microprocessor
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.

Choosing a Location
When selecting a place to set up your system, choose a safe,
convenient location that provides the following:
q A flat, hard surface. Surfaces like beds and carpets attract
static electricity, which can erase data on your disks,
damage the computer’s circuitry, and prevent proper
ventilation.
q Good air circulation. Leave several inches of space around
the computer so air can move freely.
q Moderate environmental conditions. Select a cool, dry area
and protect your computer from extremes in temperature,
humidity, dust, and smoke. Avoid direct sunlight or other
heat sources.
q No electromagnetic interference. Do not place your system
too close to any electrical device, such as a telephone or
television, which generates an electromagnetic field.
q Appropriate power source. Connect all your equipment
with the appropriate power cords for the power source in
your area. If you are operating the computer in a country
other than the one in which you purchased it, see “Power
Source Requirements” in Appendix A for the cord you
should use.

Connecting a Monitor
If you have a VGA monitor (or a multifrequency monitor with
an analog connector), you can connect it to the computer’s
built-in VGA port as described below. If you have any other
type of monitor (or if you want to install a display adapter card
to control your monitor), see Chapter 4.
1-2
Setting Up Your System
Follow these steps to connect your VGA monitor to the
computer’s built-in VGA port:
1.
Place the monitor and computer so the backs are facing you.
2.
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,
as shown in the following illustration. If your monitor does
not have an attached cable, connect the cable to it now. (See
your monitor manual for instructions.)
3.
Align the connector on the monitor cable with the VIDEO port
on the computer; then insert the connector. Be careful not to
bend the pins when inserting it.

instructions on changing jumper settings and the manual that
came with your monitor for additional information.
2-10
Running the SETUP Program
Setting the Processor Speed
The System speed option lets you set the default speed for
your system. When you select Fast, your system operates at
your processor’s highest speed, such as 25,33, or 50 MHz. The
Slow option simulates an 8 MHz processor to provide
compatibility with older application programs.
At fast speed, your system can access memory faster, so your
programs work faster. Select Fast unless you are using an
application program that requires the slower speed. Check
your program manual.
You can also change the speed temporarily by entering a
keyboard command. See “Changing the Processor Speed” in
Chapter 3 for more information.
Setting the Booting Sequence
The booting sequence determines the order in which the
computer checks the drives when it looks for the operating
system.
For example, if you select A : then C, each time you turn on
the computer it checks drive A for an operating system diskette
and loads the operating system from that diskette. If drive A
does not contain an operating system diskette, the computer
loads the operating system from drive C. This is the default
setting because you may sometimes want to boot the computer
from a system diskette in drive A.
If you select C : only, the computer loads the operating
system from drive C and does not check drive A. This setting
allows the computer to load the operating system a little faster.
Running the SETUP Program
2-11
Setting the Diskette Seek Parameter
If you enable the Diskette seek test option, the system
checks for a diskette drive during its power-on diagnostics. If
no diskette drive is connected, you see a diskette drive error.
Disable this option if you want your system to boot when no
diskette drive is connected.
Using the SETUP Screen Submenus
The SETUP screen contains three submenus that allow you to
change these settings:
q
Shadow ROM options
q
Keyboard options
q
Peripheral options.
To access the options on these submenus, move the cursor to
the Shadow setup,Keyboard setup, or Peripherals
setup parameters. You see a window to the right of the screen
that contains the options for the parameter you have selected.
Press m to move the cursor into the window. Then press
the arrow keys to move the cursor to the option you want to
change. Press
or
to scroll through the available
options.
Setting the Shadow Options
Your computer can access RAM (random access memory) faster
than ROM (read only memory). The Shadow feature on your
system automatically copies the contents of both the system
BIOS and the video BIOS into RAM so your system can
perform certain operations faster.
2-12
Running the SETUP Program
Four additional shadow options allow you to shadow 32KB at
the memory addresses listed on the screen. You may want to
enable one or more of these shadow options if, for example,
you are using option cards that contain ROM. You can shadow
the memory on the card to your system’s RAM using these
options. Check the memory map on page A-6 and the
documentation that came with your option card to determine
which addresses your option card can access. You may also
need to set some switches or jumpers on the option card.

