the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to
temporarily short the two pins or 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 clearing the CMOS values and before turning on your computer, be sure to remove the
jumper cap from the jumper. Failure to do so may cause damage to the motherboard.

• 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).

- 19 - Hardware Installation

15) 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.

Chapter 2 BIOS Setup

To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.
To see more advanced BIOS Setup menu options, you can press <Ctrl> + <F1> in the main menu of the
BIOS Setup program.
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/
clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)

Our Commitment to Preserving the Environment

In addition to high-efciency performance, all GIGABYTE motherboards fulll European Union regulations

for RoHS (Restriction of Certain Hazardous Substances in Electrical and Electronic Equipment) and WEEE
(Waste Electrical and Electronic Equipment) environmental directives, as well as most major worldwide safety
requirements. To prevent releases of harmful substances into the environment and to maximize the use of
our natural resources, GIGABYTE provides the following information on how you can responsibly recycle or
reuse most of the materials in your "end of life" product.

Restriction of Hazardous Substances (RoHS) Directive Statement

GIGABYTE products have not intended to add and safe from hazardous substances (Cd, Pb, Hg, Cr+6,
PBDE and PBB). The parts and components have been carefully selected to meet RoHS requirement. More­over, we at GIGABYTE are continuing our efforts to develop products that do not use internationally banned
toxic chemicals.

Waste Electrical & Electronic Equipment (WEEE) Directive Statement

GIGABYTE will fulll the national laws as interpreted from the 2002/96/EC WEEE (Waste Electrical and Elec­tronic Equipment) directive. The WEEE Directive species the treatment, collection, recycling and disposal of

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

WEEE Symbol Statement

The symbol shown below is on the product or on its packaging, which indicates that this product
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 ofce, your household waste disposal service or where you purchased

the product for details of environmentally safe recycling.

When your electrical or electronic equipment is no longer useful to you, "take it back" to your local or

w

regional waste collection administration for recycling.

If you need further assistance in recycling, reusing in your "end of life" product, you may contact us at the

w

Customer Care number listed in your product's user's manual and we will be glad to help you with your
effort.

Finally, we suggest that you practice other environmentally friendly actions by understanding and using the
energy-saving features of this product (where applicable), recycling the inner and outer packaging (including
shipping containers) this product was delivered in, and by disposing of or recycling used batteries properly.
With your help, we can reduce the amount of natural resources needed to produce electrical and electronic

equipment, minimize the use of landlls for the disposal of "end of life" products, and generally improve our

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