Chapter 1
Using Your Computer
This chapter briefly describes the following procedures for
using your computer:
Q Copying the Reference and Utility diskette files
CI Using special keys on the keyboard
LI Stopping a command or program
0 Resetting the computer
Q Using a password
0 Using disks and disk drives
LI Preparing a hard disk for moving.
These instructions assume you have already installed the
operating system on your computer according to the
instructions in your operating system manuals.
Copying the Reference and Utility Files
If you have a hard disk, you’ll probably want to copy some of
the files on your Reference and Utility diskettes to the hard disk
for convenience. This allows you to run the programs any time
without having to insert a diskette. Copy the following files
from the Reference diskette to your hard disk:
CORFIX.EXE
ESPEED.EXE
HDSIT.COM
HDSIT.VER
(Chapter 2 and Appendix B explain how to use these programs.)
Using Your Computer
1-1
The Reference diskette also contains files for the System
diagnostics program. Because you should always run this
program from the Reference diskette, do not copy these files to
your hard disk.
The Utility diskettes contain VGA drivers that allow you to
display graphics in certain high-resolution modes. If you want
to use any of these extended modes on your VGA monitor,
copy any VGA files you need to your hard disk. See the
VGA Utilities Guide for instructions.
Note
Be sure to make backup copies of your Reference and Utility
diskettes.
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.

Using Your Computer
1-3
The [Qpllodrl, [=I, and [s#d] keys 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 comer of the keyboard is on.
Stopping a Command or Program
You may sometimes need to stop a command or program while
it is running. If you have entered an MS-DOS command that
you want to stop, try one of the following commands:
0 Hold down the [cbll key and press [cl
CI Hold down the [cbll key and press m.
These methods may also work in your application program. If
not, you may need to reset the computer as described below.
Caution
Do not turn off the computer to stop a program or command
because the computer erases any data you did not save.
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.
1-4
Using Your Computer
Caution
Do not reset the computer as a means 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.
There are two ways to reset the computer:
0 If you are using MS-DOS, hold down a and m and
press the cd
DCW key. The screen goes blank for a moment
and then the computer should reload MS-DOS. If it doesn’t,
try the next method.
0 Press the RESET button on the front panel. This method
works even when the computer does not respond to your
keyboard entries.
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 five seconds. If you do not have a hard disk, insert the
system diskette in drive A. Then turn on the computer.
Using Your Computer
1-5
Using a Power-on Password
If you set a power-on 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 the computer or press RESET. After the computer
completes its memory test, the screen displays the
following prompt:
Enter Password :
3. Type your password at the prompt. The screen does not
display the characters you type. Then press [Entwl.
After you type the password correctly and press I, you see
the Press <Del> to start SETUP prompt. If you do not
press m, the computer loads your operating system and
displays the command prompt.
If you do not enter the correct password the first time, press
EM and try again.
c5
Note
If you turned on network server mode when you ran the
SETUP program, see “Using Your Computer as a Network
Server” in Chapter 2 for instructions on using the power-on
password.
If you want to change or delete your current password,
you must run the SETUP program. See Chapter 2 of the
Setup Guide for instructions. If you do not know the correct
password, see “Password Problems” in Appendix C.

