At the end of the day, the issue is that the P5QPL-VM EPU IS NOT COMPATIBLE WITH ADD ON CARDS IN THE x16 SLOT!
No kidding, Asus told me that it does not support non-graphic cards in the x16 PCIe card slot.
...I'm current waiting to see if they are going to make it right by giving me a different product.
Currently, they've blamed it on Intel, and, since I have contacts at Intel, I'm looking to see if this is actually an Asus implimenation issue. (More likely, considering the fact that I'm using an Intel PCIe NIC, with the Intel G41 North/ICH7 combo, and the built in Intel IGM.
