The Image Manager 1024 card can also be used on a XT (although only if it has a V20/V30). 12. Re-organized the IBM PS/2 model 60 initialization as well as its right POS machine ID (though an update to sc.exe is still required for the POST memory amount to work normally).

ATI Mach32/64 changes for the better: 1. On both Mach'es: direct linear video memory access is now the default for LFB mapping: fixes Mach64 drivers on NeXTSTEP/OPENSTEP and keeps everything else intact. 2. Mach8/32: minor cleanup to mode change code.
2024-05-16 22:33:50 +02:00
Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Cirrus, ATI Mach8/32 and XGA fixes. 1. Update svga->fast to account for packed chain mode toggles, fixes issues on Descent II for DOS using the Cirrus cards. 2. Re-organized ATI Mach8/32 LFB access as well as 8514/A/ATI mode toggles, should end the video mode issues once and for all. 3. Fixed a small but major pattern issue with IBM OS/2 1.30.1's XGA driver (not .2, which is fine as is).

Mach32 changes of the day (February 20th, 2025) 1. Actually fix the LFB access by subtracting the linear base address from the current address when LFB/MMIO is on. This fixes blankness of certain Mach32 drivers on Win3.1x. 2. Apply a minor but important fix to the fonts used by said Win3.1x driver when the dpconfig activates bit 2 without bit 12 set (e.g.: 0x2255), ergo, issuing host data as monochrome without swapping it.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Even better (hopefully) way to fix the mode switches (November 3rd, 2024) 1. Added the missing call to mach32_updatemapping from port 0x3CF through its index 6. 2. If the accelerator DAC is active and the extended 256 color bit is on too then enable 8514/A mode when needed, otherwise it's VGA mode or decided by the passthrough/clock selection ports. 3. VGA DAC reads are redirected to the 8514/A DAC reads only when 8514/A mode is on.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8.

Video, Storage and MCA changes/fixes. 1. Cirrus Logic GD54xx, Paradise/WD VGA now reset the interlace once a text mode is issued if not done automatically. 2.

Small ROP fixes to both XGA and 8514/A. 8. Re-organized the mapping of the Mach32 chipset, especially when to enable the ATI mode or switching back to IBM mode, should fix LFB conflicts with various operating systems. 9.

Remove useless and crashy bios-less option of the Trantor T128. 11. The Image Manager 1024 card can also be used on a XT (although only if it has a V20/V30). 12. Re-organized the IBM PS/2 model 60 initialization as well as its right POS machine ID (though an update to sc.exe is still required for the POST memory amount to work normally).

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Cirrus, ATI Mach8/32 and XGA fixes. 1. Update svga->fast to account for packed chain mode toggles, fixes issues on Descent II for DOS using the Cirrus cards. 2. Re-organized ATI Mach8/32 LFB access as well as 8514/A/ATI mode toggles, should end the video mode issues once and for all. 3. Fixed a small but major pattern issue with IBM OS/2 1.30.1's XGA driver (not .2, which is fine as is).

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Changes to 8514/A compatible stuff (November 2nd, 2024) 1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled). 2.

Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

}
Fixing regressions of the mach32 (November 5th, 2024) 1. ATI Extended 8514/A mode may not use bit 5 of ATI reg 0xb0 sometimes but at the same time it won't use the standard VGA way of setting up 256+ colors, therefore, in the VGA DAC writes, use standard VGA way to revert to VGA mode in the writes instead of relying on bit 5 of ATI reg 0xb0 being enabled/disabled there. Fixes mode switches in VLB/PCI configurations using Windows 9x and possibly other stuff, ISA is unaffected and still works fine. 2. Added more logs and and remove/set I/O handlers correctly for the PCI side.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

More ATI accel fixes and undocumented stuff. 1. Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers. 2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

