2cedd2d79f - fixed OAK driver problem in win98 
- CDs can boot at segment != 0x7c0
- reworked int19 in a C function
- "no emulation" CDs can be booted (Win2k, XP).
  No more 000E failure code. Win2k fails though
- started to implement int13 for cdrom
- started to mutualize string constants
- changed a little bit the Bios Config Table address
  so the new int19 handler fits whithout relocation

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.

77cdb18620 - add LGPL bios by Christophe Bothamy <cbbochs@free.fr>. When new versions 
are released, I will remove VGABIOS-cbothamy-0.2a and add a file with
  the other version number.  I decided not to use the "-latest" naming
  scheme because there is no synchronization between bochs releases and
  LGPL VGA BIOS releases.  Anything that's called "latest" is bound to
  go obsolete eventually.

fad446ef63 - fix bug I created in rev 1.15 which caused all boot problems to be 
reported as "not a bootable disk" even if it was "not a readable disk".

fea759a204 - apply patch.pci from Volker Ruppert. See 
[ #481546 ] pci patch (Volker Ruppert) for any followups.

c685af1bdc - in sync with rombios.c 1.20. The change is from patch.parport by 
Volker Ruppert which fixes parallel port access.

a2efc4c5de - commit patch.parport from Volker Ruppert. I tested it by running 
"copy FILE prn" in a freedos image.

7986ea67a7 - print "read error" when hard disk cannot read the disk image, or 
seeks beyond the end

7140fa7090 - don't panic on int 0x13, AH=0x42 through 0x49. These are valid 
MS/IBM extensions but they aren't supported.  Return an error code instead.

daf2a9fb55 - add RCS Id to header of every file. This makes it easier to know what's 
going on when someone sends in a modified file.

3bba2f657f - apply patch from patches/patch.lba. This is taken from plex86 cvs 
and modified for bochs.  Minimal testing so far...

aca0d3fae8 - 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

a11b18da3a - 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.
 2001-06-13 07:23:26 +00:00

7a095b60e4 - now floppy controller returns a proper error response if you try to write 
a read-only disk image.  For systems such as DOS that actually use the
  BIOS services, it was also necessary to add code in int13_diskette_function
  to recognize a write-protected error and return the correct error
  status code (AH=3, Carry Set).

7f14cc625e - This should fix the bug 
[ #430472 ] DOS HIMEM "A20 line" error
  All I've done is moved the call to print_bios_banner later in the
  boot process, and the A20 problem goes away.  I wanted it early so
  that it would get printed before any panic or halt could happen.
  Oh well.

8ab8c40108 - fix bugs in SMP structure 
- this file now corresponds with rombios.c version 1.12.

08fad0325e - fixed the entry count for 2 and 4 processor MP structure, and the 
checksum.
- at the same time, I removed my initials from the OEM id field and changed
  it to "BOCHSCPU"  :)

981fb8f55b - fixed bug introduced in 1.6 which caused MP structures to be overwritten 
by BCC generated data.  This was pointed out by Tom Lindström
  <tom@debet.shh.fi>, and I took his suggestion of moving the MP structures
  to the end of the file.

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.
