You can clear CMOS to restore default system setting. To clear the CMOS, follow
the procedures described below.
1. Turn off the AC power supply and connect pin 1 and 2 together using the jumper
cap .
2. Return the jumper setting to normal (pin2 and 3 together with the jumper cap).
3. Turn the AC power supply back on.
If the jumper FWH_EN set as “Disable” (pin2 & pin3), the system BIOS is protected
from being attacked by a serious virus, such as the CIH virus. You will be unable to
flash the BIOS to the motherboard when the system BIOS is protected.

The connector supports wireless transmitting and receiving device. Before using
this function, configure the settings of IR Mode from the “Integrated Peripherals”
section of the CMOS Setup.
The USB header is available for additional USB port if the USB ports on the rear
panel are inadequate. Compared to traditional USB 1.1 with the speed of 12Mbps,
USB 2.0 has a fancy speed up to 480Mbps, which allows faster Internet connection,
interactive gaming, and simutaneous running of high-speed peripherals.

CD_IN is Sony standard CD audio connector, it can be connected to a CD-ROM
drive through a CD audio cable.
The audio interface provides two kinds of audio output choices: the Front Audio,
the Rear Audio. Their priority is sequenced from high to low (Front Audio to Rear
Audio). If headphones are plugged into the front panel of the chassis (using the
Front Audio), then the Line-out (Rear Audio) on the rear panel will not work. If you
do not want to use the Front Audio, pin 5 and 6, pin 9 and 10 must be SHORT, and
then the signal will be sent to the rear audio port.

After you finish the setting of jumpers and connect correct cables, power on the
system and press <Del> during POST (Power On Self Test) to enter the BIOS Setup
Utility. Choose “Load Optimized Defaults” for recommended optimal performance.
Please make sure your system components are good enough for optimized defaults.
The motherboard is equipped with the Realtek ALC655 chip, which provides sup-
port for 6-channel audio output, including 2 front, 2 rear, 1 center and 1 subwoofer
channel. ALC655 allows the board to attach 4 or 6 speakers for a better surround
sound effect. To apply this function, you have to install the audio driver in utility CD
as well as an audio application supporting 5.1 Channel. Picture bellow repre-
sents the standard location of all speakers in 5.1 Channel sound track.
