BIOS ROM

Storage

(continued)

IDE Controller

Allows you to enable or disable the primary IDE controller. This

feature is supported on select models only.

Primary SATA Controller

Allows you to enable or disable the Primary SATA controller.

Secondary SATA Controller

Allows you to enable or disable the Secondary SATA controller. This

feature is supported on select models only.

DPS Self-Test

Allows you to execute self-tests on ATA hard drives capable of

performing the Drive Protection System (DPS) self-tests.

✎

This selection will only appear when at least one drive capable of

performing the DPS self-tests is attached to the system.

Boot Order

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).

✎

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

when the

monitor light turns green. After POST is completed, a list of bootable

devices is displayed. Use the arrow keys to select the preferred

bootable device and press

Enter

. The computer then boots from the

selected non-default device for this one time.
