Built-in IBM® PS/2™ compatible keyboard and mouse ports

On-board VGA feature connector

Four 16-bit (or 8-bit) ISA option slots

Support for up to three internal mass storage devices

Password security.

Using the built-in interfaces, you can connect your peripheral devices directly to the computer so you don’t have to install option cards. Use the option slots to enhance your system with such functions as a modem card or additional interface ports.

Introduction 1

With 512KB standard video memory, the built-in VGA adapter supports resolutions of up to 800 x 600 (256 colors), and 640 x 480 (64K colors). Extend the video memory to 1MB to support resolutions of 1280 x 1024 (16 colors), 1024 x 768

(256

colors), or 800 x 600 (64K colors).

If you install a high-resolution graphics adapter card or full-motion, multi-media card, you can connect it to the

computer’s VGA feature connector. This allows you to use the adapter’s special graphics features while accessing the standard

VGA signals provided by your main system board.

VGA Utilities

Your computer comes with special VGA drivers and utilities for use with the integrated VGA interface. Use these utilities to take advantage of extended VGA features such as high resolutions and 132-column text mode when you run popular application programs. Instructions for installing and using these drivers are in a readme file called VGADRV.TXT on the Utilities 1 diskette. If your system came configured with a hard disk drive, you may also find this file by selecting the VGA Utils group icon in Microsoft®Windows’“. See page 2-19 for more information.

Optional Equipment

You can easily upgrade your computer by installing additional memory and a wide variety of options, as described below.

(Installation instructions are provided in Chapters 4 and 5.)

System Memory

By adding lMB, 4MB, or 16MB SIMMs (single inline memory

modules) to the main system board, you can expand the

computer’s memory up to 36MB.

2 Introduction

Cache Memory

You can increase the cache memory on your main system board to 256KB by having additional SRAM chips installed by an Authorized Epson Servicer. Additional cache allows your system to access frequently used data faster.

Video Memory

You can add video memory chips to your system board to increase the video memory to 1MB and support higher video resolutions, multimedia graphics adapter cards, or applications

that require higher memory.

OverDrive Processor

You can enhance your 25 MHz or 33 MHz system by replacing your microprocessor chip with an Intel® OverDrive™ processor. This processor doubles the internal clock speed so your system runs much faster.

Math Coprocessor

If you have the 25 MHz system, you may want to install an 80487SX, 25 MHz coprocessor. This optional microprocessor includes a built-in math coprocessor so your computer performs mathematical functions faster.

Drives

Your system supports up to three mass storage devices, including hard disk drives, diskette drives, a tape drive, or a CD-ROM drive.

1-14 Setting Up Your System

Chapter 2

Running the SETUP Program

The first time you use your computer, you need to run the SETUP program to define how your system is set up. You may need to run it again later if you change your configuration.

SETUP is stored in the computer’s read-only memory (ROM),

so you can run it any time you turn on or reset your system.

SETUP lets you verify or change the following:

Current date and time

Type of diskette drive(s) installed

Type of hard disk drive(s) installed

Type of video display adapter you are using

Processor speed

System booting sequence

Diskette drive seek test

System memory

Coprocessor support

Shadow ROM options

Keyboard options

Peripherals options

Password options,

Running the SETUP Program

2-1

The configuration you define through SETUP is stored in a special area of memory called CMOS RAM. This memory is

backed up by a battery, so it is not erased when you turn off or

reset the computer. Whenever you reboot the computer, it checks the settings, and

if it discovers a difference between the information in the CMOS RAM and its actual hardware configuration, it prompts you to run SETUP. You see a message describing the error as well as the following prompt at the bottom of the screen:

Press <Fl> to

run

SETUP or <F2> to continue

If this happens, press to run SETUP and correct the setting.

Another SETUP option displays information about your system board. This information provides a useful reference about jumper and DIP switch settings, SIMM configuration, and hot

key combinations. See page 2-17 for more information.

