About “Optional” and “Upgrade Optional”…
When you read this online manual and start to assemble your computer system, you may find some of functions are “Optional”,
and some are “Upgrade Optional”. This is because all of AOpen motherboards include many amazing and powerful features;
however, some of these are not frequently used on daily operation. Therefore, we define some key features as optional to meet
different requirements. Functions that can be upgraded by users, we define them as “Upgrade Optional”. The other optional
functions that may have been built on the motherboards and you cannot upgrade by yourself, we call them “Optional”. If needed,
you can contact your local distributors or resellers to purchase “Upgrade Optional” components. Also you can visit AOpen official
web site: www.aopen.com.tw <http://www.aopen.com.tw>
to get detailed information.

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.

This motherboard supports AMD Athlon & Duron Socket 462 CPU. 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 black dot or cut
edge on the CPU upper interface. Match Pin 1 and cut
edge. Then insert the CPU into the socket.
3. Press down the CPU socket lever and finish CPU
installation.
Note: If you do not match the CP
socket Pin 1 and CPU cut edge well,
ou may damage the CPU.

Based on high CPU operating frequency, the AMD® Athlon™/Duron™ Socket 462 series CPU requires heatsink with cooling fan
when it is powered up. AOpen provides two new features in an easy and user friendly BIOS setting to protect your CPU
investment, preventing CPU operati ng under overheat condition or CPU gets damaged by the high temperature if cooling fan
fails or is under the designated speed (RPM).

If the "CPU Cooling Fan Malfunction Protection" function is enabled, BIOS will monitor CPU cooling fan speed immediately.
If the cooling fan speed is lower than (500) RPM or failed, the system will shutdown automatically to protect CPU. You also can
