SCSI Bus Interface Definitions

Host Adapter SCSI ID—(Default: 7) Sets the SCSI ID for the
SCSI card. The Adaptec SCSI Card 29160 is set at 7, which
gives it the highest priority on the SCSI bus. We recommend
that you do not change this setting.
SCSI Parity Checking—(Default: Enabled) When set to
Enabled, verifies the accuracy of data transfer on the SCSI bus.
Leave this setting enabled unless any SCSI device connected to
the Adaptec SCSI Card 29160 does not support SCSI parity.
Host Adapter SCSI Termination—(Default: Automatic) Deter-
mines the termination setting for the SCSI card. The default
setting for both the LVD/SE and SE connectors is Automatic,
which allows the SCSI card to adjust the termination as needed
depending on the configuration of the connected SCSI devices.
We recommend that you do not change this setting.

Boot Device Options

Boot SCSI ID—(Default: 0) Specifies the SCSI ID of your boot
device. We recommend that you do not change the default
setting.
Boot LUN Number—(Default: 0) Specifies which LUN (Logi-
cal Unit Number) to boot from on your boot device. This set-
ting is not valid unless Multiple LUN Support is Enabled (see
Advanced Configuration Options on page 21).

SCSI Device Configuration

SCSI Device Configuration options can be set individually for each
connected SCSI device.
Note:
To configure settings for a SCSI device, you must
know its SCSI ID (see Using SCSI Disk Utilities on page 23).
Sync Transfer Rate—(Default:
synchronous data transfer rate that the SCSI card supports.
Use the maximum value of 160 MBytes/sec. If a device is not
Ultra160, select the transfer rate of the device (80, 53, 40, ...).
