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).

 

CAUTION: SATA emulation changes may prevent access to existing hard drive data and

 

degrade or corrupt established volumes.

 

IDE - This is the most backwards-compatible setting of the three options. Operating systems usually

 

do not require additional driver support in IDE mode.

 

RAID - 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 (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.

 

Removable Media Boot

 

Enables/disables ability to boot the system from removable media. Default is enabled.

 

 

Boot Order

Allows you to:

 

● EFI Boot Sources: 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.

 

● 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: To drag a device to a preferred place, press Enter. To remove the device from

 

consideration as a bootable device, press F5.

 

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.

 

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.
