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
“Optional”, and some are called “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
“Optional” for you to choose. Some optional functions that can be upgraded by users, we call them “Upgrade Optional”. As for
those optional functions that can’t be upgraded by ourselves, we call them “Optional”. If needed, you can contact our local
distributors or resellers for purchasing “Upgrade Optional” components, and again you can visit AOpen official web site:
www.aopen.com
for more detail information.

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 (Brookdale). 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.
