CHAPTER 2: JUMPERS & CONNECTORS

When working with the 486MIS,

it is extreme y important that

you avoid static e ectricity.

A ways ground yourse f by

wearing a wrist or ank e strap.

Figures 1 on the next page sho s the component layout of the 486MIS

system board ith locations of the system board jumpers and

connectors. Note that most jumpers and connectors on the system board

are labeled ith proper names ith pin 1 marked as '1'. To avoid

damaging the board and to have proper operation caution should be

taken hen connecting these components.

SYSTEM BOARD JUMPERS

Jumpers are used to select bet een various operating modes. A jumper

s itch consists of t o, three, or four gold pins projecting from the system

board. Placing the plastic jumper cap over t o pins connects those pins

and makes a particular selection. Using the cap to cover t o pins in this

ay is referred to as shorting those pins. If the cap is not placed on any

pins at all, this is referred to as leaving the pins open.

Note: When you open a jumper, leave the plastic jumper cap attached

to one of the pins so you don't lose it.

CPU Externa C ock Jumpers

If you are installing an i486DX, or i486SX the internal CPU clock speed is

the same as the external CPU clock speed. This is different for i486DX2

CPU here the external speed is one-half of the internal speed. For

example, a 486DX2-66 has an external clock speed of 33MHz.

Care should be taken hen installing the CPU into the Pin Grid Array

(PGA) socket on the system board. Make certain that pin 1 of the CPU

chip is correctly aligned ith pin 1 of CPU socket. The location of pin 1

on the CPU is denoted by a small notch.

C ear Password Jumper

Jumper JP32 is used to clear the system pass ord if user ere to forget

it.

Function JP32

Normal Pass ord Operation OPEN

(Default)

BIOS performs infinite loop test and clears

system pass ord

SHORT

Follo these steps to clear system pass ord:

1. Turn po er OFF.

2. Open the system cover and gain access to jumper JP32 and W1.

3. Short jumper JP32 and disable SCSI BIOS through jumper block W1

as sho n belo :

¢¢¢¢¢

I1 I2 B1 B2 E

4. Turn po er ON.

5. Wait for the system to finish one self-test loop, then turn po er OFF

again.

6. Open jumper JP32 and re-enable SCSI BIOS through W1.

7. Replace and secure the system cover.

8. Turn po er ON, pass ord data should be cleared.