More ATI accel fixes and undocumented stuff. 1. Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers. 2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

mach_log("MCA reset.\n");
Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes of the day (January 26th, 2025) XGA: 1. Added a proper poll so to have its timings independent of the SVGA core and changes its renderer accordingly, mainly a blank render one. 2. Workaround the Ctrl-Alt-Del reset of Windows 2.x so that it switches back to VGA text mode correctly when using the 0xA000 64K aperture (in vid_svga.c). SVGA core: Re-organized the way the different timers are organized so that the XGA and 8514/A pollers can coexist with the SVGA timer without conflicts. ATI Mach32: Reworked the true color renderer and made it a Mach32 exclusive due to its differences from the standard one. Fixes wrong rendered colors in NT using the 32bpp renderer in RGB mode.
2025-01-26 14:25:35 +01:00

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

io_removehandler(0x03c0, 32, mach_in, NULL, NULL, mach_out, NULL, NULL, mach);
Fixing regressions of the mach32 (November 5th, 2024) 1. ATI Extended 8514/A mode may not use bit 5 of ATI reg 0xb0 sometimes but at the same time it won't use the standard VGA way of setting up 256+ colors, therefore, in the VGA DAC writes, use standard VGA way to revert to VGA mode in the writes instead of relying on bit 5 of ATI reg 0xb0 being enabled/disabled there. Fixes mode switches in VLB/PCI configurations using Windows 9x and possibly other stuff, ISA is unaffected and still works fine. 2. Added more logs and and remove/set I/O handlers correctly for the PCI side.

More video fixes: ATI Mach64 is temporarily unthreaded because of blitter desyncing. ATI Mach32 now returns to ATI mode from IBM mode and vice versa more correctly. Make the IBM 8514/A compatible poll not run if a 3D add-on card (Voodoo1/2) takes precedence (seen on a Mach32 PCI and Voodoo2 3D combo). Finally ended the mess ups of the TGUI9440/96x0 pitch, it actually was the CRTC offset reg (SVGA CRTC 0x13) that defined it with some shifting based on the BPP.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Cirrus, ATI Mach8/32 and XGA fixes. 1. Update svga->fast to account for packed chain mode toggles, fixes issues on Descent II for DOS using the Cirrus cards. 2. Re-organized ATI Mach8/32 LFB access as well as 8514/A/ATI mode toggles, should end the video mode issues once and for all. 3. Fixed a small but major pattern issue with IBM OS/2 1.30.1's XGA driver (not .2, which is fine as is).

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Mach32 and clock changes of the day (September 22nd, 2024) 1. Going from screenshots of the Mach32 chips, they all have the ati18811-1 clock regardless of the bus type, whilst the Mach8 has an ati18812, which is actually a ati18811-0 2. Unbreak the NS3.1 Mach32 driver, ergo, don't block the LFB processing.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5.

The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7.

Video changes part 1 for 4.2 1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone. 2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before. 3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff. 4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions. 5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate. 6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed). 7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x 8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.

Big video changes of the day (October 26th, 2024) 8514/A/Mach8/32: Reworked the acceleration a bit as well as the mode switches from VGA to ATI/8514/A mode and viceversa based on the documentation. Fixes the Linux GUI fonts using the Mach32 driver (possibly Mach8 too) and other anomalies (still needs more work on the acceleration though). PVGA: Minor fixes to the banking. S3-based (Pre-ViRGE): 1. Made the chip class use its own banking so that the Enhanced Mode mapping (equivalent to 64K-based A0000) is taken into account (per bit 3 of CRTC31, which forces the mapping to be 64K A0000, regardless of the GDCREG6 bits). Fixes NT 3.1 347.1's S3 driver. 2. Initial rework on 15bpp/16bpp accelerated mode of the 911/924 chips (currently not 100% bug free, I need help with this chips). XGA-1/2: Get rid of the linear endian reverse variable hack used by OS/2 and, instead, use the already declared ones more wisely, fixes OS/2 2.1 reversed fonts and keeps everything else working as it should. Misc: Added the BT481 RAMDAC for future card use.

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5.

ATI Mach8/32 mode changes and cleanup: 1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper). 2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff. 3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above. 4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI). 5. Added some comments regarding the current situation. 6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly. 7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.

Video features and fixes: Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)

Video changes: 1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM). 2. Implemented the MCA behalf of the Mach32 and its corresponding reset function. 3. Properly implemented (more or less) true color, including 24-bit BGR rendering 4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color. 5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine. 6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT). 7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB. 8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI. 9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA. 10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode. 11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead. 12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.
