FCC COMPLIANCE STATEMENT FOR AMERICAN USERS
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protections against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
l
l
l
l
Reorient or relocate the receiving antenna
Increase the separation between the equipment and the receiver
Connect the equipment to an outlet on a circuit different from that to which
the receiver is connected
Consult the dealer or an experienced radio/TV technician for help.
You may find the following booklet prepared by the Federal Communications
Commission helpful:
“Television Interference Handbook”
This booklet is available from the U.S. Government Printing Office, Washington DC
20402. Stock No. 004-000-00450-7
Note: If the interference stops, it was probably caused by the computer or its peripheral devices. To further isolate the problem:
Disconnect the peripheral devices and their input/output cables one at a time. If the
interference stops, it is caused by either the peripheral device or its I/O cable. These
devices usually require shielded I/O cables. For Epson peripheral devices, you can
obtain the proper shielded cable from your dealer. For non-Epson peripheral devices,
contact the manufacturer or dealer for assistance.
WARNING: This equipment has been certified to comply with the limits for a
Class B computing device, pursuant to Subpart B of Part 15 of FCC Rules. Only
peripherals (computer input/output devices, terminals, printers, etc.) certified to
comply with the Class B limits may be attached to this computer. Operation with
noncertified peripherals is likely to result in interference to radio and TV
reception.
The connection of a nonshielded equipment interface cable to this equipment will
invalidate the FCC Certification of this device and may cause interference levels
that exceed the limits established by the FCC for this equipment.
This digital apparatus does not exceed the Class B limits for radio noise emissions
from digital apparatus as set out in the radio interference regulations of the Canadian
Department of Communications.
Le present appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de Classe B prescrites dans le règlement
sur le brouillage radioélectriques édicté par le Ministère des Communications du
Canada.

Introduction
The Epson ® Equity™ 386/25 is a high-performance personal
computer which offers exceptional speed and expandability.
The computer’s 25 MHz 80386 microprocessor makes all your
programs run extremely fast, even when supporting multitasking
operations.
The Equity 386/25 is available in these configurations:
A single diskette drive system with a 1.2MB (megabyte)
5 ¼-inch diskette drive
A hard disk drive system with one 40MB or 100MB hard
disk and a 1.2MB diskette drive.
You can install an additional diskette drive and hard disk drive,
up to a maximum of four drives total (configurable using five
half-height mass storage slots).
All models of the Equity 386/25 include 2MB of internal
memory, nine standard option slots (six 16-bit and three 8-bit),
serial and parallel interfaces, and an IBM® PS/2™- compatible
mouse port. You can easily upgrade your computer by installing
additional memory and adding optional devices.
Because of its industry-standard architecture, the Equity 386/25
is fully compatible with the current installed base of personal
computer hardware and software. You can install just about any
optional device that is compatible with the IBM Personal
Computer, PC XT,™ or PC AT.™
You can expand the computer’s memory up to 16MB by
adding memory modules to a special card that comes with your
computer. Memory modules are efficient because they eliminate
the need to use one of your option slots to add memory to your
system.
Introduction 1
You may also want to install a math coprocessor in your
computer to speed up mathematical calculations. You can add
an Intel® 80387 or a Weitek® 3167 (25 MHz) math coprocessor;
or you can add both by installing a Weitek dual-processor
adapter. Check with your authorized Epson dealer to see which
options are available.
The Equity 386/25 offers several other features to enhance the
speed and security of your computer:
Memory caching. Portions of your system memory are
copied to a high-speed cache buffer so your computer can
access programs and data very quickly.
Shadow RAM. This feature allows you to copy areas of
ROM (read-only memory) into the computer’s 32-bit RAM
(random access memory) to further accelerate system
performance.
Password protection. This optional feature ensures that no
one may access your computer without entering the correct
password.
Automatic configuration. The Setup program automatically
configures the memory and other items included in your
system, making it easier for you to get started.
Your Equity 386/25 comes with version 4.01 of MS-DOS,® the
operating system by Microsoft.® This version of MS-DOS
includes a Shell program, which lets you run MS-DOS
commands by selecting options from on-screen menus. You’ll
find a set of MS-DOS manuals packed in the box with the
computer.
You probably also purchased other software; you can use
virtually any application program designed for the IBM PC,
PC XT, PC AT, or compatible computers on your
Equity 386/25. You may also use powerful 32-bit software—
such as Microsoft Windows/386—with your computer.
2 Introduction
Additionally, Epson has included two time-saving utilities that
make MS-DOS easier to use: HELP and MENU. The HELP
program lets you display information on the screen about any
MS-DOS command. MENU provides an easy way to run many
useful MS-DOS commands.
MS-DOS is not the only operating system you can use with
your computer. If you have a hard disk you also may want to
use MS® OS/2. Among other capabilities, MS OS/2 provides
multitasking, dual-mode processing, and online help. With
Epson’s version of MS OS/2, you can have both MS-DOS and
MS OS/2 on your Equity 386/25; this way, you can select which
operating system to load each time you turn on the computer.
Ask your Epson dealer for more information.

Besides this manual, you should have the following:
The computer and power cord
The keyboard with attached cable
Two keys for locking the computer
Six MS-DOS 4.01 diskettes: Install, Operating 1,
Operating 2, Operating 3, Shell, and Select
A Reference diskette
Four MS-DOS manuals: an Installation Guide, a Shell
User’s Guide, a Reference Manual, and a Command
Summary.
In addition to these items, you need a compatible monitor and
display adapter card. You may also have a printer or other
peripheral device.
You’ll find a warranty card and a registration card with the
computer. Keep the warranty card for your records. Fill out the
registration card now and mail it to Epson. With your
registration card on file, Epson can send you update
information.

Setting Up Your System
Removing the Diskette Drive Protector Card
There is a protector card in the diskette slot of your 5 ¼-inch
diskette drive. This card is inserted at the factory to protect the
read/write heads in the drive. To remove it, turn the diskette
drive latch up until it is horizontal. This causes the card to pop
out slightly so you can pull it out of the slot, as shown below.
(If you have a second 5 ¼-inch diskette drive, be sure to remove
the card from that drive as well.)
Save the protector card and reinsert it whenever you move the
computer. If you don’t plan to use your computer for a week or
more, reinsert the card to help prevent dust from entering the
drive.
Setting Up Your System

Choosing a Location
Before you set up your computer, it’s important to choose a
comfortable, convenient location where it can run properly.
Select a location that provides the following:
A large, sturdy desk or table that can easily support the
weight of your system, including all its components.
A flat, hard surface. Soft surfaces like beds and carpeted
floors attract static electricity, which can erase data on your
disks and damage the computer’s circuitry. Soft surfaces also
prevent proper ventilation.
Good air circulation. Air must be able to move freely under
the system as well as behind it. Leave several inches of space
around the computer to allow ventilation.
Moderate environmental conditions. Protect your computer
from extremes in temperature, humidity, dust, and smoke.
Avoid direct sunlight or any other source of heat. High
humidity also hinders operation, so select a cool, dry area.
Appropriate power sources. To prevent static charges,
connect all your equipment to three-prong, 120-volt
grounded outlets. You need one outlet for the computer, one
for the monitor, and additional outlets for a printer and any
other peripherals. You can plug one peripheral into the
auxiliary power outlet on the back panel of the computer,
reducing the number of wall outlets you need.
No electromagnetic interference. Locate your system away
from any electrical device, such as a telephone, that
generates an electromagnetic field.

Turning On the Computer
After you set up your system, you’re ready to turn on the power.
But first, read the following safety rules to avoid accidentally
damaging your computer or injuring yourself:
Never turn on the computer with a protector card in the
diskette drive.
Do not dismantle any part of the computer. Only remove
the cover to access optional devices or change jumper or
DIP switch settings. If there is a hardware problem you
cannot solve after reading the troubleshooting information
in Appendix B, contact your Epson dealer.
Always turn off the power, disconnect the computer’s
power cord, and wait five seconds before you remove the
computer’s cover.
Do not unplug cables from the computer when the power
is on.
1-16
Setting Up Your System
Never turn off or reset your computer while a disk drive
light is on. This can destroy data stored on disk or make an
entire disk unusable.
Always wait at least five seconds after you turn off the
power before you turn it on again. Turning the power off
and on rapidly can damage the computer’s circuitry.
Do not leave a beverage on top of or next to your system or
any of its components. Spilled liquid can damage the
circuitry of your components.
Follow these steps to turn on your system:
1.
Make sure the power cord is plugged into the AC power
inlet on the back panel of the computer and into a threeprong, 120-volt, grounded electrical outlet.
2. Turn on the monitor, printer, and any other peripheral
devices connected to the computer. (Always turn on the
monitor and any peripheral devices before you turn on the
computer.)
3. To turn on the power, locate the power switch on the right
side of the computer, near the back. Flip the switch up to
the ON position.
Setting Up Your System
1-17
The power indicator on the front panel lights up. After a few
seconds, the computer starts to perform an internal self test.
This is a series of checks the computer completes each time you
turn it on to make sure everything is working correctly. If
anything is wrong, an error message appears on the screen.
You see a message prompting you to insert a system diskette.
(Do not insert a diskette at this point.)
If you cannot see the screen display clearly, use the controls on
your monitor to adjust the brightness and contrast until
characters on the screen are clear and bright. If the display is
not stable, check your monitor’s horizontal and vertical hold
controls.
After you adjust the monitor’s brightness and contrast, flip the
power switch down to turn off the computer. Then turn off the
monitor and any peripherals.
Now go on to Chapter 2 and follow the instructions there to
run the Setup program. After you run Setup, you need to install
MS-DOS using the instructions in your MS-DOS Installation
Guide.
1-18
Setting Up Your System
Chapter 2
Running the Setup Program
The first time you use your Equity 386/25, you need to run the
Setup program on the Reference diskette to define the
computer’s configuration. This is a simple procedure you must
do at least once. (You may need to do it again later, if you
change the configuration.)
The Setup program automatically configures parts of your
system and lets you set (or change) the following for your
computer:
Extended memory caching
Type of display adapter (video) card installed
Power-on password
Fast boot function
Auto speed function
Shadow RAM function
Real-time clock’s time and date
Hard disk drive configuration
Diskette drive type(s).
The configuration you define with the Setup program is stored
in the computer’s CMOS RAM, which is permanent because it
is backed up by a battery. Whenever you turn on the computer,
it searches the CMOS RAM for the correct installation
information. If the computer discovers a difference between the
information in the CMOS RAM and its actual configuration, it
prompts you to run the Setup program.
Running the Setup Program
2-1
Automatic Configuration
The Equity 386/25 automatically defines your system’s memory
configuration and recognizes a math coprocessor, if you have
installed one. It also detects and configures most of the devices
you may have installed in your system. For this reason, it may
not be necessary for you to change any of the default settings in
the Setup program. However, you should check each of the
options on the Setup menu to verify that the settings are correct
for your system.
You do not need to configure your computer’s memory using the
Setup program. The computer automatically configures the
2MB of memory that comes with your system as 640KB of base
memory and 1024KB of extended memory. If you install even
more memory, Setup configures it as extended memory also.
2-2
Running the Setup Program
Starting the Setup Program
Follow these steps to start the Setup program:
1. Turn off your computer, monitor, and any peripheral
devices, if you have not already done so.
2. Insert the Reference diskette into drive A with the label
facing up and the read/write slot leading into the drive, as
shown below.
Slide the diskette into the drive until it is in all the way.
Then turn the latch down to lock it in a vertical position.
(For more instructions on inserting and removing diskettes,
see Chapter 3.)

Running the Setup Program
2-5
Some errors, such as Time is invalid , do not allow
you to set a default value, so the screen does not display the
Set default value prompt. If you see one of these
errors, press ESC; the screen displays the main Setup menu
so you can enter a new setting.
2.
Be sure Y is highlighted and press Enter. The Setup
program changes the setting that caused the error to a
setting that is more likely to match your system
configuration. The screen displays the main Setup menu:
Exit
Cache

Password
Fast boot
Auto speed
Shadow RAM
Real-time clock
Hard disk drive
Diskette
drive
You should check all the settings in the Setup program to
make sure they are correct for your system. The default
value for the setting that caused the error may not be the
correct one for your particular configuration.
2-6
Running the Setup Program
Moving the Cursor Block
Use and to move the cursor block (the highlighted bar)
through the options on the main Setup menu. After you
highlight the option you want, you can press Enter to select it.
Follow the instructions in the rest of this chapter to use the
Setup program to define your computer’s configuration.
Setting the Extended Memory Caching
Extended memory caching allows your system to work much
faster. When you cache portions of memory, the system copies
information from that memory into a high-speed cache buffer.
Your system can find information more quickly in the cache
buffer than when it looks for it in the system memory. This
greatly improves the speed at which your system performs.
Running the Setup Program
2-7
The Equity 386/25 automatically enables memory caching for
the 640KB of base memory in your system. For the memory
above lMB, the Setup program allows you to turn extended
memory caching on or off. The default setting for extended
memory caching is on for all the extended memory currently
installed in your system. If you have not installed memory above
the 2MB that came with your computer, caching is turned on in
the area from 1MB to 2MB. If you added more memory, Setup
turns on caching from 1MB up to the maximum amount of
memory that you installed.
Most of the time, you should cache all of your extended memory
to maximize the performance of your 32-bit computer.
However, if you install an optional memory card that “shares”
memory with any of the rest of your system memory, you should
turn caching off in the areas of memory which are shared. See
the manual that came with your memory card to see if this is
the case.
To check or change the extended memory cache setting, follow
these steps:
1. At the main Setup menu, highlight Cache . You see the
following submenu and cache table:
2-8
Running the Setup Program
The table indicates the cachable range of extended memory
currently installed in your system. You see ON or OFF in the
first area because your system comes with 2MB of memory and
the extended memory area from 1MB to 2MB is cachable. If you
installed additional memory, you see ON or OFF in all the areas
of memory you have installed. The shaded areas indicate ranges
of memory that are not installed, and are not cachable at this
time.
If your extended memory cache setting is correct, you can skip
the rest of this section.
2.
Press Enter. The cursor block moves to Extended
memory caching and*** SAVE SETTING ***
appears beneath it in the submenu.
3.
Press Enter again. The cursor block moves to the first range
in the cache table. To change the setting for the first
cachable range from ON to OFF or vice versa, press Enter.
4.
If you have not installed memory above 2MB, the rest of
the box is shaded. Press T to move the cursor block to the
submenu.
If you installed memory above 2MB, press to move the
cursor block to the next cachable range. Press Enter to
change the setting from ON to OFF, if necessary.
Then press t to move to the previous cachable range or
to move to the next range. When you are finished, press
to move the cursor block to the submenu.
5. After you set your extended memory cache, highlight
*** SAVE SETTING *** and press Enter to return
to the Setup menu.

Setting the Power-on Password
Setting a power-on password lets you control who can use your
computer. However, you do not need to set a power-on
password to use the Equity 386/25. If you do not want to set a
password, skip this section.
If you set a power-on password, you must enter it at the key
prompt (
) the next time you turn on or reset your
computer. If you cannot enter it correctly, the computer locks
up and does not respond to your keyboard entries. Therefore, if
you set a power-on password, be sure to remember it or write it
down and keep it in a safe place.
If you want to use your computer as a network server, you can
set your password to operate in network server mode after you
enter the password. (See “Using the Equity 386/25 as a Network
Server” in Chapter 3 for more information.)
Follow these steps to set a power-on password and turn on
network server mode (if necessary):
1. At the main Setup menu, highlight Password. This
submenu appears:

The Setup program does not allow you to enter a new
password if one already exists. However, you can easily
change or delete the current password if you know it. See
“Using a Power-on Password” in Chapter 3 for
instructions,
3. Press Enter. You see this prompt:
To enter a password, type any combination of characters
(including letters, numbers, and blank spaces) up to a total
of seven characters. Use the backspace key to delete
mistakes.
Do not use characters requiring the SHIFT key, such as $,
@, or *, in your password. The computer does not recognize
the SHIFT key when you use your password to access the
system.
WARNING
Be sure to remember the password you enter or write it
down and keep it in a safe place. If you cannot remember
the password you enter now, you will not be able to

Setting the Fast Boot Function
The Fast boot function allows you to start up your system faster
by reducing the time it takes the computer to perform its poweron diagnostics. Power-on diagnostics are a series of diagnostics
checks which your computer runs automatically each time you
turn on the power.
2-14
Running the Setup Program
When Fast boot is disabled, the diagnostics program performs
three different tests on your system’s memory and also checks
the internal devices in your computer. When you enable Fast
boot, the program performs abbreviated versions of these tests.
You should enable Fast boot when you are using your computer
in its current configuration. If you install additional memory in
your computer, disable Fast boot before you make the change.
The next time you turn on your computer, it runs complete
power-on diagnostics, allowing you to test your new
configuration thoroughly. Then you can run the Setup program
to enable the Fast boot function again.

