Boot Settings Screen
Option	Description
Boot Mode	CAUTION: Switching the boot mode could prevent
(BIOS default)	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	Determines the order in which the BIOS attempts to
Sequence	boot from hard drives in the system during system
	startup.
USB Flash Drive	Determines the emulation type for a USB flash drive.
Emulation Type	Hard disk allows the USB flash drive to act as a hard
(Auto default)	drive. Floppy allows the USB flash drive to act as a
	removable diskette drive. Auto automatically chooses an
	emulation type.
Boot Sequence Retry	If this field is enabled and the system has failed to boot,
(Disabled default)	the system reattempts to boot after 30 seconds.
