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.
W hen 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”. Though all AOpen motherboards include many amazing and powerful
features, in some situations, these powerful features are not used to every user. Hence, we changed some key features as
“Optional” for you to choose. Some optional functions that can be upgraded by users, we call them “Upgrade Optional”. As for
those optional functions that can’t be upgraded by ourselves, we call them “Optional”. If needed, you can contact our local
distributors or resellers for purchasing “Upgrade Optional” components, and again you can visit AOpen official web site:
