Read This First
Before you set up your EPSON® EL 486UC+ computer, read
this card for guidelines on how to get started. Also keep it
around for future reference because it provides important
information about your system and how to get technical
assistance when you need it.
Setting Up Your System
Most systems sold by EPSON Direct” are preconfigured; all the
hardware and software (such as MS-DOS® and Microsoft®
Windows™, is already installed. However, be sure to follow
these general procedures when setting up your system:
1.
Install any internal options. If you purchased additional,
optional equipment that goes inside the computer—such as
option cards, memory modules, a hard disk, or a diskette
drive-you should install these devices first. See Chapters 4
and 5 in your User's Guide for instructions.
2.
Set up the computer. Follow the steps in Chapter 1 of the
User's Guide to connect your system components and in
Chapter 2 to run the SETUP program.
3.
Install your Windows applications and other software.
Install any Windows applications and other software
programs you plan to use. See the documentation that
came with the application programs for instructions.
Note
Be sure to make backup copies of all the diskettes you
use to set up your system and install your software.
1
4.
Install VGA device drivers and utilities. If you have a
monitor that supports resolutions over 640 x 480, you’ll
probably want to use some of the VGA device drivers and
utilities that came with your computer to enhance the
display capabilities of your built-in VGA adapter. Drivers
for Windows have been installed on the hard disk. To
install additional drivers, see the README file on the
Utility diskette for instructions.

Introduction 1
Using the built-in interfaces, you can connect most of your
peripheral devices directly to the computer, so you do not have
to install option cards. You can use the option slots to enhance
your system with extra functions such as a modem card, a
network controller card, or additional interface ports.
The shadow RAM feature speeds up processing by moving the
system and video BIOS into the RAM area of memory.
With the standard 512KB of video RAM, the VGA controller
supports standard resolutions up to 640 x 480 in 16 colors and
extended resolutions up to 640 x 480 in 256 colors or 1024 x 768
in 16 colors (interlaced or non-interlaced). When you upgrade
to 1MB of video RAM, the system supports extended
resolutions up to 1024 x 768 in 256 colors.
Your system may have been configured for you. If so,
everything you need to get started is already in place. Your
hardware configuration options have been set to ensure
optimal system performance. The hard disk drive already
contains the MS-DOS ® operating system and Microsoft@
Windows. TM In addition, the drivers needed to take advantage
of your system’s enhanced video resolutions have been
installed for you. Just connect your keyboard, mouse, and
monitor and you’re ready to go.
VGA Drivers
Your computer comes with VGA drivers for use with the
integrated VGA interface. With these drivers, you can take
advantage of the extended VGA features such as high
resolutions and 132-column text mode when you run popular
application programs. If your system was configured for you,
these drivers are already installed. If you need to install them
yourself, a README file on your Utility diskette describes how
to install the VGA drivers for common application programs.
2 Introduction
OptionaI 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 4 and 5.)
System Memory
By adding 4MB, SMB, 16MB, and 32MB SIMMs (single inline
memory modules) to the main system board, you can expand
the computer’s memory up to 64MB.
Cache Memory
You can increase your cache memory to 64KB, 128KB, or 256KB
by installing SRAM chips on the main system board.
Additional cache allows your system to access frequently used
data faster, improving overall system performance.
Video Memory
You can install video memory chips to increase the video
memory to lMB, allowing you to use higher resolutions with
more colors.
Microprocessor
You can upgrade your system with these microprocessors:
486SXJ 33
486DW 33
486DX2150
486DX2166.
Introduction 3
Math Coprocessor
You automatically install a math coprocessor when you
upgrade your system with a DX or DX2 microprocessor,
because a math coprocessor is built into the 486DX and 486DX2
chips.
Drives
Your system can support up to four mass storage devices,
including hard disk drives, diskette drives, a tape drive, a
CD-ROM drive, or an optical drive. As your storage needs
expand, you can install additional drives. Some restrictions
apply however; see Appendix A for more information.
How to Use This Manual
This manual contains the information you need to get the best
results from your computer. You don’t have to read everything
in this book; see the following chapter summaries to find the
sections you need.
Chapter 1 provides simple instructions for setting up your
system and connecting peripheral devices such as the monitor
and printer.
Chapter 2 describes how to run the SETUP program to define
your computer’s configuration. You may need to do this the
first time you use your computer, or later if you change the
configuration.
Chapter 3 covers general operating procedures, such as
resetting the computer, using the password, and changing the
processor speed.
4 Introduction
Chapter 4 describes how to remove and replace the computer’s
cover, change jumper settings, and install optional equipment
such as microprocessor upgrades, option cards, and memory
modules.
Chapter 5 explains how to install and remove disk drives.

