2 Introduction
Energy Savings
In standard configurations, this computer complies with the
United States Environmental Protection Agency’s Energy Star
Program, which promotes the manufacture of energy-efficient
printers, computers, and monitors. Your computer’s
“Green PC” feature places the hard disk drive in a low-power
standby mode when the mouse and keyboard have been
inactive for a specified period of time. It also stops sending
video signals to your monitor.
Note
If you have an Energy Star compliant monitor, it also goes
into a low-power standby mode because it isn’t receiving
video signals from your computer. (Screens on
non-compliant monitors go blank, but do not enter a
low-power standby mode.)
VGA Drivers
Your computer comes with VGA drivers and utilities for use
with the integrated video interface. With these drivers, you can
take advantage of the extended VGA features such as higher
resolutions and 132-column text mode when you run popular
applications. If your system was configured for you, these
drivers and utilities may be installed on your hard disk. If you
need to install them yourself, see the instructions in Chapter 1.
To obtain drivers for additional applications, call the EPSON
ConnectionSM or access the Epson America Forum on
CompuServe®.
Introduction 3
Optional Equipment
You can easily upgrade your computer by installing additional
memory and a wide variety of options, as described in
Chapters 3 and 4.
MemoryBy adding 1MB, 2MB, 4MB, 8MB, 16MB, or
32MB SIMMs (single inline memory
modules) to the main system board, you
can expand the computer’s memory up to
64MB.
Video
Memory
CPU
Cache
Drives
You can increase the video memory in
your system to 1MB, which allows you to
use higher resolutions with more colors.
Your system supports a variety of
microprocessors, including 5 Volt, 3.3 Volt,
3.45 Volt, and 3.6 Volt processors; see
Chapter 3 for more information.
You can increase the external cache
memory size to 64KB, 128KB, or 256KB by
installing cache SRAM chips on the main
system board, allowing you to access data
faster and improve overall system
performance.
Your system supports up to four mass
storage devices, including hard disk
drives, diskette drives, a tape drive, a
CD-ROM drive, or an optical drive.

Setting Up Your System
1-1
If you purchased any optional equipment that goes inside the
computer-such as option cards, memory modules, or
drives-you should install these devices before you connect
your computer. See Chapters 3 and 4 for instructions.
Setting the Voltage Selector Switch
Your system is powered by a 200 Watt power supply. The
power supply voltage is controlled by a voltage selector switch
on the computer’s back panel. You can set this switch to
110 VAC or 220 VAC.
EPSON ships the computer with the voltage selector switch set
to 110 VAC. This setting is appropriate for line source voltages
between 100 and 120 VAC, and is generally the appropriate
setting to select if you plan to use your computer in North
America, South America, or Japan.
If you plan to operate the computer in the United Kingdom,
Europe, or some South American countries, you will probably
need to reset the voltage selector switch to 220 VAC. Doing so
allows your computer to handle line source voltages between
200 and 240 VAC, which are standard in Europe.
1-2Setting Up your System
Caution
Before you turn on the power to your system, make sure the
voltage selector is set to the appropriate setting for the
electrical power source in your location or you will seriously
damage your system.
To change the voltage selector switch setting, slide the switch
to the right to select 220 VAC or to the left to select 110 VAC.

