v SCSI parity checking - This option determines whether the adapter verifies
the accuracy of data transfer on the SCSI bus. The initial setting is Enabled.
– Leave it set to Enabled. Most SCSI devices support SCSI parity.
– Select Disable if any device connected to the SCSI adapter does not
support SCSI parity. If you are not sure whether a device supports SCSI
parity, see the documentation that comes with the device.
v SCSI adapter SCSI termination - This option sets termination on the SCSI
adapter. The initial setting is Automatic. This setting is appropriate for most
situations. If you want to manually set the termination setting, refer to the
following table for the appropriate low and high settings. (The low byte
controls 8-bit SCSI; the low and high bytes together control 16-bit, Wide
SCSI.)

Boot-device settings
These settings enable you to specify the startup device.
v Boot target ID - This option specifies the SCSI ID of the device from which
to start up. The initial setting is SCSI ID 0. The SCSI ID selected must
correspond to the SCSI ID configured on the startup device.
v Boot LUN number - If your startup device has multiple Logical Unit
Numbers (LUNS) and multiple LUN support enabled, this option allows
you to specify which LUN to start up from on your startup device. The
initial setting is LUN 0. (You can set the multiple LUN support in the
"Advanced SCSI adapter settings" on page B-4.)
