Disabled.
& 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.
