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 HDSIT.COM
ESPEED.EXE

(Chapter 2 and Appendix B explain how to use these programs.)

HDSIT.VER

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

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.

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:

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

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.

1-10

Diskette types it can read from and write to

Because of these incompatibilities, always indicate the diskette
type and density when you label your diskettes. (Usually this
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.

Using Your Computer

1-11

Caring for Diskettes and Diskette Drives

Follow these basic precautions to protect your diskettes and

avoid losing data:

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.

1-12

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

-notch

l

0

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.

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

If you have a 3½-inch diskette drive, insert the diskette with
the label facing up and the metal shutter leading 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.

1-20

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.

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

@El

to log onto that drive.

2.

Type

HDSIT

and press

[Ent#I

: and press

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
executes the commands in the file just as if you had typed each
command from the keyboard.

[Enbrl,

MS-DOS

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
light on the front panel is on. It is off when the computer is
operating at slow speed.

TURBO

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
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

key

disk-the one

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.

Enhancing System Operations

2-3

Entering Keyboard Commands

You can change the processor speed by entering one of the

commands shown in the following table.

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
the cursor, you cannot enter [m

[cbt [‘[:I

[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

using the SETUP program, another keyboard command, or the
ESPEED program.

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
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.

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

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.

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

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
your hard disk drives.
