You can clear CMOS to restore default system setting. To clear the CMOS, follow
the procedures described below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from PWR1 connector.
3. Short pins 1 and 2 on this jumper.
4. Return the jumper to the normal setting by locking pins 2 and 3 together with
the jumper cap.
5. Turn the system on. The BIOS is returned to the default settings.
2. CPU Model Selection Jumper: J2
J2 is OPEN at default, which supports the Prescott and Northwood CPU. If J2 is
set as SHORT, it supports the Willamette CPU.

4. Front Audio Connector
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.

The USB connector 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 simultaneous running of high-speed peripherals.

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.

Select this option
and press <Enter>.
11. 6-channel Audio Effects
The motherboard is equipped with the CODEC ALC655 chip, which provides supp-
ort 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 6-channel. The illustration shown below
represents the standard location of all speakers in 6-channel sound track. Connect
the front speaker to the green audio output; connect the surround sound speaker to
the blue audio output and connect the center speaker/subwoofer to the red microphone
output.