SETUP also lets you restore the default values for your

configuration. This is useful if you have made changes but

don’t want to keep them; you can restore all the default

Working Comfortably

This section provides tips for creating a comfortable work environment. Following these guidelines for good posture, work habits, and workstation layout can help you avoid problems such as muscle aches, eyestrain, and fatigue.

Using Your Computer

3-1

Sitting at Your Computer

When you use the computer, try to keep your elbows, hips, and knees bent at approximately 90 degree angles and keep your wrists as close to horizontal as possible. (Your hands, forearms, and thighs should be horizontal and your upper arms and lower legs should be vertical.) Your feet should rest firmly on the floor or a footrest.

An adjustable chair allows you to customize your workstation for your body so you can maintain the right posture. To avoid back problems, make sure your chair supports your lower back. Padded armrests let you rest your arms as you work.

To reduce neck strain, keep source documents on a copy stand and position the stand next to the screen at the same eye level.

3-2

Using Your Computer

Work in a relaxed, natural, upright position and let the chair support you. Your elbows should be near your body and level with or slightly lower than the keyboard so your hands rest lightly on the keys. To help you keep your wrists straight, the slope of the keyboard should be no more than 25 degrees. Try not to hit the keys too hard; using too much force creates tension in your hands. Also leave enough room on your work surface so you can freely move the mouse (or other pointing device), and be sure to rest your hands occasionally.

Varying Your Posture and Movements

While sitting at the computer, try to vary your posture and movements. Your seat and backrest should be wide enough and there should be enough room under your desk so that you can sit in a variety of positions throughout the day.

Be sure to occasionally stop working at your computer and perform other tasks. Also take periodic breaks; stand up, stretch, and move around.

Lighting the Room

While it is important to have adequate lighting in your work area, make sure it is not too bright. When a light source is very bright, your eyes get tired by having to continually readjust between the relative dimness of the screen and the bright surroundings. It is best to control the amount of daylight that enters the room and keep bright light sources out of your field of vision when you are looking at the screen.

Using Your

Computer

3-3

Positioning and Viewing the Monitor

Place the monitor directly in front of you and sit about an arm’s length away from it. To minimize glare and reduce eye fatigue, position the monitor so that sunlight, desk lamps, and overhead lights do not shine directly on the screen.

When you are sitting in front of the monitor, the top of the screen should be slightly below eye level so you look down, rather than up, at the screen. If your monitor is too low, you can raise it by placing it (or the computer) on a stand. If the monitor has a tilt and swivel base, you can use it to adjust the position of the screen for comfortable viewing.

To produce an image that is clear and easy to look at, adjust the monitor’s brightness and contrast controls. If your screen flickers, you can minimize it by selecting a dark background using either the brightness and contrast controls or your software.

To prevent eyestrain, rest your eyes occasionally by closing them or focusing on a fixed spot in the distance.

Using Disks and Disk Drives

The disk drives in your computer allow you to store data on disk, and then retrieve and use your stored data. This section tells you how to:

Choose the right diskettes for your drive Write-protect diskettes Insert and remove diskettes Use a single diskette drive system

Format diskettes Make backup copies Care for diskettes Use a hard disk drive.

Types of Diskette Drives

Your system supports the following types of diskette drives:

1.44MB, 3.5-inch

1.2MB, 5.25-inch

q 72OKB, 3.5-inch

360KB, 5.25-inch

MB stands for megabyte, which equals 1024KB (or 1,048,576 bytes). KB stands for kilobyte, which equals 1024 bytes. Each byte represents a single character, such as A, $, or 3.

If your computer has more than one type of diskette drive, or if you use different types of diskettes, you need to be aware of certain incompatibilities between the drives and diskettes. See the following tables.

Because of possible incompatibilities, always label your diskettes with the diskette type and density. (Usually this information appears on the manufacturer’s label.)

