834904f49b - improved HD recognition and CD boot (patches by Myles Watson) 
* fixed minor error from printf patch confusion (negation based on wrong word)
  * added helper function await_ide
  * changed lba calculation to not corrupt lba (for debugging and clarity)
  * added support for partial completions of ata_cmd_packet (never happens in
    the simulator, but happens all the time in hardware)
  * update atapi_request_sense and atapi_is_ready - based on FILO
  * correct an int 15 call that should have been int 0x15
  * trivial fix when BX_PCIBIOS and BX_ROMBIOS32 not defined
- implemented %X in bios_printf (patch by Sebastian)

fc6693001c - rombios patches by Myles Watson <mylesgw@gmail.com> 
* corrects a spelling error and removes the lba_capable comment
  * moves dpte_segment after dpte_offset (endian problem) in the struct
  * changes int13 0x15 to use the logical geometry instead of physical to
    return sectors
  * clips cylinders in Int13DPT
  * fixes bit shift problem in options (parens in the wrong place)
  * returns the correct offset for dpte.iobase2
  * fixes a pointer arithmetic error in calculating the checksum of the dpte
  * moves #if BX_SUPPORT_FLOPPY to include more floppy code
  * added support for %lx %ld and %lu for bios_printf()
