ATAPI LS-120

None (treated as Other).

 

 

 

 

 

 

 

 

 

 

Diskette (treated as diskette drive).

 

 

 

 

 

 

 

 

Transfer Mode (IDE devices only)

 

 

 

Specifies the active data transfer mode. Options (subject to

 

 

 

device capabilities) are PIO 0, Max PIO, Enhanced DMA,

 

 

 

Ultra DMA 0, and Max UDMA.

 

 

 

 

 

 

 

 

Translation Mode (IDE disks only)

 

 

 

Lets you select the translation mode to be used for the 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 Off.

 

 

 

Ä 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 1023. The number of heads may not exceed 255. 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 disks only)

 

 

 

Specifies how many sectors are transferred per multi-sector PIO

 

 

 

operation. Options (subject to device capabilities) are Disable,

 

 

 

8, and 16.

 

 

 

 

 

 

 

 

 

Options

Removable Media Boot

Enables/disables ability to boot the system from removable media.

Removable Media Write

Enables/disables ability to write data to removable media.

✎ This feature applies only to legacy diskette, (IDE/ATA) LS-120 Superdisk, (IDE/ATA) LS-240 Superdisk, and (IDE/ATA) PD-optical drives.

✎ After saving changes to Removable Media Boot, the computer will restart. Manually, turn the computer off, then on.

*Option supported on select models.