Turning the computer on and off.
Getting Started
Follow the instructions below for choosing a location for your
new system and unpacking it.
Choosing a Location
When you are ready to set up your system, choose a safe,
convenient location that provides the following:
A flat, hard surface. Surfaces like beds and carpets attract
static electricity, which can erase data on your disks,
damage the computer’s circuitry, and prevent proper
ventilation.
Moderate environmental conditions. Select a cool, dry area
and protect your computer from extremes in temperature,
humidity, dust, and smoke. Avoid direct sunlight or other
sources of heat.
Good air circulation. Leave several inches of space around
the computer so air can move freely.

No electromagnetic interference. Do not place your system
too close to any electrical device, such as a telephone or
television, which generates an electromagnetic field.
0
Appropriate power source. Connect all your equipment
with the appropriate power cords for the power source in
your area.
Unpacking Your Computer
When you unpack your system components, make sure you
have these items:
computer
diskette
keyboard
manual
Your system may also include an EPSON PS/2 compatible
mouse and may come with the operating system and software
already installed on a hard disk drive.
If you purchased any optional equipment that wasn’t installed
at the factory—such as option cards, memory modules, a hard
disk, or a diskette drive-you install these options before you
connect your computer. See Chapters 4 and 5 for instructions.

Caution
Although the connectors and ports for the mouse and
keyboard are physically identical, they cannot be used
interchangeably. Be sure to plug the mouse connector into
the MOUSEport, or you may damage your system.
If your system has not already been configured, you may need
to install a mouse driver. See your mouse manual for
instructions. (If you are using Windows, the mouse drive was
automatically installed by the program.)
Connecting a Monitor
You can connect your VGA monitor to the computer’s built-in
VGA port as described below. (If you will be using a different
type of monitor, connect it to the video adapter card installed
in your system instead.)
1.
Place your monitor on top of or near the computer. Turn the
monitor and computer around so the backs are facing you.
2.
There should be two cables provided with your monitor: the
monitor cable (to connect it to the computer) and the power
cable (to connect it to the power source). On most monitors,
the monitor cable is permanently attached to the monitor. If
your monitor does not have an attached cable, connect the
cable to it now.
3.
Examine the connector on the monitor cable and line it up
with the Sport on the computer. Then insert the
connector into the port.
Caution
To avoid damaging the connector, be careful not to bend
the pins when you insert it.

If necessary, use the controls on your monitor to adjust the
brightness and contrast until you can easily see the
characters on the screen. If your monitor has horizontal and
vertical hold controls, you may need to use them to
stabilize the display.
Setting Up Your System
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: \>.
If there is no operating system installed on your computer,
you see an error message. Ignore the message for now; once
you install the operating system, you will not see it.
Now you need to run the SETUP program to make sure your
computer is configured properly. First turn off the computer, as
described below, then see Chapter 2 for instructions. When you
finish running SETUP, be sure to see “Post-SETUP Procedures”
on page 2-13 for guidelines on what you need to do next.
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.
5.
Turn off the monitor, printer, and any other peripheral

Chapter 2
Running the SETUP Program
You may need to run the SETUP program the first time you use
your computer. If your system came unconfigured, you need to
define how it is set up. If your system was configured for you,
you may want to check the settings or adjust the date and time.
You also may need to run the program 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.
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.
Running the SETUP Program
2-1
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 <Fl> 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 table below lists the keys you can use to perform SETUP
operations.

