In message: <[EMAIL PROTECTED]>There are currently three PCI standards, not including PCI-X. PCI2.1, PCI2.2, PCI2.3. (Again, not including PCI-X, this is only 32bit/33MHz.) On top of this, you have three voltage standards; PCI 5V, PCI3.3V, and PCI-Universal (3.3/5.) These are the -keying- of the slots. So I got out the PCI 2.3 specs, go to pp185. A PCI 2.3 slot is keyed at the front (towards the front of the case), as the P2B-DS is, and is 5V. A PCI 3.3V slot is keyed towards the rear (towards the I/O panel). Then there's PCI Universal; this a card-only specification, which has a double-keyed card (keyed front -and- rear) to be inserted in 3.3V or 5V slot. A universally keyed card should support either 3.3V -or- 5V normally.

Chances are good that you might have a problem. I have a few devices
that don't appear on one of my machines because the machines are too
old and not compliant with the latest PCI standards. I also have one
cardbus card that refuses to work on some machine due to, I think, bad
(no?) 3.3V power.
The Realtek 8169's I've seen are keyed universal, but is specifically a PCI 2.2 or later 3.3V card. A universal keyed PCB is apparently cheaper to make than a properly keyed card. The Asus P2B-DS is, as far as I have been able to find, a PCI 2.1 board.
