SCSI Controller ID-(Default: 7) Sets the SCSI ID for the SCSI card. The Adaptec U320 SCSI RAID 0 or 1 is set at 7, which gives it the highest priority on the SCSI bus. We recommend that you do not change this setting. SCSI Controller Parity-(Default: Enabled) SCSI cards perform parity checking to verify the accuracy of data transfer on the SCSI bus. Most currently available SCSI devices support parity checking. However, if a device on the SCSI bus does not support parity checking, disable this option. This setting changes parity for the entire SCSI controller and the way it looks at each ID on that controller. You cannot mix devices that do and do not support parity checking on the same SCSI bus. SCSI Controller Termination-(Default: Automatic) Determines the termination setting for the SCSI card. The default setting is Automatic, which allows the SCSI card to adjust the termination as needed. We recommend that you do not change this setting. Boot Device Configuration Options - BBS Systems Only The BBS (BIOS Boot Specification) enables the BIOS to identify all IPL devices in the system, prioritize them in the order you select, and sequentially go through each device to allow booting. Select Master SCSI Controller-Enables you to select the master SCSI controller. The master SCSI card does not necessarily have to be the same as the boot SCSI controller. Boot SCSI Controller-Enables you to select which SCSI controller is the boot SCSI controller. The boot SCSI controller does not necessarily have to be the same as the master SCSI controller. Boot Device Configuration - Non-BBS Systems Only In a non-BBS system, it is the SCSI card BIOS, not the system BIOS, that controls the Select Master SCSI Controller, Boot SCSI ID, and Boot LUN Number settings. Select Master SCSI Controller-(Default: A First) Enables you to select the master SCSI controller. The master SCSI card does not necessarily have to be the same as the boot SCSI controller. If you change this setting, the change automatically applies to both SCSI channels. Boot SCSI Controller-Enables you to select which SCSI controller is the boot SCSI controller. The boot SCSI controller does not necessarily have to be the same as the master SCSI controller. If you change this setting, the change automatically applies to both SCSI channels. Boot SCSI ID-(Default: 0) Specifies the SCSI ID of your boot device. We recommend that you do not change the default setting. If you change this setting, the change automatically applies to both SCSI channels. Boot LUN Number-(Default: 0) Specifies which LUN (Logical Unit Number) to boot from on your boot device. This setting is not valid unless Multiple LUN Support is enabled (see "Advanced Configuration Options"). If you change this setting, the change automatically applies to both SCSI channels. SCSI Device Configuration Options 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". Sync Transfer Rate (MB/sec)-(Default: see following table) The BIOS may negotiate for a transfer rate between controller and device of up to 80 MB/sec for Wide transfers and 40 MB/sec for Narrow transfers.

SCSI Controller ID
—(Default: 7) Sets the SCSI ID for the SCSI card. The Adaptec U320 SCSI RAID 0 or 1 is
set at 7, which gives it the highest priority on the SCSI bus. We recommend that you do not change this setting.
SCSI Controller Parity
—(Default: Enabled) SCSI cards perform parity checking to verify the accuracy of data
transfer on the SCSI bus. Most currently available SCSI devices support parity checking. However, if a device on
the SCSI bus does not support parity checking, disable this option. This setting changes parity for the entire
SCSI controller and the way it looks at each ID on that controller. You cannot mix devices that do and do not
support parity checking on the same SCSI bus.
SCSI Controller Termination
—(Default: Automatic) Determines the termination setting for the SCSI card. The
default setting is Automatic, which allows the SCSI card to adjust the termination as needed. We recommend
that you do not change this setting.
Boot Device Configuration Options – BBS Systems Only
The BBS (BIOS Boot Specification) enables the BIOS to identify all IPL devices in the system, prioritize them in the
order you select, and sequentially go through each device to allow booting.
Select Master SCSI Controller
—Enables you to select the master SCSI controller. The master SCSI card does
not necessarily have to be the same as the boot SCSI controller.
Boot SCSI Controller
—Enables you to select which SCSI controller is the boot SCSI controller. The boot SCSI
controller does not necessarily have to be the same as the master SCSI controller.
Boot Device Configuration – Non-BBS Systems Only
In a non-BBS system, it is the SCSI card BIOS, not the system BIOS, that controls the Select Master SCSI Controller,
Boot SCSI ID, and Boot LUN Number settings.
Select Master SCSI Controller
—(Default: A First) Enables you to select the master SCSI controller. The
master SCSI card does not necessarily have to be the same as the boot SCSI controller. If you change this
setting, the change automatically applies to both SCSI channels.
Boot SCSI Controller
—Enables you to select which SCSI controller is the boot SCSI controller. The boot SCSI
controller does not necessarily have to be the same as the master SCSI controller. If you change this setting, the
change automatically applies to both SCSI channels.
Boot SCSI ID
—(Default: 0) Specifies the SCSI ID of your boot device. We recommend that you do not change
the default setting. If you change this setting, the change automatically applies to both SCSI channels.
Boot LUN Number
—(Default: 0) Specifies which LUN (Logical Unit Number) to boot from on your boot
device. This setting is not valid unless Multiple LUN Support is enabled (see "
Advanced Configuration
Options
"). If you change this setting, the change automatically applies to both SCSI channels.
SCSI Device Configuration Options
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
".
Sync Transfer Rate (MB/sec)
—(Default: see following table) The BIOS may negotiate for a transfer rate
between controller and device of up to 80 MB/sec for Wide transfers and 40 MB/sec for Narrow transfers. The
