Storage Options
DPS Self-Test
Boot Order
ENWW
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.
Default Values SATA
Allows you to specify the default values for the Multisector Transfers, Transfer Mode, and
Translation Mode for ATA devices.
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.
SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating system.
There are up to three supported options: Legacy Mode IDE, Native Mode IDE, and AHCI RAID.
Native Mode IDE is the default option. Use this option for "normal" (non-RAID) configurations.
Legacy Mode IDE is available for compatibility with older operating systems and software that only
comprehend legacy IDE resources.
Select the AHCI RAID option to enable DOS and boot accesses to RAID volumes. Use this option
for RAID configurations under Windows 2000, XP, or Vista with the appropriate RAID device driver.
NOTE: The RAID device driver must be installed prior to attempting to boot from a RAID volume.
If you attempt to boot from a RAID volume without the required device driver installed, the system
will crash (blue screen). Also, do not select the RAID option while the DriveLock feature is enabled
on any attached hard drives. Doing so will cause the DriveLocked drives to remain locked and
inaccessible during subsequent reboots until another SATA Emulation mode is selected.
For more information on RAID, go to http://www.hp.com/support. Select your country and language,
select See support and troubleshooting information, enter the model number of the computer,
and press Enter. In the Resources category, click Manuals (guides, supplements, addendums,
etc). Under Quick jump to manuals by category, click White papers.
Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection
System (DPS) self-tests.
NOTE: This selection will only appear when at least one drive capable of performing the DPS
self-tests is attached to the system.
Allows you to:
● Specify the order in which attached devices (such as a USB flash media device, diskette drive,
hard drive, optical drive, or network interface card) are checked for a bootable operating
system image. Each device on the list may be individually excluded from or included for
consideration as a bootable operating system source.
● Specify the order of attached hard drives. The first hard drive in the order will have priority in
the boot sequence and will be recognized as drive C (if any devices are attached).
NOTE: MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating
system has started.
Shortcut to Temporarily Override Boot Order
To boot one time from a device other than the default device specified in Boot Order, restart the
computer and press F9 when the monitor light turns green. After POST is completed, a list of
