Set the USB 3.0 controller mode
for the ports shared between
USB 2.0 and USB 3.0 controller.
If you select Auto, it enables you
to connect and route appropriate
USB 3.0 or USB 2.0 connectors.
If you select Enabled, it enables
the USB 3.0 mode and allows
the USB 3.0 to be supported
in the Windows 7 operating
system.
If you select Disabled, it disables
and hides the USB 3.0 controller,
and the USB 3.0 connectors will
work as USB 2.0 connectors.
If you select Enabled, the Fn key
works as the Ctrl key, and the
Ctrl key works as the Fn key.
Note: Even when Enabled is
selected, you need to press the
Fn key to resume the computer
from sleep mode to normal
operation.
Select the display device to be
activated at boot time. This

time, password prompt, and

The Integrated Graphics mode
provides longer battery life. The
Switchable Graphics mode runs
as Integrated Graphics mode
and Discrete Graphics is enabled
on demand.
Note: Switchable Graphics
mode should only be selected
if you are using the Windows 7
operating system.
If you select Enabled, the
system UEFI BIOS automatically
switches the Graphics Device
setting to Switchable Graphics
mode if the operating system
supports this feature, and to
Integrated Graphics mode if
the operating system does not
support this feature.
