Serial ATA features such as Native Command Queuing and hot plug.

& xHCI Pre-Boot Driver

Enabled The USB 3.0 ports are routed to the xHCI controller before booting to OS. (Default)

Disabled The USB 3.0 ports are routed to the EHCI controller before booting to OS.

When this item is set to Enabled, the xHCI Mode below will be automatically set to Smart Auto; when this

item is set to Disabled, xHCI Mode will be automatically set to Auto.

& 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.
