2-6 Peripherals
& Init Display First
Specifes the frst initiation of the monitor display from the installed PCI graphics card, PCI Express graphics
card, or the onboard graphics.
IGFX Sets the onboard graphics as the rst display.
PCIe 1 Slot Sets the graphics card on the PCIEX16 slot as the rst display.(Default)
PCIe 2 Slot Sets the graphics card on the PCIEX4_1 slot as the rst display.
PCIe 3 Slot Sets the graphics card on the PCIEX8 slot as the rst display.
PCIe 4 Slot Sets the graphics card on the PCIEX4_2 slot as the rst display.
PCI Sets the graphics card on the PCI as the rst display.
& PCH LAN Controller
Enables or disables the onboard 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 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.
