Re: PC bios recognizing PCI card

["Kevin Brace" <kevinbraceusenet@hotmail.com>]

Two more things to add to my original reply.
Try to stick a probe to the clock pin of that slot where the card in 
question is located.
If you don't see the clock signal, then somehow the clock distribution is 
being cut off.
Also, check IDSEL pin of the slot because if IDSEL isn't 'H' during the 
address phase of a Configuration cycle, the card won't respond at all.
