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 notice that some of the functions are
marked as “User Upgrade Optional” or “Manufacture Upgrade Optional”. Although all of AOpen’s motherboards have included
many amazing and powerful features, sometimes not every user is familiar with these powerful features. As a result of this we
define features that can be upgraded by users as “User Upgrade Optional”. You can upgrade these functions by purchasing
additional devices. As for functions that cannot be upgraded by users, we define them as “Manufacture Upgrade Optional”. If
need be, you can contact our local distributors or resellers to purchase “Manufacture Upgrade Optional” components, and again
you are also welcome to visit our official website at english.aopen.com.tw
for detail information.

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.
