Read Write I/O Time-out (seconds) – This option sets the amount of
time the host adapter waits for a read, write, or seek command to
complete before trying the I/O transfer again. Because this provides a
safeguard by allowing the system to recover if an I/O operation fails, you
should always set the time-out to a value greater than zero.
Note:
A zero value allows unlimited time for an operation to
complete and could result in the system being hung-up.
Scan for Device at Boot Time – Set this option to
no
if there is a
device that you do not want to be available to the system. Also, on a bus
with only a few devices attached, you can speed up boot time by
changing this setting to
no
for all unused SCSI IDs.
Scan for SCSI Logical Units (LUNs) – Set this option to
no
if problems
arise with a device that responds to all LUNs whether they are occupied
or not. For example, if a SCSI device with multiple LUNs is present on
the system but you do not want all of those LUNs to be available to the
system, then set this option to
no
. This will limit the scan to LUN 0 only.
Queue Tags – If the device driver has the capability, this option allows
the user to enable or disable the issuing of queue tags during I/O
requests.
Initial Boot – This option allows any device attached to the first adapter
to become the boot device. It provides the users of non-BBS personal
computers with some of the flexibility of a BBS machine.
Format Device – If enabled, this option allows the user to low-level
format a magnetic disk drive. Low-level formatting will completely and
irreversibly erase all data on the drive. Formatting will default the drive to
a 512-byte sector size even if the drive had previously been formatted to
another sector size.
Verify – This option allows the user to read all the sectors on a disk
looking for errors. When selected, this option displays the following
message:
“Verify all sectors on the device
Press ESC to abort
Else press any key to continue”
