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.

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 choose. 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
Optional” components, and again you can visit AOpen official web site: http://english.aopen.com.tw/

This motherboard supports AMD® Athlon 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 powered off when the
temperature of CPU reaches to 97 degree, but it works only on AthlonXP CPU).
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.

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,
new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This
motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power
supply for providing full line over-current protection.
Note: Although we have implemented protection circuit try to prevent any human operating
mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this
motherboard may be damaged because of component failure, human operating error or unknown
nature reason. AOpen cannot guaranty the protection circuit will always work perfectly.

CPU Ratio
CPU FSB
(By manual Adjustment)
Warning: VIA® Apollo KM400 chipset supports
166MHz FSB (with performance reaching maximum
333MHz EV6 system bus) and 66MHz AGP clock,
higher clock setting may cause serious system
damage.
Home
From 5.5x to 16.5x step 0.5x; 17x to 18x step 1x
FSB=133, 133~165 by 1MHz stepping adjustment technology
FSB=166, 166~199 by 1MHz stepping adjustment technology
Warning: If you have adjusted CPU ratio on your
current CPU and plan to replace a new CPU, please
use <Home> key or Clear CMOS to restore the
default setting. The system will implement the
revious CPU setting on the new one.
Tip: If your system hangs or fails to boot when
overclocking, please use <Home> key to restore the
default setting or wait AOpen “Watch Dog ABS” for
resetting the system in few seconds and the system
will auto-detect hardware again.

damage caused by overheat,
CPU Overheat Protection circuit
had been especially designed on
this motherboard. System will
automatically power off when this
motherboard detects the CPU
temperature higher than 97

This motherboard has two 184-pin DDR DIMM sockets that allow you to install DDR266/333 memory up to 2GB. Non-ECC DDR
RAM is supported. Otherwise, it will cause serious damage on memory sockets or RAM module.
Warning: This motherboard supports DDR
RAM. Please do not install the SDRAM on
the DDR RAM sockets; otherwise serious
damage may occur on memory sockets or
SDRAM module.

Please follow the procedure as shown below to finish memory installation.
1. Make sure the DIMM module’s pin face down and match the socket’s size as depicted below.
2. Insert the module straight down to the DIMM slot with both hands and press down firmly until the DIMM module is securely
in place.
3. Repeat step 2 to finish additional DIMM modules installation.
