EPSON® User’s Guide Update

In order to take advantage of the latest technology, the system board in your computer has been completely redesigned.

This update includes last-minute information that was not available at the time your on-screen User’s Guide was created.

Extenal Cache

Your computer supports up to 1MB of external cache. If your system already has cache installed, it can be increased up to 1MB. However, you cannot install cache chips yourself. Please contact your

Authorized EPSON Servicer if you want to install cache memory in your computer.

Power Management

The Windows®95 CD-ROM Autoplay feature operates continuously and prevents power management from being fully effective on your system. If you want to take advantage of your computer’s power-

saving features, you must use the Widows Device Manager to

disable Autoplay. See your Windows documentation for instructions.

System Board

Because your computer’s system board has been redesigned, the illustrations showing the board in Chapter 4 of your User’s Guide are incorrect. Board components such as jumpers and SIMM sockets have been relocated. However, disk drives and other internal components are shown correctly in the illustrations.

The illustration below shows the correct location of jumpers and other components on the system board in your computer.

Jumper Settings

The jumpers on the system board have been renumbered, as shown in the tables below. The factory default settings are indicated by an asterisk (*).

Introduction

Your new EPSON® computer is a full powered, full featured system that gives you complete access for all your business or home computer needs. And because your computer is plug and play compliant and designed to take advantage of Microsoft Windows®95, you’ll be able to use all the latest technology.

With the computer’s high-performance processor and memory you can run a vast array of the latest programs, utilities, and games designed for productivity and fun.

Your system’s state-of-the art PCI (Peripheral Component Interconnect) bus architecture gives you fast and efficient access to both PCI and IDE option cards. It also provides PCI performance for IDE drives and your VGA or high-resolution monitor.

And when you’re ready for even more capability, you can expand your system, video, and cache memory, install option cards or additional drives, and upgrade your processor.

Computer Features

Your computer offers the following features:

Upgradable 486-class processor

4 or 8MB of RAM (Random Access Memory), expandable to 128MB

PCI-based main system board providing PCI caching, memory, bus control, video control, and IDE (Integrated Drive Electronics) device control

Introduction

High-speed, PCI video controller with 64-bit DRAM video interface and 32-bit CPU interface

Two PCI ATA-2 compatible, enhanced IDE interfaces supporting up to four IDE devices, such as hard disk drives and CD-ROM drives (two on each interface)

8 or 16KB of internal cache in the processor and up to 512KB of external cache on the main system board

1MB of on board video memory for resolutions up to 1024 x 768; memory expandable to 2MB

Three Energy Star compliant power-saving modes for the CPU, video, and hard disk drives in standard configurations

Three 16-bit, ISA (Industry Standard Architecture) option slots and two PCI option slots supporting up to two PCI bus m aster cards

On the slim line model, space for up to four mass storage devices, three externally accessible and one internal; on the tower model, space for up to seven mass storage devices, four externally accessible and three internal.

Power-saving Features

In standard configurations, this computer complies with the United States Environmental Protection Agency’s Energy Star Program, which promotes the manufacture of energy-efficient printers, computers, and monitors. Your computer’s “Green PC” features place the CPU, video, and hard disk drives in power-saving modes when the mouse and keyboard have been inactive for a specified period of time. You can customize the Green PC features in the SETUP program.

2 Introduction

ISA and PCI Expansion Buses

Your computer includes expansion buses for two types of option cards: ISA and PCI. The PCI bus provides extremely fast data transfer (33 MHz) for up to two high-performance PCI cards, such as high-speed video cards. PCI cards use plug and play technology that automatically configures resources used by the card, such as interrupt requests and memory addresses.

The ISA bus transfers data at 8.33 MHz for up to three 16-bit ISA option cards. You can use these slots for standard ISA cards such as fax/ modem cards, sound cards, and SCSI (Small Computer System Interface) cards.

