Voodoo3 AGP driver I have tested are not using this feature, we don't have a
test case yet to implement it correctly. The GART is used by AGP and the newer
PCIe bus and the specs say that the format is defined by software (driver).
the square wave generator disabled. This feature has been used by old demos and
games to play digitized sound before soundcards with DSP became popular.
- rombios.c: return maximum bus number #1 for i440BX.
- Now using different i/o and memory base address regions for PCI and AGP.
- Added some init code for the i440BX PCI/AGP bridge.
- Some code cleanups.
- rombios.c: return maximum bus number #1 for i440BX.
- Now using different i/o and memory base address regions for PCI and AGP.
- Added some init code for the i440BX PCI/AGP bridge.
- Some code cleanups.
- Bochs BIOS: Improved calculating PCI slot number from device number to handle
the i440BX case correctly.
- Memory code: Detect and modify the PCI IRQ roouting table of the Bochs BIOS
for the i440BX chipset (TODO: this could be done by the BIOS itself after
copying to shadow RAM).

- Added symbols for the i440BX host bridge device ID.
- Probe and search for devices on PCI bus #1 (AGP).
- Set up memory and i/o regions only for header type 0.
- Set AGP aperture size to 64 MB.
- TODO: PCI IRQ routing, i440BX specific register setup.
- Added symbols for the i440BX host bridge device ID.

- Set AGP aperture size to 64 MB.
- TODO: PCI IRQ routing, i440BX specific register setup.
- Function ata_cmd_data_io: using fixed block size 512 only for 'identify'
commands. For read/write commands the hard disk sector size must be used.
- Take account of sector size when calculating hard disk size in MBytes (TODO:
calculation is not correct for not yet existing very big disks).
- updated comment.

- updated comment.
- Added default value for the video clock frequency to make sure that the
vertical timer works.
- Changing vidDesktopStartAddr register when the video processor is on now
forces a screen update.
