cl
512KB or 1MB of on-board video memory (512KB systems
are expandable to 1MB)
CI
Math coprocessor built into the 486DX/33 and 486DX2/50
microprocessor chips
cl
Built-in VGA port
0
Two built-in serial ports and one built-in parallel port
Ll
Built-in IBM® PS/2™ compatible keyboard and mouse ports
cl
Four 16-bit (or 8-bit) ISA option slots
Cl
Support for up to three internal mass storage devices
CI
Password security.
The shadow RAM feature allows your system to speed up
processing by moving the system and video BIOS into the RAM
area of memory.
Introduction 1
Using the built-in interfaces, you can connect most of your
peripheral devices directly to the computer so you don’t have
to install option cards. You can use the option slots to enhance
your system with extra functions such as a modem card or
additional interface ports.
The VGA controller supports standard resolutions up to
640 x 480 in 16 colors and extended resolutions up to 1024 x 768
in 16 colors (interlaced and non-interlaced), and lower
resolutions in up to 256 colors. With 1MB of video memory
installed, the VGA controller supports resolutions up to
1024 x 768 in 256 colors and 640 x 480 in 16.8 million colors
(for some applications).
VGA Utilities
Your computer comes with special MS-DOS® VGA drivers and
utilities for use with the integrated VGA interface. With these
utilities, you can take advantage of extended VGA features
such as high resolutions and 132-column text mode when you
run popular application programs. See the VGA Utilities Guide
for installation instructions.
Optional Equipment
You can easily upgrade your computer by installing additional
memory and a wide variety of options, as described below.
(Installation instructions are provided in Chapters 2 and 3 of
this manual.)
Memory
By adding lMB, 4MB, or 16MB SIMMs (single inline memory
modules) to the main system board, you can expand the
computer’s memory up to 32MB.
2 Introduction
Drives
Your system can support up to three internal mass storage
devices, including hard disk drives, diskette drives, a tape
drive, or a CD-ROM drive. As your storage needs expand, you
can install additional drives.
Over Drive Processor
Depending on which system you have, you may be able to
®
enhance your system by installing an Intel OverDrive™
processor. This processor doubles the internal clock speed so
your system runs much faster.
Math Coprocessor
If you have the 486SX/25, you may want to install an 80487SX,
25 MHz coprocessor. This optional microprocessor includes a
built-in math coprocessor so your computer can perform
mathematical functions faster.
AIternate VGA lnterface
If you want to install a high-resolution graphics adapter card
for additional graphics capabilities (such as 1280 x 1024
resolutions), you can connect it to the computer’s alternate
VGA interface. This allows you to use the special graphics
features on the adapter card while accessing the standard VGA
signals provided by your main system board.

Do not connect or disconnect any peripheral device cables
(including the mouse or keyboard) or power cables when
the computer’s power is on.
Never turn on the computer with a protective card in a
5.25-inch diskette drive.
Never turn off or reset your computer while a disk drive
light is on. This can destroy data stored on the disk.
Always wait at least 20 seconds after you turn off the
power before you turn it on again. This prevents possible
damage to the computer’s electrical circuitry.
Do not leave a beverage near your system. Spilled liquid
can damage the circuitry of your equipment.
Follow these steps to turn on your system:
1. Turn on the monitor, printer, and any other peripheral
devices connected to the computer.

2. If you do not have a hard disk, insert your main operating
system diskette in drive A.
Note
If you do not have a hard disk, you need to insert the
operating system diskette each time you turn on your
system so the computer can copy the operating system
to its memory. See your operating system manual for
more information.
3. To turn on the computer, press the power button located on
the right side of the front panel, as shown below.

The power indicator lights up. After a few seconds, the
computer displays a count of its system memory, and then
performs its power-on diagnostics. This is a series of checks the
computer runs each time you turn it on to make sure
everything is working correctly. (If necessary, use the controls
on your monitor to adjust the screen display.)
Using Your Computer
1-3
If you have made a major change to your system, such as
adding a disk drive, the computer may take a few minutes to
complete power-on diagnostics the first time you turn it on.
When the system has successfully completed its diagnostics,
you see the following prompt:
Press Del to start SETUP
Note
If your computer’s configuration does not match the
information stored in the computer’s CMOS RAM (defined
through the SETUP program), you see an error message.
Press [Delete) to run the SETUP program to correct the
information. (See Chapter 2 of the Setup Guide for
instructions.)
If you do not want to run SETUP, do nothing. After about five
seconds your computer either loads the operating system from
the hard disk or the diskette in drive A or, if you’ve set a
System Access password, it prompts you for your password.
When you enter the correct password, your computer loads the
operating system.
What happens next depends on how your computer is set up.
If your system is configured to automatically load a program
(such as Microsoft@ Windows@ or a word processing program),
you see the first menu or screen display of that program. If not,
you may see the operating system prompt, such as C : \> or A>.
See your application program manuals for further instructions.

Turning Off the Computer
Whenever you turn off your system, follow these steps:
1. Save your data and exit any application program you are
using.
2. Check the hard disk drive light and the diskette drive light(s)
to make sure they are not on. Do not turn off the computer
if a drive light is on, because you can damage the drive or
lose data.
3.
Remove any diskette(s) from the diskette drive(s).
4.
Press the power button to turn off the computer and then
turn off any peripheral devices (monitor, printer, etc.).
Using Disks and Disk Drives
The disk drives in your computer allow you to store data on
disk, and then retrieve and use your stored data. This section

