- 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
- 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.
- 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 ])

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.
- 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
