Option Description
Boot Mode
(BIOS default)
CAUTION: Switching the boot mode could prevent
the system from booting if the operating system was
not installed in the same boot mode.
If the operating system supports UEFI, you can set this
option to UEFI. Setting this field to BIOS allows
compatibility with non-UEFI operating systems.
NOTE: Setting this field to UEFI disables the Boot
Sequence, Hard-Disk Drive Sequence, and USB Flash Drive
Emulation Type fields.
Boot Sequence If Boot Mode is set to BIOS, this field indicates to the
system the location of the operating system files needed
for startup. If Boot Mode is set to UEFI, you can access
the UEFI boot manager utility by rebooting the system
and pressing F11 when prompted to do so.
Hard-Disk Drive
Sequence
Determines the order in which the BIOS attempts to
boot from hard drives in the system during system
startup.
USB Flash Drive
Emulation Type
(Auto default)
Determines the emulation type for a USB flash drive.
Hard disk allows the USB flash drive to act as a hard
drive. Floppy allows the USB flash drive to act as a
removable diskette drive. Auto automatically chooses an
emulation type.
Boot Sequence Retry
(Disabled default)
If this field is enabled and the system has failed to boot,
the system reattempts to boot after 30 seconds.