System and video BIOS

The computer’s system and video BIOS are contained in a flash memory device on the main system board, which you can upgrade without replacing the chip.

Your computer supports shadowing of the system and video BIOS to allow BIOS routines to run from fast, 32-bit RAM instead of from the slower, S-bit flash device.

Chapter 1

Setting Up Your System

This chapter briefly describes how to set up your computer if you didn’t set it up already using the information in your

User's Digest. It includes the following information:

Choosing a location

Setting the voltage selector switch

Connecting system components

Turning the computer on and off.

Choosing a Location

Before you set up your system, choose a convenient location that provides a flat, hard surface. Do not place your system too close to any electrical device, such as a radio, that generates an electromagnetic field. Protect your computer from extremes in temperature, humidity, dust, and smoke, and avoid direct

sunlight or other sources of heat.

Read the “Important Safety Instructions” at the front of this manual for more information about choosing a suitable environment for your system.

Also read “Working Comfortably” in Chapter 3 for guidelines on creating a comfortable and safe working environment.

Setting Up Your System

1-1

Setting the Voltage Selector Switch

Your system is powered by a 200 Watt power supply. The power supply input voltage is controlled by a switch on the computer’s back panel that may be set to 110 VAC or 220 VAC. (The switch on your computer may read 115 VAC or 230 VAC; these are equivalent settings.)

The computer is shipped with the voltage selector switch set to 110 VAC, which is appropriate for line source voltages between 100 and 120 VAC. This is generally the correct setting if you use the computer in North America, South America, or Japan.

If you plan to operate the computer in the United Kingdom,

Europe, or some South American countries, you will almost certainly need to reset the voltage selector switch to 220 VAC. Line source voltages between 200 and 240 VAC are acceptable with the switch set to 220 VAC.

Caution

Before you turn on the power to your system, make sure the

voltage selector is set appropriately for the electrical power

source in your location or you will seriously damage your

system.

To change the voltage selector switch setting, slide the switch to the left to select 110 VAC or to the right to select 220 VAC.

1-4 Setting Up Your System

There should be two cables provided with your monitor: the monitor cable (to connect it to the computer) and the power cable (to connect it to a power source). On most monitors, the monitor cable is permanently attached to the monitor. If your monitor does not have an attached cable, connect the cable to it now.

Examine the connector on the monitor cable and line it up with the monitor port on the computer. Then insert the connector into the port.

This icon identifies the SVGA monitor port.

Caution

To avoid damaging the connector, be careful not to bend the pins when you insert it.

If the connector has retaining screws, tighten them.

Plug the monitor’s power cord into the power inlet on the back of the monitor.

Plug the other end of the power cord into a grounded electrical outlet or into the power outlet on the back of the computer. Note that the position of the power inlet and AC outlet on your computer may be reversed.

Caution

Before you plug the monitor’s power cord into the back of your computer, make sure the monitor’s power requirements do not exceed 2 Amps at 115 volts and

1 Amp at 220 volts.

Setting Up Your System 1-5

Connecting a Parallel or Serial Device

Your computer has one multi-mode parallel (printer) port and two serial ports. To connect a printer or other peripheral device, refer to the illustrations under “Connecting System Components” as you follow the appropriate instructions in this section.

Using the parallel (printer) port

Follow these steps to connect a parallel device to your computer:

Place the parallel device and the computer so that the backs are facing you.

Align the connector end of the parallel cable with the printer port and plug it in. If the connector has retaining screws, tighten them.

This icon identifies the printer port.

Connect the other end of the cable to the parallel device. To secure the cable, squeeze the clips at each side of the device port and push them into place.

Plug the parallel device’s power cord into a grounded electrical outlet.

If you want to take advantage of the port’s extended capabilities, see “Using the Advanced System Setup Options” in Chapter 2.

1-6

Setting Up Your System

Note

If you use ECP mode (Extended Capabilities Port), check your parallel device software documentation for the correct DMA channel (DRQ) setting. Then set jumpers JP8 and JP18 to match this setting if necessary. See “Changing the Jumper

Settings” in Chapter 4 for more information.

