Description
Lists all installed BIOS-controlled storage devices.
When a device is selected, detailed information and options are displayed. The following options
might be presented:
Hard Drive: Size, model, firmware version, serial number, connector color.
●
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.
Available only when the drive translation mode is set to User, 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.
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.
CD-ROM: Model, firmware version, serial number, connector color (not included for USB CD-
●
ROM).
SSD Life Used
●
NOTE: Displays for solid-state drives.
SMART (ATA disks only)
●
Diskette: Model and firmware version.

See Translation Mode above for details.
SATA Defaults
eSATA Port
Allows you to set a SATA port as an eSATA port for use with an external drive. Default is enabled.
This setting affects only the port with the black connector, labeled as eSATA on the system board.
This port should have the eSATA back panel connector attached to use eSATA drives. For more
information, see the eSATA white paper at www.hp.com.
SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating
system. There are three supported options.
CAUTION: SATA emulation changes may prevent access to existing hard drive data and
degrade or corrupt established volumes.
IDE—Is the most backward-compatible setting of the three options. Operating systems usually do
not require additional driver support in IDE mode.
RAID (default option)—Allows DOS and boot access to RAID volumes. Use this mode with the
RAID device driver loaded in the operating system to take advantage of RAID features.
AHCI—Allows operating systems with AHCI device drivers loaded to take advantage of more
advanced features of the SATA controller.