Note

If you want to format a 720KB diskette in a 1.44MB drive or a 360KB diskette in a 1.2MB drive, make sure you include the correct parameter in your format command. (In Windows you need to select the drive capacity.) See your operating system manual for instructions.

3-6

Using Your Computer

Write-protecting Diskettes

You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can read it and

copy data from it, but you cannot store new data on it or delete any files it contains.

On a 3.5-inch diskette, the write-protect device is a small switch

on the back of the diskette in the lower right corner, shown

below. To write-protect a 3.5-inch diskette, slide the switch

toward the edge of the diskette until it clicks into position, exposing a hole in the corner.

To remove the write protection, slide the switch toward the center of the diskette until it clicks into position and the hole is covered.

Using Your Computer

3-7

To write-protect a 5.25-inch diskette, cover the small, rectangular notch (shown below) with an adhesive write-protect tab. Write-protect tabs usually are included in a new package of blank 5.25-inch diskettes.

To remove the write protection, peel off the write-protect tab.

Some program diskettes have no switch or notch so they are accidentally erased or altered.

3-8

Using Your Computer

Insertting and Removing Diskettes

To insert a diskette into a 3.5-inch drive, hold the diskette with

the label facing up and the metal shutter leading into the drive, as shown in the following illustration. Slide the diskette into the

drive until it clicks into place.

To insert a diskette into a 5.25-inch drive, hold the diskette with the label facing up and the read/write slot leading into the drive. When you want to remove the diskette, make sure the

drive light is off; then press the release button or flip up the latch. When the diskette pops out, remove it and store it

properly.

Caution

Never remove a diskette or reset or turn off the computer while a diskette drive light is on. You could lose data. Also, remove all diskettes before you turn off the computer.

Using Your Computer

3-9

Using a Single Diskette Drive System

Most operating systems expect the computer to have at least two diskette drives and display prompts and messages accordingly. MS-DOS, for example, recognizes the first diskette drive (the top drive) as drive A and a second diskette drive as drive B. If you have only one diskette drive, MS-DOS can treat it as both A and B when you need to perform operations that normally would use two diskette drives.

For example, if you enter a command to copy data from A to B,

MS-DOS copies the data from the first diskette you place in the

drive (which would be drive A) to the computer’s memory.

Then MS-DOS prompts you to insert another diskette (for

drive B) and copies the data from memory to the new diskette.

When copying is complete, you see a prompt to insert the

original diskette (A). Because you may often swap diskettes this way, it is important

to remember which diskette is which. It is also a good idea to write-protect your original diskette. (See “Write-protecting Diskettes,” on page 3-7.)

If you have a hard disk and one diskette drive, you can load the operating system and application programs from the hard disk, create and store your data there, and use the diskette drive just for copying data to or from diskettes.

However, if you have only one diskette drive and no hard disk, you need to use that drive to load the operating system as well as any application program you are using. First, insert the operating system diskette in drive A and load the operating system; this copies it to the computer’s memory (RAM) so you do not need to leave the system diskette in the drive. Then remove the system diskette and insert your application program diskette to load that data into memory, too. See your application program manual for detailed instructions.

3-10

Using

Your Computer

Formatting Diskettes

Before you can store data on a new diskette, you must format it. Formatting prepares the diskette so that the operating system can write data on it. You need to do this only once, before you use the diskette for the first time.

You can also reformat previously used diskettes to store new data. This process erases all the data on the diskette, so be sure you do not want to save any of the files on a used diskette before you format it. See your operating system manual for instructions on formatting diskettes.

Making Backup Copies

It is important to make copies of all your data and system diskettes. Make backup (or working) copies of all diskettes that contain programs, such as your operating system and VGA Utilities diskettes; then use only the copies. Store the original diskettes away from your working diskettes. Also, copy your data diskettes regularly, whenever you revise them, and store them away from your originals.

If you have a hard disk, you’ll probably use it to store the programs and data files you use regularly. Keep backup copies of all your files on diskettes or tapes (if you have a tape backup drive).