Setting the Auto Speed Function
The Equity 386/25 can operate at two speeds: high or low. High
speed is either 25 MHz or 24 MHz (depending on the setting of
an internal jumper). Low speed simulates an 8 MHz operating
speed. You can use the CPU SPEED switch on the computer’s
front panel to select either speed. (See “Selecting the Operating
Speed” in Chapter 3.)
You’ll probably use high speed for almost all your operations.
Some copy-protected application programs, however, require
the computer to run at the low 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 often, you may want to enable the Auto speed
function.
When Auto speed is enabled, the computer automatically
switches to low speed whenever it needs to access a diskette
drive. It runs at high speed for all other operations.
There are different types of copy-protected programs.
Depending on the type you have, you may or may not want to
enable the Auto speed function. Follow these guidelines:
If you are using a copy-protected program that can run only
on a diskette or that requires a key disk, try to start the
program on high speed. If this works, you do not need to
enable the Auto speed function.
If you can’t load the program on high, enable Auto speed.
If you are using a copy-protected program that does not
require a key disk but requires a special procedure to install
the program on a hard disk, set the CPU SPEED switch on
the front panel to LOW while you are installing the program.
Once it is installed, set the switch to HIGH, where you should
be able to leave it while you load and run the program.

instructions in your MS-DOS Installation Guide.
Using the Equity 386/25
3-1
The MS-DOS installation process automatically copies the
MS-DOS files onto your hard disk or generates working copies
of the original MS-DOS diskettes. It is best to make another set
of backup copies of your original MS-DOS diskettes. You may
also want to copy the working diskettes MS-DOS generates if
you do not have a hard disk.
In addition, be sure to make a backup copy of your Reference
diskette; MS-DOS does not create one for you. See “Making
Backup Copies” in this chapter and “Backing Up Data” in
Chapter 4 for instructions on how to copy diskettes.
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. (See “Resetting the Computer” later in this chapter
for instructions on how to reset the computer.) Follow these
steps:
1.
If you do not have a hard disk, insert your Startup diskette
in drive A.
2.

Locking the Computer
The key lock on the front panel of the computer allows you to
lock the cover onto the computer and disable the keyboard and
the RESET button for security. This provides a safeguard
against someone accessing confidential information or altering
your computer’s internal hardware.
For example, you may want to lock the computer while you are
running an application program that features a screen
demonstration that should not be interrupted. When the
computer is locked, it ignores anything typed on the keyboard.
You can lock the computer whether the power is on or off. To
lock it, insert the key with the notch pointing up, as shown in
the following illustration. Then, while pressing the key in
slightly, turn it clockwise to the LOCK position.
To unlock the computer, insert the key with the notch pointing
right and turn the key counterclockwise, to the UNLOCK
position.
Using the Equity 386/25
3-5
You can remove the key in either a locked or unlocked position.
Your Equity 386/25 comes with two keys; store them safely in
different locations in case you misplace one.
Be sure the computer is unlocked before you try to use the
keyboard; otherwise it will not respond to anything you enter.
Selecting the Operating Speed
The Equity 386/25 can operate at two speeds: high and low.
High speed is either 25 MHz or 24 MHz, depending on the
setting of a jumper inside the computer. (See Appendix A for
more information.) Low speed simulates an 8 MHz operating
speed. On high, the computer can access memory faster than on
low.
You will probably use high speed for almost everything you do.
However, certain application programs have specific timing
requirements for diskette access and can run only at the slower
speed. See the manual for your application program to
determine if this is the case.
3-6
Using the Equity 386/25
Use the CPU SPEED switch on the front panel to change the
CPU speed; move it left for low and right for high. When the
computer runs at low speed, the power light is orange; at high
speed, it is green.
Controlling the Volume
Your computer has a speaker which enables it to beep when you
perform certain operations. You can control the speaker’s
loudness with the VOLUME knob on the front panel, shown
below. Turn it to the right to make the sound louder or to the
left to make it quieter.

Stopping a Command or Program
You may sometimes need to stop a command or program while
it is running. Many application programs provide a command
you can use to cancel or even undo an operation. If you have
entered an MS-DOS command that you want to stop, try one of
the following commands:
Hold down the Ctrl key and press C
Hold down the Ctrl key and press Break.
These methods may also work in your application program. If
you cannot stop a particular operation, however, you may need
to reset the computer, as described in the following section.
Caution
It is best not to turn off the computer to stop a program or
command. If you created new data and you have not yet
stored it, the data will be erased if you turn off the computer.
The computer stores your data in its memory until you save
it; but the memory area is erased each time you turn off or
reset the computer.
Resetting the Computer
Occasionally, you may want to clear the computer’s current
settings or its memory without turning it off. This is called
resetting the computer.
If an error occurs and the computer does not respond to your
keyboard entries, you can reset the computer to reload MS-DOS
and try again. However, resetting erases any data in the
computer’s memory that you have not stored; so reset your
computer only if necessary.
3-10
Using the Equity 386/25
WARNING
Do not reset the computer to exit a program unless you have
to. Some application programs classify and store new data
when you exit the program. If you reset the computer without
properly exiting the program, you may lose data.
To reset the computer, MS-DOS must be either on the hard
disk or on a diskette in drive A; so if your computer does not
have a hard disk, insert the Startup diskette in drive A.
There are three ways to reset. Because each is more powerful
than the last, try them in the order listed here:
1.
If you are using MS-DOS, hold down Ctrl and Alt and press
the Del key. The screen goes blank for a moment and then
the computer should reload MS-DOS. If it doesn’t, try the
second method.
2.
Press the RESET button on the front panel. This method
works even when the computer does not respond to your
keyboard entries. If this does not correct the problem, try
the third method.
3. Remove any diskette(s) from the diskette drive(s). Turn off
the computer and wait five seconds. If your computer does
not have a hard disk, insert the Startup diskette in drive A.
Then turn on the computer.

3-11
Using the Equity 386/25 as a Network Server
If you plan to use your Equity 386/25 in a computer network,
you may want to use your computer as the network server. A
network server is the master computer in a network and
provides storage space for the other computers connected to it.
The network server can write files to and read files from the
other computers in the network. The Equity 386/25 is well
equipped to operate as a network server because of its fast
operating speed, storage capacity, and quick access capabilities.
Most networking software assigns certain file access and
programming privileges to the network server that the other
computers in the network do not have. Because of these special
privileges, the Equity 386/25offers an optional network server
mode to provide extra password security when your computer is
operating as a network server. You do not have to set a password
or enable network server mode to use your computer as a
network server, but it prevents unauthorized access to your
computer when it is operating in this special situation.
When you enable network server mode, you can boot the
system and allow the other members of the network to access
the system without knowing the password. Your networking
software determines the access privileges given to the network
members. However, you must enter the password to use the
network server itself (by entering commands on the network
server keyboard).
When you boot the computer from the hard disk in network
server mode, you do not see the key prompt (
) to tell you
when to enter the password (as you would if network server
mode was turned off). The password prompt is hidden to
prevent unauthorized users from accessing the network server
and using its privileged access capabilities. If someone tries to
access the network server, that person cannot tell that a
password is required.
3-12
Using the Equity 386/25
See “Setting the Power-on Password” in Chapter 2 for
instructions on how to set a power-on password and enable
network server mode.
Using a Password in Network Server Mode
After you enable network server mode and boot the system from
the hard disk, you see the following prompt:
C:\>
You do not see the key prompt (
) even though the
computer is waiting for you to enter the correct password.
Follow these steps to enter your password:
1.
Type your password and press Enter. You do not see
anything you type and the prompt does not change.
2. Press Enter again. You see the C : \ > prompt appear again
beneath the first prompt, as shown below.
C:\>
C:\>
Now, you can access the system.
If the C : \ > prompt does not appear, you entered an
incorrect password. Type the correct password and press
Enter twice to access the system.

Changing a Password in Network Server Mode
To change the power-on password when you are using network
server mode, follow these steps:
1.

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 when you want
to. The Equity 386/25 comes with a single diskette drive or one
diskette drive and one hard disk drive. You may install an
additional diskette drive and hard disk drive, up to a maximum
of four drives total (configurable using five half-height mass
storage slots).
This section explains how disks work and tells you how to

How Disks Store Data
The diskette you insert in your computer’s diskette drive is made
of flexible plastic coated with magnetic material. It is enclosed
in a square jacket that is either slightly flexible (5 ¼-inch
diskettes), or hard (3 ½-inch diskettes).
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, there are concentric rings, called tracks
(or cylinders), on which a disk can store data. Double-density
diskettes have either 40 or 80 tracks on each side, and highdensity diskettes have 80 tracks on each side.
Because a hard disk consists of two or more platters stacked on
top of one another, it has four or more sides with many more
tracks per side than a diskette. (The number of tracks depends
on the capacity of the hard disk. You do not need to know how
many sides and tracks your hard disk has.)
3-16
Using the Equity 386/25
A disk is further divided by sectors. To understand what a sector
is, picture the spokes on a bicycle wheel radiating from the
center of the wheel to the tire. The space between one spoke
and the next is like a sector on a diskette; the lines dividing the
sectors cut across the tracks. (See the figure below.) A diskette
can have 8, 9, 15, or 18 sectors per track. The number of sectors
on a hard disk depends on the type of hard disk.
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 area on the disk where the
data is to be written 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 Equity 386/25 comes with one 1.2MB diskette drive. With
this drive, use 5 ¼-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, which is
approximately 500 pages of text. MB stands for megabyte; each
megabyte equals 1,048,576 bytes or 1024KB.
You may also have a second diskette drive, and it may be the
same type or it may be different. The following list describes the
other types of diskette drives you can use in the Equity 386/25
and which diskettes to use with them:
360KB drive-With this drive, use 5 ¼-inch, double-sided,
double-density, 48 TPI (tracks per inch), 360KB diskettes.
(You can also use single-sided, 160KB or 180KB diskettes.)
These diskettes contain 40 tracks per side, 8 or 9 sectors per
track, and hold up to 360KB of information, which is
approximately 150 pages of text. (With 8 sectors per track, a
diskette holds up to 320KB.) KB stands for kilobyte; each
kilobyte equals 1024 bytes. Each byte represents a single
character, such as A, $, or 3.
1.44MB drive-With this drive, use 3 ½-inch, double-sided,
high-density, 135 TPI, 1.44MB diskettes. These diskettes
contain 80 tracks per side, 18 sectors per track, and hold up
to 1.44MB of information, which is approximately 600
pages of text.
720KB drive-With this drive, use 3 ½-inch, double-sided,
double-density, 135 TPI, 720KB diskettes. These diskettes
contain 80 tracks per side, 9 sectors per track, and hold up
to 720KB of information, which is approximately 300 pages
of text.

Drive and diskette incompatibilities
If your computer has more than one type of diskette drive, or if
you use diskettes from other computers with other types of
diskette drives, you need to be aware of certain incompatibilities
between the diskette drives and the diskettes they use.
Because of the size difference, you cannot use 3 ½-inch diskettes
in a 5 ¼-inch drive or vice versa. There are also certain
limitations on using diskettes that are the same size as the drive
but have different capacities. The following tables summarize
the possibilities and limitations.
Using the Equity 386/25
3-19
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 (1.2MB,
360KB, l.44MB, or 720KB), you can copy files from one drive
to another-using the COPY or XCOPY command-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 DISKCOPY command to
copy from one diskette drive to another if the two drives are not
the same type. For more information on the MS-DOS COPY,
XCOPY, and DISKCOPY commands, see Chapter 4.
Caring for Diskettes and Diskette Drives
Follow these basic precautions to protect your diskettes and
avoid losing data:
Do not remove a diskette from the diskette drive 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.
Remove all diskettes before you turn off the computer.
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.
3-20
Using the Equity 386/25
Never wipe, brush, or try to clean diskettes in any way.
Keep diskettes in a moderate environment. They work best
at normal room temperature and in normal humidity. Don’t
leave diskettes sitting in the sun, or in extreme cold or heat.
Keep diskettes away from magnetic fields. (Remember that
diskettes store information magnetically.) There are many
magnetic sources in your home or office, such as electrical
appliances, telephones, and loudspeakers.
Do not place diskettes on top of your monitor or near an
external hard disk drive.
The surface of a 5 ¼-inch diskette is exposed by the read/
write slot. Always hold the diskette by its protective jacket
and never touch the magnetic surface. The oils on your
fingertips can damage it.
If you have a 3 ½-inch diskette drive, do not slide the metal
shutter on the diskette; this exposes its magnetic surface.
Do not place anything on top of your diskettes, and be sure
they do not get bent. A diskette does not rotate properly in
the drive if it has been damaged.
Carefully label your diskettes and be sure to indicate the
diskette type and density. Attach labels firmly but gently,
and only along the top of a diskette (next to the
manufacturer’s label). Do not stick several labels on top of
one another; too many labels can make it difficult to insert
and remove the diskette in the drive.
Using the Equity 386/25
3-21
For a 5 ¼-inch diskette, it is best to write on a label before
you attach it to the diskette. If you need to write on a label
that is already on a 5 ¼-inch diskette, use only a soft-tip
pen-not a ballpoint pen or a pencil.
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.
Inserting and Removing Diskettes
Hold the diskette with the label facing up and the read/write
slot leading into the drive, as shown below.
Slide the diskette into the slot until it is in all the way. 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
diskette drive to access the diskette.
3-22
Using the Equity 386/25
To remove the diskette, turn the latch up until it is horizontal
and the edge of the diskette pops out. Carefully pull out the
diskette, place it in its protective envelope, and store it in a
proper location, such as a diskette container.
If you have a 3 ½-inch diskette drive, insert the diskette with
the label facing up and the metal shutter leading into the drive,
as shown below. Slide the diskette into the drive until it clicks
into place.
To remove the diskette, press the release button. The diskette
pops out of the drive. Pull out the diskette and store it properly.
Using the Equity 386/25
3-23
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 the diskette
or delete any files it contains. If you try to change data stored on
a write-protected diskette, MS-DOS displays an error message.
To write-protect a 5 ¼-inch diskette, cover the small,
rectangular notch (shown below) with an adhesive writeprotect tab. Write-protect tabs usually come with new 5 ¼-inch
diskettes when you buy them.
To remove the write protection, peel off the write-protect tab.
3-24
Using the Equity 386-25
On a 3 ½-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 ½-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.
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 the original MS-DOS and Reference
diskettes that come with the Equity 386/25, and use only the
copies. Store the original diskettes in a safe place away from
your working diskettes.
Copy your data diskettes regularly, whenever you revise them,
to keep them up-to-date, and store them away from your
originals.
Using the Equity 386/25
3-25
To make backup copies of your diskettes, use the DISKCOPY
command, the MS-DOS Shell, or the MENU program. See
Chapter 4, your Shell User’s Guide, or your MS-DOS Reference
Manual for instructions.
It is best to store the programs and data files you use regularly
on the hard disk. Keep backup copies of all your program files
on diskettes, and regularly copy important data files to diskettes
as well. See “Backing up the hard disk” in this chapter for more
information.
Using a Single Diskette Drive
MS-DOS expects the computer to have at least two diskette
drives, and it displays prompts and messages accordingly. If your
system has a single diskette drive, MS-DOS treats your one
drive like two logical drives. This helps you perform operations
that normally require two diskette drives.
Usually, MS-DOS recognizes the first diskette drive (the top
drive on your computer) as drive A and a second diskette drive
as B. If you have only one diskette drive, MS-DOS can treat it
as both A and B.
3-26
Using the Equity 386/25
For example, if you enter a command to copy from A to B,
MS-DOS copies from the first diskette you place in the drive
(A) to the computer’s memory. Then MS-DOS prompts you to
insert another diskette (for drive B) and copies from memory to
the new diskette. When copying is complete, you see a prompt
to insert the original diskette (for drive 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.
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.
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 the
application programs you are using. First 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 you
can remove that diskette and insert the program diskette you
want to use, and load that into memory too. See your
application program manual for detailed instructions.
Using Two Diskette Drives
If you have two diskette drives, you can use the top drive (A)
for loading the operating system and application programs and
the second drive (B) for creating data. If you have a hard disk,
you will probably need the diskette drives just to copy files to
and from the hard disk and to copy diskettes.
Using the Equity 386/25
3-27
Using a Hard Disk Drive
Working with a hard disk is similar to working with a diskette.
However, the hard disk provides several advantages:
A 40MB hard disk can store as much data as approximately
331.2MB diskettes, and a 100MB hard disk can store as
much data as approximately 82 1.2MB diskettes.
Your computer can perform all disk-related operations
faster.
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.
MS-DOS lets you keep related files together in directories and
subdirectories so they are easy to find and use. See Chapter 4 for
instructions on how to use directories.
If your Equity 386/25 has a hard disk drive, follow these
precautions to protect it from damage and to avoid losing data:
Never turn off the computer when the hard disk drive 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.
3-28
Using the Equity 386/25
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 to another part of
the room), you need to prepare the hard disk for moving.
See “Preparing the hard disk for moving,” below, for
instructions.
A hard disk must be partitioned and formatted before you can
use it. Be sure you have performed the procedures in your
MS-DOS Installation Guide to prepare your hard disk for use.
You can enhance the performance of your hard disk by using
the SMARTDRV.SYS device driver and the FASTOPEN
command. See your MS-DOS Reference Manual for
instructions.
Backing up the hard disk
While the hard disk is very reliable, it is essential to back up
your hard disk files to diskettes in case you lose some data
accidentally. Make copies of all your system and application
diskettes before copying the programs to the hard disk. After
you create data files on the hard disk, be sure to copy them to
diskettes whenever you revise them to keep your backup
diskettes up-to-date.
To make copies of your program diskettes before copying them
to the hard disk, use the DISKCOPY command, the MS-DOS
Shell, or the MENU program. To copy your hard disk files onto
diskettes, use the BACKUP, COPY, or XCOPY command; the
MS-DOS Shell; or the MENU program. See Chapter 4, your
Shell User’s Guide, or your MS-DOS Reference Manual for
instructions.
Using the Equity 386/25
3-29
Preparing the hard disk for moving
If you need to move your computer to a new location-whether
it is across the country or just across the room-you should run
the HDSIT program to protect the hard disk during the move.
The HDSIT program moves 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.
Follow these steps to run HDSIT:
1. Exit any program you are using and display the MS-DOS
command prompt on the screen.
2.
Insert the Reference diskette in drive A.
3. Type the following and press Enter:
A:HDSIT
You see a message on the screen that tells 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. You can now turn off
the computer and prepare to move it to the new location.
Turning Off the Computer
Before you turn off your computer, save your data, exit the
program you are using, and remove any diskettes from the
diskette drives. Turn off the computer first, then turn off the
monitor and any peripherals.

