7.3 SCSI IDs
Each device attached to the SCSI bus, as well as the SCSI controller
itself, must be assigned a unique SCSI ID number from 0 to 15. A SCSI
ID uniquely identifies each SCSI device on the SCSI bus and determines
priority when two or more devices are trying to use the SCSI bus at the
same time.
Refer o the device’s documentation to set the SCSI ID. Here are some
general guidelines for SCSI IDs:
•
For internal SCSI devices, the SCSI ID usually is set by configur-
ing a jumper on the device.
•
For external SCSI devices, the SCSI ID usually is set with a swetch
on the back of the device.
•
SCSI ID numbers don’t have to sequential, as long as the SCSI con-
troller and each device has a different number.
•
For example, you can have an internal SCSI device with ID 0, and
an external SCSI device with ID 6.
•
SCSI ID 7 has the highest priority on the SCSI bus. The priority of
the remianing IDs, in descending order, is 6 to 0, then 15 to 8.
•
The on-boards SCSI interface is preset to SCSI ID 7 and should not
be changed. This gives it the highest priority on the SCSI bus.
•
Most internal SCSI hard disk drives come from the factory pre-set
to SCSI ID 0.
•
If you have 8-bit (or Narrow) SCSI deveices, they must use SCSI
IDs 0, 1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first SCSI
hard disk drive.
•
If you are booting your computer from a SCSI hards disk drive con-
nected to the SCSI bus, the Boot SCSI ID setting in the
SCSISelect utility must correspond to the SCSI ID of the deveice
from which you are booting. By default, the Boot SCSI ID is set to 0. We
recommend that you do not change this setting.
•
In Windows© 95/98, you can use the Device Manager to determine
which SCSI ID is assigned to each installed SCSI device.
