1. Clear CMOS Jumper: CLR_CMOS
Accessory Checklist
This motherboard uses the CMOS RAM to store all the parameters.The CMOS
can be cleared by resetting the CMOS jumper.
How to clear CMOS?
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 (pin 2 and 3 together with the jumper cap).
3. Turn the AC power supply back on.

The motherboard BIOS is inside the FWH. If the jumper BIOS_WP set as Close,
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 motherboard uses JP3, JP4, JP5 jumper to select USB power. JP3 is for USB,
JP4 is for NIC_USB, JP5 is for Front USB (F_USB1). Pin 1 and 2 together (default)
select +5V_SYS power, which not supports USB device wake up function. Pin 2
and 3 together select +5V_SB, which supports USB device wake up function.

The audio interface provides two kinds of audio output choices: the Front Audio,
the Rear Audio. Their priority is sequency from high to low(Front Audio to Rear
Audio). If headphones are plugged into the front panel of the chassis(using the
FrontAudio), then the Line-out (the RearAudio) on the rear panel will not work. If
you do not want to use the Front Audio, pin 5 and pin 6, pin 9 and pin 10 must be
SHORT, and then the signal will be sent to the rear audio port.

12. 5.1 Channel Audio Effects
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. Connect
the front speaker to the green audio output; connect the surround sound speaker
to the blue audio input; connect the center speaker/subwoofer to the red Micro-
phone input.