Using MS-DOS With Your Equity 386/25
Your Equity 386/25 comes with version 4.01 of MS-DOS. This
operating system manages your computer by organizing the
computer’s memory, controlling the monitor display, receiving
keyboard input, and accessing data.
How much you need to know about MS-DOS depends on how
you will be using your computer. If you plan to use it just to run
application programs, the few MS-DOS commands you’ll need
are introduced in this chapter. If you plan to use advanced
features, refer to your MS-DOS Reference Manual for complete

Starting MS-DOS
Before you can run an MS-DOS application program, MS-DOS
must be loaded in the computer’s memory. If you have a hard
disk and you installed MS-DOS according to the instructions in
your MS-DOS Installation Guide, the computer loads MS-DOS
automatically after you turn on the power (provided no diskette
is in the diskette drive).
If you do not have a hard disk, you need to load MS-DOS when
you turn on the computer. To do this, insert the MS-DOS
Startup diskette in drive A and then turn on the computer.
(The Startup diskette is one of the working diskettes MS-DOS
generates during the installation process. See your MS-DOS
Installation Guide for instructions on how to install the
operating system.)
If you set a power-on password when you ran the Setup
program, the computer displays the key prompt (
) before
loading MS-DOS. At the key prompt, type your power-on
password and press Enter. (See “Using a Power-on Password” in
Chapter 3 for more information.) After you enter your
password, the computer loads MS-DOS.
When MS-DOS is loaded, the screen displays the Shell Start
Programs Menu if you installed the Shell program when you
installed MS-DOS. If you did not install the Shell program, the
screen displays the MS-DOS command prompt, usually C> or
A>. The MS-DOS command prompt identifies the current
drive.
4-2
Using MS-DOS with Your Equity 386/25
Using Drive Designators
MS-DOS uses letters known as drive designators to identify the
disk drives in your computer. If you have one diskette drive, it is
known as drive A. If you have two diskette drives, the top drive
is A and the bottom drive is B.
If you have one hard disk drive, MS-DOS identifies its primary
partition as drive C (even if you have only one diskette drive).
If you have a second hard disk drive, MS-DOS identifies its
primary partition as drive D.
If you created one or more extended partitions on your hard
disk when you installed MS-DOS, the logical drives that make
up the extended partition(s) are identified by drive letters. For
example, if you have one hard disk (one physical drive)
partitioned into three logical drives, the logical drives are C, D,
and E. If you have two hard disk drives partitioned into a total
of five logical drives (three on the first physical drive and two
on the second), the first physical drive is divided into logical
drives C, E, and F, and the second physical drive is divided into
logical drives D and G, as shown here:
drive 1
drive 2
C: (primary)
E:
F:
D: (primary)
G:
Using MS--DOS with Your Equity 386/25
4-3
The Current Drive
At any given time, MS-DOS considers one disk drive to be the
current (or default) drive. The current drive is the drive on
which MS-DOS executes your next command, unless you tell it
to do otherwise. For example, if the current drive is C, and you
enter the DIR (directory) command, MS-DOS lists the files
stored on drive C. If the current drive is A and you type WP and
press Enter, MS-DOS looks on drive A for a file called WP and
executes the instructions in that file. The current drive is the
drive you are logged onto at the time.
The MS-DOS command prompt tells you which drive is the
current drive. The MS-DOS command prompt includes the
current drive’s letter followed by a greater-than symbol.
(Depending on how you installed MS-DOS, it may also include
additional information.) Thus, when you see C> on the screen,
you know the current drive is C. The MS-DOS command
prompt also lets you know that MS-DOS is ready to receive a
command from you.
If you need to access a file or program on another drive, you can
either change the current drive or specify the other drive when
you give the command.
Changing the current drive
To change the current drive, type the letter of the drive you
want to change to, followed by a colon. Then press Enter. For
example, to change the current drive from C to A, type A: at
the C> prompt and press Enter. MS-DOS acknowledges the
change by displaying the command prompt A>. Changing to a
new drive is also known as logging onto that drive.
4-4
Using MS-DOS with Your Equity 386/25
Specifying the drive designator
If you want to access a program or file on another drive without
first changing the current drive, type the drive designator along
with the filename. For example, if you are logged onto drive A
and want to use a file named PROGRAM on drive B, type
B : PROGRAM and press Enter. MS-DOS loads and executes
the file named PROGRAM from drive B but stays logged onto
drive A.
Types of MS-DOS Commands
Each MS-DOS command is either internal or external. Internal
commands are built into MS-DOS; so you can use them any
time after MS-DOS has been loaded into memory. External
commands are separate files which MS-DOS must be able to
find before it can execute the command. If it cannot find the
file, MS-DOS displays an error message.
If you installed MS-DOS according to the instructions in your
MS-DOS Installation Guide, most external commands are
stored in a subdirectory named DOS on the hard disk (unless
you specified a different name when you installed MS-DOS).
The external commands CONFIG.SYS, AUTOEXEC.BAT,
and COMMAND.COM are stored in the root directory. (For
information on directories, see “Using Directories,” later in this
chapter.) MS-DOS automatically finds any external commands
you use in the DOS subdirectory or the root directory because
the installation process has set a path to them. (For information
on setting paths, see “Using Pathnames,” later in this chapter.)
Using MS-DOS with Your Equity 386/25
4-5
If you do not have a hard disk, external commands are stored
on the set of working diskettes generated when you installed
MS-DOS. To use an external MS-DOS command, you must
insert the diskette containing that command into a diskette
drive. To find out which external commands are on which
diskettes, see the list of working diskette contents in your
MS-DOS Installation Guide.
For example, if you want to use the FORMAT command, you
must insert the Startup diskette into a diskette drive. Then you
can either log onto that drive and enter the FORMAT
command or specify the appropriate drive when you enter the
command.
For example, if you have two diskette drives and you want to
format a diskette that is in drive B, you need to insert the
Working 1 diskette into drive A, and log onto drive A. Then
type the following and press Enter:
FORMAT B:
MS-DOS finds the file named FORMAT.COM on the current
drive.
If you are logged onto drive B, you need to type the following
and press Enter:
A:FORMAT B:
This tells MS-DOS to look on drive A for FORMAT.COM
because the current drive is drive B.
4-6
Using MS-DOS with Your Equity 386/25
Entering an MS-DOS Command
To enter an MS-DOS command, you need to type the
command in the correct format. The command format provides
MS-DOS with the information needed to perform a task.
The MS-DOS command format consists of the command name,
parameters, and delimiters. The command name tells MS-DOS
the task you want the computer to perform. Parameters specify
information such as what data you want to process and where to
locate or store a file. Delimiters are characters such as spaces or
commas that separate command names and parameters.
For example, the command to format a diskette in drive A is:
FORMAT is the name of the command that tells MS-DOS to
execute the file FORMAT.COM. The A: is a parameter that
tells MS-DOS what to format-in this case, the diskette in
drive A. The space between FORMAT and A : is the delimiter
that allows MS-DOS to distinguish the command name
(FORMAT) from the parameter (A:).
Some commands also have optional switches you can use. A
switch is a type of parameter that changes the effects of a
command. A forward slash usually precedes a switch. For
example, suppose you want to format a 360KB diskette in a
1.2MB diskette drive. To do this, you add the following switch
to the FORMAT command:
FORMAT A: /4
If you do not add the /4 switch, MS-DOS tries to format the
360KB diskette as a 1.2MB diskette.
Losing MS-DOS with Your Equity 386/25
4-7
See your MS-DOS Reference Manual for more information on
the command format and for command descriptions that
explain which parameters and delimiters are required and which
parameters and switches are optional for each command.
You can enter an MS-DOS command whenever you see the
MS-DOS command prompt. Type the command name and any
parameters and delimiters. You can type command names and
parameters in either uppercase or lowercase letters. Then press
Enter to execute the command.
If you make a mistake when typing a command and you notice
it before you press Enter, you can do either of two things:
Use the backspace key to delete the error
Press ESC and then Enter to cancel the current command
line and move to a new one.
Then reenter the command correctly.
If you press Enter when a command line has an error in it, the
screen displays an error message. Usually, the MS-DOS
command prompt reappears so you can try again. Type the
correct command and press Enter.
Setting the Date and Time
The real-time clock in your Equity 386/25 constantly tracks the
correct time and date-even when the computer is turned off,
To adjust the time for daylight savings time, you can use the
MS-DOS TIME and DATE commands. See your MS-DOS
Reference Manual for instructions. The computer automatically
changes the date for leap years.

Using MS-DOS with Your Equity 386/25
Creating and Managing Files
All your data and programs are stored in files on disk. A data
file contains information, such as words, numbers, or pictures. A
program file contains coded instructions that the computer can
understand and execute.
The kind of file you create depends on the MS-DOS command
or application program you use to create it. In general, a data
file that you create using an application program is stored in a
special format. If you use a different application program to read
that file, you may encounter problems.
When you create a file, you need to give it a name. The name
must be in the format MS-DOS requires.
Naming Files
Each file must have a unique name so that you can retrieve it
when you need to. The name consists of two parts: the filename
and the extension (which is optional).
The filename can be up to eight characters long. Create a
filename that identifies the information the file contains. You
can use any characters or numbers except for blank spaces and
the following symbols:
Using MS--DOS with Your Equity 386/25
4-9
The extension is optional and can be up to three characters
long. You can use the extension to further identify a file or to
describe what type of file it is, such as a text file or program file.
When you use an extension, separate it from the filename with
a period, like this:
DATA.TXT
Do not use uppercase and lowercase letters to distinguish
between files. MS-DOS does not recognize the difference and
displays all filenames in uppercase.
Some application programs automatically add extensions to the
files you create. These programs use the extension to determine
whether a data file is compatible. Avoid using the same
extensions that your application programs use.
MS-DOS reserves certain filenames for its own use. The
reserved filenames are:
AUX
CLOCK$
COMl
COM2
COM3
COM4
CON
LPTl
LPT2
LPT3
LST
NUL
PRN
MS-DOS also reserves certain extensions for program files. The
reserved extensions are .COM, .EXE, and .BAT, and files with
these extensions are also sometimes called executable files. Do
not use these reserved filenames and extensions for your data
files.
The extension .BAT denotes a type of executable file called a
batch file. You can use batch files to automate sequences of
MS-DOS commands. Even if you are not a programmer, you
may want to create some batch files to save time. See “Creating
an AUTOEXEC.BAT File” in this chapter for a description of a
particularly useful kind of batch file, an autoexecute batch file.

Using MS-DOS with Your Equity 386/25
Copying Files
You can use the COPY command to copy individual files or
groups of files. COPY is an internal command; you can use it
any time you see the MS-DOS command prompt.
You can use the COPY command to copy files in several ways:
You can copy individual files from one disk to another
You can copy a group of files using wildcard characters
You can copy one or more files and give them new names
You can combine or merge files into one file.
To use the COPY command, type COPY at the MS-DOS
command prompt, followed by the drive designators and
necessary filenames. Then press Enter to execute the command.
For example, to copy the file named REPORT from the diskette
in drive A to the diskette in drive B (using the same name for
the copy as for the original file), type the following and press
Enter:
COPY A:REPORT B:
You now have two files named REPORT, one on the diskette in
drive A and one on the diskette in drive B.
To copy the file named REPORT from the diskette in drive A
to the diskette in drive B using a new name, FACTS, for the
copy, type the following and press Enter:
COPY A:REPORT B:FACTS
The file REPORT remains unchanged on drive A and a new file
named FACTS now exists on drive B.
Using MS-DOS with Your Equity 386/25
4-11
To copy the file named REPORT to the same drive or directory
and name the copy FACTS, type the following and press Enter:
COPY REPORT FACTS
Now you have two files on the current drive that have the same
contents but different names. In this example, you can omit the
drive designators because the original file and the copy are both
on the current drive.
You can use wildcard characters to copy a group of files. There
are two wildcard characters: * and ?. The asterisk represents
any group of characters and the question mark represents any
single character.
For example, to copy all the files on the diskette in drive A to
the diskette in drive B, type the following and press Enter:
COPY A:*.* B:
To copy all files with names that begin with the letters MEMO
and end with any single character (such as MEMO1), type the
following and press Enter:
COPY A:MEMO? B:
You can also use the COPY command to combine several files
into one file. For example, to create a new file called DATA
that consists of the files REPORT, FACTS, and MEMO, type
the following and press Enter:
COPY REPORT + FACTS + MEMO DATA
Now the file DATA consists of REPORT followed by FACTS
followed by MEMO.
4-12
Using MS-DOS with Your Equity 386/25
To copy REPORT, FACTS, and MEMO from drive A to a file
named DATA on drive B, type the following and press Enter:
COPY A:REPORT + A:FACTS + A:MEMO B:DATA
Remember these rules when using the COPY command:
MS-DOS must be able to find the original file and know
where to store the copy; that is, you may need to specify the
drive (and directory, if necessary) for one or both.
You cannot create a new file with the same name and in the
same directory as an existing file.
If there is a file on the destination diskette or directory that
has the same name as the file you are copying, the copy
automatically replaces the existing file. There is no warning
that the existing file is being replaced; so be careful that you
do not accidentally erase a file you want to keep.
If you are copying to a diskette, the diskette must already be
formatted.
Using MS-DOS with Your Equity 386/25
4-13
Renaming Files
You can use the RENAME command to change the name of
a file or group of files on the same disk and directory. For
example, to rename a file named PROSPECT (in the current
directory) to CLIENT, type the following and press Enter:
RENAME PROSPECT CLIENT
You can shorten the RENAME command to REN. For example,
to change the name of a file from HAMMERS to WRENCHES,
you can type the following and press Enter:
REN HAMMERS WRENCHES
You can use wildcards to rename groups of files. For example, to
change the extensions of all files on drive C with the extension
.NEW from .NEW to .OLD, type the following and press Enter:
REN C:*.NEW *.OLD
To add the extension .OLD to all files that begin with the same
characters, MEMO, but end with one varying character, type
the following and press Enter:
REN MEMO? MEMO?.OLD
This command renames files such as MEMO1 and MEMO2 to
MEMO1 .OLD and MEMO2.OLD.
See your MS-DOS Reference Manual for more information on
the RENAME command.
4-14
Using MS-DOS with Your Equity 386/25
Deleting Files
You can delete files you no longer need with the DEL (delete)
command. For example, to delete REPORT.AUG from drive C,
type the following and press Enter:
DEL
C:REPORT.AUG
To delete the file WRENCHES from drive C, type the
following and press Enter:
DEL
C:WRENCHES
To display a prompt asking you to confirm that you want to
delete the file before MS-DOS deletes it, use the /P switch.
Type the following and press Enter:
DEL C:WRENCHES /P
You see this prompt:
C:\WRENCHES,
Delete
(Y/N)?
Press Y and Enter for yes or N and Enter for no.
You can use wildcards to delete groups of files. For example, to
delete all files on the diskette in drive A (in the current
directory), you could type the following and press Enter:
DEL A:*.*
Because deleting all files is a serious procedure, MS-DOS
prompts you to confirm the command when you use the * . *
wildcard combination with the DEL command. Press Y and
Enter to confirm the command and delete all files on the
diskette in drive A or N and Enter to cancel the command.
You may substitute ERASE for DEL in the examples above.
ERASE is a synonym for DEL.