How Disks Store Data
Diskettes are made of flexible plastic coated with magnetic
material. This plastic is enclosed in a square jacket that is either
hard (M-inch diskette) or slightly flexible (5.25-inch diskette).
Unlike a diskette, a hard disk is rigid and fixed in place. It is
sealed in a protective case to keep it free of dust and dirt. A
hard disk stores data the same way that a diskette does, but it
works much faster and has a much larger storage capacity.
All disks are divided into data storage compartments by sides,
tracks, and sectors. Double-sided diskettes store data on both
sides. On each side are concentric rings, called tracks, on which
a disk can store data.
A disk is further divided by sectors, which can be visualized as
pie slices. The illustration below provides a simple
representation of tracks and sectors.
1-6
Using Your Computer
Double-sided and high-density diskettes have 80 tracks on each
side and double-sided, double-density diskettes have either 40
or 80 tracks on each side. Diskettes can have 8, 9, 15, or 18
sectors per track.
A hard disk consists of two or more platters stacked on top of
one another and thus has four or more sides. In addition, a hard
disk has many more tracks per side than a diskette, but the
number of tracks depends on the capacity of the hard disk. The
number of sectors depends on the type of hard disk.
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 to the position under the read/write head
where the data is to be written. A diskette has an exposed area
where the read/write head can access it.
Because data is stored magnetically, you can retrieve it, record
over it, and erase it just as you play, record, and erase music on
a cassette tape.
Types of Diskette Drives
The following list describes the types of diskette drives you can
use in your computer and which diskettes to use with them:
0
1.44MB drive-Use 3.5-inch, double-sided, high-density,
135 TPI, 144MB diskettes. These diskettes contain 80 tracks
per side, 18 sectors per track, and hold up to 1.44MB of
information (approximately 600 pages of text).
Note
MB stands for megabyte, which equals 1024KB (or
1,048,576 bytes). KB stands for kilobyte, which equals
1024 bytes. Each byte represents a single character, such
as A, $, or 3.
Using Your Computer
1-7
1.2MB drive-Use 5.25-inch, double-sided, high-density,
96 TPI, 1.2MB diskettes. These diskettes contain 80 tracks
per side, 15 sectors per track, and hold up to 1.2MB of
information (approximately 500 pages of text).
720KB drive-Use 3.5-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 (approximately 300 pages of text).
360KB drive-Use 5.25-inch, double-sided, double-density,
48 TPI, 360KB diskettes. (You can also use single-sided,
160KB or 180KB diskettes.) These diskettes contain 40
tracks per side and 8 or 9 sectors per track. With 8 sectors
per track, a diskette holds up to 320KB. With 9 sectors per
track, a diskette holds up to 360KB of information
(approximately 150 pages of text).
Note
You must format a new diskette before you can store data on
it. See “Formatting Diskettes,” later in this section.
Drive and diskette incompatibilities
If your computer has more than one type of diskette drive, or if
you use different types of diskettes, you need to be aware of
certain incompatibilities between the drives and diskettes. See
the following tables.

5.25-inch drive/diskette compatibility
If you write to this diskette in a 1.2MB drive, you may not be able to read it
or write to it in a 360KB drive later.
Because of possible incompatibilities, always indicate the
diskette type and density when you label your diskettes.
(Usually this information appears on the manufacturer’s label.)
Note
If you want to format a 720KB diskette in a l&MB drive or a
360KB diskette in a 1.2MB drive, make sure you include the
correct parameter in your format command. See your
operating system manual for instructions.
If you have any combination of the above drives (1 &MB,
1.2MB, 720KB, or 360KB) and you are using MS-DOS, you can
copy files from one drive to another-using COPY or
XCOPY-as long as the correct diskette type is in each drive.
You can also use these commands to copy files between a hard
disk and any type of diskette. However, you cannot use the
MS-DOS DISKCOPY command to copy from one diskette drive
to another if the two drives are not the same type. For more
information, see your operating system manuals.

Caring for Diskettes and Diskette Drives
Follow these basic precautions to protect your diskettes and
avoid losing data:
0 Remove all diskettes before you turn off the computer.
If you have a diskette that contains data you
don’t want to accidentally write over or erase,
be sure you write-protect it. This is especially
important for your operating system and
application program diskettes. See “Writeprotecting Diskettes,” below, for more details.
Cl Do not remove a diskette from the diskette drive or reset or
turn off the computer while the drive light is on. This light
indicates that the computer is copying data to or from a
diskette. If you interrupt this process, you can destroy data.
Keep diskettes in a moderate environment.
Don’t leave them sitting in the sun or in
extreme cold or heat because this can destroy
the data.
Q 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.
Keep diskettes away from magnetic fields,
such as those generated by electrical
appliances, telephones, and loudspeakers.
(Diskettes store information magnetically.)
l-10
Using Your Computer
CI
Do not place diskettes on top of your monitor or near an
external hard disk drive.
Always hold a 5.25-inch diskette by its
protective jacket and never touch the magnetic
surface (exposed by the read/write slot). The
oils on your fingertips can damage it.
Q Never wipe, brush, or try to clean diskettes in any way.
Write on a diskette label before you attach it to
the diskette. If you need to write on a label that
is already on the diskette, use only a soft-tip
pen-not a ballpoint pen or a pencil.
0 Carefully label your diskettes and indicate the type and
density. Do not stick several labels on top of one another;
this can make it difficult to insert and remove the diskette
in the drive.
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.
CI
Do not place anything on top of your diskettes, and be sure
they do not get bent.
Using Your Computer
l-11
Write-protecting Diskettes
You can write-protect a diskette to prevent its data from being
altered. When a diskette is write-protected, you can read it and
copy data from it, but you cannot store new data on it or delete
any files it contains.
On a 3.5-inch diskette, the write-protect device is a small switch
on the back of the diskette in the lower right comer, shown
below. To write-protect a 3.5-inch diskette, slide the switch
toward the edge of the diskette until it clicks into position,
exposing a hole in the comer.
To remove the write protection, slide the switch toward the
center of the diskette until it clicks into position and the hole is
covered.
Note
A high-density 3.5-inch diskette has an additional hole on
the opposite side. This hole does not affect the writeprotection.
1-12
Using Your Computer
To write-protect a 5.25-inch diskette, cover the small,
rectangular notch (shown below) with an adhesive
write-protect tab. Write-protect tabs usually are included in a
new package of blank 5.25-inch diskettes.
To remove the write protection, peel off the write-protect tab.
Note
Some program diskettes have no switch or notch so they are
permanently write-protected. This protects them from being
accidentally erased or altered.

