1. JP14 Clear CMOS

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

3. Troubleshooting…

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.

This motherboard comes with a 20-pin and 4-pin ATX power connector as shown below. Make sure you plug

in the right direction. We strongly recommend you to insert the 4-pin connector before connecting the 20-pin

connector.

1. Pull up the CPU socket lever and up to

90-degree angle.

2. Locate Pin 1 in the socket and look fo

a (golden) cut edge on the CPU uppe

interface. Match Pin 1 and cut edge.

Then insert the CPU into the socket.

3. Press down the CPU socket lever and

finish CPU installation.

Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan, you

can also plug it on FAN2 or FAN3 connector.

3. Installing Processor 5. Setting CPU Voltage & Frequency

This socket supports FC-PGA2 package CPU, which is the latest CPU package developed

by Intel. Other forms of CPU package are impossible to be fitted in.

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.

(Optional)

S/PDIF (Sony/Philips Digital Interface) is a latest audio transfer file format that provides

impressive quality through optical fiber and allows you to enjoy digital audio instead o

analog. 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 connecto

with a even better audio quality. Through a specific audio cable, you can connect the

S/PDIF connector to a S/PDIF audio module bearing S/PDIF digital output. However, you

must have a S/PDIF supported speaker with S/PDIF digital input to make the most of this

function.

6. Support Six USB2.0 Connectors

This motherboard provides six USB connectors to connect USB devices, such as mouse,

keyboard, modem, printer, etc. There are two connectors on the PC99 back panel. You

can use proper cable to connect other USB connectors to the back panel or front panel of

chassis.

The IrDA connector can be configured to support wireless infrared module, with this

module and application software such as Laplink or Windows 95 Direct Cable Connection,

user can transfer files to or from laptops, notebooks, PDA devices and printers. This

connector supports HPSIR (115.2Kbps, 2 meters) and ASK-IR (56Kbps).

Install the infrared module onto the IrDA connector and enable the infrared function from

BIOS Setup, UART Mode, make sure when you plug the IrDA connector in right

orientation.

This motherboard provides keyboard / mouse wake-up function. You can use JP28 to

enable or disable this function, which could resume your system from suspend mode with

keyboard or mouse. The factory default setting is set to “Disable”(1-2), and you ma

enable this function by setting the jumper to 2-3.

This motherboard comes with an Intel

10/100Mbps LAN controller embedded within ICH4.

You can find the LAN driver from the Bonus Pack CD.

If the housing has been designed with an audio port on the front panel, you’ll be able to

connect onboard audio to front panel through this connector. By the way, please remove

5-6 and 9-10 jumper caps from the Front Audio Connector before connecting the cable.

Please do not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on

the front panel.

You can install Intel VGA Driver to get the best graphics function of the chipset. You can find it in

the AOpen Bonus Pack CD.

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: WMX4L102.ZIP) with WinZip

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

3. Save the unzipped files into a folder, for example, WMX4L102.EXE &

WMX4L102.BIN.

4. Double click on the WMX4L102.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 star

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!

It is strongly recommended NOT to turn off the power or run any application during

FLASH PROCESS.