Using Your Computer
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
explains how disks work and tells you how to:
Use different types of diskettes and diskette drives
Care for your diskettes and diskette drives
Write-protect diskettes
Use a single diskette drive system
Insert and remove diskettes
Format diskettes
Make backup copies
Use a hard disk drive.
How Disks Store Data
Diskettes are made of flexible plastic coated with magnetic
material. This plastic is enclosed in a square jacket that is either
slightly flexible (5¼-inch diskette) or hard (3½-inch diskette).
Unlike a diskette, a hard disk is rigid and fixed in place. It is
sealed in a protective case to keep it free of dust and dirt. A
hard disk stores data the same way that a diskette does, but it
works much faster and has a much larger storage capacity.
All disks are divided into data storage compartments by sides,
tracks, and sectors. Double-sided diskettes store data on both
sides. On each side are concentric rings, called tracks, on which
a disk can store data.
Using Your Computer
1-7
A disk is further divided by sectors, which can be visualized as
pie slices. The figure below provides a simple representation of
tracks and sectors.
Double-sided, double-density diskettes have either 40 or 80
tracks on each side, and double-sided, high-density diskettes
have 80 tracks on each side. Diskettes can have 8,9,15, or 18
sectors per track.
A hard disk consists of two or more platters stacked on top of
one another and thus has four or more sides. In addition, a hard
disk has many more tracks per side than a diskette, but the
number of tracks depends on the capacity of the hard disk. The
number of sectors depends on the type of hard disk.
1-8
Using Your Computer
Your computer uses the read/write heads in a disk drive to
store and retrieve data on a disk. To write to a disk, the
computer spins it in the drive to position the disk so that the
area where the data is to be written is under the read/write
head. A diskette has an exposed area where the read/write
head can access it.
Because data is stored magnetically, you can retrieve it, record
over it, and erase it just as you play, record, and erase music on
a cassette tape.
Types of Diskette Drives
The following list describes the four types of diskette drives
you can use in your computer and which diskettes to use with
them:
Q 1.44MB drive-Use 3½-inch, double-sided, highdensity,
135 TPI (tracks per inch), 1.44MB diskettes. These diskettes
contain 80 tracks per side, 18 sectors per track, and hold up
to 1.44MB of information (approximately 600 pages of text).
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.
0 1.2MB drive-Use 5¼-inch, double-sided, high-density, 96
TPI, 1.2MB diskettes. These diskettes contain 80 tracks per
side, 15 sectors per track, and hold up to 1.2MB of
information (approximately 500 pages of text).
Using Your Computer
1-9
0 720KB drive-Use 3½-inch, double-sided, doubledensity,
135 TPI, 720KB diskettes. These diskettes contain 80 tracks
per side, 9 sectors per track, and hold up to 720KB of
information (approximately 300 pages of text).
Cl 360KB drive-Use 5¼-inch, double-sided, doubledensity,
48 TPI, 360KB diskettes. (You can also use single-sided,
160KB or 180KB diskettes.) These diskettes contain 40
tracks per side and 8 or 9 sectors per track. With 8 sectors
per track, a diskette holds up to 320KB. With 9 sectors per
track, a diskette holds up to 360KB of information
(approximately 150 pages of text).
Note
You must format a new diskette before you can store data on
it. See “Formatting Diskettes,” later in this section.
Drive and diskette incompatibilities
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.
Because of the type and size differences, you cannot use a
3M-inch diskette in a 5%inch drive or vice versa. There are
also limitations on using diskettes that are the same size as the
drive but have different capacities. The following tables
summarize the possibilities and limitations.

information appears on the manufacturer’s label.)
If you have any combination of the above drives (1.44 MB,
1.2MB, 720KB, or 360KB) and you are using MS-DOS, you can
copy files from one drive to another-using COPY or
XCOPY-as long as the correct diskette type is in each drive.
You can also use these commands to copy files between a hard
disk and any type of diskette. However, you cannot use the
MS-DOS DISKCOPY command to copy from one diskette drive
to another if the two drives are not the same type. For more
about copying files and diskettes, see your MS-DOS or other
operating system manuals.

