2-6Adaptec Ultra320 SCSI Cards User’s GuideInstalling Multiple SCSI Cards You can install multiple SCSI cards in your computer; you arelimited only by the available system resources (for example,IRQ settings, I/O port addresses, BIOS addresses, and so forth). Each SCSI card you install forms a separate SCSI bus with adifferent set of SCSI devices. SCSI IDs can be reused as long asthe ID is assigned to a device on a different SCSI card (forexample, each SCSI card can have a device with SCSI ID 2). If you have two or more SCSI cards and your computer bootsfrom a SCSI disk drive, leave the host adapter BIOS enabled onthe SCSI card to which the boot disk drive is connected. UseSCSISelect to disable the host adapter BIOS on the other SCSIcards. If you have two or more SCSI cards, you can choose which SCSIcard is found first by your system by physically changing theorder of the SCSI cards in the PCI slots. Your system scans thePCI slots in a set order.
