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.