proper location, such as a diskette container.
Using Your Computer
1-15
Caution
Never remove a diskette or reset or turn off the computer
while a diskette drive light is on. You could lose data. Also,
remove all diskettes before you turn off the computer.
Using a Single Diskette Drive System
Most operating systems expect the computer to have at least
two diskette drives and display prompts and messages
accordingly. MS-DOS, for example, recognizes the first diskette
drive (the top drive) as drive A and a second diskette drive as
drive B. If you have only one diskette drive, MS-DOS can treat
it as both A and B when you need to perform operations that
normally would use two diskette drives.
For example, if you enter a command to copy data from A to B,
MS-DOS copies the data from the first diskette you place in the
drive (which would be drive A) to the computer’s memory.
Then MS-DOS prompts you to insert another diskette (for
drive B) and copies the data from memory to the new diskette.
When copying is complete, you see a prompt to insert the
original diskette (A).
Because you may often swap diskettes this way, it is important
to remember which diskette is which. It is also a good idea to
write-protect your original diskette. (See “Write-protecting
Diskettes,” above.)
If you have a hard disk and one diskette drive, you can load the
operating system and application programs from the hard disk,
create and store your data there, and use the diskette drive just
for copying data to or from diskettes.
1-16
Using Your Computer
However, if you have only one diskette drive and no hard disk,
you need to use that drive to load the operating system as well
as any application program you are using. First, insert the
operating system diskette in drive A and load the operating
system; this copies it to the computer’s memory (RAM) so you
do not need to leave the system diskette in the drive. Then
remove the system diskette and insert your application
program diskette to load that data into memory, too. See your
application program manual for detailed instructions.
Formatting Diskettes
Before you can store data on a new diskette, you must format it.
Formatting prepares the diskette so that the operating system
can write data on it. You need to do this only once, before you
use the diskette for the first time.
You can also reformat previously used diskettes to store new
data. This process erases all the data on the diskette, so be sure
you do not want to save any of the files on a used diskette
before you format it. See your operating system manual for
instructions on formatting diskettes.
Making Backup Copies
It is important to make copies of all your data and system
diskettes. Make backup (or working) copies of all diskettes that
contain programs, such as your operating system, Reference,
and Utility diskettes; then use only the copies. Store the original
diskettes away from your working diskettes. Also, copy your
data diskettes regularly, whenever you revise them, and store
them away from your originals.
If you have a hard disk, you’ll probably use it to store the
programs and data files you use regularly. Keep backup copies
of all your files on diskettes or tapes (if you have a tape backup
drive).
Using Your Computer
l-17
Using a Hard Disk Drive
Using a hard disk is similar to using a diskette. However, the
hard disk provides several advantages:
An 80MB hard disk can store as much data as
approximately sixty-six 1.2MB diskettes or fifty-five 1.44MB
diskettes, and a 120MB hard disk can store about a third
more. A 240MB hard disk can store the equivalent of two
hundred 1.2MB diskettes or one hundred sixty-six 1.44MB
diskettes.
Your computer can perform all hard disk 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.
Most operating systems let you keep related files together in
directories and subdirectories so they are easy to find and use.
See your operating system manual for instructions on
managing your files and directories.
Note
A hard disk must be partitioned and formatted before you
can use it. Be sure you have performed the procedures
described in your operating system manual to prepare your
hard disk for use.
1-18
Using Your Computer
Backing up the hard disk
While the hard disk is very reliable, it is essential to back up
your hard disk files to diskettes or tapes in case you lose some
data accidentally. Make copies of all your system and
application program diskettes before copying the programs to
the hard disk. After you create data files on the hard disk, be
sure to copy them whenever you revise them to keep your
backup diskettes or tapes up-to-date.
Caring for your hard disk
Follow these precautions to protect your hard disk drive from
damage and to avoid losing data:
Never turn off or reset the computer when the hard disk
access light is on. This light indicates that the computer is
copying data to or from the hard disk. If you interrupt this
process, you can lose data.
Never attempt to open the hard disk drive. The disk itself is
enclosed in a sealed container to protect it from dust.
If you need to move your computer, you may need to run
the HDSIT program to prepare the hard disk for moving, as
described on page 1-26.

Resetting the Computer
Occasionally, you may want to clear the computer’s current
settings or its memory without turning it off. You can do this
by resetting the computer.
For example, if an error occurs and the computer does not
respond to your keyboard entries, you can reset it to reload
your operating system and try again. However, resetting erases
any data in memory that you have not saved; so reset only if
necessary.
Caution
Do not reset the computer to exit a program. Some programs
classify and store new data when you exit them in the
normal manner. If you reset the computer without properly
exiting a program, you may lose data.
To reset the computer, the operating system must be either on
the hard disk or on a diskette in drive A; so if you do not have a
hard disk, insert the system diskette in drive A. If you are using
MS-DOS, hold down (T) and (71 and press IBlete_]. The
screen goes blank for a moment and then the computer should
reload your operating system.
If resetting the computer does not correct the problem, you
probably need to turn it off and reboot it. Remove any
diskette(s) from the diskette drive(s). Turn off the computer
and wait 20 seconds. If you do not have a hard disk, insert the
system diskette in drive A. Then turn on the computer.

Changing the Processor Speed
Your computer’s processor can operate at two speeds: high
or low. High speed is the highest speed at which your
microprocessor is capable of running, such as 25,33, or
50 MHz. Low speed simulates an 8 MHz processor to provide
compatibility with older application programs.
Note
When your computer is operating at high speed, the SPEED
light on the front panel is green. When the computer is
operating at low speed, the light is amber.
You should use high speed for almost everything you do
because your programs will work faster. However, certain
application programs have specific timing requirements and
can run only at the slower speed. See your software manual to
determine if this is the case.
Some copy-protected programs require the computer to run at
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, you can change the
speed to low to access the diskette and return it to high speed
when you are finished.
1-24
Using Your Computer
You can change the processor speed temporarily by entering
one of the following commands from the numeric keypad on
your keyboard:

Using Your Computer
1-25
Preparing the Hard Disk for Moving
If you need to move your computer to a new location, you may
want to run the HDSIT program provided on your Reference
diskette to protect the hard disk during the move.
HDSIT moves (or parks) the disk drive’s read/write heads to a
region on the disk surface that does not contain data, and locks
them securely in position. This protects the hard disk from
being damaged if the computer is bumped accidentally.
Many hard disk drives, including all Epson drives,
automatically park their heads when you turn off the computer.
If your hard disk drive does not do this, or if you are not sure
that it does, be sure to run HDSIT.
If you have not already done so, copy the HDSIT.COM and
HDSIT.VER files from the Reference diskette to the root
directory on your hard disk. Then, when you want to run
HDSIT, type HDSIT and press [G).
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
then locks the heads and disables the keyboard. Remove any
diskettes and turn off the computer. Now you can move it to
the new location.
Caution
Whether you use HDSIT or not, always turn off your
computer and wait at least 20 seconds before you move it.
This allows your hard disk drive’s read/write heads to move
away from the disk to a safe location. If you move your
computer before this happens, you could damage your hard
disk drive.
1-26
Using Your Computer
Using AUTOEXEC.BAT and Other Batch files
If you are using MS-DOS to access your application programs,
you may find that there are commands you need to run
frequently. You can automate the execution of these commands
by listing them in a special file called a batch file. When you
type the name of the batch file and press [=I, MS-DOS
executes the commands in the file just as if you had typed each
command from the keyboard.
If you have a word processing program that can save a file as a
text-only file (sometimes called an ASCII file), you can use it to
create a batch file. You can also use the MS-DOS COPY, EDIT,
or EDLIN command, or a text editor, to create the file.
One batch file that you may find particularly useful is called
AUTOEXEC.BAT. Every time you turn on your computer,
MS-DOS looks for the AUTOEXEC.BAT file and automatically
executes each of the commands in the file.
When you install MS-DOS, it creates an AUTOEXEC.BAT file
for you, which you can modify or replace as described above.
Be sure to name the file AUTOEXEC.BAT and store it in the
root directory of the hard disk or diskette from which you load
MS-DOS. (You may want to rename your original file to
AUTOEXEC.OLD, in case you need to use it again later.)
See your MS-DOS documentation for more information about
creating and using batch files.

