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 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.
BIOS Setup  
						

							- 55 -
 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      The USB 3.0 ports are routed to the EHCI controller and the xHCI controller is turned 
off. All USB 3.0 devices function as High Speed devices regardless of xHCI software 
support/availability.
 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 th\
e onboard audio, set this item to 
Disabled.