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:
q
1.44MB, 3.5-inch
q
1.2MB, 5.25-inch
q
72OKB, 3.5-inch
q
360KB, 5.25-inch
q
Dual 1.44MB, 3.5-inch and 1.2MB, 5.25-inch.
Using Your Computer

Note
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.
3.5-inch drive/diskette compatibility

If you write to this diskette in a 1.2MB drive, you may not be able to read it
or write to it in a 360KB drive later.
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:
q 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.
q 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.
q 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:
q
A hard disk can store many times more data than a diskette.
q Your computer can perform all hard disk operations faster.
q 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:
q 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.
q Never attempt to open the hard disk drive. The disk itself is
enclosed in a sealed container to protect it from dust.
Using Your Computer

Special Keys on the Keyboard
Certain keys on your keyboard serve special functions when
your computer is running your operating system or application
programs, as described in the table below.
3-14
Using Your Computer
Special key functions (continued)
The
and
key work as toggles; press
the key once to turn on a function and again to turn it off. When
the function is enabled, the corresponding light in the upper
right corner of the keyboard is on.

If these methods do not work, you may need to reset the
computer as described below. Do not turn off the computer to
exit a program or stop a command unless you have to, because
the computer erases any data you did not save.
Using Your Computer
3-15
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.
3-16
Using Your Computer
Using a Password
If you set a system access password when you ran the SETUP
program, you must enter it every time you turn on or reset the
computer. Follow these steps to use your password:
1.
If you do not have a hard disk, insert your system diskette
in drive A.
2.
Turn on or reset the computer. You see the following prompt:
Enter Password:
3.
Type your password and press
After you type the password correctly and press
the
computer loads the operating system and displays the
command prompt.
Note
If you do not know the correct password, see “Password
Problems” in Chapter 6.
Using the Hot Key Feature
Once you set a password, you can keep unauthorized users
from accessing your system by using the hot key feature. This
key combination
the key of your choice)
temporarily locks your keyboard and mouse so you can secure
your system without turning it off.
To use the hot key feature, follow these steps:
1.
See Chapter 2 to set your password and define a hot key.
Using Your Computer
3-17
2.
When you want to disable the keyboard and mouse, enter
your hot key combination. The keyboard and mouse lock
up and do not respond to typed entries or mouse
movement.
3.
To resume activity, type your password and press
.
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:
q To select slow speed, press
q
To select fast speed, press
(Hold down the
and then press the
or
key and the
key simultaneously
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.

Changing the Jumper and DIP Switch Settings
The main system board in your computer has a number of
jumpers and DIP (Dual Inline Package) switches. These devices
control the operation of your system and provide configuration
information to your CMOS ROM.
The jumpers control the following functions:
q
Enable or disable the built-in VGA display adapter
q Specify the type of CPU installed
q Specify the amount of external cache.
The DIP switches control these functions:
q
Specify a color or monochrome monitor
q Specify the type of CPU installed on your system board
q
Enable or disable the password
q Select the processor speed.
Jumpers and DIP switches are preset at the factory to match

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:
q
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.
q
If you installed SIMMs, the bottom slot (slot 1) will
accommodate only an 8-bit card.
q If you are using a CGA adapter and monitor, you also need
to set the Primary display option in SETUP to
Color 80x25 or Color 40x25. See Chapter 2 for
instructions on running SETUP.
q
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
the main system board.
Note
Before you install an option card, see if you need to change
any jumper settings or DIP switches on the system board.
For example, if you install a video card, you may need to
change jumper J3. See page 4-6.
4-14
Installing and Removing Options
Follow these steps to install an option card:
1.
If you are installing a card in the option slot for the first time,
you need to remove the metal cover for that slot on the
inside back panel. Remove the retaining screw securing the
option slot cover to the computer. (Keep the screw to secure
the option card to the computer.)
2.
Slide out the slot cover and set it aside. (Store the slot cover in
a safe place in case you remove the option card later.)
3.
Unpack the option card and adjust any switches or jumpers
on it, if necessary. (Check the option card instructions.)
When you handle the card, do not touch any of the
components on the circuit board or the gold-edged
connectors. If you need to set it down before you install it,
place it gently on top of its original packing material with
the component side facing up. Keep the packing materials
in case you remove the card later.

