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.)

 

Emulation Type

 

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.

 

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

 

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 (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

 

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.

 

SATA Default Values

 

Allows you to specify the default values for the Multisector Transfers, Transfer Mode, and Translation

 

Mode for ATA devices.

 

 

Storage Options

Removable Media Boot

 

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

 

Legacy Diskette Write

 

Enables/disables ability to write data to legacy diskettes.
