INSTALLATION GUIDE
CPU - It is recommended for installation of AMD K6 MMX 233 and Cyrix M1
PR200 CPU to be installed with certified CPU Cooler (Big Cooler) from the
approved suppliers. Insufficient Cooling for the CPU may render the system
unstable. Our SMART SOFT capabilities BIOS will chec for the ID code of the
CPU and if the CPU ID code does not match your CPU mar ing, then return them
as it is re-mar ed from the original mar ing. Chec that the CPU is firmly
installed on the CPU soc et and CPU Cooler secured before powering up the
system.
Memory - Best Recommended for 60ns EDO DRAM on SIMMs memory. Do
not mix SDRAM (3.3V) with EDO 5V type of memory. Please chec for re-
mar ed 60ns EDO DRAM by visual inspection of the surface on the components.
Most re-mar ed memory will show polished surface. We do not guarantee
reliability for re-mar ed memory. For BIOS setting for DRAM configuration, it is
advisable to set the default setting for initial chec ing of the system. Good
performance needs all installed configuration device installed for excellent quality
including memory, hard dis , VGA and others.
Hard Disk - For best performance, it is best recommended to install Ultra
DMA/33 mode hard dis . It wor s in conjunction with Ultra DMA 33 drivers on
our utility dis attached.
VGA - For best compatibility, the ATX431 has been tested with famous VGA
brand li e ExpertColor VGA, Diamond, ATI, Matrox series. The VGA should be
4 layers PCB type for good display reliability with certified EMI test li e CE or
DOC (FCC).
BIOS - Setup the system as “Optimal Default Setting”.
Cab es - ATX431 can prevent reverse connection with connector brac et.
Chec if each cables has been connected to their respective device before power-
up.

Static E ectricity Precautions
Static electricity can easily damage your mainboard. Observing a few basic
precautions can help you safeguard against damage that could result in expensive
repairs. Follow the measures below to protect your equipment from static
discharge:
·Keep the mainboard and other system computers in their antistatic pac aging
until you are ready to install them.
·Touch a grounded surface before you remove any system component from its
protective anti-static pac aging. A grounded surface within easy reach is
the expansion slot covers at the rear of the system case. Or any other
unpainted portion of the system chassis.
·During configuration and installation, touch a grounded surface frequently to
discharge any static electric charge that may build up in your body.
Another option is to wear a grounding wrist strap.
·When handing a mainboard or an adapter card, avoid touching its
components. Handle the mainboard and adapter cards either by the edges
or by the mounting brac et that attaches to the slot opening in the case.
Unpacking the Mainboard
The mainboard comes pac ed in a sturdy cardboard shipping carton. The carton
contains:
·The Mainboard
·This User’s Manual
Note: Do not remove the mainboard from its original packing until you are ready
to install it.
The mainboard is easily damaged by static electricity. Observe the following
precautions while unpac ing and installing the mainboard.
1. Touch an unpainted area of system chassis before handling the mainboard or
any component. Doing so discharge the static charge your body may
have built.
2. Remove the mainboard for appearance chec ing. Shipping may have
lossened integrated circuits from their soc ets. If any integrated circuit
appears loose, press carefully to seat it firmly in its soc et.
Do not apply power if the mainboard appears damaged. If there is damage to the
board, or items are missing, contact your dealer immediately.
Power Precautions
Before you begin configuration, ma e sure you are wor ing with an unplugged
mainboard. Many components are powered by low-voltage current, but there still
may be a dangerous electric current coming from the leads and power supply.
You should ta e the following precautions:
·Turn off the power supply, and unplug the power cord before you
begin.
·Unplug all cables that connect the mainboard to any external devices.
Note: Before making connections to the board, make sure that power to the system
is turned off.

INTRODUCTION
Attention:
For new CPU installation, please press the “Home” ey to clear the previous
setting to return to Default Setting. To configure your CPU, choose the SMART
SOFT Setting from the BIOS Setup Screen. You can then set the CPU frequency
or others.
IMPORTA T OTICE
After you have assembled the motherboard with its system conguration
installed, check that all the cables attached are correctly connected as
required before powering on the system. The rst procedure you are
required to do is to press the “D L” key on the keyboard during displaying
memory counting and access the “System BIOS Setup”. Select the “SMART
SOFT CPU Setting” to congure the CPU speed according to the CPU
installed.
SMART SOFT provides you with CPU Auto-Voltage Detection, CPU ID type
and Soft frequency setting on the BIOS “SMART SOFT CPU Setting” option.
You need only to setup the CPU speed type on the BIOS according to the CPU
installed. In the case of wrong or over-rating setting of the CPU Frequency
which exceeds your CPU speed limit, it may render the system failure to
bootup, or no display at all. SMART SOFT provides you with the “Return to
Default setting” for minimal CPU setting.
Press the “HOME” key on the keyboard simultaneously upon
power-up for the system to return to efault setting.
This action will clear the CMOS memory for the system conguration to
Default value. You can also Hardware Clear CMOS with the jumper
indicated on the motherboard.