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:
q 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.
q 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.
q When you install an OverDrive processor, you need to
change the jumper setting of J4 to position A.
q After you install the processor and replace the computer’s
cover, run the SETUP program so your computer can

Setting the Hard Disk Drive Jumpers
Most hard disk drives have jumpers that must be set for the
drive to work properly with the computer. The jumpers tell the
computer whether you are using one hard disk drive or two. If
you purchased your computer with a hard disk drive already
installed, these jumpers have been set correctly for your system.
If you install a hard disk drive in your computer, be sure to
check the drive’s jumper settings before you install it. See the
documentation that came with your drive for the proper
settings, then follow the instuctions below.
If you install a second hard disk drive, you must set the
jumpers on both drives to indicate which drive is the master
(primary) drive and which is the slave (secondary) drive. A
master drive is the drive on which you’ll install the operating
system that the computer loads into its memory each time you
turn it on. You can run application programs and store data on
both the master and slave drive, but the operating system must
be on the master drive.

Error Messages
Your computer’s built-in memory (ROM) contains a series of
diagnostics programs, called power-on diagnostics, which your
computer runs automatically every time you turn it on. These
programs check internal devices such as ROM, RAM, the timer,
the keyboard controller, and the hard disk drive.
When the system detects an error that isn’t serious, such as an
incorrectly defined diskette drive, you see an error message
and the following prompt:
Press <Fl> to run SETUP or <F2> to continue
Write down the error message and press
to continue.
If the system detects a serious error, the computer cancels
further checking and halts system initialization. The error
message remains on the screen and the computer locks up. If
this happens, see “The Computer Won’t Start” in this chapter.
If none of the suggestions listed there solves the problem,
contact the Epson Connection as soon as possible. Report any
error messages when you request technical assistance.