Installing and Removing Options
You can enhance the performance of your computer by adding
optional equipment such as memory modules, option cards, or
an Intel OverDrive processor.
Memory modules-also called SIMMs (single inline memory
modules)-allow you to increase the amount of memory in
your computer.
An option card is a circuit board you install in your computer
to add a particular function, such as a modem or an additional
interface port.
An OverDrive processor is a CPU chip which doubles the
internal processing speed of the microprocessor and includes a
built-in math coprocessor. If you have the 486SX/25 or
486DX/33 system, you can install an OverDrive processor on
your system board to provide this increased performance.
(Alternatively, on the 4865X/25 system you can install a
487SX/25 chip to provide math coprocessor support.)

lnstalling an Option Card
This section explains how to install an option card in your
computer. Your computer has four option slots to
accommodate up to four B-bit or 16-bit option cards.
Usually it does not matter which slot an option card occupies as
long as the card fits in the slot. For example, you can place
some B-bit cards in a 16-bit slot. However, follow these
guidelines when deciding which slot to use:
If you have an B-bit card that has an additional tab along
the bottom, it will not fit in any of the option slots in your
computer.
If you are installing a high-resolution graphics adapter
card, follow the instructions below to install the adapter
card; then see “Using the Alternate VGA Interface” on page
2-26 to connect the card to the VGA feature connector in
your computer.
You may not be able to install a half-length or full-length
option card in the slot closest to the system board (Slot 1).
However, you can install one that is no longer than 110 mm
(4.4 inches).

lnstalling a
New Processor Chip
If you have a 486SX/25 or 486DX/33 system, you can enhance
your system’s performance by installing an Intel OverDrive
processor. Alternatively, for the 486SX/25, you can install a
487SX/25 microprocessor with built-in math coprocessor.
Complete instructions for installing the processor are provided
in the manual that comes with it. Please follow those
instructions carefully, along with the following guidelines:
Although the OverDrive processor User’s Guide instructs
you to remove the main system board from the computer,
this is not necessary. You can leave the board inside the
computer case while you install the processor.
Refer to the illustration on page 2-3 to locate the
microprocessor socket on the system board. If this socket is
empty, you can install the OverDrive processor (or 487SX
chip) directly in the socket. If it contains the CPU chip, you
need to remove it before you install the new processor.
If you need to remove the existing microprocessor, lift the
lever to release the CPU chip. After you install the new
processor, push the lever down to secure it in the socket.
If you install an OverDrive processor or the 487SX/25 chip,
you may need to change the settings of the jumpers J10
through J12, as described on page 2-7. If you install the
OverDrive processor in an empty socket, you need to
change the jumper setting of J23 to position 2-3 as well.
After you install the processor and replace the computer’s
cover, run the SETUP program so your computer can
update its configuration. See Chapter 2 of the Setup Guide
for instructions. (You need only run the program and save
the configuration; you do not need to change any settings.)

Using the Alternate VGA interface
Your computer includes an alternate VGA interface (feature
connector) on the main system board. This connector allows
you to install a high-resolution graphics adapter card in one of
the computer’s option slots and still access the standard VGA
signals provided by your system circuitry.
Typically, high-resolution graphics adapter cards increase the
graphics processing performance of your VGA monitor and
provide resolutions of more than 1024 x 768. They are useful for
high-end graphics applications such as AutoCAD® or Windows.
To connect the graphics adapter card interface to the alternate
VGA interface on your main system board, you must have a
VGA feature cable.

Using a Display Adapter Card
If you are not using a VGA monitor or if you want to install an
optional display adapter card instead of using the built-in
adapter to control your VGA monitor, read the guidelines in
this section.
Before you can connect a monitor to a display adapter card,
you must install the card in your computer. If it is not already
installed, follow the instructions on page 2-16 to install an
option card.
When installing the card, make sure any switches or jumpers
on the card are set properly. For example, you may need to
change a switch setting to select the refresh rate. See the
documentation that came with your monitor and display
adapter card for instructions.
If you install an optional display adapter card, you must set
jumper J6 on the main system board to position 2-3 to disable
the built-in VGA port. (You do not have to do this if you
connected the card to the VGA feature connector on the main
system board.) You also need to set jumper J5 to the On
position if you are using a CGA adapter and monitor. See
page 2-6 for instructions on changing jumper settings.
Note
If you install a high-resolution graphics adapter card that
connects to an alternate VGA interface (also called a “feature
connector”), see page 2-26 for instructions on connecting the
card to the connector on the main system board.
After you install the card, connect your monitor to the
computer. If your monitor came with its own manual, follow
the instructions there. Otherwise, just insert your monitor
connector into the adapter card port instead of the built-in port.

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

Installing and Removing Drives
1. Locate the diskette drive ribbon cable. One end of the cable is
connected to the system board. If you are installing a
second diskette drive in the lower horizontal drive bay, the
other end of the cable is connected to the top diskette drive;
use the middle connector. If you are installing a diskette
drive in the upper bay, use the free end connector.
The diskette drive connector that extends from the back of the
drive has gold contacts on both sides. Grasp the cable
connector and align it with the drive connector so that the
key-way (the plastic divider) in the cable connector lines up
with the gap in the drive connector, as shown below.

