Well ... There is one (IMHO) ugly way if you can't get specs from the
manufacturer:
If you have an MS-DOS floppy you can boot with the BIOS supplied by
the board manufacturer, you could always use a combination of DEBUG (to
locate the code and save it to a file) and IDA (a freeware/shareware
Interactive DisAssembler) to re-create source code.