Caring for Diskettes and Diskette Drives
Follow these basic precautions to protect your diskettes and
avoid losing data:
1-12
a
If you have a diskette that contains data you don’t want to
accidentally write over or erase, be sure you write-protect
it. This is especially important for your operating system
and application program diskettes. See “Write-protecting
Diskettes,” below, for more details.
a
Do not remove a diskette from the diskette drive or reset or
turn off the computer while the drive light is on. This light
indicates that the computer is copying data to or from a
diskette. If you interrupt this process, you can destroy data.
cl
Remove all diskettes before you turn off the computer.
a
Keep diskettes away from dust and dirt. Small particles of
dust or dirt can scratch the magnetic surface, destroy data,
and ruin the read/write heads in a diskette drive.
a
Never wipe, brush, or try to clean diskettes in any way.
a
Keep diskettes in a moderate environment. Don’t leave
diskettes sitting in the sun or in extreme cold or heat.
a
Keep diskettes away from magnetic fields, such as electrical
appliances, telephones, and loudspeakers. (Diskettes store
information magnetically.)
a
Do not place diskettes on top of your monitor or near an
external hard disk drive.
cl
Always hold a 5%inch diskette by its protective jacket and
never touch the magnetic surface (exposed by the
read/write slot). The oils on your fingertips can damage it.
Using Your Computer
Q Do not place anything on top of your diskettes, and be sure
they do not get bent.
D Carefully label your diskettes and indicate the type and
density. Attach the label only along the top of a diskette
(next to the manufacturer’s label). Do not stick several
labels on top of one another; this can make it difficult to
insert and remove the diskette in the drive.
P Write on a diskette label before you attach it to the diskette.
If you need to write on a label that is already on the
diskette, use only a soft-tip pen-not a ballpoint pen or a
pencil.
Q Store diskettes in their protective envelopes and in a proper
location, such as a diskette container. Do not store diskettes
flat or stack them on top of each other.
Using Your Computer
1-13
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.
To write-protect a 5¼-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 5¼-inch diskettes.
+]I
0
-notch
l
To remove the write protection, peel off the write-protect tab.
1-14
Using Your Computer
On a 3½-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 3½-inch diskette, slide the
switch toward the edge of the diskette until it clicks into
position, exposing a hole in the comer.
To remove the write protection, slide the switch toward the
center of the diskette until it clicks into position and the hole is
covered.
Note
Some program diskettes have no notch or switch so they are
permanently write-protected. This protects them from being
accidentally erased or altered.
Using Your Computer
1-15
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 require 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,” above.
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 (the Startup diskette, for example) 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.
1-16
Using Your Computer
Inserting and Removing Diskettes
If you have a 5¼-inch diskette drive, insert a diskette as
follows: hold the diskette with the label facing up and the
read/write slot leading into the drive, as shown below.
Slide the diskette all the way into the slot. Then turn the latch
down to lock it in a vertical position. This keeps the diskette in
place and enables the read/write heads in the drive to access
the diskette.
When you want to remove a diskette, first make sure the disk
drive light is off. Then flip up the latch and carefully pull out
the diskette. Place it in its protective envelope and store it in a
proper location, such as a diskette container.
Using Your Computer
1-17
If you have a 3½-inch diskette drive, insert 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.
When you want to remove the diskette, make sure the drive
light is off; then press the release button. When the diskette
pops out, remove it and store it properly.
1-18
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, Reference,
and Utility 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.
Using Your Computer
1-19
Using a Hard Disk Drive
Using a hard disk is similar to using a diskette. However, the
hard disk provides several advantages:
a A 40MB hard disk can store as much data as approximately
thirty-three 1.2MB diskettes, and a 100MB hard disk can
store as much data as approximately eighty-two 1.2MB
diskettes.
a Your computer can perform all disk-related operations
faster.
a 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.
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.
1-20
Using Your Computer
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 alI your system and
application program diskettes before copying the programs to
the hard disk. After you create data files on the hard disk, be
sure to copy them whenever you revise them to keep your
backup diskettes or tapes up-to-date.
Caring 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.
Before you move your computer even a short distance, you
may need to run the HDSIT program to prepare the hard
disk for moving, as described below.
Preparing the hard disk for moving
If you need to move your computer to a new location, you may
want to run the HDSIT program provided on your Reference
diskette to protect the hard disk during the move.
HDSIT moves (or parks) the disk drive’s read/write heads to a
region on the disk surface that does not contain data, and locks
them securely in position. This protects the hard disk from
being damaged if the computer is bumped accidentally.
Using Your Computer
1-21
Many hard disk drives, including all Epson drives,
automatically park their heads when you turn off the
computer. If your hard disk drive does not do this, or if you are
not sure that it does, be sure to run HDSIT.
Follow these steps to run HDSIT:
1. If you copied the HDSIT.COM and HDSIT.VER files to your
hard disk, log onto the directory where they are stored. If
you did not copy the files to the hard disk, insert the
Reference diskette in drive A. Then type A : and press
@El to log onto that drive.
2.
Type
HDSIT
and press [Ent#I
You see a message on the screen that telIs you the disk drive’s
read/write heads will remain locked until you reset the
computer or turn the power off and on again. The computer
locks the heads and disables the keyboard. Remove any
diskettes and turn off the computer. You are now ready to
move it to the new location.

Enhancing System Operations
This chapter tells you how to use the following procedures to
enhance the operation of your computer:
Q Using AUTOEXEC.BAT and other batch files
0 Changing the processor speed
0 Using your computer as a network server
0 Using special VGA features.
Using AUTOEXEC.BAT and Other Batch Files
If you are using MS-DOS to access your application programs,
you may find that there are commands you need to run
frequently. You can automate the execution of these commands
by listing them in a special file called a batch file. When you
type the name of the batch file and press [Enbrl, MS-DOS
executes the commands in the file just as if you had typed each
command from the keyboard.
If you have a word processing program that can save a file as a
text-only file (sometimes called an ASCII file), you can use it to
create a batch file. You can also use the MS-DOS COPY, EDIT,
or EDLIN command, or a text editor, to create the file.
One batch file that you may find particularly useful is called
AUTOEXEC.BAT. Every time you turn on your computer,
MS-DOS looks for the AUTOEXEC.BAT file and automatically
executes each of the commands in the file.
Enhancing System Operations
2-1
When you install MS-DOS, it creates an AUTOEXEC.BAT file
for you, which you can modify or replace as described above.
Be sure to name the file AUTOEXEC.BAT and store it in the
root directory of the hard disk or diskette from which you load
MS-DOS.
See your MS-DOS manuals for more information about creating
and using batch files.
Changing the Processor Speed
Your computer’s processor can operate at two speeds: fast
(33 MHz) and slow (simulated 11 MHz). At fast speed, the
computer can access memory faster. This is the default setting
unless you change the speed to slow with SETUP or the
ESPEED program or set it to change automatically.
Note
When your computer is operating at fast speed, the TURBO
light on the front panel is on. It is off when the computer is
operating at slow speed.
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.
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 one
that contains the copy protection-in the drive. If you use a
copy-protected program often, you may want to set your
processor speed to change automatically to slow speed when
accessing the diskette and return to fast when it is finished.
2-2
Enhancing System Operations
Depending on the type of program you have, you may or may
not want to set the processor to auto speed. Follow these
guidelines:
0 If you are using a copy-protected program that can run
only on a diskette or that requires a key disk, try to load the
program at fast speed. If this works, you do not need to set
the speed to change automatically. If you can’t load the
program at fast, set the speed to change automatically.
Q If you are using a copy-protected program that does not
require a key disk but requires a special procedure to install
it on a hard disk, set the speed to slow while you are
installing the program. Then set the speed to fast while you
load and run the program.
If this does not work, try installing and loading the program
at slow speed and then change to fast speed to run it. Do
not set the speed to change automatically.
There are three ways to change the processor speed:
0 Run the SETUP program
0 Enter a keyboard command
Q Run the ESPEED program.
If you frequently use programs that require slow or automatic
speed, use SETUP to change the processor speed. See Chapter 2
of the Setup Guide for instructions.
If you use these programs only occasionally, you should use
the keyboard commands or the ESPEED program (described
below) to change the processor speed.