Formatting a Hard Disk
This chapter describes how to low-level (or physically) format
a hard disk. This procedure should not be confused with the
logical format performed by your operating system. The
physical formatting of a hard disk is a separate step that is
usually done at the factory by the disk manufacturer.
If your computer came with a factory-installed hard disk, or if
you installed an optional Epson IDE hard disk, it has already
been physically formatted. (All IDE drives come formatted.)
You may need to use the procedure in this chapter to physically
format a hard disk if you installed a non-Epson hard disk in
your computer that has never received the low-level format
and did not come with its own format utility. If you installed a
hard disk that came with its own format utility, use that
program to physically format the disk.
Caution
Physically formatting a hard disk erases any data it contains.
Be sure to back up any data on your hard disk before you
format it. If you are unsure whether formatting is necessary,
contact your Epson Servicer or call the Epson Connection
(800-922-8911) for assistance.
In addition to destroying all the data on the hard disk,
formatting removes any partitions and logical formatting
defined on the disk by your operating system. After you
physically format a new or used hard disk, you need to
logically format the disk again using your operating system.
Formatting a Hard Disk
5-1
Starting the Program
Follow these steps to start the hard disk formatting program:
1. Insert the Reference diskette in drive A and log onto drive A.
2.
Type HDFMTALL and press [El. You see the Hard Disk
Format Menu:
1 - Format
2 - Destructive surface analysis
3 - Non-destructive surface analysis
0 - Exit
The option you choose depends on whether you are
formatting a new disk or reformatting a used disk. The
options work as follows:
Q
Format first scans the disk for defective (bad) tracks (if
it has no defective track table) and lets you decide
which tracks to mark as bad. Then it formats the disk
and marks the bad tracks so they are never used to
store data.
CI 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 this test
on a disk that has never been formatted.
0 Non-destructive surface analysis checksthe
disk for unflagged bad tracks without destroying data.
You cannot run this test on a disk that has never been
format ted.
5-2
Formatting a Hard Disk
Formatting a New Disk
To format a new hard disk that has never been formatted, select
the Format option. You may need to modify the defective track
table to add bad tracks when you format the disk. Many hard
disk drives come with a printed list of bad tracks, but the bad
tracks are not flagged on the disk. Other hard disks (such as
Epson disks) come with the bad tracks already flagged.
Reformatting a Used Disk
To reformat a disk you have been using, follow these steps:
1. Use the Non-destructive surface analysis option to check for
unflagged bad tracks.
2. If errors occur during the Non-destructive surface analysis,
back up your hard disk to diskettes.
3. Run the Destructive surface analysis option to update the
defective track table.
4. Run the Format option to format the disk.
Selecting an Option
When you use this program, you often need to select an option
from a menu. There are two ways to do this:
0 Use the arrow keys ([r), (J-1, [t), [T) ) to
highlight the option and press [=I.
Ll Type the number of the option and press [=I.
You can select almost any option that appears on the screen
using either method.

2. Next you see the following prompt:
Accept recommended skewed sectors in
format : 1 ? (Y/N)
For an Epson hard disk drive, it is best to accept the
recommended skewed sector (also called the interleave
factor) of 1, since this setting allows your drive to perform
more efficiently. For other hard disk drives, you may need
to change this value if the documentation that came with
the disk recommends a different number.
To accept the default, select Y. Then go to step 3.
To enter a new value, select N. You see the following prompt:
Enter new skewed sectors in
format (l-16):
Enter the recommended number, which equals the maximum
sector number for the drive minus 1. Then press (Enterl,
3. Next you see this prompt:
Accept recommended skewed sectors per
head in format : 0 ? (Y/N)
For an Epson hard disk drive, accept the recommended value
of 0. For another type of drive, use the value recommended
in the documentation for the drive.
To accept the default, select Y. Then go to step 4.

track and press m to change the track data or m to delete the
track from the table. Change the track data in the same way 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. Then check the entries in the defective track
table. When you are sure the table is correct, press m. The
program displays a warning about the consequences of
proceeding with formatting, as described in the next section.

Option 2, Destructive Surface Analysis
You can perform a Destructive surface analysis of your hard
disk to accurately locate any bad tracks and flag them, if they
are not flagged. The test writes, reads, and verifies information
on every track, except those that are already flagged as bad.
Caution
If any errors occur during this check, all data on the track
that caused the error is destroyed. If you think that an
unflagged bad track is causing trouble, first run the
Non-destructive surface analysis to check the disk surface.
To start this test, select Destructive surface analysis
from the Hard Disk Format Menu. You see these messages:

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 chapter. 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
diagnostic checks on the various components of your system.
See Chapter 4 for instructions. If the suggestions here or in
Chapter 4 do not solve the problem, contact your Authorized
Epson Servicer or call the Epson Connection at (800) 922-8911.
ldentifying Your System
When you request technical assistance, be ready to provide
the serial number of your computer, its system BIOS version
number, its configuration (including the type of disk drives,
monitor, and option cards), and the names and version
numbers of any software programs you are using.
You may have recorded this information on the Read This First
card that came with your system. If not, you can find the
computer’s serial number on its back panel. If you are able to
use your computer, follow the steps below to obtain
information about your configuration, as well as your system
BIOS and MS-DOS (or other operating system) version number.
Troubleshooting 6-1
1. Turn on your computer.
2. When the computer performs its power-on memory test,
the version number of your video BIOS appears at the top
of the screen. Next, the system BIOS version number
appears in a window at the bottom of the screen. Quickly
write down these version numbers. If you do not have
enough time to do this, press [ctrl)
Ait [E] and try
ii
again.
3. When you see Press Del to start SETUP, press [El.
Write down the necessary configuration information shown
on the SETUP screens; then exit SETUP without changing
your configuration. (See Chapter 2 of the Setup Guide for
instructions.)
4. If you are using MS-DOS, at the command prompt type VER
and press Enter . The screen displays the MS-DOS version
number. Write it down. (If you are using another operating
system, see the manuals that came with it for instructions
on obtaining the version number.)
Error Messages
Your computer’s built-in memory (ROM) contains a series of
diagnostics programs, called power-on diagnostics, which your
computer runs automatically every time you turn it on. These
programs check internal devices such as ROM, RAM, the timer,
the keyboard controller, and the hard disk drive.
6-2 Troubleshooting
What the system does when it encounters an error depends on
how you’ve set the Halt on option in the SETUP program.
(See Chapter 2 of the Setup Guide for instructions on using the
SETUP program.) With this option, you can tell the computer to
halt system initialization when it detects the following types of
errors:
Q All errors
CL
All errors, except diskette drive and keyboard errors
0 All errors, except diskette drive errors
0 All errors, except keyboard errors
0 No errors.
If the system detects an error you’ve told it to ignore through
the SETUP program, system initialization begins as though the
system had not detected an error.
When the system detects an error that isn’t serious, such as an
incorrectly defined diskette drive, you see the error message
and the following prompt:
Press Fl to continue or Del to start SETUP
Write down the error message and press CT] to continue.
If the system detects a serious error or an error you’ve
identified as a “halt on” error, the computer cancels further
checking and halts system initialization. The error message
remains on the screen and the computer locks up. If this
happens, see “The Computer Won’t Start” in this chapter. If
none of the suggestions listed there solves the problem, contact
your Authorized Epson Servicer as soon as possible. Report
any error messages when you request technical assistance.
Troubleshooting 6-3
The following table lists error messages that may appear
during power-on diagnostics. If you receive an error message,
look it up in the table below; it directs you to the proper