Printing Text Files
If you have a printer attached to your computer, you can print
text files with the PRINT command. In general, you will
probably use application programs to print files, but if you need
to print a text file from the MS-DOS command prompt, follow
the steps below.
To print a text file named STATS.NBA on drive C:
1. Make sure your printer is on and ready to print.
2.
At the MS-DOS command prompt, type the following and
press Enter:
PRINT
C:STATS.NBA
MS-DOS prompts you for the name of the printing device
connected to your computer. (This is usually the name of
the communications port that the printer cable is
connected to, such as LPTl.)
3. Type the name of the device, such as LPT1, and press
Enter. MS-DOS prints the file on your printer.
See your MS-DOS Reference Manual for more information on
the PRINT command.
Using Dir ectories
You can store many files on a diskette, and a hard disk can
store many more. To help you organize this much information,
MS-DOS lets you subdivide a disk into logical units called
directories. Directories allow you to arrange your disk so that files
of similar type or purpose are kept together.
4-16
Using MS-DOS with Your Equity 386/25
Directories are essential for organizing files on a hard disk, and
you might even want to create directories on a 1.2MB diskette.
However, you may not need to create directories if you use
lower capacity diskettes-especially if the diskette contains only
a few large files.
Whenever you format a disk, MS-DOS automatically creates
one main directory. This directory is called the root directory.
Any directories you later create are logically subordinate to the
root directory; that is, they are subdirectories of the root
directory. Here is an example of a simple directory structure:
Root
WORDPROC
directory
DOS
SPDSHEET
In this example, you keep your word processing programs and
data files in a directory called WORDPROC, your spreadsheet
programs and data files in a directory called SPDSHEET, and
MS-DOS files in a directory called DOS. The few files that
MS-DOS needs to find as soon as you turn on your computer
(such as COMMAND.COM, CONFIG.SYS, and
AUTOEXEC.BAT) remain in the root directory at the top
level of the structure.
As the number of files in your WORDPROC and SPDSHEET
directories grows, you can create additional directories
subordinate to those two-like this:
Using MS-DOS with Your Equity 386/25
4-17
This directory tree lets you separate business word processing
files from personal word processing files, and sales spreadsheets
from spreadsheet files used for financial projections.
Your directory structure may be as simple as this example or
much more complex. Organize your disk(s) to suit your needs.
As your needs change, you can modify the structure by deleting
old directories and creating new ones.
Here are some additional points about directories:
Name subdirectories the same way you name files. The
name can include up to eight characters (letters or
numbers), and you can add an extension of up to three
characters.
The root directory does not have a name. It is identified by
the backslash character: \ .
The total number of files and subdirectories in the root
directory must not exceed 512 on a hard disk or 112 on a
1.2MB diskette.
All directories other than the root directory can have any
number of files and subdirectories.
Like hard disks, diskettes have root directories, and you can
create subdirectories on diskettes the same way as you create
subdirectories on a hard disk.
The following sections describe how to create, use, and delete
directories.
4-18
Using MS-DOS with Your Equity 386/25
The Current Directory
MS-DOS always recognizes one directory as the current (or
default) directory, just as it always recognizes one drive as the
current drive. The current directory is the directory you are
logged onto at the time and the one in which MS-DOS
performs your commands, unless you tell it to do otherwise. If
you installed MS-DOS according to the instructions in your
MS-DOS Installation Guide, the MS-DOS command prompt
displays the current directory.
If you want to run a program or access a data file that is not
stored in the current directory, you can either change
directories (making a different directory the current directory)
or include a pathname in your command.
Changing the Current Directory
To change from one directory to another, use the CHDIR
command, or its shorthand equivalent, CD. For example, to
change to the root directory of the current drive from anywhere
in the directory tree, type the following and press Enter:
CHDIR \
If you are in the WORDPROC directory and you want to
change to PERSONAL, a subdirectory of WORDPROC, type
the following and press Enter:
CD
PERSONAL
To change from PERSONAL back to WORDPROC, you can
use the special symbol . . (two periods). The . . symbol always
designates the parent directory, which is the directory one level
above the current directory. You can type:
CD . .
Using MS-DOS with Your Equity 386/25
4-19
Using Pathnames
You use pathnames with MS-DOS commands to tell MS-DOS
how to find its way to the directory you want to access.
Backslashes separate the directories in a pathname. There are
two types of pathnames: absolute and relative. An absolute
pathname begins with a backslash and tells MS-DOS how to
find its way to the desired directory from the root directory. A
relative pathname does not begin with a backslash and tells
MS-DOS how to find its way to the desired directory from the
current directory.
Here is an example of an absolute pathname:
The pathname above tells MS-DOS to start at the root
directory, go down the directory tree to the WORDPROC
directory, and then continue down the tree to the PERSONAL
directory.
Here is an example of a relative pathname:
SALES
The pathname above tells MS-DOS to find a directory named
SALES that is one level below the current directory. Using the
example above, this pathname is valid only if you are logged
onto the SPDSHEET directory.
Relative pathnames can tell MS-DOS to move upward in the
directory tree as well as downward. The symbol . . (two
periods) in a pathname tells MS-DOS to move upward one
level in the tree. For example, if the current directory is
WORDPROC, the pathname . . \DOS tells MS-DOS to move
up one level from WORDPROC (in the example above, to the
root directory) and then find a subdirectory called DOS.
4-20
Using MS-DOS with Your Equity 386/25
You can use either relative or absolute pathnames at any time,
as long as you give MS-DOS enough information to find the
directory or file at the end of the pathname.
Including Filenames With Pathnames
You can use a pathname when you want to access a file that is
not in the current directory. You specify the name of the file
you want to access at the end of the pathname, like this:
TYPE \WORDPROC\PERSONAL\JEANl204.DOC
This command tells MS-DOS to list on screen (TYPE) the
contents of the text file JEAN1204.DOC which is stored in the
directory \ WORDPROC \ PERSONAL. You separate the name
of a file from the name of a directory with a backslash.
Including Drive Letters With Pathnames and Filenames
To access a file stored on a drive other than the current drive,
you need to include a drive designator (A : , for example) as well
as a filename. If the file you want is not stored in the current
directory of that drive, you also need to include a pathname.
For example, if you are logged onto the root directory of drive C
and you want to delete the file JEAN1204.DOC stored in the
directory \ WORDPROC \ PERSONAL of drive A, type the
following and press Enter:
DEL A:\WORDPROC\PERSONAL\JEANl204.DOC
If you change drives and then try to access a file on the previous
drive, MS-DOS remembers which directory was the current
directory the last time you were logged onto that drive. For
example, suppose that the last time you were logged onto
Using MS-DOS with Your Equity 386/25
4-21
drive C, the root directory was the current directory. Now you
are logged onto drive A and you enter the following command
to delete the file JEAN1204.DOC:
DEL C:JEAN1204.DOC
MS-DOS tries to find the file you want in the root directory of
drive C. Because the file is not there, an error message appears
on the screen. You need to enter the complete pathname in
such a case.
If you do not know which is the current directory on another
drive, it is best to include the full pathname whether or not you
need it. You can never give MS-DOS too much information.
To change to another directory on another drive, include the
drive designator in the command-like this:
CD B:\WORDPROC\PERSONAL
Note
MS-DOS provides several commands that make using
pathnames easy. When you use the following commands, you
don’t have to type a full pathname or enter the drive and
directory every time you want to access certain f&s.
The APPEND command lets you specify a search path
for data files and executable files.
The PATH command lets you specify a search path-for
program files and commands.
The SUBST command lets you substitute a drive letter
for a directory path, which is convenient if you type long
pathnames often.
See your MS-DOS Reference Manual for information on
these helpful commands.
4-22
Using
MS-DOS with Your Equity 386/25
Creating Directories
You use the MKDIR command to create directories. For
example, to create a LEDGER directory under the root directory
of the current drive, type the following and press Enter:
MKDIR \LEDGER
You can abbreviate the name of this command to MD. For
example, to create a SALES directory under the LEDGER
directory, type the following and press Enter:
MD \LEDGER\SALES
If the current directory is the LEDGER directory, you can create
the SALES subdirectory with this command:
MD SALES
Listing the Contents of a Directory
You can use the DIR command to list the contents of a
directory. To list the files in the current directory, type the
following and press Enter:
DIR
MS-DOS lists the names of the files in the current directory on
the current drive, like this:
Volume in drive C is MEMODRIVE
Volume Serial Number is 354C-12E9
Directory of C:\WORDPROC\PERSONAL
11-09-89

A directory listing includes the following information about
each file in the directory:
Name and extension
Size of the file in bytes
Date and time the file was created or last modified
(whichever is later).
The directory listing also shows any subdirectories in the
directory; they are identified by the letters <DIR>. At the top
of the listing, MS-DOS reports any name (volume label) you
have given to the hard disk partition or diskette you are using,
the volume serial number (an identifying code assigned by the
MS-DOS FORMAT command), and the drive and name of
the directory you are viewing. At the bottom of the listing,
MS-DOS indicates the the total number of files (including
subdirectories) in the directory and the number of bytes on the
disk that are still available for use.
If the directory listing is too long to fit on one screen, add the /P
switch to the command, like this:
DIR /P
This switch causes MS-DOS to pause after displaying each
screenful of information. To see the next screenful, press any
key.
You can also use the /W switch to view a long directory listing:
DIR /W
4-24
Using MS-DOS with Your Equity 386/25
This switch displays a wide-format directory listing, like this:
Volume in drive C is MEMODRIVE
Volume Serial Number is 354C-12E9
Directory of C:\WORDPROC\PERSONAL
LETTERS RESUME.713 BOOKRPRT
..
15013560 bytes free
5 File(s)
This type of listing does not show the size of a file or the time
and date it was last modified.
To list the contents of a different drive or directory, include the
appropriate drive designator and/or pathname in the command.
For example, to see what is in the root directory of the diskette
in drive A, type the following and press Enter:
DIR A:\
To display the contents of the WORDPROC \ PERSONAL
directory (on drive C), type the following and press Enter:
DIR
C:\WORDPROC\PERSONAL
Displaying a List of Directories
The TREE command displays a tree diagram of all the
subdirectories of the directory you specify. For example, to see
the names of all the subdirectories of the current directory, type
the following and press Enter:
TREE
Using MS-DOS with Your Equity 386/25
4-25
The screen displays a tree diagram of the subdirectories of the
current directory, for example:
To see a list of all the files in the subdirectories, add the /F
switch, like this:
TREE /F
The screen displays the directory information shown above and
the names of all the files in each subdirectory:
4-26
Using MS-DOS with Your Equity 386/25
To see the list of subdirectories of another directory, include the
pathname:
TREE
C:\ WORDPRO c
Removing Directories
You may sometimes want to remove directories you no longer
need. However, before you can delete a directory, it must be
empty. If it contains any files or subdirectories, MS-DOS
displays an error message and does not delete the directory.
(Use the DEL command to delete the files in a directory or the
COPY command to move them to another directory.)
To delete an empty directory from a disk, use the RMDIR
command, or its shorthand equivalent, RD. For example, to
remove the directory ACCOUNTS, which is a subdirectory in
the LEDGER directory on drive C, type the following and press
Enter:
RD C:\LEDGER\ACCOUNTS
If you are in the LEDGER directory, you can type the following
and press Enter:
RD ACCOUNTS
Formatting Diskettes
Before you can store data on a new diskette, you must format it.
Formatting prepares the diskette so that MS-DOS can write to
it. You need to do this only once, before you use the diskette for
the first time.
Using MS--DOS with Your Equity 386/25
4-27
You can reformat previously used diskettes. This process erases
all data on the diskette, so be sure you do not want to save any
of the data on a used diskette before you format it.
If you plan to use a new diskette to make a backup copy of
another diskette, you do not need to use the FORMAT
command to format it first. The DISKCOPY command
automatically formats a blank diskette if it has never been
formatted. (See “Using the DISKCOPY Command,” later in
this chapter.)
Also see your MS-DOS Reference Manual for information
about the optional switches you can use with the FORMAT
command to format various diskette types in different types of
drives.
Using the FORMAT Command
1.
If you do not have a hard disk, insert your Working 1
diskette into drive A, and log onto drive A.
If you have a hard disk, type C : and press Enter to log onto
drive C.
2. At the MS-DOS prompt, type FORMAT A: and press
Enter. You see this prompt:
Insert new diskette for drive A:
and press ENTER when ready...
4-28
Using MS-DOS with Your Equity 386/25

If necessary, remove the Working 1 diskette from drive A.
Insert the diskette you want to format in drive A and press
Enter to start formatting.
4. When the diskette is formatted, you see this message:

characters,
ENTER
5. At the Volume label prompt, you can enter a name
to describe the information the diskette will contain. The
name (the volume label) will appear whenever you view the
contents of a directory on the diskette using the DIR
command. The volume label can be up to 11 characters
long and can consist of any characters or numbers, except
for blank spaces and the following symbols:
After you name the diskette, press Enter. (If you do not
want to name the diskette, simply press Enter.) Then you
see messages such as the following:
1213952 bytes total disk space
1213952 bytes available on disk
512 bytes in each allocation unit
2371 allocation units available on disk
Volume Serial Number is 3915-16EE
Format another (Y/N)?
6. To format another diskette, press Y and Enter. To return to
the MS-DOS command prompt, press N and Enter.

