Important Safety Instructions
Read all of these instructions and save them for later reference.
Follow all warnings and instructions marked on the computer.
Unplug the computer before cleaning. Clean with a damp
cloth only. Do not spill liquid on the computer.
Do not place the computer on an unstable surface or near a
radiator or heat register.
Do not block or cover the openings in the computer’s
cabinet. Do not insert objects through the slots.
Use only the type of power source indicated on the
computer’s label.
Connect all equipment to properly grounded power outlets.
Avoid using outlets on the same circuit as photocopiers or
air control systems that regularly switch on and off.
Do not let the computer’s power cord become damaged or
frayed.
If you use an extension cord with the computer, make sure
the total ampere rating of the devices plugged into the
extension cord does not exceed the cord’s ampere rating.
Also, make sure the total of all devices plugged into the wall
outlet does not exceed 15 amperes.
Except as specifically explained in this User’s Guide, do not
attempt to service the computer yourself.
Unplug the computer and refer servicing to qualified service
personnel under the following conditions:
If the power cord or plug is damaged; if liquid has entered
the computer; if the computer has been dropped or the
cabinet damaged; if the computer does not operate normally
or exhibits a distinct change in performance. Adjust only
those controls that are covered by the operating instructions.

Q If you plan to use the computer in Germany, observe the
following:
To provide adequate short-circuit protection and over-
current protection for this computer, the building
installation must be protected by a 16 Amp circuit breaker.

Introduction
Your new EPSON® computer is a full powered, full featured
system that gives you complete access for all your business and
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 586-class processor and a generous 8MB
of standard memory you can run a vast array of the latest
programs, utilities, and games designed for productivity and
fun.
The system’s state-of-the-art PCI (Peripheral Component
Interconnect) bus architecture enables faster and more efficient
response from your VGA monitor and any PCI devices you may
install, such as PCI option cards and IDE (Integrated Drive
Electronics) devices.
When you’re ready for even more capability, you can expand
your system and video memory, install option cards and
additional drives, and upgrade your processor.
Computer Features
Your computer offers the following features:
3 586-class processor
Ll 8MB of RAM (Random Access Memory), expandable to
128MB
0 PCI components on the main system board provide a direct
line for caching, memory, and device control for all PCI
devices
Introduction 1

High-speed, PCI VGA controller with an integrated 24-bit
RAMDAC and 64-bit DRAM 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)
16KB of internal cache in the processor and 256KB of
external cache on the main system board
1MB of video memory, expandable to 2MB
Three Energy Star compliant power-saving modes for the
CPU, video, and hard disk drives in standard configurations
Three l&bit, ISA (Industry Standard Architecture) option
slots and two PCI option slots supporting up to two PCI bus
master cards
On the slimline computer, space for up to four mass storage
devices-three externally accessible and one internal; on
the tower computer, space for up to seven mass storage
devices-four externally accessible and three internal.
Power-saving Feature
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 “deep
green” feature places 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
deep green feature in the SETUP program.
2 Introduction

ISA and PCI Expansion Buses
Your computer includes two expansion buses for two types of
option cards: ISA and PCI. The ISA bus transfers data at
8.33 MHz for up to three 16-bit ISA option cards. This bus is
especially suitable for fax /modem cards, sound cards, and SCSI
(Small Computer System Interface) cards for scanners.
The PCI bus provides extremely fast data transfer (33 MHz) for
up to two high-performance PCI cards, such as network
adapters and high-speed video cards. The computer supports
Windows 95 plug and play technology that automatically
configures the resources used by Windows 95 compliant
expansion cards, such as interrupt requests and memory
addresses.
System and Video BIOS
The computer’s system and video BIOS are contained in a flash
memory device on the main system board. The BIOS includes
the following:
Q ISA and PCI compatibility
3 Power-on diagnostic tests
Ll SETUP program
Cl PCI auto-configuration utility
3 BIOS upgrade and recovery code.
Your computer supports shadowing of the system and video
BIOS to allow the BIOS routines to run from fast, 64-bit RAM
instead of from the slower, 8-bit flash ROM device.
Introduction 3

Plug and Play Compatibility
Your EPSON computer complies with plug and play industry
standards, which reduce or eliminate manual configuration of
hardware resources. This makes it much easier to add option
cards or peripheral devices to your system.
Also, the system BIOS includes PCI auto-configuration to
support PCI option cards. When you turn on the computer after
installing a PCI option card, the BIOS automatically configures
interrupts, DMA channels, I/O addresses, and other settings.
You can also customize these resources in the BIOS SETUP
program.
MPEG Video Playback Support
Your computer’s video controller supports the Motion Picture
Experts Group (MPEG) compression standard. When you use
software that supports MPEG (for example, a CD-ROM with
moving graphic images) the images approach TV-quality
resolution and full-motion playback speed. This second-
generation video technology is standard on this EPSON
computer and does not require additional hardware or software.
BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can
easily upgrade the BIOS information without replacing the chip.
You can upgrade the BIOS by running a utility from a diskette,
hard disk, or network server.

8 Introduction

Chapter 1
Setting Up Your System
This chapter describes how to set up your computer, if you have
not already done so.
This chapter describes the following procedures:
Ll Choosing a location
3 Setting the voltage selector switch
Ll Connecting system components
Cl Turning the computer on
3 Turning the computer 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 or television, which
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 beginning of this
manual for more information about choosing a suitable
environment for your system.
Also read “Working Comfortably” in Chapter 2 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 115 VAC or 230 VAC.
The computer is shipped with the voltage selector switch set to
115 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 Latin American countries, you will almost
certainly need to reset the voltage selector switch to 230 VAC.
Line source voltages between 200 and 240 VAC are acceptable
with the switch set to 230 VAC.
Caution
Before you turn on the power to your system, make sure the
voltage selector switch 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 right to select 115 VAC or to the left to select 230 VAC.
1-2 Setting Up Your System
