Table 2-3Computer Setup—Storage (continued)

Storage Options

SATA Emulation

 

Allows you to choose how the SATA controller and devices are accessed by the operating system.

 

There are three supported options: IDE, RAID, 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.

 

NOTE: The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/

 

AHCI volume. If you attempt to boot from a RAID/AHCI volume without the required device driver

 

installed, the system will crash (blue screen). RAID volumes may become corrupted if they are

 

booted to after disabling RAID.

 

NOTE: RAID is not available on USDT systems.

 

 

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 selftests

 

is attached to the system.

 

 

Boot Order

Allows you to:

 

 

● Specify the order in which EFI boot sources (such as a internal hard drive, USB hard drive,

 

USB optical drive, or internal 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

 

hard drive, USB optical drive, or internal 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.

 

NOTE: MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating system

 

has started.
