by Bochs BIOS).

bab68dbb2b Some small changes on the Voodoo Banshee emulation.
- Access to VGA registers via Banshee address space is not memory mapped.
- Added BX_ERRORs for unimplemented unaligned access to i/o registers.
- Access to the unimplemented YUV address space now causes BX_ERROR.
- Removed some TODO comments.

2045ead0ce Improved error handling of the user shortcut feature.
- Shortcut parser sets a flag in case of error.
- String parameter handler resets to old value if the new one is invalid.
- User button handler shows a message box if the parser signals an error.

1d0efc734f Some work on the Voodoo Banshee emulation.
- New attempt to fix the host-to-screen bitblt issue with monochrome source.
  The specs are wrong at this point. The rules for calculating the real source
  pitch are still unknown. These hacks should fix most the glitches.
- Added source colorkeying support for host-to-screen blt with pattern.

49f8624898 Some changes in the Bochs BIOS.
- Disable i/o and memory access in PCI command register before probing and
  setting up base addresses and re-enable it when complete for selected device.

98e10e0bab Some changes in the Voodoo code.
- Banshee: Added colorkey support for host-to-screen blts without pattern.
- Clearing base address registers in reset is not okay. Maybe we have to
  unregister i/o and memory regions here. This affects other devices, too.
- Some other small changes and typo fixes.

e8e9cd03a3 Some work on the CMDFIFO "byte disable" (Voodoo2) / "byte enable" (Banshee)
feature of packet type #5. Added some W2 cases for texture writes, modified

f845457362 Implemented usage of the color lookup table (CLUT) for gamma correction during
video refresh in 16 bpp modes. The Banshee also uses this feature in 16 bpp
desktop mode in addition to 3D modes. The code for the pen calculation comes
from the original Voodoo patch for DOSBox. Since it was unused there, I had
disabled it when porting to Bochs.