Using the serial ports

If you have a printer, a modem, or other device with a serial interface, you can connect it to one of the serial (RS-232C) ports. Make sure you have a cable compatible with a DB-9P connector.

To connect a serial device, insert the connector into either of the two serial ports, which are marked with

the icons shown at the left. If you are connecting only

one serial device, use the serial 1 port.

Connecting the Power Cord

Follow these steps to connect the computer’s power cord:

Plug the power cord into the power inlet on the back of the computer. Note that the position of the power inlet and AC outlet on your computer may be reversed.

Chapter2

Running SETUP and Installing Drivers

If you’ve added options or you want to customize your computer, you can use a configuration program called SETUP, which is contained within the BIOS on the system board.

SETUP allows you to change the settings for your hardware configuration, security options, and power-saving features. The configuration information you enter is stored in the computer’s ROM (read-only memory) and is backed up by a battery, so it is not erased when you turn off or reset your computer.

You may also want to install drivers and utilities for the built-in PCI IDE interfaces and the built-in PCI local bus video

interface. You only need to install these drivers if you’re using

an operating system other than Windows.

2-14 Running SETUP and Installing Drivers

Using the virus protection features

The Diskette access option allows you to restrict access to your diskette drives based on the password levels you have defined. This prevents unauthorized users from accessing the drives and possibly introducing a virus to your system. You can restrict diskette access only if passwords are enabled and you have enabled the Password on boot option.

If you select Supervisor for this option (the default setting), you can access the diskette drives only if you enter the

Supervisor password when you start your system. Users who start the system with a User password, however, will see an error message when they try to access the diskette drive. If you select User for the Diskette access option, you can access the diskette drives whether you enter the Supervisor or User password when you start the system.

Note

To use passwords for diskette drive access, you must enable

the Password on boot option. If you select a password

level for Diskette access, but leave the Password on boot option disabled, you see an error message

whenever you try to access your diskette drive.

You can also protect your system by selecting Write

protect for the Fixed disk boot sector option.

When this option is enabled, the system displays an error message when a program tries to write to the boot sector of your hard disk drive. To use a program designed to write to the boot sector (such as the Format command), you must selecct

Novell NetWare versions 4.0 and higher (4.0X).

Before you install the PCI IDE drivers, make sure you back up your hard disk drive. Then use the installation program on the PCI IDE drivers diskette to install the drivers.

Note

Make sure you use the installation program to install the PCI IDE drivers. If you simply copy the driver files, they won’t work correctly.

The driver files for each of the programs listed above are in their own directory on the diskette. Log onto the directory for each driver you want to install and print out the README file. Refer to the information in these files for additional instructions on installing and using the PCI IDE drivers.

Using a password.

Working Comfortably

If you spend a lot of time at your computer, you may experience occasional fatigue or discomfort caused by repetitive motions or too much time spent in one position. If

you follow the guidelines in this section, you may avoid these

problems and actually increase your productivity.

Using Your Computer

3-1

Take a few minutes to read this section for suggestions about:

Using the right furniture

Positioning your monitor

Lighting your workspace

Using a keyboard and mouse

Maintaining good posture and work habits.

Using the Right Furniture

Selecting a good desk and using the right type of chair can make a big difference in your level of comfort. When you set up your furniture, consider these suggestions:

An L- or U-shaped desk configuration works well because it provides ample space to hold your computer equipment and work materials while keeping everything within easy reach. A split-level desk or one with a pull-out keyboard drawer lets

you place the keyboard in a comfortable typing position.

Since you’ll usually be sitting when you use your computer, it’s important to have a good chair. An adjustable chair allows you

to support your body in the correct position. Make sure the

chair supports your lower back; the backrest should fit the

curvature of your spine. To reduce fatigue, try to use a chair with adjustable, padded armrests so you can occasionally rest your arms while you work.