Entering Keyboard Commands
You can change the processor speed by entering one of the
commands shown in the following table.
Speed setting commands
Numeric keypad commands

To enter these commands, hold down the [key and the
[lutl key simultaneously and then press the m or m key.
Use the [+1 or [-I 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 the
same commands for another function, you cannot use it to
change the processor speed. For example, if you are running
a program that uses the [cbt [‘[:I command to move
the cursor, you cannot enter [m [Alt) 17 to change the
processor speed to slow. Another alternative is to use the
ESPEED program, described below.
The speed setting remains in effect until you press the RESET
button or turn off the computer, or until you change it again
using the SETUP program, another keyboard command, or the
ESPEED program.
2-4
Enhancing System Operations
Using the ESPEED Program
ESPEED provides an easy way to change the processor speed if
your application program does not recognize the [ctrll key
commands or if you want to include the program command in
a batch file.
The ESPEED program is provided on the Reference diskette. If
you copied this file onto your hard disk, log onto the drive
where it is stored. If you do not have a hard disk, insert your
Reference diskette in drive A and log onto drive A before you
enter the command to start the program.

the SETUP program; or until you press the RESET button or
turn off the computer.
Entering the ESPEED command in a batch file
You may want to run the ESPEED program by including the
command in a batch file. Let’s say you have a program called
SLOWDOWN which requires a slower processor speed. You
could include the following commands in a batch file to start
the SLOWDOWN program:
ESPEED S
SLOWDOWN
You could name the batch file SLOW.BAT. Whenever you need
to run the SLOWDOWN program, insert the program diskette
in drive A. Then type SLOW and press [Enbr). The computer
changes the speed to slow and starts the SLOWDOWN
program.
See your operating system manuals for instructions on creating
and using batch files.

Enhancing System Operations
Using Your Computer as a Network Server
A network sever is the master computer in a network and
provides storage space for the other computers connected to it.
It can also write files to and read files from the other computers.
Even if no one is typing commands at the network server
keyboard, the server can process commands sent to it from
other computers. If you use your computer as the network
server, you may want to prevent unauthorized users from
entering commands at the keyboard. To provide this security,
you can enable a power-on password in network server mode
using the SETUP program.
If you set a power-on password but do not turn on network
server mode, you enter the password before the computer loads
the operating system or the network software. Once you load it,
anyone can access your system by typing commands on the
keyboard. However, if you set a password and turn on network
server mode, you can load your operating system or network
software before you enter the password. This allows other
computers in the network to access the system, but prevents
unauthorized users from entering commands at your keyboard
and using any network server access privileges.
When you boot the computer in network server mode, you do
not see the password prompt ( _ ), as you would if network
server mode was turned off. The prompt is hidden to prevent
unauthorized users from knowing that a password is required.
You do not have to set a password in network server mode
to use your computer as a network server, but it is helpful.
See “Setting the Power-on Password” in Chapter 2 of the
Setup Guide for instructions on setting the password and
enabling network server mode. Then read the next section to
use your network password.

