94 Chapter 5 SCSISelect Utility The default values for the AIC 7899 SCSI Bus Interface Definitions are: SCSI Bus Interface Definitions Host Adapter SCSI ID SCSI Parity Checking Host Adapter SCSI Termination Default Value 7 Enabled Enabled Host Adapter SCSI ID This option allows you to change the host controller SCSI ID. The default setting is SCSI ID 7. (We recommend that you not change this setting.) Some operating system software will not run unless the SCSI controller ID is set at 7. Each SCSI device on the SCSI bus, including the SCSI controller, must be set to a unique SCSI ID. The SCSI ID serves two purposes: it uniquely identifies each SCSI device on the bus, and it determines the device's priority on the bus during the Arbitration phase. The Arbitration phase determines which device controls the bus when two or more devices request use of it. SCSI Parity Checking Select this option to enable or disable SCSI Parity Checking on the SCSI controller. The default setting is Enabled. The SCSI controller always checks parity when reading from the SCSI bus to verify the correct transmission of data from your SCSI devices. You should disable SCSI Parity Checking if any attached SCSI devices do not support SCSI parity. (Most currently available SCSI devices do support SCSI parity.) Host Adapter SCSI Termination This option allows you to configure host controller SCSI termination Boot Device Options This option shows the target ID of the device you are booting from.

The default values for the AIC 7899 SCSI Bus Interface Definitions are:
Host Adapter SCSI ID
This option allows you to change the host controller SCSI ID. The default setting is
SCSI ID 7.
(We recommend that you not change this setting.)
Some operating
system software will not run unless the SCSI controller ID is set at 7.
Each SCSI device on the SCSI bus, including the SCSI controller, must be set to a
unique SCSI ID. The SCSI ID serves two purposes: it uniquely identifies each
SCSI device on the bus, and it determines the device's priority on the bus during
the Arbitration phase. The Arbitration phase determines which device controls the
bus when two or more devices request use of it.
SCSI Parity Checking
Select this option to enable or disable SCSI Parity Checking on the SCSI
controller. The default setting is
Enabled
.
The SCSI controller always checks parity when reading from the SCSI bus to
verify the correct transmission of data from your SCSI devices. You should disable
SCSI Parity Checking if any attached SCSI devices do not support SCSI parity.
(Most currently available SCSI devices do support SCSI parity.)
Host Adapter SCSI Termination
This option allows you to configure host controller SCSI termination
Boot Device Options
This option shows the target ID of the device you are booting from.
The default
setting is
0
(zero).
We recommend that you not change this setting.
Some
operating systems will not run unless the boot device is set at zero.