1-6
Running the SETUP Program
Be sure to run SETUP the first time you use your computer, so
you can verify or update the configuration information. You
also may need to run SETUP again later if you change your
configuration.
SETUP lets you verify or change the following:
0
System settings such as date, time, diskette drive type(s),
and video display type
0
Automatic or manual selection of hard disk drive(s)
0
Automatic or manual selection of advanced hardware
features for optimizing system performance
0
System booting options
0
Password security and anti-virus features
0
Green PC options, such as the time intervals before the
system and the hard disk drive go into low-power standby
mode.
SETUP also allows you to see summary information about your
system.
The SETUP program and the factory default settings are stored
in the computer’s ROM BIOS (read-only memory, basic
input/ output system). The configuration information you enter
is stored in an area of memory called CMOS RAM. This
memory is backed up by a battery, so it is not erased when you
turn off or reset the computer.
Setting Up your System1-7
Starting the SETUP Program
When you start your computer, it performs some power-on
diagnostics. During these diagnostics, you may see the
following message:
Press <F2> to enter SETUP
(In SETUP, you can disable this message, if desired.)
Press F2 to run SETUP. This message is only on the screen for a
few seconds. If you missed it, restart the computer and try
again.
If the system detects an error in your configuration, you hear
two beeps and see an error message followed by this message:
Press <F1> to resume, <F2> to Setup
Press F2 to run SETUP.
SETUP displays the Main Menu. From this menu, you can
select the various options to identify your system’s
configuration and then save your new values to CMOS. If you
change your mind, you can cancel any changes you have made
and restore the default values stored in ROM or load the values
previously stored in CMOS.

The System Setup Option
From the System Setup screen, you can set the options
described below.
Setting the time and date
The real-time clock in your computer continuously tracks the
date and time-even when the computer is turned off. Once
you set the System Time and System Date options, you
should not need to change them, unless you adjust the time for
daylight savings or a different time zone. (The computer
automatically changes the date for leap years.)
Setting the video display type
The Video Systemoption allows you to define the type of
display adapter you are using. If you connected your monitor
to the computer’s built-in VGA port, select EGA/VGA.
Setting Up your System
1-9
If you connected a monitor that doesn’t support VGA to a
video adapter card installed in your system, select either the
CGA 80 X 25 or the Monochrome option. Also make sure
you disabled the on board VGA controller by setting jumpers
J14 and J15 to the Off position. (See Chapter 3 for instructions.)
Checking system memory
When you boot your system, the system BIOS detects the total
memory size automatically. You see the memory configuration
displayed in the System Memory and Extended Memory
fields on this SETUP screen.
You cannot change these values; if they are not what you
expect them to be, check that the SIMM(s) are securely seated
in their sockets. (See Chapter 3 to locate the SIMM sockets.)
Setting the diskette drive type(s)
On your system, diskette drive A is the 3.5-inch high-density
drive installed in your computer. You may also have another
drive of a different size or capacity; this is drive B. Check the
settings for both drives and correct them if necessary.
The Fixed Disk Setup Option
The options on the Fixed Disk Setup screen define the types of
hard disk drives you installed in your system. From this screen,
select Fixed Disk 0 Control or Fixed Disk 1
Control.
Your computer comes with a hard disk auto-sensing feature.
Press Enter when the Autotype Fixed Disk option is
highlighted. The system detects the type of hard disk drive and
fills in the remaining fields on the screen.
1-10Setting Up your System
If you are using an older drive or a preformatted drive, it may
not support the auto-sensing feature. If you press Enter when
