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”
