Device Properties Fields and Descriptions (Cont.)

 

 

 

 

Field

 

Field Type

Description

 

 

[Value]

 

 

 

 

 

Disconnect

 

Configuration

Indicates whether to allow a device to disconnect during

 

 

[On / Off]

SCSI operations. Some (usually newer) devices run

 

 

 

faster with disconnect enabled, while some (usually

 

 

 

older) devices run faster with disconnect disabled.

 

 

 

SCSI Time-out

Executable

Indicates the maximum allowable time for completion of

 

 

[0–9999]

a SCSI operation in seconds.

 

 

 

Since time-outs provide a safeguard that allows the

 

 

 

system to recover should an operation fail, it is

 

 

 

recommended that a value greater than zero be used. A

 

 

 

value of zero allows unlimited time for an operation to

 

 

 

complete and could result in the system hanging (waiting

 

 

 

forever) should an operation fail.

 

 

 

Note: This field is executable and must be selected with

 

 

 

the Enter key. You also input the new value with the

 

 

 

number keys from the keyboard, not the number pad.

 

 

 

 

Queue Tags

 

Configuration

This field indicates whether to allow the use of queue

 

 

[On / Off]

tags for a device. Currently the BIOS does not use

 

 

 

queue tags. This item specifies queue tag control to

 

 

 

higher level device drivers.

 

 

 

 

Boot Choice

 

Configuration

Indicates whether this device can be selected as the

 

 

[Yes / No]

boot device. This option is only applicable to devices

 

 

 

attached to adapter number zero in the boot list on

 

 

 

non-BBS systems. It provides primitive BBS flexibility to

 

 

 

non-BBS systems.

 

 

 

 

Format

 

Executable

Allows low-level formatting on a disk drive, if enabled.

 

 

 

Low-level formatting will completely and irreversibly

 

 

 

erase all data on the drive. To low level format a device,

 

 

 

select the device from the menu and use the arrow keys

 

 

 

to move the cursor to the Format column. Press Enter.

 

 

 

Note: Formatting will default the drive to a 512-byte

 

 

 

sector size even if the drive had previously been

 

 

 

formatted to another sector size.

 

 

 

 

Verify

 

Executable

Allows verification of all sectors on a device and

 

 

 

reassigns defective Logical Block Addresses, if enabled.

 

 

 

To verify all sectors, select the device from the menu and

 

 

 

use the arrow keys to move the cursor to the Verify

 

 

 

column. Press Enter.

 

 

 

<Restore Defaults>

Executable

Press Enter to obtain default settings.
