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
for detail information.