the Autotype Fixed Disk option is highlighted and the
drive parameters do not match your drive, check Appendix A
to see if your drive’s parameters are included in the hard disk
drive table. If not, you need to define your own drive type or
reformat the disk. See the next section for instructions on how
to define your own drive type.
Defining your own drive type
If the parameters for your hard disk do not match the
parameters detected by the auto-sensing feature, or if you want
to use your drive with parameters other than the defaults, you
can define your own type. To define your own drive type,
follow these steps:
1.
Move the cursor to Type and select User.
2.
Type the values in each field that are appropriate for your
hard disk drive.
3.
When you exit SETUP, make sure you save your changes.
The Advanced System Setup Option
When you select this option from the Main Menu, you see the
Advanced System Setup screen, which contains the options
described below.
Your system can automatically configure the Advanced
System Setup options for you. To avoid configuration
problems, you should let the system configure these options.
However, if you connected a scanner or a parallel port network
adapter to your parallel port, be sure to select Advanced
Chipset Control so you can change the operation of the
parallel port to PS2 mode (for bidirectional operation). See
page 1-13 for more information.
Setting Up your System1-11
Configuring cache memory
The system can configure your Memory Cache options or you
can manually set them. If you installed external cache, enabling
cache memory improves system performance, especially in
large data retrieval and processing environments.
If you choose to configure the cache memory yourself (rather
than let the system configure it for you), you can define the
write and burst wait states and two non-cacheable areas of
memory. However, it’s a good idea to let the system
automatically configure these features.
Configuring memory shadow
The system can configure the Memory Shadow options or you
can manually set them. You can enable or disable shadowing of
your system and video memory and control the specific blocks
of ROM used for this purpose.
Your computer can access RAM faster than ROM. The options
on this screen allow your system to copy the contents of its
system and/ or video ROM into RAM. When you use
shadowing, your system can perform certain operations faster,
providing a significant increase in performance.
Note
For the best system performance, always set the System
shadow and the Video shadow options to Enabled.
If you enable shadowing for specific blocks, the ROM located in
these blocks is copied to the shadow area.
1-12
Setting Up your System
Configuring chipset registers
The system can set your Advanced Chipset Control
options or you can manually change the values in the chipset
registers. Setting these values correctly increases your system
performance; however, setting them incorrectly may cause
your system to malfunction or shut down. Be sure to set the
Auto Configuration option to Enabled to let the system
automatically configure these options to avoid problems.
However, if you connected a scanner or a parallel port network
adapter to your parallel port, you should set Auto
Configuration to Disabled so you can change the
Printer Port Control option to PS2 mode (for
bidirectional operation). The default setting for the parallel port
is AT mode (for unidirectional operation).
Setting the Boot Options
When you select Boot Options from the Main Menu, you see
the Boot Options screen, which contains the options described
below.
Selecting the drive boot sequence
The Disk drive boot sequence option determines the
order in which the computer checks the drives when it looks
for the operating system.
If you select A: then C:, each time you turn on the
computer, it first tries to load the operating system from drive
A. If drive A doesn’t contain an operating system, the
computer loads it from drive C. If you select C :
computer tries to load the operating system from drive C first.
If drive C doesn’t contain an operating system, the computer
tries to load it from drive A. If you select C:
computer tries to load the operating system from drive C only.
Setting Up your System
then A:, the

