I know this stinx, but that board only has 2 FireWire ports. I think you can only connect one of the rear ports if you want to use the front port.
Yesterday I was looking for a PCI card that would accommodate the front FireWire header, but in the brief time I spent I didn't see one. If anyone knows of one could you help the two of us out?
P.S. Whatever you do DO NOT connect the front port FireWire header to one of the USB ports on the mobo, I'm pretty sure its also states this in the mobos directions.