Power-on diagnostics error messages (continued)
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? If not, remove any diskettes and turn
off the power. Make sure the power cord is securely
connected to both the AC inlet on the back panel and an
electrical outlet. Replace your main operating system
diskette or Reference diskette, if necessary, and turn on the
computer again.
Caution
If you turn off the computer, always wait at least 20
seconds before turning it back on. This prevents damage
to the computer’s electrical circuitry.
6-6 Troubleshooting
2. If the power light still does not come on, check the electrical
outlet for power. Turn off your computer, unplug the
power cord, and plug a lamp into the outlet. Turn it on to
see if the outlet supplies power.
3. If you installed or removed any of your system components,
such as a disk drive, check to make sure you have
reconnected all the internal and external cables correctly.
See Chapters 2 and 3 for instructions.
4. If the electrical outlet is working and all the connections are
secure but your computer still won’t start, call your
Authorized Epson Servicer.
Note
If the computer starts but you can’t see anything on the
screen, see “Monitor Problems” on page 6-13.
The Computer Does Not Respond
If your computer locks up and does not respond when you
type on the keyboard, follow these steps:
1. Wait a few moments; some operations take longer than others
to complete. For example, the computer takes longer to sort
a database than to display the time. If your computer still
does not respond after a reasonable length of time, proceed
to the next step.
Troubleshooting 6-7
2. If you have just made a change in your system configuration,
your computer may take a few minutes to complete its
power-on diagnostics. The first time you turn on your
computer after making such a change, it can take several
minutes to finish its self test, depending on what you
changed. If the computer does not display the operating
system prompt after five minutes, turn off the computer,
wait 20 seconds, and try again. If that doesn’t work, turn off
the computer, insert your main operating system diskette
or Reference diskette in drive A and turn on the computer.
If it still does not boot, contact your Authorized Epson
Servicer.
3. Did you enter the correct password? See “Password
Problems” below.
4. Could your software be causing the problem? If you are
running an application program, see “Software Problems”
later in this chapter.
5. The problem could be caused by your keyboard. See
“Keyboard Problems” later in this chapter.
6. If you want to stop whatever the computer is doing and
return to the MS-DOS command prompt, hold down the
[T] key and press (Break] (or Ic]). See Chapter 1 for more
information on-stopping a command or program.
7. If your computer still does not respond, you can reset it
m IAft] [E’ command. See “Resetting
using the p7
Your Computer” in Chapter 1 for more information.
8. If resetting the computer does not work, turn off the
computer and wait at least 20 seconds. If you do not have a
hard disk drive, insert your main operating system diskette
in drive A; then turn on the computer. It should load the
operating system.
6-8 Troubleshooting
9. If you installed a display adapter card (and did not connect it
to the feature connector on the main system board), you
must set jumper J6 to disable the built-in VGA adapter.
Otherwise, you will not see any display on the screen. See
“Changing the Jumper Settings” in Chapter 2.
10. If your computer suddenly stops operating, its power
supply thermal detection circuits may have detected
excessive operating temperatures and automatically shut
down the power. This protects your system from damage.
When these circuits detect a high temperature, they shut off
all the DC outputs in the power supply and cause it to go
into latch-off state. This does not damage the power supply,
but you must correct the temperature problem before you
can use your computer again. See “Restoring the Power
Supply” below.
Restoring the Power Supply
To restore normal power supply operation, follow these steps:
1. Turn off the computer and leave it off for at least
30 seconds to reset the power supply logic.
2. To determine the cause of the high temperature and correct
the condition, check for the following:
0
Room temperature above 90o F (32” C). If this is the
case, relocate the computer to a cooler area.
Ll
A blocked power supply fan. Make sure there is space
around the power supply fan vents in the back and
sides of the computer case. Remove the computer’s
cover and check both inside and outside the computer
for blockage. Make sure there is ample room around
your system for air circulation.
Troubleshooting 6-9
0 An overload of the power supply limitations. Check the
table in Appendix A to see if you have exceeded the
option slot power limits. See your option card
manual(s) for the power requirements for your option
card(s).
3. After you correct the problem causing the overheating,
allow the computer to cool down for at least five minutes at
room temperature (about 78” F or 25” C). This resets the
thermal detection circuits.
4. If you removed the computer’s cover, replace it now. (See
Chapter 2 for instructions.) Then turn on the computer.
If the power supply shuts off again, contact your Authorized
Epson Servicer.
Password Problems
If you have any trouble using your password, try the following:
1. If you think you know the correct password, reset the
computer and try again. See Chapter 1 for instructions.
2. If you know the current password but you want to change
or delete it, see Chapter 2 of the Setup Guide for instructions.
3. If you do not know the current password and you cannot
access your computer or use the SETUP program, see the
next section.
6-10 Troubleshooting
Accessing Your System
If you have forgotten your current System Access or Setup
Access password, follow these steps:
1. Turn off the computer.
2.
Follow the instructions under “Changing the Jumper
Settings” in Chapter 2 to disable the password function by
setting jumper J7 to On.
Caution
When you move J7 to the On position, all the settings
you changed using the SETUP program return to the
factory defaults. If you move this jumper, you must run
SETUP to update your system configuration again.
3.