Note
If your hard disk drive has a partition larger than 32MB and
you are using MS-DOS, you must use the MS-DOS SHARE
command to install file sharing and locking protection in a

instructions.
If you do not install SHARE, the following message flashes
on your screen after you install your network software and
reboot your computer:
WARNING! SHARE should be loaded for large media
Using a Password in Network Server Mode
When you turn on or reset the computer, it loads your
operating system or network software and you see either the
command prompt or the first screen displayed by your
network software.
Follow these steps to enter your password:
1. Turn on or reset your computer. You do not see the password
prompt even though the computer is now waiting for you
to enter the correct password.
2. Type your password and press I. The screen does not
display what you type.
Now you should be able to use your computer. Press a key
such as m to see if the keyboard accepts your command. If

as described in Chapter 1 of this manual.
Using Special VGA Features
Your built-in VGA (video graphics array) display adapter
supports both standard VGA monitors and multifrequency
monitors with analog connectors. The VGA adapter operates in
all standard VGA resolutions without requiring any device
drivers. However, if you are using a monitor that supports
extended VGA features, you may want to use one or more of
the device drivers provided on the Utility diskettes.
If you are using your computer’s VGA feature connector and
Install VGA device drivers if you want to use these features:

Installing and Removing Options
You can enhance the performance of your computer by adding
a variety of options, including the following:
0 Option cards
Cl Memory modules
LJ A math coprocessor.
An option card is a circuit board you install in your computer
to add a particular function. Most option cards contain a
device, such as a modem, or provide an interface, such as a
high-resolution graphics card for a VGA monitor or a network
connector. This chapter describes how to install option cards
and configure your computer for use with them.
Memory module-also called SIMMs (single inline memory
modules)-allow you to increase the amount of memory in
your computer. If you want to install SIMMs, you may prefer to
ask your dealer to do it for you. You can, however, follow the
instructions in this chapter to install them yourself. This
chapter describes the SIMMs you can use in your computer.
Note
It is best not to expand your system’s memory by installing
an optional memory card. Using memory modules is more
efficient since you do not need to use one of your option
slots to add memory. Your computer can also access
memory installed on memory modules faster than memory
installed on a card.
installing and Removing Options
4-1
A math coprocessor speeds up the numeric calculations your
computer performs when using certain application software. If
you purchase a math coprocessor, it is a good idea to ask your
dealer to install it for you, because it can be damaged easily. If
you decide to install it yourself, follow the appropriate steps in
this chapter.
This chapter also explains how to change the jumper settings
inside the computer. You may need to change jumper settings if
you install certain types of options or if you want to change the
way your computer operates.
If you need to replace the battery for your computer’s real-time
clock and CMOS RAM, you can follow the instructions in this
chapter.
To change jumper settings, replace the battery, or install the
options mentioned above, you must remove the computer’s
cover and you may need to remove the subassembly. See
Chapter 3 for instructions. (You do not need to remove the
subassembly to install or remove option cards.)

Replacing the Battery
Your computer comes with a 3.6 volt lithium battery that
provides power for the real-time clock and the CMOS RAM.
The real-time clock keeps track of the time for your computer,
and the CMOS RAM stores the information about your system
configuration that was saved by the SETUP program.
This battery lasts approximately three to five years. If it loses
power, you will see an error message when you turn on or reset
your computer. Contact your dealer to obtain a replacement
battery or to install the new battery for you. If you want to
replace the battery yourself, you can follow the instructions in
this section.
Note
When the battery runs out, your computer loses the
information stored in the CMOS RAM and the time stored in
the real-time clock. After you replace the battery, run the

Setting the Hard Disk Drive Jumpers
You may need to change the hard disk drive jumper settings if
you install or remove a hard disk drive. The jumpers tell the
computer whether you are using one hard disk drive or two.
Note
You do not need to set these jumpers if you are removing
your only hard disk drive.
If you are installing just one hard disk drive, see “Changing the
Jumper Settings,” below, to check the jumpers on your drive.
If you are removing one hard disk drive and leaving another in
your computer, you need to change the jumper settings on the
remaining drive to indicate that it will be the only hard disk
drive installed.
If you install two hard disk drives in your system, you must
change the jumper settings on each drive 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 drive and the slave drive, but the operating
system must be contained on the master drive.
Follow the instructions below to change the jumper settings on

Changing the Jumper Settings
The hard disk drive jumpers are usually located on the drive’s
circuit board, near the large cable connector.
jumpers
The instructions in this section describe setting the jumpers on
the standard Epson 120MB hard disk drive. The jumpers on
your drive may be in a slightly different location, but you set
them the same way. See the documentation that came with
your hard disk drive for the proper settings.
There are three positions for the jumpers on the Epson 120MB
hard disk drive.

To move a jumper from one position to the other, use your
fingers, needle-nose pliers, or tweezers to pull it off its pins and
gently move it to the other position. Be careful not to drop the
jumper or damage the pins as you install it.
If you are going to use only one hard disk drive, make sure the
jumper is set in position DS. Then see “Installing a Hard Disk
in the Vertical Position” on the next page for instructions on
installing your first hard disk drive.
If you’ll be using two hard disk drives, install two jumpers on
the master drive in positions SP and DS. Do not install any
jumpers on the slave drive.
If you are installing both of your hard disk drives at one time, it
is easiest to install the drive in the horizontal drive bay first. See
“Installing or Removing a Drive in the Horizontal Position” on
page 5-19 for instructions.
If one of your hard disk drives is already installed in the
computer, follow the steps under “Removing a Hard Disk
From the Vertical Position” on page 5-17 to remove it. Then set
the jumpers on both drives while they are out of the computer.

