Description
Lists all installed non-SCSI storage devices.
SCSI storage drives will not be listed in Computer Setup (F10).
When a device is selected, detailed information and options are displayed. The following
options might be presented:
Diskette Type (for legacy diskette drives only)
Identifies the highest capacity media type accepted by the diskette drive. Options are 3.5" 1.44
MB, 5.25" 1.2 MB, and Not Installed.
Drive Emulation (IDE devices only)
Allows you to select a drive emulation type for a storage device. (For example, a Zip drive can
be made bootable by selecting disk emulation.)
Drive Type Emulation Options
ATAPI Zip drive None (treated as Other).
Diskette (treated as diskette drive).
Disk (treated as hard drive).
IDE Hard disk None (treated as Other).
Disk (treated as hard drive).
Legacy diskette No emulation options available.
IDE CD-ROM No emulation options available.
ATAPI LS-120 No emulation options available.
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 (for example, SCO UNIX version 3.2). Options are Bit-Shift, LBA
Assisted, User, and None.
CAUTION: A new Automatic option has been added to allow for BIOS to automatically
determine the translation mode used to configure a previously formatted IDE, SATA, or USB
mass storage device. This prevents you from having to know how the mass storage device was
previously formatted.
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 cannot exceed 1024. The number of heads cannot
exceed 256. The number of sectors per track cannot 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.
