  * int09_handler: pusha before int15, ah=4f
     (for "jis_a01" japanese keybord driver, which breaks some registers)
  * int15_function: add new functions int15_function32, int15_function_mouse
     (to avoid stack overflow ... DOS/Win9x works better)
  * int16, ah=00/01/10/11 ignore special key code (F0)

  * media type and geometry can be set for the floppy type
  * BIOS changes to make 360k floppy drives work
  * bximage can create 360k images now

- jump to POST entry point must be a far jump (MS-DOS and Win95 reboots now)
- keyboard init: read output buffer and enable keyboard before self test

- real mode PCI BIOS functions rewritten in assembler
- new real mode PCI BIOS functions: find device, read/write byte/dword
- C code for PCI BIOS handles errors and prints messages only
- function setPCIaddr() no longer needed
- functions inw() and outw() no longer used by the PCI BIOS

  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.

    read configuration byte/word/dword, write configuration byte/word/dword

    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)

- 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

- updated with rombios.c v1.56

- 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 ])

- fixed win2k boot from cd bug

with bug 433003 fix

- Dave Poirier fixed bug #466292: kbd fails in scandisk, freedos edit.
  I recompiled the BIOS with the fix.

- added fix for freeBSD boot

- 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.

- apply Christophe's patch.rombios-no-gpl
- update binary bioses
- remove the patch from patches

- update to rombios.c 1.40, with right version number this time!

- update to rombios.c 1.40

*** empty log message ***

- removed unnecessary delay loop after keyboard reset in POST

- fixed a unnecessary check on the bootsegment
- renamed int13_function to int13 harddisk
- the default is now to have the ATA driver and ElTorito boot

- keyboard self test reads the status register to clear IRQ line
- PS/2 mouse hack removed - unmask IRQ in PIC setup
- commented keyboard buffer initialisation removed

- floppy hardware interrupt handler issues 'sense interrupt status' if there
  are no result bytes to read

- INT 13: number of drives is not 0 if there is only a diskd present
- hard_drive_post: DS must point to EBDA segment when initialising
  parameters for diskd
- unmask only necessary IRQs at boot time

- romscan routine from plex86 BIOS integrated

- DMA initialisation complete: unmask cascade channel

- INT 13 diskette funktion 5 uses the "format track" function of the FDC
- added initialisation of PIC and DMA in POST - reboot of linux works now

- int 13 floppy function 08 returns always the pointer to the param table in ROM

- update to rombios.c version 1.25

- extended keyboard funktion waits for a key, too - don't panic

- serial functions added, MF-II keyboard functions added, parport updates

- 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.

- apply patch.pci from Volker Ruppert.  See
  [ #481546 ] pci patch (Volker Ruppert) for any followups.

- in sync with rombios.c 1.20.  The change is from patch.parport by
  Volker Ruppert which fixes parallel port access.

- print "read error" when hard disk cannot read the disk image, or
  seeks beyond the end

- apply patch from patches/patch.lba.  This is taken from plex86 cvs
  and modified for bochs.  Minimal testing so far...

- apply BIOS patch from Barry Allard to check the boot signature
- fiddle with I/O handler for port 0x401 to allow BIOS to write a
  complete panic message

- in int13_diskette_function, return the right error code (AH=3) if a
  write fails because the floppy disk was write protected.  Before, the
  floppy.cc model was unable to return this error, but now it can.

- compiled bioses for rombios.c revision 1.13

- print messages in log on boot failure

- 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.
