This is a new one for me. I've got a dual 2.0ghz G5 w/3 gigs of memory runnning 10.3.9 I've got a dual channel SATA card running a 500gig raid0 drive array. In slot 4 I have a firewire card. The reason for this is that I have an AJA io on the internal 400 bus, and a couple hard drives on the card, along with a DV deck. Yesterday I came in, booted up, and the firewire card wasn't showing up in the system. I repaired permissions, rebooted into safe mode, rebooted regularly, and the card came back. This mornign same problem, did the same thing (repair, safe boot, reboot) and still no card... any ideas?
