[G4] Troublesome Sawtooth 2

[Snoke Jay S NPRI]

Chris-
	Try booting up with any OS install CD... Have you tried swapping drives?  Are there any other PCI cards in it? Might try removing all of them save for video... It looks like you've tried everything else. If it won't boot while trying any of those, I'd bet it's the board.