Make sure the seat and backrest are wide enough so you can sit

in a variety of positions throughout the day. Also leave enough room under the work surface so you can vary the position of your legs.

3-2 Using Your Computer

Adjust the height of your chair so when you are using the keyboard or mouse your upper arms are vertical and your forearms and wrists are horizontal. For good circulation, your feet should rest flat on the floor with your lower legs vertical and your knees level with your hips. You may need to use a footrest to maintain the correct alignment for your legs.

Positioning Your Monitor

Place the monitor so it is directly in front of you

with the top of the screen slightly below eye level when you are sitting at the computer. You may want to place it on top of the computer or on a stand.

Your line of sight to the screen should be about 10 to 20 degrees below the horizontal. If the monitor has a tilt and swivel base, you can adjust the position of the screen for the best viewing

angle.

Sit about an arm’s length or more away from the monitor. The

most comfortable viewing distance depends on the size of the

screen characters and your ability to focus on the display.

Adjust the monitor’s brightness and contrast controls to maximize image clarity, and keep the screen clean.

Try placing any source documents you are using on a copy

stand and position the stand next to the screen at the same eye level. This reduces neck strain and makes it easier for your eyes to move back and forth between the document and the screen.

Using Your Computer 3-3

Lighting Your Workspace

Appropriate lighting increases your comfort and productivity, and it’s good for your eyes.

Arrange your computer and light sources to minimize glare

and bright reflections.

Position the monitor so that any windows in the room face the sides of the monitor, not the front or back. This will help reduce

glare.

For working at the computer, indirect or shielded lighting is best, and it should light your entire office equally. Make sure the lighting is not too bright, because this can make your eyes tired from continually readjusting between the relative dimness

of the screen and the bright surroundings. You can use window blinds, shades, or drapes to control the amount of daylight in the room or reduce overhead lighting by turning off or

dimming the lights.

Here is a simple way you can test your lighting. While looking

at the screen, use your hand to shield your eyes from the brightest light source in the room (such as a window or

overhead light). If you feel a sense of relief, no matter how

small, your current lighting is too bright.

Using the Keyboard and Mouse

Constant use of a keyboard, mouse, or any pointing device can lead to a variety of aches and strains. To prevent injury, keep your hands

relaxed and rest them frequently.

Try to keep your fingers parallel with your forearms to prevent

straining your wrists. Adjust the angle of the keyboard so the

slope is no more than 25 degrees. (The keyboard has legs on the bottom which allow you to adjust the angle.)

3-4 Using Your Computer

Keep your hands and fingers relaxed when you are typing and try not to press the keys too hard; using too much force creates tension in your hands. Remove your hands from the keyboard when you are not using it and take frequent breaks to stretch your hands and fingers.

When using a mouse, keep your wrist and fingers relaxed. Let go of the mouse frequently and stretch or relax your hand. Leave enough space on your work surface so you can freely move the mouse.

Maintaining Good Posture and Work Habits

Here are suggestions to help you stay fit while

using your computer. If you form good work habits, you shouldn’t have to spend too much time thinking about it!

Work in a relaxed, natural, upright position and let the chair support you. Your back and neck should be straight with your shoulders down and relaxed. Keep the elbows and hips bent at about a 90 degree angle and your forearms and thighs parallel to the floor.

Try to keep your arms in an easy, natural position with your elbows near your body and level with or slightly lower than the keyboard. Your wrists should be straight, not bent, and your hands should rest lightly on the keys or the mouse.

Rest your eyes occasionally by closing them or focusing on a fixed spot in the distance.

Change your sitting position frequently throughout the day to avoid muscle fatigue. Take periodic breaks; stand up, stretch, and move around.

Using Your Computer 3-5

Backing Up Your Files

To protect your data, it is a good idea to back up your files regularly. You should also make backup copies of any diskettes

you have that contain programs (your system may have come

with a utility installed on the hard disk drive to do this for you) and store the copies away from your originals.

