Maybe the card isn't grounding the right PRSNT pins to allow the machine
to detect the presence of the card?

Robert,
I checked these pins. They are grounded.
I wonder if a Hot Plug slot doesn't have enough power to feed the card. I
measured voltages (12, 3.3 and 5). I saw a spark during power on, but this
spark never goes to a normal voltage level. For example, in the +12v pin I
saw a spark +3.5 volt.

Hello,
A PCI card, which developed in my company, isn't powered in a Hot Plug PCI
slot( Intel server ).
During boot-up, a populated slot powers up, then immediately powers off.
The card works fine in non Hot Plug slots. The Hot Plug PCI specification
says that a regular PCI card should at least be powered in a Hot Plug PCI
slot.
What are requirements for running a PCI card in a Hot Plug slot.
I would appreciate any help.
Igor
