2.3.5 Setting SCSI IDs

You must set each SCSI device and the host adapter to a separate SCSI

ID, 0 through 15. SCSI ID 7 is the preset host adapter setting, giving it

the highest priority on the SCSI bus. If you plan to boot your computer

from a SCSI hard disk drive on the SCSI bus, that drive should have

SCSI ID 0, or the lowest SCSI ID on the bus. Chapter 3, Configuring the

Host Adapter, explains how to set the host adapter ID using the Symbios

SCSI Configuration utility.
