Configuration

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 None.
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 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 disks only)
Specifies how many sectors are transferred per multi-sector PIO
operation. Options (subject to device capabilities) are Disabled,
8, and 16.
Options Removable Media Boot
Enables/disables ability to boot the system from removable media.
Removable Media Write

NOTE: This feature applies only to legacy diskette, (IDE/ATA) LS-120
Superdisk, (IDE/ATA) LS-240 Superdisk, and (IDE/ATA) PD-optical
drives.
NOTE: After saving changes to Removable Media Boot, the
workstation will restart. Manually, turn the workstation off, then on.