Troubleshooting
6-11
Diskette Problems
If you see an error message or have trouble accessing data on a
diskette, try the following steps:
1. You may have inserted the diskette upside-down or it may
not be inserted all the way. Remove the diskette and
reinsert it. If the diskette drive has a latch, be sure to turn it
down to secure the diskette. See Chapter 3 for detailed
instructions on inserting and removing diskettes.
6-12
2.
If reinserting the diskette does not solve the problem and
you have access to another drive of the same type, place the
diskette in the other drive and repeat the operation. If you
can read the diskette, the trouble may be in your diskette
drive. See “Diskette Drive Problems” below.
3.
Have you inserted the right type of diskette? For example, are
you trying to read a 1.44MB diskette in a 720KB diskette
drive?
4.
Is the diskette write-protected? On a 3.5-inch diskette, the
write-protect switch may be set to the write-protect position
or there may be no switch. On a 5.25-inch diskette, there
may be a write-protect tab over the side notch or there may
be no notch. You cannot alter data on a write-protected
diskette. (Some programs do not function properly if the
diskette is write-protected.) See Chapter 3 for more
information.
5.
Is the diskette formatted? A new diskette must be formatted
before you can store data on it. See your operating system
documentation for instructions on formatting diskettes.
Troubleshooting
6.
Did you receive one of the following MS-DOS error
messages?
Disk Drive Error: Abort, Ignore, Retry?
Disk error reading drive d:
Disk error writing drive d:
If you see one of these messages, make sure the diskette is
properly inserted in the drive. If the problem persists, try
removing the diskette and reinserting it. If the error
message still occurs, you may have a defective diskette. Try
copying the files from the bad diskette to a new diskette.
7.
If you see no error messages but there is something wrong
with the data in a file, the operating system or an
application program may have updated the storage
information on the diskette incorrectly. This is probably the
case if you have one of these problems:
q
Part of a file is missing
q
A file includes parts of other files
q
An expected output file is missing.
If you are using MS-DOS use CHKDSK to make the necessary
repairs; see your MS-DOS documentation for instructions.
You may also have some special diagnostic software you
can use to check your diskettes.
Troubleshooting
6-13
Diskette Drive Problems
If you see a diskette error message or have difficulty with a
diskette drive, follow these steps:
1.
If you have problems with a new diskette drive that someone
else installed, consult that person about the problem.
2.
If you installed the drive yourself, did you carefully follow all
the steps in Chapter 5? Review the instructions and check
all the cable connections to make sure you installed the
drive correctly.
3.
Did you run the SETUP program and configure the correct
type of diskette drive for your system? (See Chapter 2 for
instructions.)
4.
If the diskette drive is making loud or unusual noises, do not
attempt any further examination of it. Contact the Epson
Connection for assistance.
Hard Disk Problems
If you have a problem with a hard disk, it could be the result of
improper installation, incomplete disk preparation, or
corrupted data. Consult one of the following sections:
q Installing the drive
q Preparing the drive for use
q Accessing data on the drive.
Caution
If your hard disk has data on it, always be sure to back up
your data before reformatting or repartitioning the drive.
6-14
Troubleshooting
Installing the Drive
If you have problems with a newly-installed drive, check the
following:
1.
If someone else installed the drive, consult that person about
the problem.
2.
If you installed the hard disk in your computer, did you
carefully follow all the instructions in Chapter 5? Review
the instructions, check all the cable connections, and check
the jumper settings on your drive.
3.
If you installed an IDE hard disk drive, be sure you run
SETUP to update your configuration. Check to make sure
you selected the correct drive type and that you enabled the
built-in IDE hard disk drive controller with the
Peripherals SETUP option in SETUP. (If you connected
the IDE drive to a controller on an option card, be sure you
set the built-in controller to Disabled.) See Chapter 2 for
instructions.
4.
If you installed a non-IDE hard disk drive, was it
physically formatted by the manufacturer? A blank, new
hard disk must be physically formatted (or initialized)
before you can partition it and install an operating system
on it. This type of format is usually done by the
manufacturer; if yours was not, you must do it yourself. If
the drive came with its own format utility, use that
program.
Note that a physical format is different from the softwarebased type of formatting commands (such as the MS-DOS
SELECT or FORMAT commands). See “Preparing the
Drive,” below, for more information.
Troubleshooting
6-15
Preparing the Drive
Before you can store data on a new hard disk (which has
already been physically formatted), you must do the following
to prepare it for use:
1.
Run the SETUP program to define your hard disk as part of
the computer’s configuration. (See Chapter 2 for
instructions.)
2.
Partition and format the drive for your operating system. If
you are using MS-DOS, instructions for performing these
procedures are provided in your MS-DOS manuals. If you
are using another operating system, follow the instructions
that came with it.
If you do not prepare the drive correctly, you cannot store data
on the disk. For example, if you partition the drive and format
it for MS-DOS (or for another operating system) but you do not
copy the operating system to the drive, you will not be able to
load the operating system from the hard disk.
If you are sure the hard disk was installed properly and you
prepared it for use as described above but you cannot access
the drive, review the instructions in your operating system
manuals. Make sure you performed each step in the installation
process correctly for your configuration.
Accessing Data on the Drive
If you have been using your hard disk drive successfully for
some time and notice a reduction in performance, the data on
the disk may have become fragmented. You may want to back
up all your data and then use a disk compaction utility to
reorganize the files on your disk. Many general utility
programs include a disk compaction utility.
6-16
Troubleshooting
If you still have trouble with your hard disk, you can back up
your data and physically reformat the disk. Then you’ll need to
reinstall the operating system and copy your files back onto the
disk. See your operating system manual for instructions.
If you cannot access data on your hard disk or you are
receiving read/write errors, the disk may have a physical
problem. Contact the Epson Connection for assistance.
Software Problems
If you have trouble with an application program, try the
following:
1.
If the application program does not start, check that you are
following the correct procedure for starting the program,
and that it is installed correctly. If you have a hard disk and
the program is stored in a directory on that drive, make
sure you are logged onto or specifying the correct directory.
If you don’t have a hard disk, make sure you inserted the
correct diskette in drive A.
2.
Your computer can run at fast or slow speed. While almost all
programs work properly at the faster speed, some must run
at the slower speed. Check your software manual to see if
this is the case, and change the processor speed if necessary.
See “Changing the Processor Speed” in Chapter 3 for
instructions and information on using copy-protected
programs.
Troubleshooting
6-17
3.
If you entered an MS-DOS command that you want to stop,
there are special key combinations you can use to cancel the
command. These methods may also work in your
application programs:
4.
An application program can occasionally lock the computer,
making it unresponsive to keyboard commands. If your
computer does not respond when you type on the
keyboard, you can reset it. Follow the instructions in
Chapter 3.
5.
If resetting the computer does not help, remove any

