5. Setting CPU Voltage & Frequency

Setting CPU Core Voltage

The CPU core voltage will be automatically detected. It is not necessary to set CPU core

voltage.

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.

BIOS Setup > Frequency / Voltage Control > CPU Speed Setting

Core Frequency = CPU FSB Clock * CPU Ratio

3. Installing Processor

Note: If you do not match the CPU

socket Pin 1 and CPU cut edge well, it

may damage the CPU.

4. Installing CPU & System Fan

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

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

Note: Some CPU fans do not

have sensor pin so they cannot

support fan monitoring.

7. Connect IrDA Connector

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, the 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 select, make sure to have the correct orientation when you plug

in the IrDA connector.

Connect 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy connector FDD and

IDE connector. Be careful of the pin1 orientation. Wrong orientation may cause system

damage.

ATA 33/66/100

IDE Connector

Attach the power LED, speaker, and reset switch connectors to

the corresponding pins. If you enable “Suspend Mode” item in

BIOS Setup, the ACPI & Power LED will keep flashing while the

system is in suspend mode.

Locate the power switch cable from your ATX housing. It is

2-pin female connector from the housing front panel. Plug this

connector to the soft-power switch connector marked SPWR.

6. Support 2nd USB Port

This motherboard provides four 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 the other USB connector to the back panel or front panel

of chassis.

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

The South Bridge ICH2 includes a fast Ethernet controller on chip. On the strength of Intel

82562ET PHY on board, which is a highly-integrated Platform LAN Connect device, it

provides 10/100M bps Ethernet for office and home use, the Ethernet RJ45 connector is

located on top of USB connectors. The green LED indicates the link mode, it lights when

linking to network and blinking when transferring data. The orange LED indicates the

transfer mode, and it lights when data is transferring in 100Mbps mode. To enable or

disable this function, you may simply adjust it through BIOS.

17. BIOS Upgrade under Windows Environment

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

and it’s STRONGLY RECOMMMANDED 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: WAX4BG2102.ZIP) with WinZip

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

3. Save the unzipped files into a folder, for example, W AX4BG2102.EXE & W

AX4BG2102.BIN.

4. Double click on the W AX4BG2102.EXE, EZWinFlash will detect the model name

and BIOS version of your motherboard. If you had got the wrong BIOS, you will no

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!

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

accordingly to resolve the problem.

Part Number and Serial Number

Install the VGA card. Then connect your monitor and keyboard.

The problem was probably caused

by power supply or motherboard

failure. Please contact your reselle

or local distributor for repairing.

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

“Load Setup Default".

The problem should be caused by the

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.

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.
