I can't remember the details but it was something to do with 'main' and backup BIOSes.
It was an old board, took a Q6600-era chip, but I can't remember the board. Pretty sure it was a Gigabyte though.
That said, I don't want to get your hopes up and it may be nothing to do with your problem.
Trouble is, I no longer have that board (I don't think) and cannot remember what the damn "trick" was. Not even sure it was official, but it worked.
I'll see if I can xredge my memory but .... :(