4-29
Formatting a diskette to 360KB
If you want to format a 360KB diskette in your 1.2MB diskette
drive, you need to use a switch with the FORMAT command.
The /4 switch tells the FORMAT command to format a 360KB
diskette in your 1.2MB diskette drive. Enter the following
command when you follow the instructions in this section to
format a diskette:
FORMAT A: /4
Note
Backing Up Data
It is very important to keep backup diskettes containing copies
of the files you create. You can copy your data (text and
program files) in several ways:
You can use the COPY or XCOPY command to copy
individual files or groups of files.
You can use the DISKCOPY command to make an exact
duplicate of a diskette.
You can use the BACKUP command to back up hard disk
files to diskettes. Because BACKUP can split large files
across two or more diskettes, it makes more efficient use of
diskette space than COPY or XCOPY. It also allows you to
back up files that are larger than the capacity of your
diskettes. To access files created with BACKUP, you use
the RESTORE command.
4-30
Using MS-DOS with Your Equity 386/25
DISKCOPY, BACKUP, and RESTORE are described below.
“Copying Files,” earlier in this chapter, describes the COPY
command. See your MS-DOS Reference Manual for
information on XCOPY.
Note
Using the DISKCOPY Command
The DISKCOPY command lets you make an exact copy of a
diskette. (You cannot use DISKCOPY to copy to or from a
hard disk.) Because this procedure copies the data byte by byte,
the two diskettes must be of the same type. For example, you
cannot use DISKCOPY to copy a 360KB diskette to a 1.2MB
diskette or a 720KB diskette to a 1.44MB diskette. (Use the
COPY command to copy files between different types of
diskettes and to copy files to or from a hard disk.)
If the diskette you are copying to has never been formatted,
DISKCOPY formats it automatically before copying the data.
T he procedure for copying diskettes depends on whether you
have one or two diskette drives. See the following instructions
for your configuration.
Using MS-DOS with Your Equity 386/25
4-31
Using DISKCOPY with one diskette drive
1. Make sure the diskette you want to copy is write-protected.
(See Chapter 3 for instructions.)
2.
If you don’t have a hard disk, insert your Working 1 diskette
into drive A.
3.
If you have a hard disk, type C : and press Enter to log onto
drive C. If you do not have a hard disk, type A: and press
Enter to log onto drive A.
4. At the MS-DOS command prompt, type the following and
press Enter:
DISKCOPY A: A:
MS-DOS displays these messages:
Insert SOURCE diskette in drive A:
Press any key to continue . . .
5.
If necessary, remove the Working 1 diskette from drive A.
Insert the diskette you want to copy from (the source
diskette) into the drive. Then press any key. DISKCOPY
starts to copy the contents of the diskette to the computer’s
memory. When the computer’s memory is full, the screen
displays these messages:
Insert TARGET diskette in drive A:
Press any key to continue . . .
6. Remove the source diskette from drive A and insert the
diskette you want to copy to (the target diskette). Then
press any key. If the target diskette is not formatted,
DISKCOPY formats it before copying data to it.
4-32
Using MS-DOS with Your Equity 386/25
7. After DISKCOPY copies the data from memory to the
target diskette, the screen prompts you to insert the source
diskette again to copy the remaining data to the computer’s
memory (if necessary). Insert the source diskette into
drive A and press any key.
8. After DISKCOPY copies the rest of the source diskette’s
data to the computer’s memory, the screen prompts you to
insert the target diskette again to copy the remaining data
from memory to it. Insert the target diskette and press any
key. When the copy is complete, you see this message:

If you have two diskette drives, follow these steps to copy a
diskette:
1.
Make sure the diskette you want to copy is write-protected.
(See Chapter 3 for instructions.)
2.
If you don’t have a hard disk, insert your Working 1 diskette
into drive A.
3. At the MS-DOS command prompt, type the following and
press Enter:
DISKCOPY A: B:

4.
If necessary, remove the Working 1 diskette from drive A.
Insert the diskette you want to copy from (the source
diskette) into drive A and the diskette you want to copy to
(the target diskette) into drive B. Then press any key to
begin copying. If the target diskette is not formatted,
DISKCOPY formats it before copying data to it.
5. When the copy is complete, you see this message:
Copy
another
diskette
(Y/N)?
Press Y to copy another diskette or N to return to the
MS-DOS command prompt.
Using the BACKUP Command
Use the BACKUP command to back up the data on your hard
disk. It provides a convenient and efficient way to copy the files
on the hard disk to diskettes. BACKUP allows you to do the
following:
Split large files across two or more diskettes
Copy only those files that have been modified since the
most recent backup (with the /M switch)
Copy only those files that have been created (or modified)
after a specified date (with the /D switch)
Copy files in the current directory together with files in all
subdirectories of the current directory (with the /S switch)
Automatically format diskettes before copying files.
Unlike COPY, XCOPY, and DISKCOPY, which make readable
copies of files, BACKUP creates files that you cannot access
directly. To return files copied with the BACKUP command to
the hard disk, you need to use the RESTORE command.
4-34
Using MS-DOS with Your Equity 386/25
Make sure you have enough diskettes to back up the data on
your hard disk drive. For example, it takes about 33 1.2MB
diskettes to copy a 40MB hard disk partition that is completely
full.
See your MS-DOS Reference Manual for complete instructions
on using BACKUP and RESTORE.
The MS-DOS Shell Program
The MS-DOS Shell program allows you to execute many
MS-DOS commands and programs by selecting options from
menus. Using the MS-DOS Shell, you can run commands
without having to remember their exact syntax. MS-DOS Shell
makes it easy for you to manage files and directories. It is
especially useful for managing the data on a hard disk, where
you may have hundreds of files. For example, you can easily
view, create, move, rename, and delete files and directories
using MS-DOS Shell.
See your MS-DOS Installation Guide for instructions on how to
install the Shell program and see your MS-DOS Shell User’s
Guide for information on how to use it.
Using the Epson HELP Program
The Epson HELP program lets you display information on the
screen about MS-DOS commands and programs. You can use
HELP in one of three ways:
At the MS-DOS command prompt, you can type HELP
Enter

If you want information about more than one command you
can type HELP followed by the names of the commands,
each separated by a space.
To use the HELP program, follow these steps:
1.
If you don’t have a hard disk, make sure your Working 3
diskette is in drive A.
2.
If necessary, type A : and press Enter to log onto drive A.
3.
If you want to use the HELP menu, type HELP and press
Enter. Use the cursor keys to highlight the command you
want information about and press Enter.
If you want to bypass the HELP menu and see information
about one command, type HELP followed by the name of
that command. For example, to see help information about
the COPY command, type the following and press Enter:
HELP COPY
If you want to see information about more than one
command, type HELP and the names of the commands you
want information about. Separate each command name
with a space, as in the following example:
HELP DISKCOPY FORMAT COPY
The HELP information for the first command is displayed
first.

press ESC to return to the menu.
If you requested information about more than one MS-DOS
command in the HELP command line, press ESC to see
information about the next command.
6.
Press ESC to exit the HELP program.
Using the Epson MENU Program
The Epson MENU program lets you display a menu of
commonly used MS-DOS commands and select the one you
need. It provides an easier way to run MS-DOS commands
because you can execute commands without having to
remember their exact syntax.
To access MENU, follow these steps:
1.
If you do not have a hard disk, insert your Working 3
diskette into drive A and log onto that drive.
2. At the MS-DOS command prompt, type MENU and press
Enter. You see this main menu:

4-37
3. To select an option, use the arrow keys to highlight the
option you want and press Enter. Most options contain
submenus; keep highlighting your selection and pressing
Enter until you select the desired operation.
MENU works by calling external commands which it looks for
on the current disk or path. If you do not have a hard disk and
the diskette in the current drive does not contain a command
called by MENU-for example, BACKUP.COM—you may see
an error message like this when you select an option:
BACKUP.COM is not on the current disk
or path.
Press
any key
to
continue...
If you see a message similar to this one, insert the diskette that
contains the command you selected into drive A and try again.
(To see which commands are on which MS-DOS diskettes,
refer to the list of your working diskette contents in the
MS-DOS Installation Guide.)

MENU Program Options
Following is a description of each MENU option. Your
MS-DOS Reference Manual provides step-by-step instructions
for using each option.
File Utilities
Lets you back up and restore files, replace
files, compare files, change file attributes,
and copy files and directories. This option
does the work of the MS-DOS commands
BACKUP, RESTORE, REPLACE, FC,
ATTRIB, and XCOPY.
Disk Utilities
Lets you check, copy, compare, and format
diskettes. This option provides an easy-touse alternative to the MS-DOS CHKDSK,
DISKCOPY, DISKCOMP, and FORMAT
commands.
Mode Settings
Lets you change your configuration
settings. Also lets you select alternate code
pages (character sets) and redirect data
from the parallel port to the serial port.
Because you can perform so many tasks
from the Mode Settings submenus, this
option is a simpler alternative to the
MS-DOS MODE command.
Help

Using an AUTOEXEC.BAT File
You may want to run some commands every time you turn on
your computer. To run a command or a series of commands
automatically upon startup, you can type the commands in a
special file called AUTOEXEC.BAT. When you load MS-DOS,
it always looks for this file. If MS-DOS finds an
AUTOEXEC.BAT file in the root directory, it executes the
commands in that file.
Here are some tasks you can perform using an
AUTOEXEC.BAT file:
Modify the PATH command to include the directories
containing other software programs you commonly use.
This reduces the number of times you need to change
directories or specify pathnames.
Add the command to start your most commonly used
application program (such as a word processing or
spreadsheet program) so that it loads automatically when
you turn on or reset the computer.
Change the information the MS-DOS command prompt
includes.
See your MS-DOS Reference Manual for instructions on using
the PATH command, the PROMPT command, and any other
commands you want to include in your AUTOEXEC.BAT file.
Also see the chapter on batch processing commands in your
MS-DOS Reference Manual for detailed information about
AUTOEXEC.BAT files.
4-40
Using MS-DOS with Your Equity 386/25
Creating an AUTOEXEC.BAT File
Here is an example of an AUTOEXEC.BAT file:
PATH C:\;C:\DOS;C:\WP
PROMPT $P$G
The first line tells MS-DOS to look for programs or batch files
in the root directory, the DOS directory, and your word
processing directory. This way you can run programs in those
directories without having to specify pathnames in the
commands. The second line changes the MS-DOS command
prompt so that it displays your current directory.
To create an AUTOEXEC.BAT file, you can use any command
or program that lets you create a text-only file. If you have a
word processing program that can save a file as a text-only file
(sometimes called an ASCII text file), you can use that program
to create your AUTOEXEC.BAT file. Name the file
AUTOEXEC.BAT and store it in the root directory of the hard
disk or diskette from which you load MS-DOS.
Using MS-DOS with Your Equity 386/25
4-41
You can also use the MS-DOS COPY or EDLIN command to
create an AUTOEXEC.BAT file. Follow these steps to create
an AUTOEXEC.BAT file with the COPY command:
1.
If you are creating an AUTOEXEC.BAT file on your hard
disk, log onto the root directory of your hard disk. (Type
CD C : \ and press Enter.)
If you are creating an AUTOEXEC.BAT file on your
Startup diskette, insert the Startup diskette into drive A
and log onto that drive.
2. At the MS-DOS command prompt, type the following and
press Enter:
COPY CON:
d:\AUTOEXEC.BAT
where d is the drive that will contain the
AUTOEXEC.BAT file you are creating. This drive must be
the drive from which your computer loads MS-DOS. For
example, if you load MS-DOS from drive C, type the
following and press Enter:
COPY
CON:
C:\AUTOEXEC.BAT
3. Now enter the commands you want to include in the file.
Type them exactly as you want MS-DOS to execute them,
and in the order you want MS-DOS to perform them. Press
Enter at the end of each line. After you type the last
command, press Enter to move the cursor to the next line.
4.
Press F6 and then Enter. MS-DOS copies everything
you typed to the AUTOEXEC.BAT file. From now on,
MS-DOS runs the commands in the AUTOEXEC.BAT file
every time you turn on or reset the computer.
If you need to change anything in the AUTOEXEC.BAT file
later, you can use the same procedure to modify the commands.
See your MS-DOS Reference Manual for more information.

Using MS-DOS with Your Equity 386/25
Using the Video Shadow RAM Function
The Equity 386/25 has a shadow RAM feature which allows
certain types of ROM (read-only memory) to be copied into
RAM (random access memory) so that your system can access it
faster. You can enable shadow RAM for the ROM BIOS area
using the Setup program. (See Chapter 2 for instructions.)
You can also enable shadow RAM for the video portion of
ROM memory. The video shadow RAM function allows your
computer to update its display faster after you enter a command.
This feature operates with Epson- or Paradise”:compatible VGA
cards and most other EGA and VGA cards.
To enable the video shadow RAM function, you must do the
following:
Copy the file ERAMBIOS.SYS from the Reference diskette
to the root directory of the hard disk or the Startup diskette
from which you load MS-DOS.
Modify the CONFIG.SYS file, which is stored in the root
directory of the hard disk or diskette from which you load
MS-DOS.
If you have a word processing program that can save a file as a
text-only file (also called an ASCII text file), you can use that
program to modify the CONFIG.SYS file. Start your word
processing program, load the CONFIG.SYS file, and then add
the following command line above the DEVICE=ANSI.SYS
command line in the file:
DEVICE=ERAMBIOS.SYS
Then save the file as an ASCII text file.
Using MS-DOS with Your Equity 386/25
4-43
The DEVICE=ERAMBIOS.SYS line must be above the
DEVICE=ANSI.SYS line in your CONFIG.SYS file to enable
the video shadow RAM function. Later, if you add other
command lines to the file, make sure that the
DEVICE=ERAMBIOS.SYS line still remains above the
DEVICE=ANSI.SYS line.
You may put the ERAMBIOS.SYS file in a directory other than
the root directory and then add the appropriate pathname to
the DEVICE= line. (For more information on adding a
pathname, see “Using Pathnames” earlier in this chapter.)
If you do not have a word processing program capable of saving
an ASCII text file, you can modify CONFIG.SYS using the
MS-DOS EDLIN utility. EDLIN is a line editing program used
to edit files that are in ASCII format. Follow the steps below to
use EDLIN to modify the CONFIG.SYS file.
1. At the MS-DOS command prompt, type the following and
press Enter:
EDLIN
CONFIG.SYS
You see this display:
End of input file
*
4-44
Using MS-DOS with Your Equity 386/25
2. To view the contents of the CONFIG.SYS file, type L (the
List command) and press Enter. You see the current
CONFIG.SYS file commands preceded by line numbers,
such as the following:
*L
*
l:*BREAK=ON
2: BUFFERS=20
3: FILES=20
4: LASTDRIVE=E
5: SHELL=C:\DOS\COMMAND.COM/P/E:256
6: DEVICE=C:\DOS\ANSI.SYS
7: INSTALL=C:\DOS\FASTOPEN.EXE
C:=(50,25)
(* is the EDLIN command prompt.)
3. To insert text, specify the line number of the line you want
your new text to appear above. For example, since you want
the DEVICE=ERAMBIOS.SYS line to be above the
DEVICE=ANSI.SYS line, you must specify line 6 followed
by the Insert (I) command. Type the following and press
Enter:
*6I
4. After you press Enter, you see the following prompt
indicating you are in insert mode on line 6:
6:*
Using MS-DOS with Your Equity 386/25

