This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic 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 throughout
any procedures requiring ESD protection.

You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedures 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 AMD® Athlon and Duron Socket 462 series CPU. Be careful of CPU orientation when you plug it into
CPU socket (with CPU Overheat Protection function implemented, the system will be automatically power off when the
temperature of CPU reached 97 degree, but works on AthlonXP CPU only).
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the
CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into
the socket.

With AMD platform substantially keeps increasing the speed of its CPU, it inevitably led to the annoying problem of high CPU
operation temperature at the same time. In order to prevent accidental failure of CPU fan, which could cause the burning down
of the AthlonXP CPU, we, AOpen, have meticulously developed a new technology, named, O.H.P. (Overheat Protection)
Technology to protect them. Thanks to the intelligent monitoring design of AOpen O.H.P. technology, user can now finally set
their mind at ease even when fan failed to work without fearing the possible damage of CPU.
Under the circumstances that CPU fan is running properly, AthlonXP temperature should be way below the highest temperature
limit of 97℃. However, if CPU fan accidentally becomes
malfunction or improperly installed, the CPU temperature
would rocket abruptly, and you may find your system hang
up or crying over the smoking CPU if you haven’t installed
AOpen O.H.P. previously. With AOpen O.H.P. technology
applied, the specific thermal detection pins on AthlonXP
CPU would sense voltage difference when processor is
overheated with fan failed, and the overheat protection
system would immediately send out a signal to abort your
system by cutting CPU electricity before any damage is
done. Unlike other manufacturers who use BIOS or
software to control the power supply of CPU, AOpen O.H.P.
Technology is purely hardware-controlled the minute after
system boot-up, and occupies no system resource. We are
pleasant to phase in this practical function on all AOpen
AMD series motherboards to protect customer’s valuable
hardware and personal data.

Note: With CPU speed changing rapidly, there might be fastest CPU on
the market by the time you received this installation guide. This table is
kindly for your references only.
Note: You have to adjust CPU
FSB in BIOS after installing
CPU; otherwise CPU will run at
default speed of CPU FSB
value.
Note: : Due to the limitation of
nVidia chipset itself, if the FSB
overclocking frequency is
extremely high, (for example,
over 160MHz), the WatchDog
ABS and Home key function
may not be able to automatically
recover your motherboard. In
such case, please clear CMOS
by JP14.
