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.

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 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:

You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedure below.
1. Turn off the s ystem and unplug the AC power.
2. Remove ATX power cable from connector PW R2.
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.

This motherboard supports Intel® Pentium III®(Both Coppermine and Tualatin are supported) and Celeron™ Socket 370 series
CPU. Be careful of CPU orientation when you pl ug it into CPU socket.
1. Pull up the CPU socket level and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on t he
CPU upper interface. Match Pin 1 and cut edge, then ins ert the CPU into

This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if you are not overclockers, we
recommend you to set at the default setting. By the way, this motherboard also provides “1MHz S tepping Adjus tment ” feature
for overclockers. You can adjust CPU FSB frequency via BIOS setup program. Based on the CPU type, the adjustment range
has three level: 66~83 (FSB=66MHz, such as Celeron™ 533), 75~124 (FSB=100, such as Pentium

Adjustable CPU Core Voltage from 1.05V to 1.825 by 0.05 st epping. But this motherboard can also automatically detect CPU
VID signal and generates proper CPU c ore voltage.

Warning: Higher CPU core voltage may be
able to increase CPU speed for overclocking,
but you may damage the CPU or reduce the
