Translation Mode (IDE disks only)

(continued)

Configuration

Lets you select the translation mode to be used for the

 

(continued)

device. This enables the BIOS to access disks partitioned

 

 

and formatted on other systems and may be necessary for

 

 

users of older versions of Unix (e.g., SCO Unix version 3.2).

 

 

Options are Bit-Shift, LBA Assisted, User, and None.

 

 

CAUTION: Ordinarily, the translation mode

 

 

selected automatically by the BIOS should not

 

 

be changed. If the selected translation mode is

 

 

not compatible with the translation mode that

 

 

was active when the disk was partitioned and

 

 

formatted, the data on the disk will be

 

 

inaccessible.

 

 

Translation Parameters (IDE Disks only)

 

 

Allows you to specify the parameters (logical cylinders,

 

 

heads, and sectors per track) used by the BIOS to translate

 

 

disk I/O requests (from the operating system or an

 

 

application) into terms the hard drive can accept. Logical

 

 

cylinders may not exceed 1024. The number of heads may

 

 

not exceed 256. The number of sectors per track may not

 

 

exceed 63. These fields are only visible and changeable

 

 

when the drive translation mode is set to User.

 

 

Multisector Transfers (IDE ATA devices only)

 

 

Specifies how many sectors are transferred per multi-sector

 

 

PIO operation. Options (subject to device capabilities) are

 

 

Disabled, 8, and 16.

 

 

Quiet Drive (available on select drives only)

 

 

Performance - Allows the drive to operate at maximum

 

 

performance.

 

 

Quiet (will not be displayed if not supported by drive)-

 

 

Reduces noise from the drive during operation. When set to

 

 

Quiet, the drive will not operate at maximum performance.

 

Storage Options

Removable Media Boot

 

Enables/disables ability to boot the system from removable

 

 

 

 

media.

 

 

Note: After saving changes to Removable Media Boot, the

 

 

computer will restart. Turn the computer off, then on,

 

 

manually.

 

 

Removable Media Write

 

 

Enables/disables ability to write data to removable media.

 

 

Note: This feature applies only to legacy diskette, IDE LS-120

 

 

Superdisk, and IDE PD-CD drives.

 

 

Primary IDE Controller

 

 

Allows you to enable or disable the primary IDE controller.

 

 

Secondary IDE Controller

 

 

Allows you to enable or disable the secondary IDE controller.

 

 

Diskette MBR Validation

 

 

Allows you to enable or disable strict validation of the diskette

 

 

Master Boot Record (MBR).

 

 

Note: If you use a bootable diskette image that you know to

 

 

be valid, and it does not boot with Diskette MBR Validation

 

 

enabled, you may need to disable this option in order to use

 

 

the diskette.