The System Setup Option
When you select this option, you see the System Setup screen.
From this screen, you can set the system time and date, define
your video display type, check system memory, and define the
diskette drives.
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.)
Running the SETUP Program
2-3
Setting the Video Display Type
The Video System option allows you to define the type of
display you are using. If you have a VGA monitor that you
connected to the computer’s built-in VGA port, select EGA/VGA.
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. If you installed a
video adapter card, make sure you disabled the onboard VGA
controller by setting jumper 518 to the Off position. (See
Chapter 4 for instructions.)
Checking System Memory
Your computer comes with 4MB of RAM on a SIMM. MS-DOS
and application programs that run under MS-DOS use the first
640KB of memory. The memory above 1MB is extended
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 4 to locate the SIMM sockets.)
Setting the Diskette Drive(s)
On your system, diskette drive A is the 3.5-inch high-density
drive installed in the lower drive bay. 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.
2-4
Running the SETUP Program
The Fixed Disk Setup Option
The Fixed Disk Setup options define the types of hard disk
drives you installed in your system. When you select this
option, you see the Fixed Disk Setup screen. From this screen,
select F i x e d D i s k 0 C o n t r o l o r F i x e d D i s k 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.
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 Diskoption ishighlighted 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. (See Appendix A for a list of
predefined hard disk drive types and their parameters.)
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.
Running the SETUP Program
2-5
The Advanced System Setup Option
When you select this option from the Main Menu, you see the
Advanced System Setup screen. From this screen, you can
select options that allow you to configure the computer’s cache
memory and shadow memory, and define the advanced
chipset options.
Note
Your system can automatically configure the Advanced
System Setup options for you. To avoid configuration
problems, you should let the system configure these options.
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.
2-6
Running the SETUP Program
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.
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.
Running the SETUP Program
2-7
Setting the Boot Options
When you select Boot Options from the Main Menu, you see
the Boot Options screen. These options allow you to define the
boot sequence and determine the information you see on the
screen when you start up your system.
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 : then A:, the
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 : only, the
computer tries to load the operating system from drive C only.
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.
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.
2-8
Running the SETUP Program
The Pause on POST errors option allows you to disable
the error message and the message Press <Al> to
r e s u m e , <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.
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.
(See page 2-12.)
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. The password options on this screen let you
define both a Supervisor and a User password. You can specify
whether a password is required when you start the system.
The Diskette Access option allows you to restrict diskette
access at either the User or Supervisor password level to
protect your system from receiving a virus from a diskette.
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.
Running the SETUP Program
2-9
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.
4.
Press the spacebar. The Supervisor Password
is now set to Enabled.

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.
Running the SETUP Program
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 6.
Using the Diskette Access Option
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 into your system. You
can restrict access only if passwords are enabled and you have
enabled the Password on boot option.
If you select Supervisor for this option you can access the
diskette drives only if you enter the Supervisor password
during system startup. Someone who starts the system with a
User password, however, will see an error message when he or
she tries to access the diskette drive. If you select User for the
Diskette Access option, you can access the diskette drives
whether you enter the Supervisor or User password during
startup.
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.
Running the SETUP Program
2-11
The System Summary Option
When you select the System Summary option from the Main
Menu, the SETUP program displays a summary of the
configuration settings for your system.
This is the same screen you see during system startup. You can
choose not to have the system display this screen so system
startup is faster. See page 2-8 for information on disabling this
option.
Exiting SETUP
When you leave SETUP, you can save your settings, or exit
SETUP without saving your settings. You can also return all
values to the factory defaults.
To leave SETUP, press ESC from any SETUP screen. From the
Main Menu, you can do the following:
Load ROM

values to boot the system and
start over.
Press ESC to leave SETUP and restart your computer.
2-12
Running the SETUP Program
Post-SETUP Procedures
After you run SETUP for the first time, you may need to install
the operating system on your computer (if it is not already
installed). See your operating system manual for instructions.
Once you have installed your operating system, install any
software you plan to use. See your application program
manuals for instructions.
You may also want to install the optional extended video
drivers for some of your application programs. (If your
computer was configured for you, these drivers are already
installed.) See the README file included on your Utility
diskette for more information.
Note
If you plan to install video drivers for Windows
applications, you must install Windows before you install
the drivers.

This chapter briefly describes the following operations:
0 Working comfortably
0 Inserting and removing diskettes
0
Stopping a command or program
0 Resetting the computer
0 Using the password
0
Changing the processor speed.
Working Comfortably
Use the guidelines to create a comfortable work environment:
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.
Vary your posture often and take frequent breaks. Stand
up, stretch, and move around.
Use a good chair. Make sure your chair supports your
lower back. Padded armrests let you rest your arms as you
work.
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.
Using Your Computer
3-1
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.
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.
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.
Inserting and Removing Disks
To insert a diskette into a 3.5-inch drive, hold the diskette with
the label facing up and the metal shutter leading into the drive,
as shown in the following illustration. Slide the diskette into
the drive until it clicks into place.
metal shutter

