[KLUG Members] re: PCI riser card causes machine not to power on

[Kevin Mitchell]

Guess I wasn't clear enough.

I have a 2U rackmount machine that has 5 64 bit PCI slots in the 
motherboard.  To install any PCI cards, you need to use a riser card. 
There was a 100mb ethernet card in the machine that was installed using a 
32 bit riser card.  I want to put in a gig card, so I removed the 100mb 
nic and the 32 bit riser card and put in a 64 bit riser card.  After doing 
that it won't power up.  I tried inserting the gig card in directly 
(leaving the top of the case off) and it powers up just fine.  I tried 3 
different 64 bit riser cards (all of the same model) and none of them 
work.  It looks like some types of 64 bit riser cards just don't work w/ 
this motherboard.  Weird.

Just for reference.  The motherboard is a Tyan S2462.
