Installing and Removing Options

Installing an Option Card

This section explains how to install option cards in your computer. Your computer has three 16-bit full-length slots and two 8-bit half-length slots to accommodate a total of five option cards.

Usually it does not matter which slot an option card occupies as long as the card fits in the slot. For example, you can place some 8-bit cards in a 16--bit slot. However, you cannot install a 16-bit card in an 8-bit slot.

Caution

Make sure the power requirements for the option cards you

install do not exceed the power supply limitations. See your

option card manual(s) for the power requirements. Then check Appendix A for the option slot power limits. Note that older option cards that require -5 volts are not supported.

Before you install an option card, see if you need to change any

jumper settings on the system board. For example, if you install

a video card, you may need to change jumpers J11, J15, or J36

and J37. See page 3-6 for more information on jumpers. Refer to the illustration below and follow these steps to install

an option card:

If you are using a 16-bit option slot, go on to step 2.

If you are using an 8-bit slot near the power supply, you need to remove the power supply before you can remove the

metal slot cover.

Remove the retaining screw securing the option card to the computer. Then pull the card straight out of the slot.

Set the card aside with the component side facing up.

Adding Video Memory

Your computer comes with 256KB of video memory. You can

increase your video memory to either 512KB or 1024KB by installing four or six video DRAM, 20-pin, 70ns or 80ns, 44256 DIP (Dual Inline Package) chips. This is useful for running graphics-intensive applications or for supporting resolutions up to 1024 x 768 on your monitor. See Appendix A for a table identifying supported colors and resolutions for each amount of video memory.

For the memory to work properly, you must install chips in the following configuration (each bank contains two video memory chips).

Connecting the Drive and Power Cables

To connect the drive to the computer, you need to connect both the drive ribbon cable and a power supply cable. Follow the

steps below.

If you are installing a diskette drive, locate the diskette drive ribbon cable. The middle of the cable is connected to the system board.

4-14

If you are installing a second diskette drive, one end of the cable is connected to the bottom diskette drive. The cable contains both a card-edge connector and a header

connector.

Installing and Removing Drives

If you are installing a hard disk drive in the upper horizontal bay, make sure you use the proper hard disk drive ribbon cable and connect the drive to the hard disk drive connector. Also, if this is the second hard disk drive in your system, make sure you set the jumpers on both hard disk drives to indicate which is the master and which is the slave drive.

If the drive connector extending from the back of the drive has gold contacts on both sides, use the card-edge connector on the ribbon cable. Make sure you align the key-way (the plastic divider) with the gap in the drive

connector.

If the drive connector contains a series of pins, use the header connector. Identify pin 1 on the drive and align the connector so that the red wire is at pin 1.

Locate one of the power supply cables that lead from the

power supply. (They have multi-colored wires and a plastic

connector on the end.)

Installing Video Drivers

The Utility diskettes included with your system contain enhanced VGA (video graphics array) drivers and utilities for your computer’s built-in VGA adapter. This chapter describes how to install and use these drivers and utilities.

Your computer’s built-in VGA adapter is compatible with IBM VGA. The drivers and utilities described in this chapter work with any VGA and compatible, multifrequency monitors that

use analog input. Standard VGA monitors display resolutions up to 640 x 480,

and you do not need to install the drivers or utilities for your

system to operate properly with your application programs at

this resolution.

However, if you want to use resolutions over 640 x 480 or take

advantage of the following special features when using certain

application programs, you need to install the appropriate

drivers:

Enhanced graphic and text modes in 4, 16, and 256 colors

Resolutions up to 1024 x 768

Extended text mode for 132-column text with 25, 30, 43, and 60 rows.

Your computer comes with 256KB of video memory installed

on the system board. You can upgrade the video memory to

either 512KB or 1MB by installing additional video memory

chips, allowing you to use higher resolutions and more colors.

See Chapter 3 for installation instructions.

Troubleshooting 6-9

Option Card Problems

A newly installed option card is not working correctly.

Make sure the option card is installed correctly and is well-seated in its slot. Run the SETUP program to update your computer’s configuration after you install the card. Also, perform setup procedures for any software you are using with the option card.

Also, see the documentation that came with the option card to

set any necessary DIP switches or jumpers on the card.

The main system board of your computer may also have some jumpers that must be set for the option card to work properly. See Chapter 3 for system jumper information.

Your system may need to operate at the slower processor speed

to access the device. Try reducing the processor speed (see Chapter 2) or inserting a wait state through the SETUP program (see Chapter 1).

You may have inserted an older option card that works at

-5

volts. Make sure you install option cards that meet the

system’s power requirements.

An external device connected to the option card is not

working correctly.

Make sure you are using the proper cable to connect the device to the card.
