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.
