This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your proc essor, 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 throughout any procedure requiring
ESD protection.

When you read this online manual and start to assemble your com puter system, you may f ind some of functi ons are called “Optional”, and
some are called “Upgrade Optional”. Though all AOpen motherboards include m any 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: www.aopen.com

You can clear CMOS to restore system default setting. To clear 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 pin 1 & pin 2.
5. Connect ATX power cable back to connector PWR2.

This motherboard supports Intel® Pentium 4 Socket 478 series CPU (Willamette / Northwood). Be careful of CPU orientation when you plug
it into CPU socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Loc ate Pin 1 in the socket and look for mark on the CPU upper interface.
Match Pin 1 and cut edge, then insert the CPU into the socket.
Note: Those pictures are for example only; they may not look the same with the motherboard you purchased.

This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS setup, and no jumpers or switches are needed.
The default setting is "table select mode". You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.

Warning: Intel® 845E chipset supports maximum
400MHz (100MHz*4) / 533MHz (133MHz*4) system bus
and 66MHz AGP clock; higher clock setting may cause
serious system damage.

you may not be able to adjust the clock ratio
in BIOS manually.

This motherboard has three 184-pin DDR DIMM sockets that allow you to install PC2100 memory to 3GB or PC2700 memory up to 2GB.
Please note that when you install PC1600 or PC2100 DDR SDRAM, you can install them ful ly into 3 sockets; however, when you install
PC2700 DDR SDRAM, we suggest you to install DIMM1 and DIMM2 ONLY.