Type DEVICE=ERAMBIOS.SYS and press Enter. Then
you see the prompt for the next line:
7:*
5.
Hold down CTRL and press C to exit insert mode. You see
the * prompt.
6. To make sure your command line is inserted, list the
contents of the CONFIG.SYS file again. At the * prompt,
type L and press Enter. You see the new list of commands:
*L
*
7.
l:*BREAK=ON
2: BUFFERS=20
3: FILES=20
4: LASTDRIVE=E
5: SHELL=C:\DOS\COMMAND.COM/P/E:256
6: DEVICE=ERAMBIOS.SYS
7: DEVICE=C:\DOS\ANSI.SYS
8: INSTALL=C:\DOS\FASTOPEN.EXE C:=(50,25)
Type E and press Enter to exit the EDLIN utility and save
the new version of the CONFIG.SYS file.
The old version of the file is automatically renamed
CONFIG.BAK and saved in the root directory along with
the new CONFIG.SYS file.
8. Reset your computer.
4-46
Using MS-DOS with Your Equity 386/25
If your video card is unable to use the video shadow RAM
function, you see the following messages after resetting your
computer:
WARNING! System must have EPSON VGA
Adapter
ERAMBIOS.SYS Driver NOT installed
These messages indicate that your video card is not compatible
with the video shadow RAM function. Therefore, you should
delete the DEVICE=ERAMBIOS.SYS command line from your
CONFIG.SYS file. See the MS-DOS Reference manual for
instructions on how to use EDLIN to delete the command line
from your CONFIG.SYS file.
If your video card is compatible with the video shadow RAM
function, you should notice that the computer updates your
display faster when it performs MS-DOS operations. However,
most word processing programs slow down the video access; so
you may not notice a difference when using your word
processing program.
Using Memory Beyond 640KB
The Equity 386/25 comes with 2MB of random access memory.
MS-DOS and your application programs that run under
MS-DOS use the first 640KB of memory. You can use the
memory above 1MB as extended or expanded memory.
Expanded memory can be used by certain application programs
(such as Lotus® l-2-3®) that support the Lotus/Intel/Microsoft
Expanded Memory Specification (LIM 4.0 EMS).
Using IMS-DOS with Your Equity 386/25
4-47
To use expanded memory, you must modify the file
disk or diskette from which you load MS-DOS. If you have a
(also called an ASCII text file), you can use that program to
program, load the file CONFIG.SYS, and then add the
DEVICE=EMM386.SYS
You can add one or more of the optional switches explained in
the next section to this command line. Then save the file as an
ASCII text file and reset the computer.
If you do not have a word processing program capable of saving
an ASCII text file, you can modify CONFIG.SYS using the
MS-DOS COPY or EDLIN command. To modify
CONFIG.SYS using the COPY command, follow these steps:
1. Log onto the root directory of the hard disk or diskette from
which you boot MS-DOS.
2. Type COPY CONFIG.SYS + CON: and press Enter.
3. Type DEVICE=EMM386.SYS and press Enter. You can
add one or more of the optional switches explained in the
next section to this command line.
4.
Press F6 and then Enter.
5. Reset the computer.
4-48
Using MS-DOS with Your Equity 386/25
Using EMM386.SYS
EMM386.SYS is an expanded memory manager that lets you
use extended memory to emulate expanded memory so that you
can use application programs that support LIM 4.0 EMS.
The full syntax for the command line that activates
EMM386.SYS is:
DEVICE=[d:][path] EMM386.SYS
[X:mmmm-nnnn] [Mx]
[size]
The items in brackets are optional; you do not type any brackets
when you enter this command. The following paragraphs
describe the items in the command line.
The d:path parameter specifies the pathname. You specify the
pathname if the file EMM386.SYS is not in the root directory
of the hard disk or diskette from which you load MS-DOS. For
example, if EMM386.SYS is in a directory called \DOS on
drive C, include the pathname, like this:
DEVICE=C:\DOS\EMM386.SYS
The size parameter allows you to specify the amount of extended
memory to be used as expanded memory. You specify the
amount of memory in kilobytes. If you do not specify a size, the
default value is 256KB.
Using MS-DOS with Your Equity 386/25
4-49
This example tells the computer to use 1024KB (1MB) of
extended memory as expanded memory:
DEVICE=EMM386.SYS
1024
The X:mmmm-nnnn parameter specifies a range of memory to
exclude from the EMM386.SYS command in hexadecimal
notation. EMM386.SYS does not locate its page frame or other
mappable pages in this memory range.
For example, to specify 1024KB of memory as expanded
memory and ensure that EMM386.SYS does not locate any
pages in the address range C400 to C7FF, include this command
in your CONFIG.SYS file:
DEVICE=EMM386.SYS
1024
X:C400-C7FF
You can include more than one X: parameter in your
DEVICE=EMM386.SYS command to exclude more than one
range of memory.
4-50
Using MS--DOS with Your Equity 386/25
The Mx parameter specifies a particular address for the
EMM386.SYS page frame. You specify the address by
substituting a code for x from this table:
For example, if you want EMM386.SYS to locate its page frame
at the address C800, include this command in your
CONFIG.SYS file:
DEVICE=EMM386.SYS
M2
Do not use the Mx parameter unless you need to force
EMM386.SYS to use a particular address.
For more information on using EMM386.SYS, see your
MS-DOS Reference Manual.

Installing Options
You can enhance the performance of your Equity 386/25 by
adding a variety of options, including the following:
A math coprocessor
Memory modules
Option cards.
A math coprocessor speeds up the numeric calculations your
computer performs when using certain application software.
You can install either an Intel 80387 or a Weitek 3167 math
coprocessor, or you can install both using a Weitek dualprocessor adapter to provide an additional socket. If you want to
install a math coprocessor in your computer, ask your authorized
Epson dealer to do it for you.
Memory modules allow you to increase the amount of memory
in your computer. This chapter briefly describes the types and
amounts of memory modules you can use in the Equity 386/25.
If you want to install memory modules, however, ask your dealer
for help.
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 connector to
which you connect a monitor. This chapter describes how to
install option cards and configure the computer for use with
them.
Installing Options
5-1
Note
It is best not to add memory to the, Equity 386/25 by
installing an optional memory card. Any memory card you
could install is 16-bit and would cause your computer
to work slower. Using memory modules is more efficient
since you do not need to use one of your option slots to add
memory.
Adding Memory Modules
The standard Equity 386/25 system comes with 2MB of memory.
You can add SIMMs (single inline memory modules) to increase
the amount of memory in the computer. With added SIMMs,
the total amount of memory in your computer must be one of
the following: 3MB, 4MB, 6MB, 8MB, 9MB, 10MB, 12MB, or
16MB.
Your dealer installs SIMMs on the SIMM card that comes with
your computer. Each SIMM must have an access speed of 80ns
(nanoseconds) or faster to operate properly. Make sure your
dealer uses the correct type of SIMMs.
There are 16 SIMM sockets on the SIMM card organized in
four banks consisting of four sockets each. Each socket can
contain either one 256KB or one 1MB SIMM. You must,
however, add memory modules according to certain guidelines
to preserve the 32-bit access capability of the Equity 386/25.
Here are the guidelines:
All the SIMMs you install must have the same access speed.
You must fill up any memory bank you use. Since each bank
has four sockets, you must install four SIMMs to fill up the
bank.
You must use only one type of SIMM in a bank. For
example, you cannot install two 256KB SIMMs and two
1MB SIMMs in Bank 0; you must install four 256KB or four
1MB SIMMs.
Each bank has a “partner” bank. Bank 0 and Bank 1 are
partner hanks, as are Bank 2 and Bank 3. If you use two
banks, they must both contain the same type of SIMM. For
example, if Bank 0 contains 256KB SIMMs, then so must
Bank 1 (if you use it). Likewise, if Bank 2 contains 1MB
SIMMs, then Bank 3 must also (if you use it).
The following table shows all possible SIMM configurations for
the Equity 386/25.
Possible SIMM configurations
K = 256KB SlMMs
M = 1MB SlMMs
Installing Options 5-3
Remember, your system already has 2MB of memory (consisting
of eight 256KB SIMMs) installed in hanks 0 and 1; so consider
this when you decide how much memory to add. Do not install
SIMMs in any other type of configuration than one of the types
shown in the table.
Once SIMMs have been installed in your computer, the DIP
switches on the main system hoard need to he set correctly so
that your computer knows it has the additional memory.
Usually, your dealer does this for you, hut you may want to
check the DIP switch settings to make sure they are correct. See
Appendix A for instructions.
After additional memory has been installed in your computer,
you need to run the Setup program on your Reference diskette
to set the computer’s memory configuration, as described in
Chapter 2. Also see “Post-installation Setup,” later in this
chapter.

Installing Option Cards
The Equity 386/25 has nine standard option slots. One of the
slots is occupied by the card that controls the serial/parallel
interfaces and the floppy disk drive (known as the SPF card).
The video card that controls your monitor occupies another
slot. This leaves seven slots in which you can install option
cards. You can buy additional option cards from authorized
Epson dealers as well as other vendors.
This section explains how to:
Remove the computer’s cover

Replace the cover.
While you have the cover off, you may need to change jumper
settings inside the computer if you add or remove option cards
such as these:
Hard disk drive controller card
Mouse controller card
Serial/parallel port controller card.
See Appendix A for more information about changing jumper
settings.
Installing Options 5-5
Removing the Cover
To install an option card, you need to remove the cover from
your computer. Follow these steps:
1. Turn off the computer and then any peripherals (including
the monitor and printer) that are attached to it.
2. Disconnect the computer’s power cable from the electrical
outlet and from the back panel. Then disconnect any
peripheral cables that are connected to the computer.
3.
If the computer is locked, you cannot remove the cover.
Unlock it using the key lock, if necessary. (See Chapter 3
for instructions.)
4. Disconnect the keyboard.

Installing an Option Card
The illustration below shows the nine standard option slots
inside the Equity 386/25. (The SPF card occupies slot
number 7.)
Installing Options 5-9
Slots 7 through 9 are designed for 8-bit option cards, and slots 1
through 6 are designed for 16-bit cards. As you can see below, a
16-bit card has a second connector along the bottom.
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, you must follow
these guidelines when deciding which slot to use:
An S-bit card with an additional tab along the bottom must
go in and 8-bit slot.
It is best to leave the SPF card in slot 7 because of the cable
connecting it to the diskette drive(s).
If you install an additional disk drive that uses a controller
card, place the card as close as possible to the disk drive it is
controlling.
Slot 9 can accommodate an 8-bit card only if the card’s
length does not cause it to interfere with the SIMM card.
Some option cards must be installed in a specific slot.
Consult the instructions that come with the card to see if
this is the case.
Follow these steps to install an option card:
1.
Decide which slot you want to use. Then remove the
retaining screw from the top of the metal option slot cover;
hold on to the screw as you remove it so it doesn’t fall into
the computer. Lift out the slot cover.
Keep the screw to secure the option card to the computer.
Store the slot cover in a safe place in case you remove the
option card later.

2. Unpack the option card and adjust any switches or jumpers
on it if necessary. (Check the option card instructions to see
if this is necessary.) When you handle the card, be careful
not to touch any of the contacts on the circuit board,
especially the gold-edged connector pins. 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.
3. Grip the card firmly by the top corners and position it at the
top of the slot, as shown below. Make sure the connector
pins point down and the component side faces the power
supply inside the computer.
4. Insert the card in the slot, guiding it straight down. Once
the connector pins reach the connector slot, push the card
downward firmly (but carefully) to fully insert it, as shown
in the following illustration. You should feel the card fit
into place.
If the card does not go in smoothly, do not force it-pull it
all the way out and try again, keeping it straight as you
insert it.

Removing an Option Card
If you later need to remove an option card, simply reverse the
steps you followed to install it. Remove the screw securing the
card to the back of the computer and pull the card straight up
and out of the slot. Then carefully wrap the card, preferably
with the original packing materials, and place it inside its box
for safe storage. Cover the end of the empty option slot with the
original metal cover and secure it with the retaining screw.

3. To secure the cover, replace the five screws on the back
panel and the two screws on each side panel.
4. Return the computer to its original position and place the
monitor on top, if that is where you use it. Then reconnect
the computer to the monitor, printer, keyboard, and any
other peripherals you have.
5.
Check to be sure the power switch on the computer is in
the OFF position. Then reconnect the power cable to the
back of the computer and to an electrical outlet.
Post-installation Setup
After you install or remove a math coprocessor or memory
modules, you need to run the Setup program on your Reference
diskette so it can automatically update the computer’s
configuration information. If you install or remove any other
type of option card or device, it is important to run Setup to
check if you need to to change any settings. For example, if you
add a hard disk drive, you need to let the computer know the
type of drive you have installed. See Chapter 2 for instructions.
If you install an optional memory card, use the setup program
that comes with the card to configure the computer for use with
the memory card. See your memory card manual for
instructions.
5-16
Installing Options
Additionally, you may also need to add some commands in your
configuration files. See the MS-DOS Reference Manual and the
manual that comes with the option card for instructions.
You may want to test a newly-installed option. Some options
come with their own diagnostics test programs, and you can test
others with the diagnostics programs on your Reference
diskette. You can use the System diagnostics program on your
Reference diskette to test the following:
System memory
Math
coprocessor
Serial and parallel ports
Disk drives
Monitors and display adapters
Dot-matrix printers.

Appendix A
Changing Jumper and DIP Switch Settings
If you change your computer’s configuration or need to alter the
way your computer operates, you may need to change a jumper
or DIP switch setting inside the computer.
A jumper is a small electrical connector that controls one of the
computer’s functions. The jumpers you may need to change are
on the main system board and the SPF (serial/parallel/floppy) card.
A DIP switch is similar to a light switch; you turn it on or off by
flipping the switch. The ON position is shown next to the DIP
switches, which are located on the main system board.
This appendix describes both types of settings and tells you how
to change them, if necessary. You need to change the jumper
settings inside the computer if you want to make modifications
such as the following:
Change the system operating speed from 25 MHz to
24 MHz or vice versa
Add a serial or parallel port on an option card and want to
make that port the primary port
Add an option card that controls a hard disk drive or a mouse.
You must check or change the DIP switch settings if you make
other modifications, such as these:
Add memory modules
Change the size of your base memory
Change the type of monitor you use.
Check the following sections to see if you need to change any of
the jumper or DIP switch settings inside your computer.
Changing Jumper and DIP Switch Settings
A-1
Changing Jumper Settings
A jumper’s setting is determined by where the jumper is placed.
On the main system board, the jumper can be placed either
between pin 1 and pin 2 (position 1-2) or between pin 2 and
pin 3 (position 2-3), as shown below:
Only pin 1 is labelled on the main system board. Pin 2 is always
the middle pin and pin 3 is on the opposite side from pin 1.
Some jumpers on the main system board are different from the
others. The pin positions for these jumpers are shown below:
On the SPF card, the jumper settings are labelled A and B. The
jumper can be placed either between pin A and the middle pin
(position A) or between pin B and the middle pin (position B).
Otherwise, the jumpers look the same as those on the main
system board.

Changing DIP Switch Settings
If you install SIMMs to add memory to your system, you need to
set DIP switches on the main system board to tell the computer
the amount and configuration of the memory you now have.
There are ten DIP switches on the main system board located
near the SIMM card. Switches 1 through 7 control your system
memory configuration. Switches 1 and 2 set the amount of base
memory and switches 3 through 7 indicate the amount and
configuration of your extended memory.
If your software requires that you have a base memory of 256KB
or 512KB, you need to change the setting of DIP switches 1
and 2. The default settings of these switches select 640KB,
which is the amount of base memory required by the MS-DOS
operating system. The table below shows the settings for each
available amount of base memory.

Changing Jumper and DIP Switch Settings
If you have added extra memory by installing SIMMs in your
computer, you should check to make sure that your dealer set
DIP switches 3 through 7 to the correct settings. Your computer
cannot use the additional memory unless the DIP switches are
set correctly; so be sure to check these switches before you turn
on the computer, and change the settings if they do not match
your new memory configuration. The table below shows the
proper settings for each available configuration.