1-13
Setting the floppy seek option
If you set the Disk drive boot sequence option to
C: only, you can disable the Floppy seek option so the
system does not try to access the diskette drive at startup.
Disabling the Floppy seek option decreases the time needed
to boot the system.
Disabling the SETUP prompt
The Display SETUP prompt during POST option allows
you to disable the message Press <F2> to enter SETUP
that you see during power-on diagnostics. You may want to
disable this prompt to prevent unauthorized users from seeing
the SETUP prompt. Even when the message is disabled,
however, you can still start SETUP by pressing F2 within the
allowed amount of time.
Disabling power-on diagnostic error messages
The Pause on POST errors option allows you to disable
the error message and the message Press <F1> to
resume, <F2> to Setup that you see when the system
identifies a configuration error. If you disable this option, the
system ignores configuration errors it finds during power-on
diagnostics and starts as it normally would. It’s a good idea to
keep this option enabled.
Disabling the system summary screen
By disabling the System summary screen at boot
option, you can disable the system summary screen that you
see when you start the system. If you disable this option, your
system starts up faster. You can see the same screen by
selecting the System Summary option from the Main Menu.

The System Security and Anti-Virus Options
When you select the Security and Anti-Virus option
from the Main Menu, you see the System Security and
Anti-Virus screen, which contains the options described below.
Entering or changing a password
You can define both User and Supervisor password levels for
this system. If the system will be used by more than one
person, you may want to set a Supervisor password for
yourself and a User password for others you don’t want to
have complete access to the system. For instance, you may
want to restrict access to the diskette drives or the computer’s
virus protection features.
If you enable the Password on boot option, you must enter
the Supervisor or User password each time you turn on the
system. If you do not enable this option but you have defined
passwords, you must enter the password each time you start
the SETUP program. If both a Supervisor and User password
are enabled, SETUP displays options for setting the User
password only for users who logged on with a user password.
To specify a User password, you must first specify a Supervisor
password. Follow these steps to enter or change a Supervisor
password:
1.
Select the Set Supervisor Password option and press
Enter.
2.
You see a Set Supervisor Password window. Type the
password you want to use, then press Enter. You can define
a password of up to eight characters.
3.
Type the same password a second time and press Enter.
You see a message that your changes have been saved.
Setting Up your System1-15
4. Press the spacebar. The Supervisor Password IS option
is now set to Enabled.
To set a User password, select the Set User Password
option and follow the steps above.
Deleting passwords
To delete your passwords, follow these steps:
1.
Set the Password on boot option to Disabled.
2.
Delete the User password by pressing Enter for both the
password field and the confirmation field. Don’t type any
characters in these fields.
3.
Then delete the Supervisor password the same way.
Note
You must delete the User password before SETUP will allow
you to access the Supervisor password.
If you have forgotten your password(s), see “Password
Problems” in Chapter 5.
Using the virus protection features
Several options on the Security and Anti-Virus screen allow
you to define system protection features.
The Diskette Access option allows you to restrict access
to your diskette drives based on the password levels you have
defined. This prevents unauthorized users from accessing the
drives and possibly introducing a virus to your system. You
can restrict diskette access only if passwords are enabled and
you have enabled the Password on boot option.
1-16
Setting Up your System
If you select Supervisor for this option, you can access the
diskette drives only if you enter the Supervisor password when
you start your system. Someone who starts the system with a
she tries to access the diskette drive. If you select User for
the Diskette Access option, you can access the diskette
Note
To use passwords for diskette drive access, you must enable
the Password on boot option. If you select a password
level for Diskette Access but leave the Password on
boot option disabled, you see an error message whenever
you try to access your diskette drive.
You can also protect your system by selecting Write
protect for the Fixed disk boot sector option.
When this option is enabled, the system displays an error
message when a program tries to write to the boot sector of
your hard disk drive. To use a legitimate program (such as the
MS-DOS@ FORMAT command) you must disable the write
protect option.
Two additional options on this screen allow you to define time
intervals for the system to display a prompt asking whether
you have performed your scheduled virus check or your
scheduled backup for your hard disk drive. You can disable
these prompts or have them display Daily, Weekly, or
Monthly. If you respond that you have not performed these
functions, however, the system still starts normally.

Using the Green PC Features
The Green PC options allow you to define how the
energy-saving features of this Energy Star compliant system
will work for you. The options on the Green PC Features screen
allow you to disable the energy-saving feature or set time-out
periods to put the system and hard disk drive in a low-energy
standby mode.
The Inactivity Timer 1 option sets the time-out period
for video signals to your monitor. When the mouse or
keyboard has been inactive for the time period you select here,
your computer stops sending video signals to your monitor. If
your monitor is also Energy Star compliant, it goes into a
low-power standby mode because it isn’t receiving video
signals from your computer. Screens on monitors that aren’t
Energy Star compliant will go blank when your system is in
standby mode.
If you select a time period for the Lockout Timer as well as
the Inactivity Timer 1 option, the system won’t accept
your keyboard input for the specified period of time after your
system has returned to an active mode. This allows time for
your monitor to return to full power also.
The Fixed Disk Timeout option determines the time-out
period for your hard disk drive. The hard disk drive goes into a
low-power standby mode when the mouse and keyboard have
been inactive for the period of time you’ve indicated.
Note
Some hard disk drives do not support a low-power standby
mode. Also, the delay caused by the hard disk drive
returning to active mode may cause errors in some
applications. If you have problems, you may want to disable
the Fixed Disk Timeout option.