Printer Problems
Below are some general steps to follow if you have difficulty
with your printer. If the problem persists and you need more
detailed information, check your printer manual.
You see a port error message if you are having trouble with the
port to which your printer is connected.
1.
If your printer does not work at all, check that the printer
has power and is properly connected to the computer.
(Also, make sure your printer has paper in it.) See
Chapter 1 or your printer manual for instructions.
6-18 Troubleshooting
2.
Check the printer manual for the printer’s correct DIP switch
or control panel settings. These settings help a printer
communicate properly with the computer.
3.
If you are using more than one serial or parallel port, the
computer must know which port is the primary port and
which is the secondary port. See Chapter 2 for instructions
on how to set the parallel and serial ports using the
Peripherals Setup option in SETUP program.
4.
If your printer is properly set up but is still not functioning,
test it from the MS-DOS level. When the screen displays the
MS-DOS command prompt (such as C : \ or A: \), hold
down
and press
This should print the
contents of the screen on your printer.
If it does not, you may need to change the internal setting
of the computer’s parallel port for a parallel printer (or
serial port for a serial printer). To do this, use the MS-DOS
MODE or SETMODE command. See your printer manual
and MS-DOS documentation for more details.
5.
Many application programs (such as word processors) must
be set up properly before they can use a printer. Check your
program manual to see what customizing may be required.
6.
If you are using an application program that requires a
printer driver, make sure the correct driver is installed. See
your application program manual for instructions. Also see
your printer manual for additional instructions on using
your printer with application programs.
Troubleshooting

Option Card Problems
If you install an option card and it does not function properly,
check the following:
1.
Is the option card installed correctly? Make sure it is
well-seated in its slot. Check the installation procedure
described in Chapter 4 and also see the instructions that
came with the card.
2.
Did you set the necessary DIP switches or jumpers on the
option card? See the card’s manual for instructions.
3.
Did you set the necessary jumpers on the main system
board? See Chapter 4 for more information.
4.
Did you run the SETUP program to update your computer’s
configuration after installing the card? See Chapter 2.
5.
If you used the option card to add an external device to
your computer, did you use the proper cable to connect the
device to the card?
6.
Did you perform the correct setup procedures for the
software you are using with the option card? See your
option card or software manual for instructions.
Mouse Problems
If you have trouble with your mouse or you see an auxiliary
device error message, check the following:
1.
6-20
Make sure the mouse cable is securely connected to the
mouse port and not the keyboard port. If you have a serial
mouse, make sure it is securely connected to the correct
serial port. See Chapter 1 for instructions.
Troubleshooting
2.
Did you install the mouse driver correctly? See your software
manual and the documentation that came with your mouse
for instructions. (Windows installs a mouse driver
automatically.)
3.
If you are using a serial mouse, did you disable the built-in
mouse port with SETUP and enable the correct serial port?
See Chapter 2 for instructions.
Memory Module Problems
If you added extra memory to your system by installing SIMMs
and that memory is not operating properly, check the following:
1.
If the memory count displayed by the power-on diagnostics
program is incorrect, you may not have installed the
SIMMs correctly. They may be the wrong type of SIMM or
they may not be inserted all the way.
See “Memory Modules (SIMMs)” in Chapter 4 and make sure
you followed all the instructions.
2.
Be sure to run the SETUP program after you install or
remove memory modules to automatically update your
memory configuration. See Chapter 2 for instructions.
3.
If you still have trouble with your SIMMs, write down any
error messages that appear and contact the Epson
Connection for assistance.
Troubleshooting
6-21
External Cache Problems
If you added extra cache memory to your system by having
cache DIP chips installed, and that memory is not operating
properly, check the following:
1.
If the cache memory amount displayed by the power-on
diagnostics program is incorrect, your Authorized Epson
Servicer may not have installed the cache correctly. Call
your servicer to describe the problem.
2. Did the servicer set jumpers J5 through J9 to indicate the new
amount of cache? Check the jumpers to see if they are set
correctly. See “Changing the Jumper and DIP Switch
Settings” in Chapter 4 for instructions.
3.
If you still have trouble with your external cache, write down
any error messages that appear and contact the Epson
Connection for assistance.
Battery Problems
The battery in your computer is a 3.6 volt, lithium battery. It
should last from three to five years before you need to replace
it. When the batterys life has expired, you may see one of the
following error messages:
CMOS battery state low
