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. Since this provides a safeguard allowing the system to recover if an I/O operation fails, it is recommended that you always set the time-out to a value greater than zero.

Note: If the time-out is set to zero, then the I/O will never time-out.

Scan for Device at Boot Time – Set this option to No when there is a device 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 you have problems with a device that responds to all LUNs whether they are occupied or not. For example, if there is a SCSI device with multiple LUNs 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 – This option allows the user to enable or disable the issuing of queue tags during I/O requests when your device driver can do this.

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 some of the flexibility of a BBS machine.

Format – If enabled, this option allows you to low-level format a magnetic disk drive. Low-level formatting will completely and irreversibly erase all data on the drive. Note that this utility will only format 512 byte sectors. For other sector sizes, do not use this utility.

Verify – This option allows you 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

Help – This option displays a help screen with information about the current menu.
