When you read this online manual and start to assemble your computer system, you may find some of functions are called
“Manufacturer Upgrade Optional”, and some are called “User Upgrade Optional”. Though all AOpen motherboards include many
amazing and powerful features, in some situations, these powerful features are not used to every user. Hence, we changed
some key features as “Manufacturer Upgrade Optional” for you to c hoose. Some optional functions that can be upgraded by
users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them
“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade

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 pins 1 & pin2.
5. Connect ATX power cable back to connector PWR2.

fiber and allows you to enjoy digital audio instead of analog audio. Normally there are two S/PDIF outputs as shown, one for

quality. Through a specific audio cable, you can connect the S/PDIF connector to othe

into the special-designed purple slot as you can see, which we call ADD slot here. The function of these two DVO ports is to
support a variety of digital display devices, such as LCDs and Digital-input CRT, and is possible to use in dual-channel mode to
support higher resolution and refresh rate, while deliver digital signal from source to display to preserve signal integrity and the

This feature is very similar as Wake On Modem, but it goes through local area network. To use Wake On LAN function, you must
have a network card with chipset that supports this feature, and connect a cable from LAN card to motherboard WOL connector.
The system identification information (probably IP address) is stored on network card and because there is a lot of traffic on the
Ethernet, you need to install network management software, such as ADM, for the checking of how to wake up the system. Note
that, at least 600m A ATX standby current is required to support t he LAN c ard for t his f unc tion.

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,
new generation CPU is able to use regulator of different voltages to transfer 5V to CPU voltage (for example, to 2.0V). This
motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power
supply for providing full line over-c urrent prot ect ion.
Note: Although we have implemented protection circuit try to prevent any human operating
mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this
motherboard may be damaged because of component failure, human operating error or unknown
nature reason. AOpen cannot guaranty the protection circuit will always work perfectly.

just clicking on the utility you downloaded from web and let it helps you complete the flash process automatically. EzWinFlash
detects your motherboard and checks the BIOS version cleverly to prevent your system from any possible failure. Moreover,
EzWinFlash has been taken into consideration to go with any windows platform you might be using, no matter if you’re using
Windows 95/98, 98SE/ ME, NT4. 0/2000, or even the l ates t Windows XP.
In the meanwhile, in order to provide a much more user-friendly operating environment, AOpen EzWinFlash is natively designed
to have multi-language funct ion t o provide easi er way for users ’ usage in changing B IOS s ett ing.
Note: The model name on this B IOS pict ure is for ref erence onl y. It may not be the exact model nam e.
Caution: By updating your motherboard,
you are taking a risk of BIOS flash
failure. If your motherboard is working
stable, and there are no major bugs that
had been f ixed by a latt er BIOS rev ision,
we recommend that you DO NOT try to
upgrade your BIOS.
If you intent on upgrading, PLEASE BE
SURE to get the right BIOS revision for
the right motherboard model to avoid any
ossibility failure.

You may accomplish BIOS upgrade procedure with EzWinFlash by the following steps, and it’s STRONGLY RECOMMMANDED
to close all the applicat ions before you s tart t he 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: WAX4LN102.ZIP) with WinZip (http://www.winzip.com) in Windows
environment.
3. Save the unzipped files into a f older, for example, WAX4LN102.EXE & W AX4LN102.BI N.
4. Double click on the WAX4LN102.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 st eps.
5. You may select preferred language in the main menu, then c li ck [Start Flash] to s tart t he 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 B IOS set up, c hoose " Load Setup Def aults" , t hen “Save & Exit Set up”. Done!
It is strongly recommended NOT to turn off the power or run any application during FLASH PROCESS.
Warning: The new BIOS upgrade will
permanently replace your original
BIOS’s settings when flashing. You
may need to reconfigure your BIOS
setting so that your system can go
back to work as normal.
