Type 2 PCI device error

[rf1nley]

I have read that the PCI slots on the PCI riser on my DL360 G4 are PCI-X and are backwards compatable with all of the other types of PCI slots.  Is this a fact?

I pulled a soundblaster card out of another server and put it in my HP and got a boot error.  It said something about "Type 2 PCI device cannot be configured by BIOS and must be configured by OS or driver."  Then the boot freezes.

PCI-X is backwards compatible with everything EXEPT PCI conventional.  An old 5v card will fit but not work.  This is what I am finding.  Does it sound correct?

Slot #1 has to be occupied.  That was the problem.
