bc8ac37c63 Improved BX_INFO message for AGP aperture access. Since the Banshee AGP and
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).

c10e8feea6 Added support for driving the speaker line directly with the speaker gate, but
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.

95d0a182af Some work on the disk image sector size option based on a patch by Ben Lunt.
- Implemented sector size handling in the ATA disk emulation. This feature
  still needs BIOS support to boot from a disk with big sectors.
- Enabled sector size support in the redolog_t class based disk image mode.
  The base class can handle 512 byte blocks only, but that doesn't matter since
  all valid sector sizes are multiple of it. So for now the growing, undoable
  and volatile disk image modes internally read/write 512 bytes per call.
- TODO: BIOS, bximage.

ea7334bfab Sector size option implemented in the USB disk code. The sector size value must
be specified as a USB port option (e.g. 'sect_size:1024'). The values 512, 1024
and 4096 are supported. If not specified, it defaults to 512.

657cd05c0a Continued preparing hard disk sector size option in the hdimage code.
- 'flat' mode: disk image size must be multiple of sector size.
- 'concat' mode: each disk image size and lseek() offset must be multiple of
   sector size.
- 'sparse' mode: page size and lseek() offset must be multiple of sector size.
- TODO: 'growing', 'undoable' and 'volatile' mode: redolog_t class is still
  based on 512-byte blocks.
- TODO: 'vbox', 'vmware3', 'vmware4', 'vpc' and 'vvfat' mode have a builtin
  geometry. If other sector sizes are supported, it should be handled correctly.
- harddrv code now reports current sector size, but still panics for now.
- TODO: harrdrv and USB disk code, bximage, BIOS.

8952c144bd Some work on the i440BX chipset and related changes.
- Fixed PCI BAR initialization (now using memset()).
  - Fixed reset failure (set all PAM memory types to ROM).
  - Added stub for the AGP aperture (register BAR #0, handle APSIZE and read
    GART entry in read/write handlers).
  - Added some more PCI register defaults and write masks.
  - Fixed a warning in the ES1370 code.
  - Voodoo Banshee: set up PCI subsystem ID depending on bus and model.
  - Volatile BIOS write support must also be present in ISA BIOS memory.

e7093e74d8 Started implementing the i440BX PCI/AGP chipset.
- Added new PCI chipset choice for the i440BX AGPset. Some basic work is done,
  but AGP support is not present yet.
- Added new class for the "virtual" PCI-to-PCI bridge that should manage the
  secondary bus (AGP). Since this device must appear with device number #1 at
  the primary bus, it was required to change the PCI device numbers for the
  i440BX case. Moved the PIIX4 module to device number #7. The presence of the
  PCI base address regions now depends on the header type as expected.
- Since the Bochs BIOS cannot handle the modified PCI device layout, all tests
  continued with an external BIOS designed for this chipset (GA-6BA_F1.bin).
  This BIOS requires additional changes in some devices.
- ACPI: Return value 0 for some status registers and the GPI registers.
- CMOS: Since the PIIX4 supports a 256 byte CMOS RAM, prepared support for it
  and enable it in case a 256 byte CMOS image is used.
- PCI: The device numbers for 4 slots starting at #8. The 5th slot could be
  used for AGP when available.

05da2a4dff Added basic support for the Voodoo3 model (Banshee plus secondary TMU).
Using a temporary subsystem ID, since I haven't found a VGABIOS ROM image for
the PCI version and Bochs doesn't support AGP yet. After modifying Voodoo3.inf
the driver could be installed successfully in Win95/98 and the Voodoo3 works as
expected (same issues as the Banshee model).
Removed BX_ERROR message about setting undocumented srcXY register bits. They
seem to have no effect on the emulation and could be ignored.
