Table 3 Computer Setup—Storage (continued)

When a device is selected, detailed information and options are displayed. The following options may be presented.

Diskette Type (Legacy Diskettes only)

Identifies the highest capacity media type accepted by the diskette drive. Options are 3.5" 1.44 MB and 5.25" 1.2 MB.

Drive Emulation

Allows you to select a drive emulation type for a certain storage device. (For example, a Zip drive can be made bootable by selecting diskette emulation.)

Drive Type Emulation Options

ATAPI Zip drive:

None (treated as Other).

Diskette (treated as diskette drive).

Legacy Diskette: No emulation options available.

CD-ROM: No emulation options available.

ATAPI LS-120:

None (treated as Other).

Diskette (treated as diskette drive). Hard Disk

None (prevents BIOS data accesses and disables it as a boot device).

Hard Disk (treated as hard disk).

Multisector Transfers (ATA disks only)

Specifies how many sectors are transferred per multi-sector PIO operation. Options (subject to device capabilities) are Disabled, 8, and 16.

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 (ATA 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 Automatic, Bit-Shift, LBA Assisted, User, and Off.

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(ATA disks only)

NOTE: This feature appears only when User translation mode is selected.

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