You can use any backup program or the backup utility in your operating system. Read the online help or the software documentation for instructions.

Using Energy Wisely

By purchasing this low-power, Energy Star compliant computer, you join a growing number

of users concerned about conserving energy. Here are a few

additional tips you can use to be even more energy-wise:

If your printer and monitor aren’t Energy Star compliant, turn them off when you’re not using them.

Use the print preview option on your software before you print something. You’ll be able to catch formatting errors before you commit them to paper.

If you have an electronic mail system available to you, send E-mail rather than memos. Not only is this faster, but you’ll save paper and storage space too.

Use recycled paper whenever you can and, if possible, reuse or recycle used paper instead ofthrowing it away.

3-6 Using Your Computer

Using Your Green PC Features

Your computer includes features that lower the power usage of the microprocessor and other components when the system has been inactive for a selected period of time. Using the SETUP program, you can customize inactivity timers for three power-saving modes: Doze, Standby, and Suspend. Each of the three modes provides progressively increased levels of power conservation.

You can also customize an individual Standby timer for the hard disk drive. If you have an Energy Star compliant monitor, your computer places the monitor in power-saving modes too. See “Using the Green PC Features” in Chapter 2 for information on customizing these options.

The power-saving operations performed by your computer in each of the power-saving modes are summarized in the table below.

Power-saving modes

Mode Doze Standby

(disabled by

default)

Suspend

I I

Power-saving operations The processor slows down The processor speed slows further and the monitor

screen goes blank (the monitor is placed in a low power consumption mode only if it is Energy Star compliant)

The processor clock stops, the hard disk drive(s) power down, and the monitor screen goes blank (the monitor is placed in a low power consumption mode only if it is

Energy Star compliant)

Note

Some processors do not support power-saving modes; in these cases only the hard disk drive and monitor can take advantage of your green PC features.

Using Your Computer 3-7

To resume activity when your system is in a power-saving mode, press a key or move the mouse. If your system was in Doze mode, the monitor immediately displays and you can access your system right away.

If your system was in Suspend mode, it takes a few moments for the monitor to display and for the hard disk drive to return to active mode. You'll hear it start again. It takes a few seconds for the drive to reach its full operating speed and read or write to the disk

Note

Some hard disk drives do not support low-power modes.

Also, the delay caused by the hard disk drive returning to

active mode may cause errors in some applications. If you

have problems, you may want to disable the standby timer

for the hard disk drive.

Inserting and Removing Diskettes

To insert a diskette into a 35-inch drive, hold the diskette with

Installing an Option Card

This section explains how to install option cards in your computer. Your computer has five slots; the three large slots

are ISA compatible, and two smaller slots are PCI compatible.

Note

The two PCI slots are identified as PCI1 and PCI2 on the option slot connector card. The computer’s SETUP program refers to the slot number as it configures PCI cards, so note the slot you use for each card you install.

The slot nearest the system board accommodates only a half-length card. On the slimline computer, the slots facing the power supply also accommodate only half-length cards.

Caution

Before you install any option cards in your system, make sure that each card does not draw more current than the limits listed in Appendix A.

4-20 Installing and Removing Options

As you install option cards, keep these guidelines in mind:

Make sure you know whether the card you are installing is an ISA card or a PCI card, so you can install it in the correct type of slot.

If you have an S-bit ISA card, you can install it in a 16-bit ISA slot, as long as it fits.

Check the components on your card and the system board before deciding which slot to use. Make sure that no components are touching or obstructing other cards or cables.

When you unpack the option card, do not touch the components on the circuit board or the gold-edged connectors. Place the card gently on top of its original packing material with the component side facing up. Keep the packing materials in case you remove it later.

Adjust any switches or jumpers on the card, if necessary, before you install it. (See the option card instructions.) Also,

see if you need to change any jumpers on the system board, as described under “Changing the Jumper Settings.”
