Everything you need to boot this
motherboard is included in this
Easy Installation Guide. For more
information, a complete Online
User's Manual can be found in the
Bonus Pack CD. Thanks for the
help of saving our earth.

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 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
t
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.
