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.

db95a54238 Prepared config interface for a hard disk sector size option.
This code is based on the initial patch by Ben Lunt with some modifications:
using enum parameter, extra parser handler and cdrom handling not necessary,
TODO: hdimage and bximage code, harddrv and USB disk emulation, BIOS.

e639d9dd29 Report AGP model in PCI status, new PCI capabilities and strapInfo register.
AGP specific features are not present yet.

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.

73bc76072e Added support for assigning a device (banshee or voodoo3) on Bochs PCI slot #5
to AGP if chipset i440BX is selected. AGP-specific features are not implemented
yet.

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.

04981c35d3 Added the subsystem ID of a Voodoo3 PCI model to make it work with an external
VGABIOS image in Win95/98 guest without hacking. Mention the Voodoo3 model in
the docs.

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.

bb472a78f9 Some work on the Voodoo Banshee emulation and related changes.

- Fixed calculation of the pitch for packed source data.
- Fixed repeated execution of some commands in non-immediate mode.
- PCI devices: fixed and improved BX_INFO / BX_DEBUG messages.

- Added INT pin init to method init_pci_conf().

87145baf61 Rewrite of the PCI base address (BAR) handling to reduce code duplication.
- Added new structure bx_pci_bar_t that contains all parameters related to the
  PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
  in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
  BARs and the ROM BAR. Writes to other registers are forwarded to the device
  specific PCI write handlers. Removed BAR and ROM BAR handling from the
  specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
  update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.

Stanislav Shwartsman
e8d0e718f1 continue param tree changes
take RAW_BYTES string out of bx_param_string_c into new param type bx_param_bytestring_c (better name, anybody?)
this is intermediate step, later it would be better to merge bx_param_string into generic template bx_param<type>
but bx_param_bytestring_cis not matching that concept (or probably will continue to inherit from bx_param<string>)