environment.
0
Use good posture. Keep your elbows, hips, and knees bent
at approximately 90 degree angles and keep your wrists as
close to horizontal as possible.
0
Vary your posture often and take frequent breaks. Stand
up, stretch, and move around.
0
Use a good chair. Make sure your chair supports your
lower back. A chair with padded armrests lets you rest
your arms as you work.
Using your Computer
2-1
If you use a copy stand, keep it at the same eye level as
your screen. This reduces eye and neck strain. Also, rest
your eyes occasionally by closing them or focusing on a
fixed spot in the distance.
Be gentle with your keyboard. Too much force creates
tension in your hands. Also, make sure your work surface
has enough room for you to move the mouse or other
pointing device freely.
Use good lighting that isn’t too bright. Try to keep bright
light sources out of your field of vision when you are
looking at the screen.
Place your monitor directly in front of you and sit about an
arm’s length away from it. The top of the screen should be
slightly below your eye level so you look down at the
screen. Position the monitor so that no light is reflected
from the screen.
Stopping a Command or Program
You may sometimes need to stop a command or program while
it is running. If you have entered an MS-DOS or application
program command that you want to stop, try one of the
following:
0
Press Pause
0
Press Ctrl C
0
Press Ctrl Break.
If these methods do not work, you may need to reset the
computer as described below. Do not turn off the computer to
exit a program or stop a command unless you have to, because
the computer erases any data you did not save.
2-2Using Your Computer
Resetting the Computer
Occasionally, you may want to clear the computer’s 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 normally. If
you reset the computer without properly exiting a program,
you may lose data.
Also do not remove a diskette or reset or turn off the
computer while a diskette drive light is on. You could lose
data. Be sure to remove all diskettes before you turn off the
computer.
To reset the computer, press Ctrl Alt Del. The screen displays
nothing for a moment and then the computer reloads your
operating system.
You can also press the RESET button located in the upper right
corner on the front of your computer.
If resetting the computer does not correct the problem, you
probably need to turn it off and on again. 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.
Using your Computer2-3
Using Energy Wisely
By purchasing this low-power, Energy Star compliant
computer, you join a growing number of users concerned about
conserving energy. Here are a few additional tips you can use
to be even more energy-wise:
0
If your printer and monitor aren’t Energy Star compliant,
turn them off when you’re not using them.
0
Use your software’s print preview option (if available)
before you print something. You’ll be able to catch
formatting errors before you commit them to paper.
0
If you have an electronic mail system available to you, send
E-mail rather than memos. Not only is this faster, but you’ll
save paper and storage space too.
0
Use recycled paper whenever you can
Using Your Green PC Features
Your computer places the system, the hard disk drive, or both
into a low-power standby mode when the keyboard or mouse
has been inactive for the time periods you select in SETUP. See
Chapter 1 for information on setting these values.
When your system is in standby mode, the Num Lock light on
your keyboard flashes and your screen is blank. Press any key
or move the mouse to resume activity.
If the hard disk drive is in standby mode, it doesn’t return to
active mode until you access it. You’ll hear it start again. It will
take a second or two to reach its operating speed and read or
write to the disk. The hard disk drive access light turns on
when the system begins accessing the disk.
2-4Using Your Computer
Note
Some hard disk drives do not support a low-power standby
mode. Also, the delay caused by the hard disk drive
returning to active mode may cause errors in some
applications. If you have problems, you may want to disable
the standby mode for the hard disk drive.
Changing the Processor Speed
Your computer’s processor can operate at two speeds: fast or
slow (8 MHz). The slow speed is available to provide
compatibility with older application programs, such as those
that require you to leave a key disk-the diskette that contains
the copy protection-in the diskette drive.
When your computer is operating at fast speed, the SPEED light
on the front panel is on. When the computer is operating at
slow speed, the light is off.
You should use fast speed for almost everything you do
because your programs will work faster. However, certain
application programs have specific timing requirements and
can run only at the slower speed. See your application software
manual to determine if this is the case.
You can change the processor speed temporarily by entering
one of the following commands from the numeric keypad on
your keyboard :
0
To select slow speed, press Ctrl Alt --. (Press the --key on the
numeric keypad.)
0
To select fast speed, press Ctrl Alt +.
The speed setting remains in effect until you reset your
computer or turn it off.
Using your Computer2-5
Note
You can use the commands listed above while you are
running a program. However, if the program uses one of
these commands for another function, you cannot use it to
change the processor speed.

