When 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 of our AOpen motherboards include many amazing and powerful
features, but in some situations, these powerful features are not used to every user. Hence, some of these key features are
changed optional for you choose. Optional functions that can be upgraded by users, we call them "Upgrade Optional". As for those
optional functions that can't be upgraded by yourself, we call them "Optional". If needed, you can contact our local distributors or
resellers for purchasing "Upgrade Optional" components, and either you can visit AOpen official web site:
