549d052e34 VGA_MEM_FIX: Picked a better name for the sequencer odd/even disable switch. 2024-02-11 14:49:12 +01:00

0e5800bf98 VGA_MEM_FIX: Fixed cursor address of the invisible cursor. 
Now using the highest address of the default text mode buffer.

39155bd3ae VGA_MEM_FIX: Temporary fix for special memory access mode in modeX. 
In odd/even mode fall back to planar mode if "chain odd/even" bit is 0.

945ee597f0 Added currently disabled set of fixes for the VGA memory management. 
- Added disabled definition VGA_MEM_FIX in vgacore.h. The VGA core code works as
  usual unless you uncomment the define.
- Added correct implementation of the "chain four" and "odd/even" addressing mode.
  This should fix the Debian / GRUB boot issue (#257) with both Bochs VBE and Cirrus.
- Added some compatibility code to make the gui text update work as usual.
- Tested all VGA modes except 256-color word mode (no test case).
- Some more testing with old DOS games may be required before I enable it by default
  and finally remove the legacy code.

4e6b4165f5 Added workaround for the save/restore function of the GRUB bootloader. 
The VGA core needs an extensive rewrite to support it correctly with
both Bochs VBE and Cirrus.

TODO (for other devices):