Troubleshooting
You should not encounter any difficulties as you set up and use
your computer, but if anything out of the ordinary happens,
refer to this appendix. You can correct most problems by
adjusting a cable connection, repeating a software procedure, or
resetting the computer.
Besides trying the suggestions in this chapter, you can run
diagnostics checks on the various components of your computer
system. See Appendix D for instructions.
If the suggestions in this appendix or Appendix D do not solve
the problem, contact your authorized Epson dealer. Your dealer
may be able to solve the problem; if not, he or she can refer
you to an Authorized Epson Customer Care Center for service.
If necessary, call the Epson Customer Information number
(1-800-922-8911) for the location of your nearest Authorized
Epson Customer Care Center.
When you contact your dealer or Customer Care Center, be
ready to provide the serial number of your computer, its
configuration (including the type of disk drives, monitor, and
option cards), and the names and version numbers of any
software you are using.
Error Messages
If the screen displays an error message when you turn on the
computer, see Appendix C, “Power-on Diagnostics.” If the
screen displays an error message while you are running system
diagnostics, described in Appendix D, check the error message
table at the end of that appendix for the cause. Then give this
information to your Epson dealer.
Troubleshooting B-l
The Computer Won’t Start
If your computer does not start when you turn on the power,
check the following:
1.
Is the power light on the computer’s front panel on? If not,
remove any diskettes and turn off the power. Check that
the power cord is securely connected to both the AC inlet
on the back panel and an electrical outlet.
Replace the Startup diskette, if necessary, and turn the
computer on again.
B-2
2.
If the computer’s power light still does not come on, check
the electrical outlet for power. Turn off your computer and
unplug the power cord from the wall outlet. Plug a lamp
into the wall outlet, and turn it on to see if the outlet
supplies power.
3.
If the electrical outlet is working and all the connections
are secure but your computer still won’t start, call your
Epson dealer.
Troubleshooting
4. If the computer starts but is taking a long time to complete
its power-on diagnostics, you may have disabled the Fast
boot function and made an extensive change in your
computer’s configuration. Power-on diagnostics may take up
to five minutes to complete if this is the case. If the
computer does not display the MS-DOS prompt after five
minutes, press the RESET button and try again. If that
doesn’t work, insert the Reference diskette and press the
RESET button. If the computer still does not complete
power-on diagnostics after five minutes, contact your Epson
dealer.
The Computer Locks Up
If your computer locks up and does not respond when you type
on the keyboard, follow these steps:
1. Check the key lock to see if it is locked. If it is, the
computer does not respond to anything you enter on the
keyboard. Turn the key counterclockwise to unlock it. (See
Chapter 3 for more information on the key lock.)
2. Some computer operations take longer than others to
complete. For example, the computer takes longer to sort a
database than to accept a single typed character. If your
computer is still locked after a reasonable length of time,
proceed to the next step.
3. Did you enter the correct password? See “Password
Problems,” below.
Troubleshooting B-3
4.
If you are running an application program, see “Software
Problems,” later in this appendix. This section covers
certain problems caused by application programs.
5.
If you want to stop whatever the computer is doing and
return to the MS-DOS command prompt, hold down the
Ctrl key and press Break. In most cases, this solves the
problem. See Chapter 3 for more information on stopping a
command or program.
6.
If your computer still does not respond, you can reset it with
the RESET button. Follow the instructions in Chapter 3.
7. If resetting the computer does not work, turn off the
computer, wait at least five seconds, and turn it on again.
If you do not have a hard disk drive, insert the Startup
diskette in drive A. The computer should load MS-DOS.
Password Problems
If you set a power-on password using the Setup program, you
must enter this password after you turn on your computer before
you can use the system. When you turn on the computer, the
screen displays a key prompt (
). If you do not enter the
correct password, you see an x on the screen to indicate it is
incorrect. The computer gives you a second and third chance to
enter it correctly.
If after three tries you have not entered the correct password,
the computer locks up and does not respond to your keyboard
entries.
B-4
Troubleshooting
If you have any trouble using your power-on password, try the
following:
1.
If you think you know the correct password, reset the
computer and try again. See Chapter 3 for instructions on
using the password.
2.
If you know the current power-on password but you want to
change or delete it, see Chapter 3 for instructions. (You
cannot delete a power-on password and remain in network
server mode.)
3.
If you do not know the current power-on password and you
do not want to set a new one, see “Removing a Password”
below.
4.
If you do not know the current power-on password and you
want to set a new one, see “Setting a New Password” below.
Removing a Password
If you have forgotten your password and you do not want to set
a new one, there are two ways to remove the current password:
Disable the existing password
Disable the password function.
To do either of these procedures, you must reset a jumper on the
main system board.
Troubleshooting B-5
You should disable the existing password if you want to be able
to set a new password later without having to reset a jumper on
the main system board again. See “Disabling an existing
password” below for instructions.
If you disable the password function, you cannot set a new
password unless you perform the steps to disable the existing
password at that time. If you do not want to use a password
anymore, follow the instructions under “Disabling the password
function” below.
Disabling an existing password
If you do not know your power-on password and do not want to
set a new one, follow these steps to disable the existing
password:
1. Turn off the computer and follow the instructions under
“Changing Jumper Settings” in Appendix A to disable the
password function by setting jumper JP9 to position 2-3.
2.
Insert the Reference diskette into drive A and turn on the
computer. You do not see the key prompt.
3. When the Operation Menu appears, highlight Set up
and press Enter. Then see “Setting the Power-on Password”
in Chapter 2 and follow the instructions as if you are going
to enter a new password. However, when you see the
password prompt, press Enter immediately. This clears out
the existing password.
Make sure you save your password setting and that you
highlight * * EXIT AND SAVE * * when you leave
the Setup program.
4.
B-6
Remove the Reference diskette, turn off the computer, and
follow the instructions under “Changing Jumper Settings”
in Appendix A to enable the password function by setting
jumper JP9 to position 1-2.
Troubleshooting
5.
If you do not have a hard disk, insert the Startup diskette in
drive A. Turn on the computer again. You do not see the
key prompt and the computer loads MS-DOS.
Later, if you want to create a power-on password, run Setup and
enter a password. The jumper is already in the correct position.
Disabling the password function
If you do not want to use a power-on password anymore, you
can disable the password function. However, if you want to use
the password function later, your old password is still stored as
the current password. If you want to be able to easily set a
password later, follow the instructions in “Disabling an Existing
Password” above.
To disable the password function, follow the instructions under
“Changing Jumper Settings” in Appendix A to change the
setting of jumper JP9 on the main system board to position 2-3.
Setting a New Password
If you have forgotten your current power-on password and want
to set a new one, follow these steps:
1. Turn off the computer and follow the instructions under
“Changing Jumper Settings” in Appendix A to disable the
password function by setting jumper JP9 to position 2-3.
2. Insert the Reference diskette into drive A and turn on the
computer. You do not see the key prompt.
3. When the Operation Menu appears, highlight Set up
and press Enter. Then follow the instructions under
“Setting the Power-on Password” in Chapter 2 to enter a
new password. (If you want to enable network server mode,
highlight Network Server Mode and press Enter to
turn on the function.)

5.
Remove the Reference diskette, turn off the computer, and
follow the instructions under “Changing Jumper Settings”
in Appendix A to enable the password function by setting
jumper JP9 to position 1-2.
6.
If you do not have a hard disk, insert the Startup diskette in
drive A. Turn on the computer. You see the key prompt
(
). If you enabled network server mode and did not
insert a diskette, you do not see the key prompt. Enter your
new password to access the system. (See “Using the Poweron Password” in Chapter 3.)
Keyboard Problems
If you are having trouble with the keyboard, check the
following:
1.
B-8
If the screen displays a keyboard error when you turn on or
reset the computer, make sure the keyboard is securely
connected to the computer. See “Connecting the
Keyboard” in Chapter 1 for instructions.
Troubleshooting
2.
If nothing happens when you type on the keyboard, see
“The Computer Locks Up,” earlier in this appendix.
3.
If the cursor keys do not work properly, the Num Lock
function may be on. When Num Lock is on, the numeric/
arrow keys on the numeric keypad work only as numbers.
Check to see if the Num Lock indicator in the upper right
corner of the keyboard is lit; if it is, press the Num Lock key
to turn off the function.
Monitor Problems
For monitor problems, check the following:
1.
If there is no display on the screen, check that the monitor’s
power switch is on and that the power light on the monitor
is lit. If the power light is on but you still do not see
anything on the screen, check the monitor’s brightness and
contrast controls.
2.
If the power switch is on but the power light is not, turn off
the monitor’s power, wait five seconds, and turn the power
back on. Wait a few seconds to see if the screen displays any
text.
3.
If the monitor’s power light still does not come on, check
the electrical outlet for power. Turn off your monitor and
unplug it from the wall outlet. Plug a lamp into the wall
outlet and turn it on to see if the outlet supplies power.
4.
If you still do not see anything on the screen, make sure
your monitor is connected to the computer properly. See
“Connecting a Monitor” in Chapter 1 for more details. Also
check the monitor manual for instructions on how to
connect it to the computer.
Troubleshooting B-9
5.
Make sure your monitor and display adapter card match,
and, if your display adapter card has any switches or
jumpers, be sure they are set properly. See “Connecting a
Monitor” in Chapter 1 and the documentation that came
with your monitor and display adapter card for instructions.
6. If you are running an application program, see if you need
to set up the program for the type of monitor and display
adapter card you have. Also make sure you are using the
appropriate monitor and display adapter card for your
software.
B-10
7.
Be sure you have chosen the correct display adapter card
type in the Setup program. See “Setting the Display
Adapter Card Type” in Chapter 2.
8.
If you are using one or more MDA or CGA video cards, you
may need to change the setting of a DIP switch inside your
computer. The switch tells the computer whether you are
using a color or monochrome monitor. If you are using two
different types of video cards, set the switch to the primary
monitor type. See “Changing DIP Switch Settings” in
Appendix A for instructions.
9.
If you are still having difficulty with your monitor, try
running either the Monochrome Display Adapter and CRT
Check or the Color Graphics Display Adapter and CRT
Check, as described in Appendix D. If the diagnostics
program indicates an error, contact the place where you
bought the monitor.
Troubleshooting
Diskette Problems
If you 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 from the
drive and reinsert it with the label facing up. (See Chapter
3 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 you can successfully repeat the operation in the
new drive, the trouble may be in your diskette drive. See
“Diskette Drive Problems,” below.
3. Check to see if you have inserted the right type of diskette.
The diskette type normally appears on the manufacturer’s
label. Here are the guidelines:
In a drive that has a storage capacity of 1.2MB, such as
drive A, use 5 ¼-inch, double-sided, high-density, 96
TPI diskettes. You can also use 360KB diskettes in this
drive, but if you write to a 360KB diskette in this drive,
you may have trouble using the diskette in a 360KB
drive later.
In a drive that has a storage capacity of 360KB, use
5 ¼-inch, double-sided, double-density, 48 TPI
diskettes. You cannot use 1.2MB diskettes in this drive.
In a drive that has a storage capacity of 1.44MB, use
3 ½-inch, double-sided, high-density, 135 TPI diskettes.
This type of drive can also read and write to 720KB
diskettes.
Troubleshooting
B-11
In a drive that has a storage capacity of 720KB, use
3 ½-inch, double-sided, double-density, 135 TPI
diskettes. You cannot use 1.44MB diskettes in this
drive.
See “Types of Diskette Drives” in Chapter 3 for more
information.
4.
If your diskette is the right type for your drive, check to see
if the diskette is write-protected. On a 5 ¼-inch diskette,
there may be a write-protect tab over the notch on the side
of the diskette or there may be no notch at all. On a 3 ½inch diskette, the write-protect switch may be set to the
write-protect position or there may be no switch. You
cannot store or revise data on a write-protected diskette.
See Chapter 3 for information on write-protecting diskettes.
Some application programs do not function properly if the
diskette is write-protected. Check the program manual.
5. You may have entered an incorrect diskette drive type when
you ran the Setup program. Run the Setup program again to
check the setting. See Chapter 2 for instructions.
6.
If MS-DOS displays errors when you try to access data, your
diskette may be defective. MS-DOS error messages that may
indicate a defective diskette include:
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 diskette drive. On your 5 ¼-inch
diskette drive, make sure the diskette drive latch is closed.
Try the operation again. If the problem persists, try
removing the diskette and reinserting it. This may solve the
problem if the diskette was not seated properly in the drive.
B-12
Troubleshooting
Is the diskette formatted? A new diskette must be formatted
before you can store data on it. See Chapter 4 for
instructions on formatting diskettes.
If the error message still occurs, you probably have a
defective diskette. Use the MS-DOS COPY command to
copy the files from the diskette onto another diskette. (See
“Copying Files” in Chapter 4 for instructions.)
If you are not able to copy all the files from the defective
diskette, copy as many as you can and then use the
MS-DOS program RECOVER. This program recovers all
the data that it can read on the diskette. It is specifically
designed to work on disks that may be defective. See your
MS-DOS Reference Manual for instructions on using
RECOVER.
7.
If you see no error messages but there is something wrong
with the data in a file, MS-DOS 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:
Part of a file is missing
A file includes parts of other files
An expected output file is missing.
To make the necessary repairs, use the MS-DOS program
CHKDSK. See your MS-DOS Reference Manual for
instructions.
Troubleshooting
B-13
Diskette Drive Problems
Follow these steps if you are having difficulty with a diskette
drive:
1.
If the diskette is not turning or the diskette drive is making
loud noises, do not attempt any further examination of it.
Contact your Epson dealer.
2.
If your diskette drive read/write heads are dirty, you may
occasionally see this MS-DOS error message:
Error Reading Drive d: Abort,
Retry, or Fail?
To clean the read/write heads, use a diskette drive head
cleaning kit, available in most computer stores.
3.
If you are still having problems with your diskette drive, try
running the Diskette Drives and Controller Check
described in Appendix D. If the diagnostics program
indicates an error, consult your Epson dealer.
Hard Disk Problems
If you are having problems with the hard disk in your computer,
try the following steps:
1.
B-14
Be sure you have installed MS-DOS on the hard disk
according to the instructions in the MS-DOS Installation
Guide.
Troubleshooting
2.
If you have installed MS-DOS on the hard disk but it does
not load MS-DOS when you turn on the computer, it may
be missing one of the MS-DOS system files. Turn off your
computer and insert your Startup diskette into drive A.
Then turn on your computer again.
Type C : and press Enter to log onto the hard disk. If this
works, the next step is to make sure the file
COMMAND.COM is in the root directory of the hard disk.
Type D I R and press Enter.
If COMMAND.COM is in the root directory, use the
MS-DOS COMPARE command to compare the
COMMAND.COM file on your diskette with the
COMMAND.COM file on the hard disk. (See your
MS-DOS Reference Manual for instructions on using
COMPARE.) If the files do not match, use the COPY
command to replace COMMAND.COM on the hard disk
with the COMMAND.COM file on your diskette. Type the
following and press Enter:
COPY A:COMMAND.COM C:
3.
If the hard disk still does not work, the root directory of
your hard disk may be missing some hidden system files.
(Hidden files are not displayed when you list files using the
DIR command.)
To copy the hidden system files from your Startup diskette
to the root directory of the hard disk, type A : to log onto
drive A. Then type the following and press Enter:
SYS C:
4. If you can load MS-DOS from your Startup diskette but you
cannot access data stored on your hard disk, you may have
accidentally repartitioned or reformatted part or all of the
disk.
Troubleshooting
B-15
Use the Display Partition Information option of the FDISK
program to see if your hard disk has an active (bootable)
DOS partition on it. (See the MS-DOS Reference Manual
for instructions on using FDISK.) If it does not, back up all
your hard disk files and then reinstall MS-DOS on the hard
disk. See your MS-DOS Installation Guide for instructions.
If your hard disk does have an active DOS partition, back
up all your hard disk files and then try reformatting your
hard disk using SELECT. See your MS-DOS Installation
Guide for instructions.
5.
If your hard disk is producing a lot of read/write errors or
you are having other serious problems with it, try running
the Hard Disk Drive and Controller diagnostics check,
described in Appendix D. If the diagnostics program
indicates an error, contact your Epson dealer. Never open
the sealed unit that encloses the hard disk.
6.
If you have been using your hard disk for a long time and
begin to see numerous read/write errors, the magnetic
signals on the disk may be getting weak. If this is the case,
you may need to reformat the hard disk. If you decide to do
this, follow these steps:
Back up all the data on the disk using the BACKUP
command (described in the MS-DOS Reference Manual).
Follow the instructions in Appendix E to perform a lowlevel (physical) format.
Follow the instructions in the MS-DOS Installation
Guide to install MS-DOS on the hard disk.
B-16
Troubleshooting
7.
If you have installed a hard disk drive made by another
company in your computer, you need to install MS-DOS.
See the MS-DOS Installation Guide for instructions. If the
hard disk needs a low-level format, do that before you
install MS-DOS. (See Appendix E for instructions.)
8.
If you have installed a hard disk drive that has its controller
on an option card, you may need to change the position of
jumper JP1 on the main system board. See “Changing
Jumper Settings” in Appendix A. Also, if your computer
came with a hard disk drive that you are no longer using, be
sure the cable leading from that drive to the main system
board and the hard disk drive power cable are disconnected.
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
application program diskette in the top drive (drive A).
2.
Your computer can run at either high speed (25 MHz or
24 MHz) or low speed (simulated 8 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 Chapter 3 for instructions.) Also see the
description of the Auto speed function in Chapter 2 for
information on accommodating copy-protected programs.
Troubleshooting
B-17
3.
If you have tried changing the operating speed using the
CPU SPEED switch or the Auto speed function and your
copy-protected application program still does not work
properly, check the following:
Your application program may be having trouble
operating while the shadow RAM function is enabled.
Run the Setup program on your Reference diskette to
disable shadow RAM. See Chapter 2 for instructions.
Then try running your program again.
If disabling the shadow RAM function does not solve
the problem, your program may be having trouble
because of the maximum operating speed of the
computer.
Your computer is set to run at 25 MHz on high speed.
You can reduce this high-speed setting to 24 MHz by
changing the position of two jumpers inside the
computer. This may enable your copy-protected
program to run correctly for the following reason.
If the computer’s high speed is set at 25 MHz and you
use the Auto speed function or the CPU SPEED switch
to select low speed, the computer runs at a low speed of
8.33 MHz. Some copy-protected programs, however,
require an operating speed of exactly 8 MHz to run
properly. If you reduce the high speed to 24 MHz and
then select the low speed (using Auto speed or the CPU
SPEED switch), the computer runs at exactly 8 MHz.
If you have trouble loading or running a copy-protected
program when the high speed is set at 25 MHz, you may
want to change the setting to 24 MHz. See “Changing
Jumper Settings” in Appendix A for instructions on
changing the positions of jumpers JP3 and JP10 on the
main system board. Then try running the program
again.
B-18
Troubleshooting
4.
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.
To interrupt an MS-DOS command while it is executing,
try one of the following commands:
Hold down the Ctrl key and press C
Hold down the Ctrl key and press Break.
5.
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 3.
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 correctly immediately after
you install it, check that the printer has power and is
properly connected to the computer. See Chapter 1 or your
printer manual for instructions on how to connect your
printer to the computer.
Also make sure your printer has paper in it, since many
printers cannot operate without paper.
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.
Troubleshooting
B-19
3.
If you are using more than one parallel port or more than
one serial port, the jumper settings on the SPF card must be
set properly so MS-DOS knows which port is the primary
port and which is the secondary port. See Appendix A for
instructions on how to change jumper settings inside your
computer.
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 Shift and press PrtSc. 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 command or the MENU program. See your printer
manual and the MS-DOS Reference Manual 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 customization is required.
6. Try running the Parallel Port (Printer Interface) Check if
you have a parallel printer, or the Serial Port (RS-232C)
Check if you have a serial printer. Appendix D describes
these diagnostics checks. If the diagnostics test indicates an
error, contact the place where you bought the printer.
B-20
Troubleshooting
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? Check the installation
procedure described in Chapter 5 and also see the
instructions that come with the option card. The most
common problem with option cards is a loose connection.
Make sure the option card is well-seated in its slot.
2.
Did you set the necessary jumpers on the main system board
and the SPF card? See Appendix A for more information.
3.
Did you set the necessary DIP switches or jumpers on the
option card? See your option card manual for instructions.
4.
Did you run the Setup program to redefine your computer’s
configuration after installing the card? See Chapter 2.
5.
Did you install a hard disk drive that has its controller on
an option card? If so, and if your Equity 386/25 came with a
hard disk drive that you are no longer using, be sure the
cable leading from that drive to the main system board and
the hard disk drive power cable are disconnected.
6.
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 option card connector on the back panel?
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 on running the
software setup procedure.
Troubleshooting
B-21
8. If none of the procedures described above solve the
problem, your option card may be having trouble
functioning at the 25 MHz (high) operating speed. Change
the settings of jumpers JP3 and JPl0 on the main system
board to reduce high speed to 24 MHz. See “Changing
Jumper Settings” in Appendix A for instructions.
B-22
Troubleshooting
Appendix C
Power-on Diagnostics
Your computer’s built-in memory (ROM) contains a series of
diagnostics programs, which your computer runs automatically
every time you turn on the power. These programs check
internal devices such as ROM, RAM, the timer, the keyboard
controller, and the hard disk drive. If the computer finds an
error, it displays a specific error number and error message on
the screen.
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 both the error message
and code number.
If the error is not serious, the computer waits for you to resume
further checking. You see this prompt:
(Resume = "Fl" key)
Write down the error message and code number, and then press
F1 to continue. Report the error message and code number to
your dealer when requesting repairs.
The following table lists all the error codes and messages which
may appear during power-on diagnostics checks.

