I'm looking for a suitable 1394 Firewire adapter for the Dell 670 Workstation that will plug into a PCIX slot. IIRC the PCIX is 64-bit, and that's what's needed for 800 MBps? The 670 already has Firewire but it's 6-pin and 400 speed. My new Passport Studio has Firewire 9-pin jacks. It could work with an adapter cable to 6-pin jack on the PC but I'd like full tilt 800. Please advise.. the PCI spec confuses me, especially PCIX. -Ed p.s. what happened to the Adaptec 8300 board? That would be preferable.
