This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: El ectrostatic 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 t hroughout 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 s ome 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

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.
Note: These pictures are for example only, it may not exactly be the same motherboard.
3. Press down the CPU socket lever and finish