Installing or Removing a Drive in the Horizontal
Position
This section describes how to install or remove a drive in a
horizontal drive bay. Although the illustrations show a diskette
drive in the lower bay, you can use these same instructions if
you need to install a different drive in the upper drive bay.
If you have a hard disk drive installed in the vertical mounting
position, remove it before you remove or install a drive in the
horizontal drive bay. See “Removing a Hard Disk From the
Vertical Position” above.
Installing a Drive in the Horizontal Position
Before you perform the following steps, be sure that you have
set the jumpers on any hard disk drive(s) you’ll be using. (If
not, see “Setting the Hard Disk Drive Jumpers” on page 5-4 for
instructions.)
If you are adding a 3lh-inch drive, make sure that 5¼-inch
metal mounting frames are attached to the drive so it fits
properly in the drive bay. Epson 3Winch drives come with
mounting frames already installed. If your drive did not come
with frames installed, follow the instructions in the manual that
came with the drive to attach them.
Follow these steps to install a disk drive:
1. If you are installing a 5¼-inch diskette drive, turn it so that
the diskette release latch is above the diskette slot. If you
are installing a 31R-inch diskette drive, turn it so that the
diskette release button is on the right and the drive light is
on the left.
If you are installing a hard disk drive, turn it so that the side
with the components is facing down.

3. Slide the drive into the lower drive bay, toward the back of
the subassembly. Watch the oval holes on the side of the
drive bay so you can see when the holes on the drive are
positioned in the middle of them.
If you are installing a diskette drive, adjust its position so that
the front of the drive lines up with the drive in the upper
bay. (A hard disk drive fits all the way into the bay.)

If you are installing a diskette drive in the lower drive bay,
you may want to turn the subassembly upside down and
place it on your work surface. Then locate the diskette drive
ribbon cable; one end is connected to the top diskette drive
and the other end is free. Use the connector in the middle of
the cable to connect the second drive.
As shown in the next illustration, there is a large slot in this
connector with a small plastic divider near one end of the
slot.

Performing System Diagnostics
Hard Disk Format
The Hard disk format program performs a low-level format on
your hard disk. If your computer came with a factory-installed
hard disk or if you have installed an optional Epson hard disk,
it has already been formatted for you.
You may need to format the hard disk if you have installed a
new, non-Epson hard disk in your computer that has never
received this type of low-level format and did not come with
its own format utility.
You must still partition and format the hard disk for the
operating system after performing this low-level format. See
your operating system manuals for instructions.
Caution
The hard disk format procedure destroys any data on your
hard disk.
You may want to reformat a hard disk if you have a serious
problem with the drive. However, before formatting a disk
with data on it, try every other recovery procedure described in
your operating system manuals. Then back up all the data on
the disk before you begin.
Note
If you do not enter a bad track list before you format the
disk, the format program analyzes the surface of the hard
disk to determine the bad tracks.
Performing System Diagnostics
B-17
Media Analysis
This test identifies the bad tracks on the hard disk by analyzing
the surface of the disk to find them. The program uses three
different bit patterns; formatting the disk, marking the bad
tracks, and displaying the bad track list.
Caution
The Media analysis test destroys any data on your hard disk.
Performance Test
This test checks the performance of your hard disk by
determining the data transfer rate and track-to-track seek time
based on the transfer size, the seek count, and the amount of
data transferred. The program measures the data transfer rate
in kilobytes per second. It reads 64KB of data 15 times and
counts the number of timer ticks using this formula:
Transfer rate = (64KB x 15 x 18.2) / # timer ticks
The program measures track-to-track seek time in milliseconds
using this formula:
Seek time = (# timer ticks x 1000) / 18.2 x 200
The number of seeks in this example is 200. A higher data
transfer rate and a lower seek time indicate better disk
performance.
Seek Test
This test checks the seek capability of the hard disk on the
specified range of cylinders and heads. The program performs
a series of sequential seeks followed by random seeks and
reports any errors.
B-18
Performing System Diagnostics
Read/Verify Test
This test checks the read and verify capability of the hard disk
on the specified range of cylinders and heads. The program
performs both sequential and random read and verify
operations and reports any errors.
Check Test Cylinder
This test checks the test cylinder, which is the last cylinder on
the hard disk. You should perform this test if you receive a
hard disk error when you boot the system.
Force Bad Tracks
Use this test to mark bad tracks on the hard disk without
formatting it.
Caution
The Force bad tracks test destroys any data on your hard
disk.
Hard Disk Error Messages
The diagnostics program displays two types of error messages
while testing the hard disk: messages the program generates
and those the controller generates.
The following message appears if you try to run the
Performance Test with less than 128KB of available memory:

