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
“Optional”, and some are called “Upgrade Optional”. Owing to all of AOpen motherboards include many amazing and powerful
features, but in some situations, these powerful features are not used to every user. Hence, we make some key features change
to optional for you choose. Some of these optional functions can be upgrade by users, and therefore we called these optional
functions are “Upgrade Optional”. About the optional functions that you can’t upgrade by yourself, we called them “Optional”. If
needed, you can contact our local distributors or resellers for purchasing “Upgrade Optional” components, and again you can

This motherboard supports Intel® Pentium® 4 1.30~1.50GHz+ Socket 478 series CPU. Please follow the step as below to finish
CPU installation. Be careful of CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket level and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or 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; they may not exactly be the same as the motherboard you purchased.
