14) BAT (Battery)

The battery provides power to keep the values (such as BIOS congurations, date, and time information)

in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low
level, or the CMOS values may not be accurate or may be lost.

You may clear the CMOS values by removing the battery:

1. Turn off your computer and unplug the power cord.

2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal
object like a screwdriver to touch the positive and negative terminals of the battery holder,
making them short for 5 seconds.)

3. Replace the battery.

4. Plug in the power cord and restart your computer.

• Always turn off your computer and unplug the power cord before replacing the battery.

• Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with an incorrect model.

• Contact the place of purchase or local dealer if you are not able to replace the battery by yourself or uncertain
about the battery model.

• When installing the battery, note the orientation of the positive side (+) and the negative side (-) of the battery
(the positive side should face up).

• Used batteries must be handled in accordance with local environmental regulations.

15) CLR_CMOS (Clear CMOS Jumper)

Use this jumper to clear the BIOS conguration and reset the CMOS values to factory defaults. To clear

the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.

Open: Normal

Short: Clear CMOS Values

• Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS values.

• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or manually

congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS congurations).

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 conguration 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 conguration values in the CMOS.

To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.

• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating system.

• @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet
and updates the BIOS.

• Because BIOS ashing is potentially risky, if you do not encounter problems using the current version of BIOS,

it is recommended that you not ash the BIOS. To ash the BIOS, do it with caution. Inadequate BIOS ashing

may result in system malfunction.

• 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.)

2-1 Startup Screen

The following startup Logo screen will appear when the computer boots.
(Sample BIOS Version: E9)

Function Keys

Differing from traditional UEFI interface, the Dashboard Mode provides a fancy and user-friendly BIOS
environment where users can easily point and click through various settings and make adjustments for optimum
performance. In Dashboard Mode, you can use your mouse to move through the option menus for quick
conguration or you can click Classic Setup under the Shortcuts list on the right of the screen or press <F2>
to switch to the traditional BIOS Setup screen. On the main menu of the BIOS Setup program, press arrow
keys to move among the items and press <Enter> to accept or enter a sub-menu. Or you can use your mouse
to select the item you want.

• When the system is not stable as usual, select the Load Optimized Defaults item to set your system to its defaults.

• The BIOS Setup menus described in this chapter are for reference only and may differ by BIOS version.

& 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 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