your previous SETUP settings and restored the factory
default settings.)
11. Save your settings as you exit SETUP. (See Chapter 2 of the
Setup Guide for instructions.) The computer reboots.
If you disabled password security, you do not see the
password prompt and can access your computer immediately.
If you set a new password, you see the password prompt.
Enter your password as described in Chapter 1.
Keyboard Problems
If you have trouble with the keyboard, check the following:
1. If the screen displays a keyboard error message when you
turn on or reset the computer, make sure the keyboard is
securely connected to the correct port. See “Connecting the
Keyboard” in Chapter 1 of the Setup Guide for instructions.
2. If nothing happens when you type on the keyboard, see
“The Computer Does Not Respond,” above.
3. If the cursor keys on the numeric keypad do not work
properly, the num lock function may be on. When num lock
is on, the keys on the numeric keypad work only as
numbers. If the Num Lock light in the upper right comer of
the keyboard is lit, press NWO& to turn off the function.
6-12 Troubleshooting
If you want to change the initial setting of the num lock
function, see “Setting the NumLock Boot Status” in
Chapter 2 of the Setup Guide.
4. If you still have trouble with the keyboard, run the Keyboard
diagnostic test described in Chapter 4. If the diagnostics
indicate an error, contact your Authorized Epson Servicer.
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 its power light is lit. If the
power light is on but you still do not see anything on the
screen, check the 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 it back on.
Wait to see if the screen displays any text.
3. If you still do not see anything on the screen, make sure you
connected your monitor to the computer securely.
See “Connecting a Monitor” in Chapter 1 of the
Setup Guide or your monitor manual for instructions.
4. 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 outlet. Then plug a lamp into the wall
outlet and turn it on to see if the outlet supplies power.
5. If you installed a display adapter card, make sure your
monitor and display adapter match. Also check to see if
the card’s switches or jumpers are set properly. See “Using
a Display Adapter Card” in Chapter 2 and your monitor
and display adapter card manuals for instructions.
Troubleshooting 6-13
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 you have. Also make sure you are using the
appropriate monitor and display adapter for your software.
Note
If your application program requires a monitor that
supports graphics but you have a monochrome monitor,
the results will be unpredictable.