As you install option cards, keep these guidelines in mind:
0
Check the components on your card and the system board
before deciding which slot to use. Make sure that no
components are touching or obstructing other cards or
cables.
0
When you unpack the option card, do not touch any of the
components on the circuit board or the gold-edged
connectors. 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.
0
Before you install the card, adjust any switches or jumpers
on it, if necessary. (See the instructions that came with the
card.) Also, see if you need to change any jumper settings
on the system board. (For example, if you install a video
card, you need to disable the built-in VGA adapter.) See
page 3-6 for more information on jumpers.

Adding Video Memory
Your computer comes with 512KB or 1MB of video memory. If
you have 512KB, you can increase your video memory to 1MB
by installing four video DRAM DIP (Dual Inline Package)
chips. The chips must be 20-pin, 256KB chips that operate at a
70ns access speed. For the memory to work properly, you must
install one chip in each empty video RAM socket on the system
board.
Additional video memory is useful for running graphicsintensive applications or for supporting video resolutions up to
1280 x 1024 in 16 colors. See Appendix A for information on
supported colors and resolutions for each amount of video
memory.
The table below lists the video DRAM DIP chips that are

Troubleshooting
Keyboard Problems
The screen displaysa keyboard error message when you
turn on or reset the computer.
Make sure the keyboard is securely connected to the keyboard
port and not the mouse port. Although these ports look alike,
they cannot be used interchangeably.
Nothing happens when you type on the keyboard.
The Lockout Timer may be set in SETUP. This option
inactivates the keyboard for a specified period of time after the
system returns to an active mode from a low-power standby
mode. This delay gives Energy Star compliant monitors the
time they need to return to an active mode. Wait a few seconds
and try again.
See “The Computer Does Not Respond,” above
The cursor keys on the numeric keypad do not work
properly.
If the Num Lock light in the upper right corner of the keyboard
is lit, press NumLock to turn off the function.
Mouse Problems
Yourmouse isn’t working properly or you see an auxiliary
device error message.
Make sure the mouse cable is securely connected to the MOUSE
port and not the keyboard (K/B) port. Also make sure you
installed the mouse driver correctly (if necessary). See the
documentation that came with your mouse for instructions.
(Windows automatically installs a mouse driver when you
install the program.)

Monitor Problems
There is no display on the screen.
Check that the monitor’s power switch is on and that its power
light is on.
Also, the computer may be in low-power standby mode. When
you press a mouse button or a key on the keyboard, see if the
monitor displays an image.
The power light is on, but you still do not see anything on
the screen.
Press a mouse button or a key on the keyboard to see if the
computer is in low-power standby mode. Also, check the
brightness and contrast controls.
If you still do not see anything on the screen, make sure the
monitor is securely connected to the computer.
If you installed a display adapter card, make sure your monitor
type matches the card type. Also be sure you set the correct
display type in SETUP (see Chapter 1) and that the main
system board jumpers are set correctly (see Chapter 3).
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.
The powerswitch is on but the powerlight is not on.
If the monitor is Energy Star compliant, it may be in low-power
standby mode. Press a mouse button or a key on the keyboard
to activate the monitor.
Turn off the monitor’s power, wait five seconds, and turn it
back on.
5-6
Troubleshooting
If the 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. If the light
turns on, your monitor may be faulty.
Diskette Problems
You see a diskette error message.
Reinsert the diskette, making sure you insert it all the way. If
the drive has a latch, turn it down to secure the diskette.
Also, check to see that you have inserted the right type of
diskette in the drive. For example, make sure you are not
inserting a high-density diskette in a double-density drive.
If reinserting the diskette does not solve the problem, insert the
diskette in another diskette drive of the same type. If you can
read the diskette in a different drive, your drive may be faulty.
The diskette is the tight type, but you still see an error.
Check that the diskette is not write-protected, preventing the
drive from writing to the diskette.
Make sure the diskette is formatted. See your operating system
documentation for instructions on formatting diskettes.
The system may have the Diskette Access option in
SETUP enabled. If you entered a User level password when
you started the system but this option is set to a Supervisor
level, you see an error when you access the drive.
You may have a defective diskette. Try copying the files from
the bad diskette to a new diskette.

