2-6 Peripherals
 &Initial Display Output
	 Specifies	the	first	 initiation	 of	the	 monitor	 display	from	the	installed	 PCI	graphics	 card,	PCI	Express	 graphics	
card or the onboard graphics.

 &XHCI Mode
 Allows you to determine the operating mode for the xHCI controller in OS.
 Smart Auto     This mode is available only when the BIOS supports the xHCI controller in the pre-boot 
environment. This mode is similar to Auto, but it adds the capability to route the ports 
to	xHCI	 or	EHCI	 according	 to	setting	 used	in	previous	 boots	(for	non-G3	 boot)	in	the	
pre-boot environment. This allows the use of USB 3.0 devices prior to OS boot. xHCI 
controller enabling and rerouting should follow the steps in Auto, when previous boot 
routs ports to EHCI. Note: This is the recommended mode when BIOS has xHCI pre-
boot	support.	(Default)
 Auto        BIOS routes the sharable ports to EHCI controller. Then it uses ACPI protocols to 
provide an option to enable the xHCI controller and reroute the sharable ports. Note: 
This is the recommended mode when BIOS does NOT have xHCI pre-boot support.
 Enabled      All shared ports are eventually routed to the xHCI controller during the\
 BIOS boot process. 
If BIOS does not have pre-boot support for the xHCI controller, it should initially route 
the sharable ports to the EHCI controller and then prior to OS boot it should route the 
ports to xHCI controller. Note: OS has to provide support for the xHCI controller in this 
mode. If the OS does not provide support, all sharable ports won't work.\
 Disabled      The USB 3.0 ports are routed to the EHCI controller and the xHCI controller is turned 
off. All USB 3.0 devices function as High Speed devices regardless of xHCI software 
support/availability.