If you still have difficulty with your monitor, run the Video
adapter diagnostic tests described in Chapter 4. If the
diagnostics program indicates an error, contact the
representative who sold you the monitor.
6-14 Troubleshooting
Diskette Problems
If you see an error message or have trouble accessing data on a
diskette, try the following steps:
1. You may have inserted the diskette upside-down or it may
not be inserted all the way. Remove the diskette from the
drive and reinsert it. If the diskette drive has a latch, be sure
to turn it down to secure the diskette in the drive. See
Chapter 1 for detailed instructions on inserting and
removing diskettes.
2. If reinserting the diskette does not solve the problem and
you have access to another diskette drive of the same type,
place the diskette in the other drive and repeat the
operation. If you can read the diskette, 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.
For example, are you trying to read a 1.44MB diskette in a
720KB diskette drive? See “Types of Diskette Drives” in
Chapter 1 for more information.
4. If your diskette is the right type for your drive, see if it is
write-protected. On a 3.5-inch diskette, the write-protect
switch may be set to the write-protect position or there may
be no switch. On a 5.25-inch diskette, there may be a
write-protect tab over the notch on its side or there may be
no notch. You cannot alter data on a write-protected
diskette. (Some application programs do not function
properly if the diskette is write-protected. Check the
program manual.) See Chapter 1 for more information.
5. Is the diskette formatted? A new diskette must be formatted
before you can store data on it. See your operating system
documentation for instructions on formatting diskettes.
Troubleshooting
6-15
6. Did you receive one of the following MS-DOS error
messages?
Disk Drive Error: Abort, Ignore, Retry?
Disk error reading drive d:
Disk error writing drive d:
If you see one of these messages, make sure the diskette is
properly inserted in the drive. If the problem persists, try
removing the diskette and reinserting it.
If the error message still occurs, you may have a defective
diskette. Try copying the files from the bad diskette to a
new diskette.
7. If you see no error messages but there is something wrong
with the data in a file, the operating system or an
application program may have updated the storage
information on the diskette incorrectly. This is probably the
case if you have one of these problems:
Cl
Part of a file is missing
Ll A file includes parts of other files
D
An expected output file is missing.
If you are using MS-DOS use CHKDSK to make the necessary
repairs; see your MS-DOS documentation for instructions.
You may also have some special diagnostic software you
can use to check your diskettes.
6-16 Troubleshooting
Diskette Drive Problems
If you see a diskette error message or have difficulty with a
diskette drive, follow these steps:
1. If you have problems with a new diskette drive that someone
else installed for you, consult that person about the
problem.
2. If you installed the drive yourself, did you carefully follow
all the steps in Chapter 3? Review the instructions and
check all the cable connections to make sure you have
installed the drive correctly.
3. Did you run the SETUP program and configure the correct
type of diskette drive as part of your system? (See Chapter
2 of the Setup Guide for instructions.)
4. Try running the Diskette drive diagnostic tests described in
Chapter 4. If the diagnostics program indicates an error,
contact your Authorized Epson Servicer.
5. If the diskette drive is making loud or unusual noises, do not
attempt any further examination of it. Contact your
Authorized Epson Servicer.
Troubleshooting
6-17
Hard Disk Problems
If you have a problem with a hard disk, it could be the result of
improper installation, incomplete disk preparation, or
corrupted data. Consult one of the following sections,
depending on the problem you are having:
0 Installing the drive
0 Preparing the drive for use
0 Accessing data on the drive.
For example, if you could use the data on your disk in the past
but suddenly cannot, see “Accessing Data on the Drive.”
Caution
If your hard disk has data on it, always be sure to back up
your data before reformatting or repartitioning the drive.
lnstalling the Drive
If you have problems with a newly-installed drive, check the
following:
1. If someone else installed the drive, consult that person about
the problem.
2. If you installed the hard disk in your computer, did you
carefully follow all the instructions in Chapter 3? Review
the instructions, check all the cable connections, and check
the jumper settings on your drive.
6-18 Troubleshooting
3. If you installed an IDE hard disk drive, be sure you run
SETUP to update your configuration. Check to make sure
you selected the correct drive type and that you enabled the
built-in IDE hard disk drive controller. (If you connected
the IDE drive to a controller on an option card, be sure you
set the built-in controller to Disabled.) See Chapter 2 of
the Setup Guide for instructions.
4.
If you installed a non-IDE hard disk drive, was it
physically formatted by the manufacturer? A blank, new
hard disk must be physically formatted (or initialized)
before you can partition it and install an operating system
on it. This type of format is usually done by the
manufacturer; if yours was not, you must do it yourself.
If the drive came with its own format utility, use that
program; if not, follow the instructions in Chapter 5.
Note that a physical format is different from the softwarebased type of formatting commands (such as the MS-DOS
SELECT or FORMAT commands). See “Preparing the
Drive,” below, for more information.
Preparing the Drive
Before you can store data on a new hard disk (which has
already been physically formatted), you must do the following
to prepare it for use:
1. Run the SETUP program to define your hard disk as part of
the computer’s configuration. (See Chapter 2 of the Setup
Guide for instructions.)
2. Partition and format the drive for your operating system. If
you are using MS-DOS, instructions for performing these
procedures are provided in your MS-DOS manuals. If you
are using another operating system, follow the instructions
that came with it.
Troubleshooting
6-19
If you do not prepare the drive correctly, you cannot store data
on the disk. For example, if you partition the drive and format
it for MS-DOS (or for another operating system) but you do not
copy the operating system to the drive, you will not be able to
load the operating system from the hard disk.
If you are sure the hard disk was installed properly and you
prepared it for use as described above but you cannot access
the drive, review the instructions in your operating system
manuals. Make sure you performed each step in the installation
process correctly for your configuration.
Accessing Data on the Drive
If you have been using your hard disk drive successfully for
some time and notice a reduction in performance, the data on
the disk may have become fragmented. You may want to back
up all your data and then use a disk compaction utility to
reorganize the files on your disk. Many general utility
programs include a disk compaction utility.
If you still have trouble with your hard disk, you can back up
your data and physically reformat the disk. Then you’ll need to
reinstall the operating system and copy your files back onto the
disk. See Chapter 5 and your operating system manual for
instructions.
If you cannot access data on your hard disk or you are
receiving read/write errors, the disk may have a physical
problem. Contact your Authorized Epson Servicer.
6-20 Troubleshooting
Software Problems
If you have trouble with an application program, try the
following:
1.
If the application program does not start, check that you are
following the correct procedure for starting the program,
and that it is installed correctly. If you have a hard disk and
the program is stored in a directory on that drive, make
sure you are logged onto or specifying the correct directory.
If you don’t have a hard disk, make sure you inserted the
correct diskette in drive A.
2. Your computer can run at high or low speed. While almost all
programs work properly at the faster speed, some must run
at the slower speed. Check your software manual to see if
this is the case, and change the processor speed if necessary.
See “Changing the Processor Speed” in Chapter 1 for
instructions and information on using copy-protected
programs.
3. If you entered an MS-DOS command that you want to stop,
there are special key combinations you can use to cancel the
command. These methods may also work in your
application programs:
0
Hold down CT_] and press Ic]
Q Hold down [m] and press [Bleak].
4. An application program can occasionally lock the computer,
making it unresponsive to keyboard commands. If your
computer does not respond when you type on the
keyboard, you can reset it. Follow the instructions in
Chapter 1.
Troubleshooting
6-22
5. If resetting the computer does not help, remove any
diskettes, turn off your system, wait 20 seconds, and turn it
back on. Then restart your application program.
If none of these solutions solve your software problem, contact
the software manufacturer for technical support.
Printer Problems
Below are some general steps to follow if you have difficulty
with your printer. If the problem persists and you need more
detailed information, check your printer manual.
You see a port error message if you are having trouble with the
port to which your printer is connected.
1. If your printer does not work at all, check that the printer
has power and is properly connected to the computer.
(Also, make sure your printer has paper in it.) See
Chapter 1 of the Setup Guide or your printer manual for
instructions.
2. Check the printer manual for the printer’s correct DIP switch
or control panel settings. These settings help a printer
communicate properly with the computer.
3. If you are using more than one parallel port, the computer
must know which port is the primary port and which is the
secondary port. See Chapter 2 of the Setup Guide for
instructions on how to set the parallel and serial ports using
the SETUP program.
4. If your printer is properly set up but is still not functioning,
test it from the MS-DOS level. When the screen displays the
MS-DOS command prompt (such as C> or A>), hold down
fini and press screen . This should print the contents of
the screen on your printer.
6-22 Troubleshooting
If it does not, you may need to change the internal setting
of the computer’s parallel port for a parallel printer (or
serial port for a serial printer). To do this, use the MS-DOS
MODE or SETMODE command. See your printer manual
and MS-DOS documentation for more details.
5. Many application programs (such as word processors)
must be set up properly before they can use a printer.
Check your program manual to see what customizing may
be required.
6. If you are using an application program that requires a
printer driver, make sure the correct driver is installed. See
your application program manual for instructions. Also see
your printer manual for additional instructions on using
your printer with application programs.
7. Try running the Parallel port diagnostic test if you have a
parallel printer, or the Serial port test if you have a serial
printer. You can also test a dot-matrix printer, if you have
one. Chapter 4 describes these tests.
Option Card Problems
If you install an option card and it does not function properly,
check the following:
1. Is the option card installed correctly? Make sure it is
well-seated in its slot. Check the installation procedure
described in Chapter 2 and also see the instructions that
came with the card.
2. Did you set the necessary DIP switches or jumpers on the
option card? See the card’s manual for instructions.
3. Did you set the necessary jumpers on the main system
board? See Chapter 2 for more information.
Troubleshooting
6-23
4. Did you run the SETUP program to update your computer’s
configuration after installing the card? See Chapter 2 of the
Setup Guide.
5. If you used the option card to add an external device to
your computer, did you use the proper cable to connect the
device to the card?
6. Did you perform the correct setup procedures for the
software you are using with the option card? See your
option card or software manual for instructions.
Mouse Problems
If you have trouble with your mouse or you see an auxiliary

Memory Module Problems
If you added extra memory to your system by installing SIMMs
and that memory is not operating properly, check the following:
1. If the memory count displayed by the power-on diagnostics
program is incorrect, you may not have installed the
SIMMs correctly. They may be the wrong type of SIMM or
they may not be inserted all the way.
See “Memory Modules (SIMMs)” in Chapter 2 and make sure
you followed all the instructions.
2.
Be sure to run the SETUP program after you install or
remove memory modules to automatically update your
memory configuration. See Chapter 2 of the Setup Guide for
instructions.
3.
If you still have trouble with your SIMMs, write down any
error messages that appear and contact your Authorized
