He's as sharp as they come, but I assure you he's most definitely not
the only person on earth who is capable of single-stepping in assembler
to reverse engineer a chunk of code. ;)

"Standard 25MHz multi-mode FC"? There are precious few standard fiber
communications modulation methods and "wire"-level protocols, and if
they designed a proprietary one to artificially keep costs high and lock
out competitors (which is the only real reason why they'd have done it)
then there's almost no chance of them having used any of the common ones.
Unless of course by "FC" you meant FibreChannel, which means it could
speak the standard FC protocol but implement a proprietary subcommand
set within the FC-delivered SCSI protocol. In that case, it could
likely be reverse-engineered with a FibreChannel protocol analyzer. I
suspect, however, that you know how much those cost.
What major chips are on the board? Anything standard, or all proprietary?
