I'm on Rev 1 as well, agrafuese. What does your About Mac say in the Firewire section? Mine just says "set to 400mbs speed" or something to that effect. I only have one Firewire device (a Sony camcorder) so I haven't determined whether I'm not correctly configured or if my device just isn't supported properly.

Thank you for the link, alphabeta23! That gives me a chipset that works for sure. Might be ordering another card.

Maybe I need to play around with the BIOS settings to see if a certain combo of settings let them work.