settings are incorrect, run the Setup program (described in
Chapter 2) to automatically set the correct amount of memory
in CMOS RAM. If you installed an optional memory card, you
may need to adjust some DIP switch settings on the card.
For this check, the program writes specific data into memory
and then reads it back in blocks of 64KB. It also makes a parity
check on each block and tests the memory cache. A memory
count is displayed after each block is tested without error. After
the program checks the last block, you see a message such as the
following:
001664 KB OK
You see the power light change from green to red and back

you can use either a 1.2MB diskette or a 360KB diskette; but it
is better to use the higher capacity diskette. In a 360KB drive,
you can use only a 360KB diskette.
To test a 1.44MB drive, you can use a 1.44MB or a 720KB
diskette. However, to test the full capacity of the drive, use only
a 1.44MB diskette. In a 720KB drive, you can use only a 720KB
diskette.

Performing System Diagnostics
You can select the individual tests from the following menu.
Before it performs any checks, the program determines the
number of diskette drives installed in your computer. If you
have more than one drive, you see this prompt each time you
select a test:
Enter drive number ? (l/2)
Select 1 (for drive A) or 2 (for drive B). If any errors occur,
record the error code and message and contact your dealer.
Always have the diskette drive serviced by your dealer or service
center.
When you finish testing the device and return to the menu,
select 0 to exit.
Sequential Seek Check
This test checks the ability of the read/write heads to locate any
part of the diskette. This action by a read/write head is called a
seek. During this test, each head seeks sequentially from the
innermost track to the outermost track. The innermost track is
track 79 for 1.2MB, l.44MB, and 720KB diskettes and track 39
for 360KB diskettes.
Performing System Diagnostics
D-25
Select option 1 from the menu to start this test. The program
displays the number of each track it finds. For example, with a
1.2MB diskette, the first message you see is:
Current track is 79
The track number counts down from 79 to 0 (39 to 0 for a
360KB diskette). The seek is performed by each head, so you see
the count twice. If no errors occur, the menu is displayed.
Random Seek Check
This test is identical to the sequential seek check, except that
the seek operation is performed on each track in random order
instead of sequential order. Select option 2 from the menu to
start this test.
Write, Read Check
This test checks the ability of the selected disk drive to read and
write data on a diskette. The test writes to and reads from each
track on the diskette, starting at the center.
Select option 3 from the menu to start this test.
D-26
Performing System Diagnostics
If you have only one diskette drive, you see a prompt to remove
the the Reference diskette and insert a blank diskette before
running the test. You see these messages:
If using drive 1, remove your Reference Disk.
Insert a formatted blank disk in the drive
before starting the check.
Any data present may be erased.
Start the check ? (Y/N)
Make sure the blank diskette you prepared is in drive A (1),
then select Y. The program displays the current track number as
each cylinder is tested. For example, with a 1.2MB diskette, the
first message you see is:
Current track is 79
After the test is over, be sure to replace the Reference diskette
in drive A before you select another device from the Device List
or exit System diagnostics.
Disk Change Check
This option tests the ability of a diskette drive to detect
whether a diskette has been inserted or removed. Disk changes
cannot be detected by a 360KB diskette drive.
Select option 4 from the menu to start this test. The program
checks the selected drive type; if it is a 360KB drive, you see
these messages:

Parallel Port (Printer Interface) Check
Use this option to test the operation of the primary parallel
printer port. To perform the test, you must insert a special loopback connector into the parallel port so that the computer can
check individual pins of the port. Contact your dealer if you
need a loop-back connector. Note that a different connector is
required to test the serial port.
When you select option 9 from the Device List, you see these
prompts:
Attach loop-back connector to parallel
port before starting the check.
Start the check ? (Y/N)
Insert the loop-back connector. Then select Y to start the
check. The computer checks the port by writing and reading
data and control information, and reports errors for any pins
that are faulty. Note that if you connect a printer cable instead
of a loop-back connector, you will get errors.
Alternate Parallel Port Check
Use this option to test the operation of an additional parallel
port. To perform the test, you must insert the special loop-back
connector into the alternate parallel port so that the computer
can check individual pins of the port.
This test is similar to the Parallel Port Check. For more details,
see the description of the Parallel Port (Printer Interface)
Check.

D-29
Parallel Port (on Video Adapter) Check
Use this option to test the operation of an additional parallel
port on a video adapter. To perform the test, you must insert the
special loop-back connector into the parallel port on the video
adapter so that the computer can check individual pins of the
port.
This test is similar to the Parallel Port Check. For more details,
see the description of the Parallel Port (Printer Interface)
Check.
Serial Port (RS-232C Port) Check
Use this option to test the functions of the primary serial
communications (RS-232C) port. To perform the test, you must
insert a special loop-back connector into the RS-232C port so
that the computer can check individual pins of the port.
Contact your dealer if you need a loop-back connector. Note
that a different connector is required to test the parallel port.
When you select option 11 from the Device List, you see these
prompts:
Attach loop-back connector to serial
port before starting the check.
Start the check ? (Y/N)
Insert the loop-back connector. Then select Y to start the
check.
D-30
Performing System Diagnostics
First, the program checks the serial port control lines to see that
they are able to change from high to low and vice versa. No
messages are displayed during this part of the test unless an error
occurs.
The second test is an echo back check during which the port
sends data to itself in a fixed data format, at all the possible
baud rates. When this test begins, you see these messages:
RS232C echo back check - at various baud rates
Current baud rate is 75
Current test data is 00
Each baud rate is tested in turn, and the display informs you of
the progress of the test. If the port does not become ready
correctly, a timeout error occurs. If any data received does not
match the data sent, a verify error occurs, and the computer
reports the transmitted and received data at the time of the
error.
The final test is an echo back check during which the port
sends data to itself at 9600 baud, using various data formats. At
the start of the test, you see these messages:
RS232C echo back check-with various data formats
Current data format: 5 data bits, 1 stop bit,
parity - NONE
Current test data is 00
Once again, if any data received does not match the data sent, a
verify error occurs, and the computer reports the transmitted
and received data at the time of the error.

D-31
Alternate Serial Port Check
Use this option to test the functions of an additional serial
communications (RS-232C) port. To perform the test you must
insert a special loop-back connector into the alternate serial
port so that the computer can check individual pins of the port.
This test is identical to the check for the primary serial port. For
more details, see the description of the Serial Port (RS-232C
Port) Check.
Dot-matrix Printer Check
Use this option to check the following:
The operation of your printer in IBM-compatibility mode
The compatibility of your printer with the extended
character set your computer uses
The ability of your printer to produce bit-image graphics
and print images of the graphics screen.
When you select option 14 from the Device List, you see this
prompt:
Is dot-matrix printer on-line ? (Y/N)
Check that your printer is connected to the computer and that
it is turned on, loaded with paper, and online. Select Y to
continue, or N to return to the menu.
D-32
Performing System Diagnostics
When you continue the test, the program checks that the
printer is responding correctly. This test detects whether the
printer is offline or whether an interface error exists. If no errors
occur, the computer sends a repeating sequence of ASCII
characters and bit-image data to the printer until you press any
key. The pattern looks like this:
The text data includes all the characters commonly used by
programs that require foreign languages or graphic characters.
If your printer prints different characters than you see in the
illustration, you may need to be careful with certain software.
The bit-image data is sent to the printer using a command
(ESC K) compatible with Epson and IBM printers.

Performing System Diagnostics
Select option 1 from the menu to start this test. The program
displays the number of each cylinder it finds. For example, with
a hard disk, the first message you see is:
Current cylinder is nnn
where nnn is the largest cylinder number used on the drive. The
cylinder number counts down to 0. The seek is performed by the
read/write heads simultaneously, so you see the cylinder
numbers only once. If no errors occur, the menu reappears.
Write, Read Check
This check tests the ability of the hard disk drive to read and
write data. The test writes to and reads from each sector of the
innermost cylinder of the disk, using each head.

Appendix E
Physically Formatting a Hard Disk
This appendix describes how to physically format a hard disk.
Sometimes called a low-level format, this procedure should not
be confused with the logical format performed by the MS-DOS
FORMAT command. The physical formatting of a hard disk is a
separate step that is usually done at the factory by the disk
manufacturer.
If your Equity 386/25 came with a hard disk, that disk has
already been physically formatted. You need only follow the
instructions in the MS-DOS Installation Guide to prepare your
hard disk for use.
If you have installed a hard disk that came with its own format
utility, use that program to physically format the disk.
You may need to use the procedure in this chapter to physically
format a hard disk if either of the following is true:
Your hard disk is producing numerous read/write errors or
you are having other serious problems with the disk.
Sometimes, after a hard disk has been used for a long time,
the disk’s data becomes fragmented, causing the disk to
frequently produce errors. You may need to reformat the
disk in this case.
You have installed a hard disk in your computer that has
never received the low-level format and did not come with
its own format utility.
Physically Formatting a Hard Disk
E-1
In addition to destroying all the data on the hard disk,
formatting removes any partitions defined on the disk by
SELECT or FDISK and the logical formatting performed by
SELECT or FORMAT. After you physically format a new or
used hard disk (using option 1 or 2 of the Hard Disk Format
Menu), you need to install MS-DOS. Follow the instructions in
your MS-DOS Installation Guide. The installation process
automatically partitions and formats the hard disk to prepare it
for use.
Choosing the Type of Format
Follow these steps to display the formatting options:
1.
Insert the Reference diskette in drive A.
2. Turn on or reset the computer. The computer automatically
loads MS-DOS and displays the Operation Menu.
3. Press 2 to highlight Format hard disk and press
Enter. The Hard Disk Format Menu appears on the screen:
E-2
Physically Formatting a Hard Disk
The formatting options work as follows:
Format first scans the disk (if it has no defective track
table) for defective (bad) tracks and lets you decide which
tracks to mark as bad. Then the program formats the disk
and marks those bad tracks so they are never used to store
data.
Destructive surface analysis tests the
entire disk for read/write errors or unflagged bad tracks and
updates the defective track table. Because this option writes
and reads data on the disk, it destroys all data on any track
that produces an error. You cannot run the Destructive
surface analysis on a disk that has never been formatted.
Non-destructive surface analysis checks
the disk for unflagged bad tracks without destroying data.
You cannot run the Non-destructive surface analysis on a
disk that has never been formatted.
The type of format you choose depends on whether you are
reformatting a disk that has been used or formatting a new disk
for the first time. See the recommendations below.
Reformatting a Used Disk
If you are reformatting a disk you have been using that appears
to be damaged, follow these steps:
1. Use the Non-destructive surface analysis test to check for
unflagged bad tracks.
2.
If errors occur during the Non-destructive analysis, use
BACKUP to back up the data on your disk. (See your
MS-DOS Reference Manual for instructions on how to use
BACKUP.)
3. Run the Destructive surface analysis.
Physically Formatting a Hard Disk
E-3
Formatting a New Disk
Many hard disk drives come with a printed list of bad tracks but
without the bad tracks flagged on the disk. Other hard disks
(such as those supplied by Epson) come with the bad tracks
already flagged. If you are formatting a new hard disk that has
never been formatted, select the l-Format option to format
the disk.
Selecting an Option
When using this program, you often need to select an option
from a menu. There arc two ways to do this:
You can use the arrow keys
to move the
highlighted cursor block to the option and press Enter.
You can type the number of the option and press Enter.
You can select almost any option that appears on the screen
while you are formatting the disk using either of these two
methods. Therefore, when the instructions in this appendix tell
you to select an option, you can either use the arrow keys (
) to highlight the option or you can type the number of
the option. Then press Enter. (You must press Enter to start
the operation.)
Starting the Formatting Process
If you have more than one hard disk drive, you see this prompt:
Enter

(If the disk already has a defective track table, you do not see
the message because the disk does not need to be scanned for
bad tracks.)
Select Y to scan the disk or N to skip the scanning process.
If you select Y, the program scans the disk and displays these
messages during the process:
Scanning for flagged bad tracks...
Head : nnn
Cylinder : nnnnn
You see the head and cylinder numbers decrease as the program
progresses. After scanning the disk, the program displays the
results, such as the following:

2. Type the number of the cylinder containing the bad track
and press Enter. You see this prompt:
Enter head number (0 - nn ):
3. Type the head number for the bad track and press Enter.
To cancel the operation, press Enter without typing a value.
When you complete a valid entry, it appears in the table and
you can add the next bad track, if necessary.
If you make a mistake, move the cursor block to the incorrect
track and press C to alter the track data or press D to remove
the track from the table. Change the track data just as you add a
track.
The maximum valid cylinder number and head number (nnnn
and nn) vary according to the capacity of the hard disk. If you
enter an invalid cylinder or head number, a reminder of the
range of values appears and the program asks you to enter the
value again.
When you finish adding all the bad tracks, press Enter without
typing a value. After you complete editing, check the entries in
the defective track table. When you are sure the table is correct,
press F. The program displays a warning about the consequences
of proceeding with formatting.
