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).
* 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.
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)
XGA: Fix crash when (S)VGA cards not selected as the primary display (e.g.: EGA, CGA. etc).
Better handling of the VGA on/off passthrough (vga_on variable).
MCA side: to avoid lfb issues, bit 0 of POS4 will be always enabled regardless of the ram size (most software uses the >16MB memory method).
Better handling of the BIOS ROM mapping and Memory Mapped I/O during the MCA PS/2 POST and resets, fixes 40 25 hang (once and for all).
Re-organized the ROM loading in ISA mode.
ESDI MCA: Increased esdi_time from 200 to 512, should fix the timeout that caused the bad attention 03 fatal.
Rancho: Added the Rancho RT1000B-MC MCA SCSI controller, it uses the 8.20R BIOS.
8514/A: Reworked the Outline command to satisfy the manual and the win2.10 (286/386) driver.
XGA: Initial rom len is set to 0x8000 (which, after being configured, is set back to 0x2000) just to not make it hang with POST code 40 25 on most configurations.
Cursor and mapping on Windows 2.x' 286/808x XGA driver.
Pattern and DMA bus master fixes to OS/2 2.x/Warp's XGA driver.
Software reset no longer causes glitches to the screen using XGA (x86.c)
