2-6 Peripherals && Init Display First Specifies the first initiation of the monitor display from the onboard graphics or the installed PCI Express graphics card. IGFX Sets the onboard graphics as the first display. (Default) PCIe 1 Slot Sets the graphics card on the PCIEX16_1 slot as the first display. PCIe 2 Slot Sets the graphics card on the PCIEX8_1 slot as the first display. PCIe 3 Slot Sets the graphics card on the PCIEX16_2 slot as the first display. PCIe 4 Slot Sets the graphics card on the PCIEX8_2 slot as the first display. && PCH LAN Controller (Intel® GbE LAN Chip, LAN2) Enables or disables the Intel® GbE LAN function. (Default: Enabled) If you wish to install a 3rd party add-in network card instead of using the onboard LAN, set this item to Disabled. && XHCI Mode (Intel® Z87 Chipset) 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.
