Host Adapter SCSI ID. This option sets the host
adapter's SCSI ID. The default setting is SCSI ID 7,
which allows the host adapter to support narrow
SCSI devices in addition to wide SCSI devices. Dell
recommends that you leave the host adapter set to
SCSI ID 7.
SCSI Parity Checking. This option determines
whether the host adapter verifies the accuracy of data
transfer on the SCSI bus. The default setting is
Enabled. You should disable SCSI Parity Checking
if any SCSI device connected to the host adapter
does not support SCSI parity; otherwise, leave it
enabled. Most SCSI devices support SCSI parity. If
you are unsure if a device supports SCSI parity, con-
sult the documentation for the device.
Host Adapter SCSI Termination. This option sets ter-
mination on the host adapter. The default setting for
all Adaptec 78xx series host adapters is Low On/
High On. Dell recommends that you leave this
option set to the default.
Boot Target ID. This option specifies the SCSI ID of
the device from which you wish to boot your system.
The default setting is SCSI ID 0. The SCSI ID
selected here must correspond to the ID configured
on the boot device.
Boot LUN Number. If your boot device has multiple
logical unit numbers (LUNs) and Multiple LUN
Support is enabled (see "Advanced Host Adapter
Settings" found later in this section), this option
allows you to specify a particular LUN from which
to boot on your boot device. The default setting is
LUN 0.
