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.
•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).
Open: Normal
Short: Clear CMOS Values
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.
13) CI (Chassis Intrusion Header)
This motherboard provides a chassis detection feature that detects if the chassis cover has been removed.
This function requires a chassis with chassis intrusion detection design.

Chapter 2 BIOS Setup
2-1 Startup Screen
The following startup Logo screen will appear when the computer boots.
(Sample BIOS Version: D3)
Function Keys
•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.
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.)
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.
