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

Installing Multiple SCSI Cards
■
You can install multiple SCSI cards in your computer; you are
limited 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 a
different set of SCSI devices. SCSI IDs can be reused as long as
the ID is assigned to a device on a different SCSI card (for
example, each SCSI card can have a device with SCSI ID 2).
■
If you have two or more SCSI cards and your computer boots
from a SCSI disk drive, leave the host adapter BIOS enabled on
the SCSI card to which the boot disk drive is connected. Use
SCSI

to disable the host adapter BIOS on the other SCSI
cards.
■
If you have two or more SCSI cards, you can choose which SCSI
card is found first by your system by physically changing the
order of the SCSI cards in the PCI slots. Your system scans the
PCI slots in a set order.
