Clear CMOS Jumper: CLS_CMOS 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. Clear CMOS 1 Normal (Default) 1 CLS_CMOS 3. BIOS-Protection Jumper (optional): FWH_EN 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. 1 Flash write Disable 1 Flash Write Enable (Default) FWH_EN 4 4.

IrDA Header (optional): IR 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. +5V Empty IRRX GND IRTX 1 IR 7. USB Header: F_USB1 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. 1 VCC D0D0+ GND Empty 9 2 VCC D1D1+ GND NC 10 F_USB1 6 8. CD_IN Connector: CD_IN CD_IN is Sony standard CD audio connector, it can be connected to a CD-ROM drive through a CD audio cable. CD_L GND CD_R 1 CD_IN 9. Front Audio Connector: F_AUDIO 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. 1 MIC_IN MIC_PWR AUD_OUT_R NC AUD_OUT_L 9 2 MIC_GND +5VA AUD_RET_R Empty AUD_RET_L 10 F_ AUDIO 7 10.

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 represents the standard location of all speakers in 5.1 Channel sound track. Blue Green Center Red Rear Left Front Left Front Right Rear Right Subwoofer 13. Power on and Load Optimized Defaults After you finish the setting of jumpers and connect correct cables, power on the system and press 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. Select this option and press . 9 14.
