motherboard can support Intel
different customer’s requirements, the Intel 845GE chipset memory interface supports DDR333/266 SDRAM devices with
densities of 64, 128, 256, 512Mb DDR RAM DIMM modules and the maximum memory size can be up to 2 GB (Please note
that only CPU FSB 533 supports DDR333). The onboard IDE controller supports Ultra DMA
rate up to 100MB/s. Further flexibility can be achieved by taking advantage of the Communication and Network Riser (CNR)
card option that allows audio, modem configuration on a single baseboard
design. More than that, on the strength of RealTek RTL8100BL
controller on board, which is a highly integrated Platform LAN
Connect device, it provides 10/100M bps Ethernet for office and
home use. Besides, the AX4GE FM has an AC97
chipset onboard, providing high performance and magic

This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and
other components. Always observe the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a
component. If a wrist strap is not available, maintain contact with the system unit throughout any
procedure requiring ESD protection.

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 choose. 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
Optional” components, and again you can visit AOpen official web site: www.aopen.com.

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.

This motherboard supports Intel® Pentium 4 Socket 478 series CPU. Be careful of CPU orientation when you plug it into CPU
socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a cut edge on the CPU upper
interface. Match Pin 1 and cut edge, then insert the CPU into the socket.

This motherboard comes with a retention module attached on the CPU socket when shipped, we strongly recommend you to
install AOpen special designed CPU Fan as shown below on the retention module for better heat dissipation. Please install the
CPU Fan correctly as the following pictures shown.
1. Gently put the CPU Fan down on the
retention module with clips aligning
correctly to the four corners.
2. Pressing down the four clips with force one by

With this motherboard, AOpen provides a very special, useful feature for overclockers. When you
power-on the system, the BIOS will check last system POST
enable “Watch Dog Timer” function immediately, and set the CPU FSB
that stored in the BIOS. If system failed in BIOS POST, the “Watch Dog Timer” will reset the
system to reboot in five seconds. Then, BIOS will detect the CPU’s default frequency and POST
again. With this special feature, you can easily overclock your system to get higher system performance, and without removing
the cover of system housing to set the jumper to clear CMOS data when your system hanged.

FSB Clock System Bus Ratio
AGP Clock = PCI Clock x 2
Note: Since the latest processor,
Northwood, would detect the clock
ratio automatically, you may not be
able to adjust the clock ratio in
BIOS manually.