Using Your Computer

3-11

Caring for Diskettes

Follow these simple precautions to safeguard your data and lengthen the life of your diskettes:

Avoid leaving diskettes near magnetic fields that can erase the data, such as those generated by electric appliances or cordless telephones. Never place a diskette on top of your monitor or near the hard disk drive.

Small particles of dust or dirt can scratch the magnetic

surface, destroy data, and ruin the read/write heads in a diskette drive, so store diskettes in a diskette container away from dust and dirt.

Extreme changes in temperature can also destroy data. Keep diskettes out of direct sunlight or extreme cold.

See your diskette packaging for other guidelines.

Using a Hard Disk Drive

Using a hard disk is similar to using a diskette. However, the hard disk provides several advantages:

A hard disk can store many times more data than a diskette.

Your computer can perform all hard disk operations faster.

You can store frequently used programs and data files on

the hard disk, eliminating the inconvenience of swapping diskettes to access different files.

The added storage capacity makes it easy to move back and forth between different programs and data files. However, because it is so easy to add programs and files to your hard

disk, you may find yourself trying to organize hundreds of files.

3-12 Using Your Computer

Most operating systems let you keep related files together in directories and subdirectories so they are easy to find and use. See your operating system manual for instructions on managing your files and directories.

Note

A hard disk must be partitioned and formatted before you can use it. Be sure you have performed the procedures described in your operating system manual to prepare your hard disk for use.

Backing up the hard disk

While the hard disk is very reliable, it is essential to back up your hard disk files to diskettes or tapes in case you lose some

data accidentally. Make copies of all your system and

application program diskettes before copying the programs to

the hard disk. Be sure to to back up your data files regularly to keep your backup diskettes or tapes up-to-date.

Curing for your hard disk

Follow these precautions to protect your hard disk drive from damage and to avoid losing data:

Never turn off or reset the computer when the hard disk access light is on. This light indicates that the computer is copying data to or from the hard disk. If you interrupt this process, you can lose data.

Never attempt to open the hard disk drive. The disk itself is enclosed in a sealed container to protect it from dust.

Resetting the Computer

Occasionally, you may want to clear the computer’s current settings or its memory without turning it off. You can do this

by resetting the computer.

For example, if an error occurs and the computer does not respond to your keyboard entries, you can reset it to reload your operating system and try again. However, resetting erases any data in memory that you have not saved; so reset only if necessary.

Caution

Do not reset the computer to exit a program. Some programs

classify and store new data when you exit them in the normal manner. If you reset the computer without properly exiting a program, you may lose data.

To reset the computer, the operating system must be either on the hard disk or on a diskette in drive A; so if you do not have a hard disk, insert the system diskette in drive A. If you are using MS-DOS, hold down and and press The screen goes blank for a moment and then the computer should reload your operating system.

If resetting the computer does not correct the problem, you probably need to turn it off and reboot it. Remove any diskette(s) from the diskette drive(s). Turn off the computer and wait 20 seconds. If you do not have a hard disk, insert the system diskette in drive A. Then turn on the computer.

Changing or Deleting a Password

To change or delete your password, you must run the SETUP program and follow the instructions for entering a password in Chapter 2.

If you do not know your password, see “Password Problems” in Chapter 6.

Changing the Processor Speed

Your computer’s processor can operate at two speeds: fast or slow. Fast speed is the highest speed at which your microprocessor is capable of running, such as 25,33, or 50 MHz. Slow speed simulates an 8 MHz processor to provide compatibility with older application programs.

When your computer is operating at fast speed, the speed light

on the front panel is green. When the computer is operating at slow speed, the light is amber.

You should use fast speed for almost everything you do because your programs will work faster. However, certain

application programs have specific timing requirements and can run only at the slower speed. See your software manual to determine if this is the case.

3-18

Using Your Computer

If you want your computer to always start at slow speed, you can change the default setting through SETUP. See Chapter 2 for instructions.

