Chapter 2

BIOS Setup

BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows
the user to modify basic system configuration settings or to activate certain system features.
When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to
keep the configuration values in the CMOS.
To access the BIOS Setup program, press the & lt; Delete & gt; key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.
o Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating
system.
o @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet
and updates the BIOS.
o Because BIOS flashing is potentially risky, if you do not encounter problems using the current
version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with
caution. Inadequate BIOS flashing may result in system malfunction.
o It is recommended that you not alter the default settings (unless you need to) to prevent system
instability or other unexpected results. Inadequately altering the settings may result in system's
failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
(Refer to the " Load Optimized Defaults " section in this chapter or introductions of the battery/clear
CMOS jumper in Chapter 1 for how to clear the CMOS values.)

& xHCI Mode

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 preboot 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.
 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

we at GIGABYTE are continuing our efforts to develop products that do not use internationally banned toxic
chemicals.

and electronic devices and their components. Under the Directive, used equipment must be marked, collected
separately, and disposed of properly.

must not be disposed of with other waste. Instead, the device should be taken to the waste collection
centers for activation of the treatment, collection, recycling and disposal procedure. The separate
collection and recycling of your waste equipment at the time of disposal will help to conserve natural
resources and ensure that it is recycled in a manner that protects human health and the environment.
For more information about where you can drop off your waste equipment for recycling, please contact your
local government office, your household waste disposal service or where you purchased the product for details

quality of life by ensuring that potentially hazardous substances are not released into the environment and are
disposed of properly.