Error Messages
Your computer’s built-in memory (ROM) contains a series of
diagnostic 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.
The RAM test program displays the total amount of memory
currently installed in your system. If the computer finds an
error, it displays an error message on the screen. Write down
the error message and give it to your dealer when reporting a
problem.
If the error is serious, the computer cancels further checking
and halts system initialization. The error message remains on
the screen and the computer locks up. If this happens, contact
your dealer as soon as possible. Report this information and
both the error message and code number to your dealer.

a diskette, try the following steps:
1. You may have inserted the diskette upsidedown or it may
not be inserted all the way. Remove the diskette from the
drive and reinsert it with the label facing up. If the diskette
drive has a latch, be sure to turn it down to secure the
diskette in the drive. (See Chapter 1 for detailed
instructions on inserting and removing diskettes.)
2. If reinserting the diskette does not solve the problem and
you have access to another diskette drive of the same type,
place the diskette in the other drive and repeat the
operation. If this works, the trouble may be in your diskette
drive. See “Diskette Drive Problems,” below.
3.
C-12
Check to see if you have inserted the right type of diskette.
For example, are you trying to read a 1.44MB diskette in a
720KB diskette drive? See “Types of Diskette Drives” in
Chapter 1 for more information.
Troubleshooting
4.
If your diskette is the right type for your drive, see if it is
write-protected. On a 5¼-inch diskette, there may be a
write-protect tab over the notch on its side or there may be
no notch. On a 3Winch diskette, the write-protect switch
may be set to the write-protect position or there may be no
switch. You cannot alter data on a write-protected diskette.
(Some application programs do not function properly if the
diskette is write-protected. Check the program manual.) See
Chapter 1 for information.
5. Is the diskette formatted? A new diskette must be formatted
before you can store data on it. See your operating system
manuals for instructions on formatting diskettes.
6. You may have entered an incorrect diskette drive type when
you ran the SETUP program Run SETUP again to check the
setting. See Chapter 2 of the Setup Guide for instructions.
7. 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.
Troubleshooting
C-13
8. 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:
0 Part of a file is missing
Cl A file includes parts of other files
Ll An expected output file is missing.
If you are using MS-DOS, use CHKDSK to make the necessary
repairs; see your MS-DOS manuals for instructions.
Diskette Drive Problems
If you see an error message or have difficulty with a diskette
drive, check the following:
1. If you are having problems with a new diskette drive that
your dealer installed for you, consult your dealer about the
problem.
2. If you installed the drive yourself, did you carefully follow
all the instructions in Chapter 5 of this manual? Review
the instructions and check all the cable connections to make
sure you have installed it correctly.
3. Did you run the SETUP program to define the correct
type of diskette drive as part of the computer’s
configuration? Did you set the FDD option in SETUP to
Enabled? (See Chapter 2 of the Setup Guide for
instructions.)
C-14 Troubleshooting
4.
If you are still having trouble with the drive, run the
Floppy disk system diagnostic tests, described in
Appendix B. If the diagnostics program indicates an error,
consult your Epson dealer.
5. If the diskette drive is making loud or unusual noises, contact
your Epson dealer.
Hard Disk Problems
If you are having a problem with a hard disk, it could be the
result of improper installation, incomplete disk preparation, or
corrupted data. The suggestions in this section are divided into
three categories:
0 Installing the drive
Cl Preparing the drive for use
tl Accessing data on the drive.
Consult the section that seems most likely to cover the
problem you are having. For example, if you have been able
to use data on your disk in the past but suddenly cannot, see
“Accessing Data on the Drive.”
Caution
If your disk has data on it, be very careful before you
perform any procedure that may erase data (such as
formatting the disk). Always be sure to back up your data
before reformatting or repartitioning the disk drive. Consult
your dealer if you have any questions.
Troubleshooting
C-15
Installing the Drive
If you are having problems with a newly-installed drive, check
the following:
1. If your dealer installed the drive, consult that person about
the problem.
2. If you installed the hard disk in your computer yourself, did
you carefully follow all the instructions in Chapter 5 of this
manual? Review the instructions and check all the cable
connections to make sure you have installed it correctly.
Also check the jumper settings on your drive to make sure
they are set correctly.
3. If you installed a hard disk drive and connected it to the hard
disk drive connector on the main system board, did you
run SETUP to update the computer’s configuration
information? Check to make sure you chose the correct
drive type, and that the FDD option is set to Enabled. See
Chapter 2 of the Setup Guide for instructions.
4. If you installed a non-Epson hard disk drive, was it
physically formatted by the manufacturer? A blank, new
hard disk must be 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; if not, follow
the instructions in Appendix B under “Hard Disk Format.”
Note that this physical type of format is different from
the software-based type of formatting commands (such
as the MS-DOS SELECT or FORMAT commands). See
“Preparing the Drive,” below, for more information.
C-16 Troubleshooting
5. If you installed a hard disk drive with its controller on an
option card, did you disable the built-in hard disk drive
controller and select the correct drive type through SETUP?
