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 www.aopen.com
for 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 pin1 & 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.
Note: These pictures are for example only; it may not look exactly the same with the motherboard you purchased.

Note: P4 CPU tends to produce higher
temperature; for better heat dissipation,
we recommend you to install this
motherboard with a bigger housing.
Besides, by doing so you can preven
components from colliding.
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well, it
may damage the CPU.
Note: This socket supports
Micro-FC-PGA2 package CPU, which
is the latest CPU package developed
by Intel. Other forms of CPU package
are impossible to be fitted in.

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
