Intel® Xeon® processors 5400 and 5200 series require specific hardware and software revisions on the following Intel® Server Boards and Platforms:
I saw that article as well. While I get the BIOS part (the article sates BIOS 84 or higher is required and mine is currently at 86), the rest of it means little to me. Does it mean that there are certain manufatured runs of the board that will work and others that will not?

PBA# is hardware revision. It's printed on a barcode label on your board. If your PBA# is Dxxxxx the it doesn't support Xeon 5400 series processor.
That appears to be my problem. Thanks for the help.