See Chapter 2 of the Setup Guide for instructions.
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 of the
Setup Guide for instructions.)
2.
Partition and format the drive for the operating system you
are using. If you are using MS-DOS, instructions for
performing these procedures and installing the operating
system 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 will not be able to
store data on the disk. For example, if you have partitioned the
drive and formatted 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 when you turn on the computer.
If you are sure the hard disk has been installed properly and
you have 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.
If you cannot identify the problem, consult your dealer.
Troubleshooting
C-17
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. Contact your dealer for
information.
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 “Hard Disk Format” in Appendix B and your
operating system manuals 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 your dealer.
Software Problems
If you are having trouble with an application program, try the
following solutions:
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 have inserted the correct diskette in drive A.
C-18 Troubleshooting
2. Your computer can run at either fast speed (33 MHz)
or slow speed (11 MHz). 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 CPU operating speed if necessary.
See “Changing the Processor Speed” in Chapter 2 for
instructions and for information on accommodating
copy-protected programs.
3. If you have entered an MS-DOS command that you want
to stop, there are special key combinations you can type to
tell MS-DOS to stop what it is doing. These methods may
also work in your application programs:
0 Hold down [ctrll and press [cl
D Hold down [cbll and press m.
4. An application program can occasionally lock the
computer, making it unresponsive to the keyboard. If
your computer does not respond when you type on the
keyboard, you can reset it. Follow the instructions in
Chapter 1.
5. If resetting the computer does not help, turn off your
system, wait five seconds, and then turn it back on. Then
you can restart your application program.
If none of these solutions solve your software problem, contact
the software manufacturer for technical support.
Troubleshooting
C-19
Printer Problems
Below are some general steps to follow if you are having
difficulty with your printer. If the problem persists and you
need more detailed information, check your printer manual.
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 of the Setup Guide for instructions or see your
printer manual.
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 parallel port or more than
one serial port, the computer must know which port is
primary and which is secondary. See Chapter 2 of the
Setup Guide for instructions on how to define the parallel
and serial ports using the 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
Rhts#m . This should print the contents of
@@ and press re,
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 the MS-DOS manuals 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.
C-20 Troubleshooting
6. If you are using an application program that requires a
printer driver, make sure the driver is installed properly.
See your application program manual for instructions. Also
see your printer manual for additional instructions on
using your printer with application programs.
7. Try running the Printer adapter diagnostics test if you have
a parallel printer, or the Communication adapter test if you
have a serial printer. Appendix B describes these tests. If
the test indicates an error, contact your printer dealer.
Option Card Problems
If you install an option card and it is not functioning properly,
check the following:
1. Is the option card installed correctly? The most common
problem with option cards is a loose connection. Make sure
the card is well seated in its slot. Check the installation
procedure described in Chapter 4 and also see the
instructions that come 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
configuration after installing the card? See Chapter 2 of the
Setup Guide.
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 cards connector on the back panel?
Troubleshooting
C-21
6. If you installed a high-resolution graphics adapter card, did
you connect it to the alternate VGA interface with the
feature cable? See Chapter 4.
7.
Did you perform the correct setup procedures for the
software you are using with the option card? If
necessary, see your software manual for instructions.
Mouse Problems
If you have trouble with your mouse, check the following:
1. Make sure that your mouse is securely connected to its
port on the back of the computer. Also, make sure you
have connected it to the correct port. See Chapter 1 of the
Setup Guide for more information.
2. If the mouse is connected properly, make sure that jumper
J2 on your computer’s main system board is set correctly
for your mouse. See Chapter 4 for more information.
3. Did you install the mouse driver correctly? See your software
manual and the documentation that came with your mouse
for instructions.
4. If you’re still having trouble, check the documentation
that came with your mouse for any troubleshooting
information, or contact your dealer.
C-22 Troubleshooting
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 or your dealer may
not have installed the SIMMs correctly. The SIMMs may be
installed in the wrong sockets, they may be the wrong type,
or they may not be inserted all the way into their sockets.
If your dealer installed SIMMs for you, contact your dealer;
do not attempt to correct the problem yourself. If you
installed them, see “Adding Memory Modules” 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 of the Setup Guide for
instructions.
3. If you are still having trouble with your SIMMs, write
down any error messages and contact your dealer.
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 battery’s life is exhausted, you may see one of the
following error messages:
CMOS battery state low
