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.
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.
