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)
BIOS routes the sharable ports to EHCI controller. Then it uses ACPI protocols to
Auto
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.
