When you read this online manual and start to assemble your computer system, you may find some of functions are called
“Manufacturer Upgrade Optional”, and some are called “User 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 “Manufacturer Upgrade Optional” for you to c hoose. Some optional functions that can be upgraded by
users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them
“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade

You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedure below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pins 1 & pin2.
5. Connect ATX power cable back to connector PWR2.

Tip: If your system hangs or fails to boot because of
overclocking, simply use <Home> key to restore the
default setting or you can wait the AOpen “Watch Dog
Timer” reset the system after five seconds and system
will auto-detect hardware again.
