l

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 unpacking and installing the mainboard.

1.

the

Mainboard

The 80486 Mainboard This User’s Guide

Touch an unpainted area of the system chassis before

.

handling the mainboard or any component. Doing so discharges the static charge your body may have built.

2.

3.

Do not apply power if the mainboard appears damaged. If there is damage to the board, or items are missing, contact your dealer immediately.

Remove the mainboard from its anti-static wrapping and place it on a grounded surface, component side up.

Inspect the mainboard for damage. Shipping may have loosened integrated circuits from their sockets. If any integrated circuit appears loose, press carefully to seat it firmly in its socket.

Hardware Configuration

Before you install the 80486 mainboard into the system chassis, you may find it convenient to first configure the mainboard’s hardware. This chapter describes setting jumpers, installing memory modules, and attaching components.

Power Precautions

Before you begin configuration, make sure you are working

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. Take the following precautions:

0

l

Turn off the power supply, and unplug the power cord before you begin.

Unplug all cables that connect the mainboard to any external devices.

Jumper Switch Settings

You can configure hardware options by setting jumper switches on the mainboard. See Figure 1-l for jumper locations. Set a

jumper switch as follows:

0

Short a jumper by placing the plastic jumper cap over two pins of the jumper.

0

Open

the pins of a jumper by removing the jumper cap.

Power Supply Requirements

You need a clean, steady power source to get the best performance from your system. For reliable performance, make sure your power supply provides a voltage range of 5.25 volts maximum to 4.75 volts minimum. If your area has noisy power

transmission, use a line noise filter between the power source

and your computer. You must make sure the power supply can supply the total

power required by all the devices in your system. Check the power requirements of the floppy disk drives, hard disk drives, and any additional boards that you will use. In a

system that includes a hard disk drive and installed adapter

cards, use a power supply of at least 180 watts.

‘1 2

Installing the Mainboard

Before you begin, check the location of the mounting holes in the case and on the mainboard.

Caution: Static electricity can damage the mainboard.

Install the 80486 mainboard as follows:

Chapter 3

_. .

1.

4.

5.

Review the section on static electricity precautions at the beginning of this manual.

Place the case on an anti-static mat and remove the cover. Remove the nylon stand-offs and screws for mounting the mainboard.

Put the front of the case to your right and the rear to your left. The mainboard occupies the section of the case nearest you; the power supply goes on the far side.

Align the mounting holes on the case to the mounting holes on the mainboard. Make sure you can access the keyboard connector

(Jl

once the board is installed.

From the bottom of the mainboard, insert stand-offs into the proper holes on the board, and attach the mounting screws to the bottom of the case.

Note: Some cases do not use stand-o@ and mounting screws; in this

case you can fasten the mainboard into the case with regular

screws.

6.

Place the mainboard securely with regular

into the case and fasten the board screws.
