You can clear CMOS to restore system default setting. To

clear the CMOS, follow the procedure below.

1. Turn off the system and unplug the AC power.

2. Remove ATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pin 1 & pin 2.

5. Connect ATX power cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides impressive

quality through optical fiber and allows you to enjoy digital audio instead of analog audio. Normally there are

two S/PDIF outputs as shown, one for RCA connector, the most common one used for consumer audio

products, and the other for optical connector with better audio quality. Through a specific audio cable, you

can connect the S/PDIF connector to other end of the S/PDIF audio module, which bears S/PDIF digital

output. However, you must have a S/PDIF supported speaker with S/PDIF digital input to connect to the

S/PDIF digital output to make the most out of this function. (Optional)

Setting CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be automaticall

detected.

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency through the

BIOS setup, and no jumpers or switches are needed. The default setting is "table selec

mode". You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.

You may accomplish BIOS upgrade procedure with EzWinFlash by the following steps,

and it’s STRONGLY RECOMMENDED to close all the applications before you start the

upgrading.

1. Download the new version of BIOS package zip file from AOpen official web site. (ex:

http://www.aopen.com)

2. Unzip the download BIOS package (ex: WMX4GR102.ZIP) with WinZip

(http://www.winzip.com) in Windows environment.

3. Save the unzipped files into a folder, for example, WMX4GR102.EXE &

WMX4GR102.BIN.

4. Double click on the WMX4GR102.EXE, EZWinFlash will detect the model name and

BIOS version of your motherboard. If you had got the wrong BIOS, you will not be

allowed to proceed with the flash steps.

5. You may select preferred language in the main menu, then click [Start Flash] to start

the BIOS upgrade procedure.

6. EzWinFlash will complete all the process automatically, and a dialogue box will pop

up to ask you to restart Windows. You may click [YES] to reboot Windows.

7. Press <Del> at POST to enter BIOS setup, choose "Load Setup Defaults", then

“Save & Exit Setup”. Done!

Warning: The upgrade of new BIOS will permanently replace your original BIOS

content after flashing. The original BIOS setting and Win95/Win98 PnP

information will be refreshed and you probably need to re-configure your system.

If you encounter any trouble to boot you system, follow the procedures

accordingly to resolve the problem.

Perhaps your VGA card or monito

is defective.

Yes

It is very possible that your keyboard

is defective.

During system rebooting, press Del to enter BIOS Setup. Choose

IDE cables or HDD itself.

Re-install Windows 95, Windows 98 or Windows NT.

Yes

Turn off the power and unplug the AC power cable, then remove all

of the addon cards and cables, including VGA, IDE, FDD, COM1,

COM2 and Printer.

Turn on the power, and check if

the power supply and CPU fan

work properly.

Start

Check if there is display.

Press Ctrl, and Alt key at the

same time, hold them and then

press Del to see if the

stem reboots.

Turn off the system and

re-connect the IDE cable.

Check if the system can

reboot successfully.
