Computer Setup-Storage Option Device Configuration Storage Options DPS Self-test Boot Order Description Lists all installed BIOS-controlled storage devices. When a device is selected, detailed information and options are displayed. The following options may be presented: Hard Disk: Size, model, firmware version, serial number. SATA Emulation CAUTION: SATA emulation changes may prevent access to existing drive data and degrade or corrupt established volumes. Allows you to choose how the SATA controller and devices are accessed by the operating system. There are two supported options: IDE and AHCI (default). IDE - This is the most backwards-compatible setting of the three options. Operating systems usually do not require additional driver support in IDE mode. AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take advantage of more advanced features of the SATA controller. USB Storage Boot Allows you to set USB storage device default boot option in CSM/Legacy mode. Secure Erase Allows you to use the software utility to issue a Secure Erase ATA instruction to a target storage device during the next boot. 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 EFI boot sources (such as a internal drive, USB hard drive, or USB optical drive) 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. EFI boot sources always have precedence over legacy boot sources. ● Specify the order in which legacy boot sources (such as a network interface card, internal drive, or USB optical drive) 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: You can use F5 to disable individual boot items, as well as disable EFI boot and/or legacy boot. 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 esc (to access the boot menu) and then F9 (Boot Order), or only F9 (skipping the boot menu) 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. 26 Chapter 2 Troubleshooting

Computer Setup—Storage
Option
Description
Device Configuration
Lists all installed BIOS-controlled storage devices. When a device is selected, detailed information and
options are displayed. The following options may be presented:
Hard Disk
: Size, model, firmware version, serial number.
Storage Options
SATA Emulation
CAUTION:
SATA emulation changes may prevent access to existing drive data and degrade or corrupt
established volumes.
Allows you to choose how the SATA controller and devices are accessed by the operating system. There
are two supported options: IDE and AHCI (default).
IDE - This is the most backwards-compatible setting of the three options. Operating systems usually do
not require additional driver support in IDE mode.
AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take advantage of
more advanced features of the SATA controller.
USB Storage Boot
Allows you to set USB storage device default boot option in CSM/Legacy mode.
Secure Erase
Allows you to use the software utility to issue a Secure Erase ATA instruction to a target storage device
during the next boot.
DPS Self-test
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.
Boot Order
Allows you to:
●
Specify the order in which EFI boot sources (such as a internal drive, USB hard drive, or USB optical
drive) 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. EFI boot sources
always have precedence over legacy boot sources.
●
Specify the order in which legacy boot sources (such as a network interface card, internal drive, or
USB optical drive) 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:
You can use
F5
to disable individual boot items, as well as disable EFI boot and/or legacy boot.
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
esc
(to access the boot menu) and then
F9
(Boot Order), or only
F9
(skipping the boot menu)
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.
