& SATA Device Type
AllowsyoutoselectthetypeofthedeviceconnectedtotheSATAport.(Default:HardDiskDrive)
& 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
toxHCIorEHCIaccordingtosettingusedinpreviousboots(fornon-G3boot)inthe
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-
bootsupport.(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.
Manual Allows you to determine whether to rout the USB 3.0 ports to the xHCI or EHCI controller
before booting to OS, and also provides you with options to manually rout each USB
3.0/2.0 port to xHCI or EHCI.
& Audio Controller

If you wish to install a 3rd party add-in network card instead of using the onboard LAN, set this item to
Disabled.