Something is wrong with the data in the files
If you are using MS-DOS, run CHKDSK to repair the files. You
may also be able to use special utilities or diagnostics to solve
this problem.
Diskette Drive Problems
A newly installed diskette drive is not working properly.
Make sure you have installed the drive correctly and check all
the cable connections.
You see a diskette drive error when you start your computer.
Run the SETUP program and configure your system for the
correct type of diskette drive.
The diskette drive is making loud or unusual noises
Contact your Authorized EPSON Servicer or the EPSON
Connection.
Hard Disk Drive Problems
A newly installed hard disk drive is not working properly or
its performance is not what you expect.
Make sure you have installed the drive correctly and check all
cable connections. Also, check the jumper settings on your
drive.
Some hard disk drives do not support the Energy Star features
on your system. You may need to disable these features in
SETUP.
5-8
Troubleshooting
You see a hard disk drive error when you start your system.
Run SETUP and check that your system is auto-sensing the
correct drive type. If auto-sensing is enabled and SETUP
displays information that does not match your drive, you may
need to define your own drive type. See Chapter 1.
Make sure the jumpers on the system board are set correctly.
Jumpers JB and JE enable or disable the IDE hard disk drive
controller. See Chapter 3 for jumper information.
Make sure the jumpers on the hard disk drive are set correctly.
See the documentation that came with the drive for more
information.
You ate unable to store data on the hard disk drive.
If the hard disk drive has been in low-power standby mode,
make sure the drive has had time to achieve its full operating
speed before you try to write data to it.
If your drive was not configured, make sure you have
partitioned and formatted it correctly for your operating
system. See your operating system manual for instructions.
Also, make sure your hard disk drive has been physically
formatted by the manufacturer. (All EPSON-supplied drives
are physically formatted at the factory.) If it has not been
physically formatted, use the format utility that came with the
drive to format it before you partition it or install the operating
system. (Note that a physical format is different from
software-based formatting commands, such as the MS-DOS
FORMAT command.)
Troubleshooting
5-9
You have been using your hard disk drive successfully for
some time but notice a reduction in performance.
The data on the disk may have become fragmented. Back up all
your data and use a disk compaction utility to reorganize the
files on your disk.
If you cannot access data on your hard disk or you are seeing
read/ write errors, the disk may have a physical problem.
Contact your Authorized EPSON Servicer or the EPSON
Connection.
Password Problems
You have forgotten your password.
You must discharge your CMOS memory. To do this, you
need to change the setting of jumper J30 to position 3-4. See
Chapter 3 for details on changing the jumper setting.
After you have changed J30, restart your system, leave it on for
a few seconds, then turn it off again. This resets the SETUP
values to their factory defaults. Both the Supervisor and the
User passwords are disabled.
Set J30 back to position 2-3. Then turn the computer on again.
Use SETUP to set a new password, if you want one.

Troubleshooting
Software Problems
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 do not have
a hard disk, make sure the correct diskette is in the diskette
drive. If you need help, contact your software manufacturer.
The application program is having trouble reading a key
disk.
You may be running an application that requires a slower
processor speed. Change your processor speed using the
keyboard commands described in Chapter 2.
The application program is having trouble reading from or
writing to the hard disk drive.
If you have enabled the Fixed Disk Timeout option in
SETUP, your application may be timing out during the few
second delay when the hard disk drive returns to its operating
speed after being in standby mode. Disable this option in
SETUP (see Chapter 1).
Yourapplication haslocked the computer, making it
unresponsive to keyboard commands
Reset the computer and try again. If resetting the computer
does not help, turn it off, wait 20 seconds, then turn it on again.
Some software, like OS/ 2®, UNIX®, or NetWare®, needs a
minimum of 8MB to 16MB of RAM to work correctly. Check
your software documentation for the minimum memory
requirements. If necessary, add additional memory using the
instructions in Chapter 3.
