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)

fda1b874e9 Check in FETCHDECODE Caching, with changes.
Specific changes from the patch:

1.) renamed fdcache_eip to fdcache_ip, as it is using
the RIP instead of the EIP.

2.) added a Boolean array fdcache_is32 which uses is32
to determine icache hits.  Otherwise we could run 32-bit
code as 16-bit or vice versa.

1bd3646867 - implementation of the PCI device register mechanism
The new function register_pci_handlers() is similar to the register functions
  for i/o addresses. A PCI device can register the read/write handlers for it's
  private PCI configuration space. The i/o mapped registers of the host bridge
  control the access to the configuration registers of each PCI device. You can
  select the bus, device, function and register address with the confAddr
  register. The confData register is a window to the configuration space of the
  selected device.
- reset sets the values of the i/o mapped registers to 0
- changed some BX_INFO messages to BX_DEBUG

b30fdb2487 Fix problem with PIT when the machine is being really slow.
This means that the REALTIME_PIT now only works on machines
that are capable of sustaining 150000 IPS, in aggregate.  This
seems a reasonable requirement, as even my 200Mhz PPC with 16MB
of memory can sustain that.

This is now probably ready for primetime, so I need to get it
added to the configure options.

d1fbbd6f5c - include patch from Tal Benavidor :
this little patch brings a significant speed improvement to
  the bximage utility. when bximage creates a disk image, it writes
  a lot of zeros. actually as much zeros as the size of the image file.
  this takes quite a while for large images (at least in my win98/cygwin box).
  a faster way to create the image file is to seek to its end and write a
  single byte.
  to see the speed improvement, create a 100mb image with the old bximge.
  then apply this patch and do the same.

e92fb8deff Updated realtime PIT code.
This seems to work, but I don't think it works on slow machines (like mine.)

At least, I'm getting fails with the dlxlinux image, but they're pretty
sporadic.  This code shouldn't cause any fails.

a8fc8f8d84 - cleaned up and improved the X gui text font handling
* dimension_update() stores the global variables columns, rows and
    font_height_orig; it uses X font sizes to recalculate the screen size
  * text_update() uses the columns, rows and X font sizes when redrawing the
    screen; it adjusts the cursor shape using the font sizes

45ad28ff24 - adapted rombios for floppy boot signature check flag change
- added ASM_START / ASM_END instead of #asm / #endasm.
  Now we are (tested) able to compile with both gcc2 and gcc3
  compiler (Eventually!) Aren't you happy Jeroen ? ;-)
- fixed [ 549815 ]. I included back int19_relocated at the bios
  space could not hold the new mov ex, ax
- int19 calls int18 if the boot has failed. I hope this is the
  right behavior.

b84c82e80c - changed the floppy_bootsig_check syntax to be more logical. the syntax is now :
floppy_bootsig_check: disabled=[0|1]. It is not disabled by default.
  Sorry for any inconvenience it could cause
- changed the default (if cmos reg is 0) behavior for the floppy boot signature
  check, so the new bios is compatible with older bochs binaries (useful if we
  want to use the new bios when we release 1.4.1) :
  1 : disabled
  0 : enabled
- added info at launch time about the boot device and the floppy boot signature
  check
- added a "LBA capable" flag in the ata controller
