The Netfinity 3000 ships with a SCSI controller. If you're booting to the NetRAID card, the BIOS for the standard SCSI controller should not load. You can disable it via Ctrl+A when you see the prompt. To lock down the IRQ, highlight the setting (auto) for the NetRAID card (or Slot - I can't remember offhand) and press "Enter" You should see your options. Select something normally unused (like 5 - secondary printer port), then save and exit. You're right, Netfinitys don't let you change the boot order, so you either have to move the card to a Slot that is scanned before the SCSI controller, or disable the SCSI BIOS (or both - my preferred methodology). Locking down the IRQ will avoid conflicts with everything else set to "Auto", trying to share an IRQ - I don't like my I/O device losing in a "shared" environment.
