2Introduction
Unpacking the Mainboard
The mainboard package contains:
¥ The 82430TX Mainboard
¥ This UserÕs Guide
¥ One IDE Bus Master driver diskette
Note: Do not unpack the mainboard until you are ready to install it.
Follow the precautions below while unpacking the mainboard.
1. Before handling the mainboard, ground yourself by grasping an
unpainted portion of the systemÕs metal chassis.
2. Remove the mainboard from its anti-static packaging and place it on
a grounded surface, component side up.
3. Check the mainboard for damage. If any chip appears loose, press
carefully to seat it firmly in its socket.
Do not apply power if the mainboard appears damaged. If there is
damage to the board contact your dealer immediately.
Electrostatic Discharge Precautions
Make sure you ground yourself before handling the mainboard or other
system components. Electrostatic discharge can easily damage the
components. Note that you must take special precaution when handling
the mainboard in dry or air-conditioned environments.
Take these precautions to protect your equipment from electrostatic
discharge:
¥ Do not remove the anti-static packaging until you are ready to install
the mainboard and other system components.
¥ Ground yourself before removing any system component from its
protective anti-static packaging. To ground yourself grasp the
expansion slot covers or other unpainted portions of the computer
chassis.
¥ Frequently ground yourself while working, or use a grounding strap.
¥ Handle the mainboard by the edges and avoid touching its
components.

2 Hardware Setup
This chapter explains how to configure the mainboardÕs hardware. After
you install the mainboard, you can set jumpers, install memory on the
mainboard, and make case connections. Refer to this chapter whenever
you upgrade or reconfigure your system.
CAUTION:Turn off power to the mainboard, system chassis, and
peripheral devices before performing any work on the
mainboard or system.
Jumpers
JP5: CMOS Clear Jumper
Clear the CMOS memory by momentarily shorting pin 2Ð3; then
shorting pin 1Ð2 to retain new settings.

JP40: CE Test Jumper Pin
This connector is reserved for the CE test. If you run into problems
during the CE test, unplug the jumper pin and try again.

6Hareware Setup
JP2: Smart Detect CPU Voltage Function Auto/Manual
Jumper
This jumper is reserved for few old non-Intel CPUs which can not be
detected correctly. If you run into problems while detecting the voltage
of old non-Intel CPUs, remove this jumper to correct it.
JP37: DIMM Voltage Select Jumper
Most of DIMMs in the consumer market is still 3.3V and this jumper is
reserved only for upgrading purpose in the near feature. If you have 5V
SIMM or DIMM which matches the existing 3.3V DIMM socket on this
mainboard, than you need to set this jumper to 5V before installing the
SIMM or DIMM.
DIMM Voltage JP37

Caution: Do not change this jumper to 5V setting unless you are sure
that your DIMMs are 5V. The wrong setting may cause the
system malfunction.
