aa57c0e171 - most important functions of the protected mode PCI BIOS added. 
Linux (kernel 2.2.18) is able to use the new features.
  Here is the list of changes:

  * BIOS32 data structure added
  * BIOS32 and protected mode PCI BIOS functions added. The BIOS32 function
    returns a pointer to the PCI BIOS entry point when the service $PCI is
    requested and the PCI hardware is present.
  * Supported 32 bit functions: installation check, find pci device,
    read configuration byte/word/dword, write configuration byte/word/dword
  * real mode PCI BIOS installation check rewritten in assembler to use 32 bit
    registers for the protected mode entry point and the 'PCI ' signature.

  TODO:

  * add missing functions of the PCI BIOS (if necessary)
  * add missing features of the i440FX PCI bridge
  * implement the other parts of the i440FX chipset (PCI-to-ISA bridge,
    PCI IDE controller, USB controller)

c2941ec36b - added error message: PCI BIOS can only be used with 386+ cpu 
- functions inw() and outw() are required for the ATA driver too
- real mode PCI BIOS installation check returns revision level 2.10
- unsupported real mode PCI BIOS functions return the error code 0x81

2f2f9880ca - compiled rombios.c 1.54 
- added BX_DEBUG, BX_INFO, BX_PANIC macros
  - BX_DEBUG outputs to the INFO port till we can easily choose debug output on a per-device basis
  - BX_DEBUG are only generated if DEBUG_ROMBIOS is defined to 1
  - do not panic on unsupported function in int13, only output info message
  - fixed a bug on boot signature check never done on floppy/harddisk and always on floppy images on cd
  - the boot signature check on harddisks is always done
  - the boot signature check on cdroms (either direct boot or floppy images) is never done
  - the boot signature check on floppies is conditionnal to CMOS reg 0x38 (configuration floppy_bootsig_check)
  - moved PIC initialization before calling optional rombios init functions (feature request [ 541908 ])

8ceca1a4c5 - change a few keyboard panics into printfs (warnings). I got a bug report 
about this, #535432: Emu panics when pressing ">"-key.  The user did not
  report exactly what the exact message was, but these sound like the
  correct ones.  BIOS panics are permanent fatal errors, so I don't
  want them to show up accidently, especially for something as trivial
  as bumping the wrong key.

26b2c0254c - this revision is based on a patch from Cliff Hones <cliff@aonix.co.uk>. 
Cliff added to bios_printf the ability to print onto the console.  Bryce made
  some further changes.  Now when a panic occurs, the message is reported both
  to the Bochs log file and to the screen, and then it goes into an infinite
  busy loop.  Why an inf loop?  If I do a HLT in BIOS code, current bochs
  versions will panic immediately and the user will never see the real panic
  message.  I have mostly tested the new panic behavior by booting nonbootable
  and nonreadable disks.

36d6a6527e - update bios again, but this time move to a standard filename 
BIOS-bochs-latest.  Different versions of the BIOS can now be
  distinguished because they print the RCS ID into the log file
  using bios_printf.
