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. JP14 Clear CMOS

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.

PART NO: 90.51Q30.001 DOC. NO: AX4BRU-EG-E0209B

You can clear CMOS to restore system default setting. To

clear the CMOS, follow the procedure below.

1. Turn off the system and unplug theAC power.

2. RemoveATX 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. ConnectATX power cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

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 SYSFAN2 or FAN3 (AUX Fan) connector.

5. Installing DIMM Module

This motherboard has two 184-pin DDR DIMM sockets that allow you to install DDR200 o

DDR266 memory up to 2GB.

3. Installing Processor

Note: If you do not match the CPU

socket Pin 1 and CPU cut edge well, it

may damage the CPU.

CPU socket lever CPU cut edge

Note: Some CPU fans do not have

sensor pin so they cannot support fan

monitoring.

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.

6. Installing CPU & System Fan

Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE

connector. Pin1 of cable is normally marked with red color. Addition to IDE connectors, we

also provide two RAID IDE connectors for you to connect RAID. Be careful of the pin1

orientation. Wrong orientation may cause system damage.

9. Connecting WOL

10. Connecting Front Panel Cable

8. Connecting COM2 Connector

This motherboard comes with a COM1 connector on the back panel. However, we provide

an extra COM2 connector for your convenience. Once you need to connect a device via

COM2, just connect a suitable cable on it.

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 managemen

software, such as ADM, for the checking of how to wake up the system. Note that, at least

600mAATX standby current is required to support the LAN card for this function.

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.

7. 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 o

chassis.

11. STBY LED

STBY LED is AOpen’s considerate design that we aim at providing you friendly system

information. The STBY LED will light up when power is provided to the motherboard. This is

a convenient indication for you to check the system power status in many circumstances

such as power on/off, stand-by mode and RAM power status during Suspend to RAM

mode.

The onboard I/O devices are PS/2 Keyboard, PS/2 Mouse, COM1, VGA port, Printer, USB, and

LAN ports. The view angle of drawing shown here is from the back panel of the housing.

14. Enlarged Aluminum Heatsink

12. Support 10/100Mbps LAN Onboard

The Intel 82551QM includes a fast Ethernet controller on chip. On the strength of this LAN

controller 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.

Cool down CPU and Chipset is important for system reliability. Enlarged aluminum heat sink

provides better heat consumption especially when you are trying to over clocking the CPU.

Model name and BIOS version can be found on upper left corner of first boot screen

(POST screen). For example:

17. Installing Intel IAA Driver

Windows 95/98 cannot recognize this chipset, because it was released before the Intel

845E chipset. You can install the Intel INF Update Utility from the Bonus Pack CD auto-run

menu to eliminate the “?” marks.

You can install Intel IAA Driver to increase the performance of software applications and

reduce PC boot times. You can find it in the AOpen Bonus Pack CD.

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.

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.