Some copy-protected programs require the computer to run at

slow speed while accessing the program on a diskette. These programs also usually require you to leave a key disk-the diskette that contains the copy protection-in the diskette drive. If you use a copy-protected program, you can change the speed to slow to access the diskette and return it to fast speed when you are finished.

You can change the processor speed temporarily by entering one of the following commands from the numeric keypad on your keyboard:

To select slow speed, press

To select fast speed, press

(Hold down the key and the key simultaneously

and then press the or key on the numeric keypad.)

Note

You can use the commands listed above while you are running a program. However, if the program uses one of these commands for another function, you cannot use it to change the processor speed. You can, however, enter the command at the MS-DOS command prompt or change it through the SETUP program.

The speed setting remains in effect until you reset the

computer, change the speed with a keyboard command, or change the speed using SETUP.

Installing an Option Card

This section explains how to install an option card in your computer. Your computer has four option slots to accommodate up to four 8-bit or 16-bit 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, follow these guidelines when deciding which slot to use:

If you are installing a display adapter card, make sure any

switches or jumpers on the card are set properly. See the

documentation that came with the card for instructions.

If you installed SIMMs, the bottom slot (slot 1) will accommodate only an 8-bit card.

If you are using a CGA adapter and monitor, you also need to set the Color 80x25 or Color 40x25. See Chapter 2 for instructions on running SETUP.

If you are installing a high-resolution graphics adapter card, follow the instructions below to install the adapter card; then see “Using the VGA Feature Connector” on page 4-17 to connect the card to the VGA feature connector on

Installing a New Processor Chip

You can enhance your 25 MHz or 33 MHz system’s performance by installing an Intel OverDrive processor. Alternatively, for the 25 MHz system, you can install a 487SX microprocessor with a built-in math coprocessor.

An OverDrive processor is a CPU chip which doubles the internal processing speed of the microprocessor and includes a built-in math coprocessor. A math coprocessor is an optional microprocessor for 486SX systems that allows them to perform some mathematical functions faster.

Installing and Removing Options

4-21

Complete instructions for installing the processor are provided

in the manual that comes with it. Please follow those

instructions carefully, along with the following guidelines:

Although the OverDrive processor User’s Guide instructs you to remove the main system board from the computer, this is not necessary. You can leave the board inside the computer case while you install the processor.

Refer to the illustration on page 4-3 to locate the

microprocessor socket on the system board. You can install the OverDrive processor (or 487SX chip) directly in this socket; however, you need to remove the current microprocessor first. To remove the microprocessor chip, follow the instructions in the next section.

When you install an OverDrive processor, you need to change the jumper setting of J4 to position A.

After you install the processor and replace the computer’s

cover, run the SETUP program so your computer can update its configuration. See Chapter 2 for instructions. (You need only run the program and save the configuration; you do not need to change any settings.)

4-22

Installing and Removing Options

Replacing the Processor Chip

If you need to remove the existing microprocessor chip to replace it with a math coprocessor or OverDrive chip, follow these steps:

Use the illustration on page 4-3 to locate the processor socket

1. on the system board.

Caution

Make sure you ground yourself by touching the metal surface on the inside of the computer’s back panel before

you touch the processor chip. Then remain as stationary

as possible while you install it. Do not touch the pins on the processor chip. Handle the processor only by the edges of its case.

If you use a chip puller, position the puller between the

2. processor chip and the socket.

You can also use a small, flat-edged screwdriver instead of a

chip puller. Carefully wedge the tip of the screwdriver

between the processor chip and the socket. Gently turn the screwdriver until the chip begins to separate from the

socket. Move the screwdriver to another side of the

processor chip and again turn it until the chip separates

from the socket. Keep doing this until you can lift the

processor chip straight up from the socket. Gently pull the processsor chip straight up and set it aside.

Remove the replacement chip from its package and inspect
