[. . . ] (Default) PCIe 2 Slot  Sets the graphics card on the PCIEX8 slot as the first display. PCI  Sets the graphics card on the PCI slot as the first display. 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 preboot 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  USB 3. 0 ports are routed to the EHCI controller and the xHCI controller is turned  The off. All USB 3. 0 devices function as High Speed devices regardless of xHCI software support/availability. - 50 - && XHCI Mode (Intel® Z87 Chipset) BIOS Setup 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 Enables or disables the onboard audio function. (Default: Auto) If you wish to install a 3rd party add-in audio card instead of using the onboard audio, set this item to Disabled. Enables or disables the onboard audio LED. (Default: Enabled) && Audio LED && USB DAC Power Enables or disables the power for the USB DAC connector on the back panel. For a USB DAC that has independent power, set this item to Disabled.
