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)

Accelerator fixes part 2: 8514/A. Mix patterns are drawn at the correct position now instead of backwards. Better handling of subsys/subcntl side. As usual, better handling of the VGA on/off passthrough. Better handling of the accelerator pitch (TODO: need a way to properly identify 640x480x256 in the pitch side).

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, 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).

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).

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)

8514/A and XGA handling refactor: * separate (ibm8514|xga)_enabled into (ibm8514|xga)_standalone_enabled and (ibm8514|xga)_active, the former being enabled only for standalone 8514/A or XGA cards, the latter for all 8514/A and XGA-capable cards and not saved into the config file; * remove (ibm8514|xga)_has_vga and replace all uses of it with (ibm8514|xga)_standalone_enabled; * Qt UI: the checkboxes for standalone 8514/A and XGA are now correctly grayed out if an (S)VGA card with 8514/A or XGA capability is selected, including cases when the card is an internal/onboard one; said cards are now no longer appear as SVGA multi-monitor compatible.

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.

Accelerator fixes part 2: 8514/A. Mix patterns are drawn at the correct position now instead of backwards. Better handling of subsys/subcntl side. As usual, better handling of the VGA on/off passthrough. Better handling of the accelerator pitch (TODO: need a way to properly identify 640x480x256 in the pitch 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.

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 and more video changes and fixes (8514/A and compatibles): 1. Made the 8514/A mode switch to VGA and viceversa (including ATI mode) actually usable and eliminating the last bugs related to them. Fixes 8514/A mode in OS/2 1.x/2.x (both IBM and Microsoft). 2. More sanity checks to the 8514/A and XGA pointers. Should fix emulator crashes on hard resets.

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 and more video changes and fixes (8514/A and compatibles): 1. Made the 8514/A mode switch to VGA and viceversa (including ATI mode) actually usable and eliminating the last bugs related to them. Fixes 8514/A mode in OS/2 1.x/2.x (both IBM and Microsoft). 2. More sanity checks to the 8514/A and XGA pointers. Should fix emulator crashes on hard resets.

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: 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: 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: 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: 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: 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 8514/A related fixes: Replaced svga->bpp == 24 with dev->accel_bpp == 24 as well as proper ATI graphics engine offsets added to 24bpp mode in the 8514/A rectangle fill commands (cmd 2, 3, 4) as well as on a command val of 8514/A bitblt (mainly 0xc2b5, actual cmd 6). This should fix 24bpp mode under Windows/NT and other operating systems, like OS/2 2.x/Warp.

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: 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.

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.

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).

More 8514/A related fixes: Replaced svga->bpp == 24 with dev->accel_bpp == 24 as well as proper ATI graphics engine offsets added to 24bpp mode in the 8514/A rectangle fill commands (cmd 2, 3, 4) as well as on a command val of 8514/A bitblt (mainly 0xc2b5, actual cmd 6). This should fix 24bpp mode under Windows/NT and other operating systems, like OS/2 2.x/Warp.

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, 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).

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: 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: 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.

8514/A changes: Reduced the number of variables that depend on the main SVGA handler. Re-implemented accel command 5 (Polygon Boundary Line) right. Implemented Polygon fill type A and B (latter not tested yet) on accel command 2 per manual. Fixed crashes when starting Win2.1x using the built-in 8514/A driver. Some wip cleanups.

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.

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.

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.

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.

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: 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.

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.

8514/A and XGA handling refactor: * separate (ibm8514|xga)_enabled into (ibm8514|xga)_standalone_enabled and (ibm8514|xga)_active, the former being enabled only for standalone 8514/A or XGA cards, the latter for all 8514/A and XGA-capable cards and not saved into the config file; * remove (ibm8514|xga)_has_vga and replace all uses of it with (ibm8514|xga)_standalone_enabled; * Qt UI: the checkboxes for standalone 8514/A and XGA are now correctly grayed out if an (S)VGA card with 8514/A or XGA capability is selected, including cases when the card is an internal/onboard one; said cards are now no longer appear as SVGA multi-monitor compatible.
