b3d0c18838 - int 15 / ah=87h should not clear cr0 when setting bit 0 (SF patch #969967 
by Ben Lunt)

9956e47f3e - modified the bios / vgabios panic handling. BX_PANIC messages sent by the bios 
now appear correctly as the Bochs panic message. Now we can get rid of messages
  with the line number in the source file.
- updated / fixed description in biosdev.cc

e5761d230c - calculate checksum of expansion rom (must be 0) 2004-09-03 19:52:24 +00:00

b4fbbe3af1 - implement int15, ah=83 Start/Stop Wait Timer (patch.rombios.markevich from Kory Markevich) 
- applied patch from sava (t.ebisawa / http://ebisa.hp.infoseek.co.jp/bochs/arcs/bochs-2.1.1-jpfix-20040214.zip)
  * 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)
- set missing return value and flag for unimplemented EISA BIOS

40e576cbb3 - A20 gate control implemented (int 15h, ah = 24h) 
- debug message for unsupported EISA bus features added (int 15h, ah = d8h)
- moving rom scan loop to a separate function saves space in the main post code
  (TODO: add code for rom checksum)
- interrupt vector 0x79 set to 0 (TODO: some other vectors seem to be 0, too)

- ne2k: unnecessary reset call in init() removed
- usb: don't execute reset if disabled

7fde35e253 - fix a bug reported on ML by Scott Duplichan. Unimplemented int15 calls 
should return AH=0x86 and CF set.  The new AH=E8 calls did not return
  0x86 in some cases where the call was not implemented.

4a7303c896 - update all bioses to current rombios.c 
- since rombios.c also supports 8 processors, go ahead and build an 8 cpu
  bios as well.

54a5e86cc6 - 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
- BIOS32 checksum calculation rewriten to prevent errors
- labels of protected mode PCI BIOS renamed

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)
