Enabled: All shared ports are eventually routed to the xHCI control-
ler 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 sup-
port, all sharable ports will not 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/ avail-
ability.
Legacy USB Support
Set to [Enabled] if you need to use any USB 1.1/2.0 device in the
operating system that does not support or have any USB 1.1/2.0 driver
installed, such as DOS and SCO Unix.
Audio Controller
This setting enables/disables the onboard audio controller.
Launch OnChip Lan OpROM/ Launch OnBoard Lan OpROM
These settings enable/disable the initialization of the onchip/ onboard
PXE Boot ROM during bootup. Selecting [Disabled] will speed up the
boot process.
CPU Configuration

This setting allows user to select the number of cores to enable in each
processor package. Note that this field is present only when a multi-
core processor is installed.
