2Introduction
Unpacking the Mainboard
The mainboard package contains:
¥ The 82430VX 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.

Important: Make sure the system is well ventilated to prevent
overheating and ensure system stability.

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 this jumper; then
open the jumper to retain new settings.

6Hardware Setup
EMI1/EMI2/EMI3 (JP52/EMIGND/JP53): EMI Ground Jumper
These 3 jumpers are located in three different places and they are
designed for eliminating the EMI signals. Short or open these 3 jumpers
together when is needed.