Using Your Computer
To insert a diskette into a 5.25-inch drive, hold the diskette with
the label facing up and the read/ write slot leading into the
drive. When the diskette is completely in the drive, turn down
the latch to secure the diskette in the drive.
When you want to remove the diskette, make sure the drive
light is off; then press the release button or turn the latch.
Remove the diskette and store it properly.
Caution
Never remove a diskette, reset the computer, or turn it off
while a diskette drive light is on. You could lose data. Also,
remove all diskettes before you turn off the computer.
Sopping a Command or Program
You may sometimes need to stop a command or program while
it is running. If you have entered a 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.
Using Your Computer
3-3
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. If you reset
the computer without properly exiting a program, you may
lose data.
When you 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 operating system diskette in
drive A. If you are using DOS, you can hold down Ctrl and Alt
and press Del.
If you set the Disk drive boot sequence option in SETUP
to C: only (see Chapter 2), the operating system must be on
the hard disk when you reset the computer. If you selected A:
then C: or C: then A:, the operating system must be either
on the hard disk or on a diskette in drive A. If you do not have
a hard disk, insert a bootable diskette (one that contains the
necessary portions of the operating system) in drive A. If you
are using MS-DOS, press Ctrl Alt and Del to reset the system.
You can also press the RESETbutton located on the front panel
of your computer. The screen displays nothing for a moment
and then the computer reloads the operating system.
3-4
Using Your Computer
If resetting the computer does not solve the problem, you 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 drive, insert a bootable diskette in
drive A. Then turn on the computer.
Using a Password
In SETUP, you can define both a Supervisor level password
and a User level password. You can also specify whether a
password is required when you boot the system. This
password can also control access to the diskette drives.
If `you enabled the Password on boot option in SETUP, you
must enter the Supervisor or User password every time you
turn on or reset the computer. If you entered a password but
disabled the Password on boot option, you must enter the
password when you start SETUP.
If you set the Diskette Access option to Supervisor, you
can access a diskette drive only if you entered a Supervisor
password when you started the system. If you entered a User
password but the Diskette Access option is set to
Supervisor, you see an error message when you cannot
access the diskette drive.
When you enter your password, you’ll see the prompt, Enter
password:. As you type your password, you see a rectangle
for each character you type. When you press Enter, the
computer loads the operating system (or starts SETUP).
If you don’t enter the correct password the first time you type
it, you can try two more times. If you haven’t entered the
correct password on the third try, the computer locks up to
prevent unauthorized access. You see the message:
System Disabled!
Using Your Computer
3-5
You must turn off the computer and start over. You can reset
the computer using the RESETbutton but you cannot reset the
computer by pressing Ctrl Alt and Del.
Note
If you want to change or delete your password, you must

Changing the Processor Speed
Your computer’s processor can operate at two speeds: fast (the
speed of your microprocessor) or slow (8 MHz). The slow
speed is available to provide compatibility with older
application programs.
When your computer is operating at fast speed, the speed light
(labeled TURBO) 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 software manual to
determine if this is the case.
Some copy-protected programs require the computer to run at
slow speed while accessing the program on a diskette. These
programs also usually require you to leave a key disk-the
diskette that contains the copy protection-in the diskette
drive. If you use a copy-protected program, you can change the
speed to slow to access the diskette and return it to fast speed
when you are finished.
3-6
Using Your Computer
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 and then press the -key
on the numeric keypad. This turns off the speed light.
0
To select fast speed, press Ctrl Alt and press + on the
numeric keypad. The speed light comes on.
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.
The speed setting remains in effect until you one of do the
following:
0 Reset your computer
0
Turn off your computer
0
Change the speed with another keyboard command
0
Change the jumper setting of J25 (as described in
Chapter 4).

lnstalling an Option Card
This section explains how to install option cards in your
computer. Your computer has three 16-bit, full-length slots and
two S-bit, half-length slots to accommodate a total of five
option cards.
As you install option cards, keep these guidelines in mind:
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 S-bit cards in a 16-bit slot. When you
select the slot you want to use, make sure that no
components are touching or obstructing other cards or
cables.
If you have a DX or DX2 processor installed, you may not
be able to install a 16-bit card in the bottom slot because a
heat sink or heat sink/ fan assembly may be mounted on
the processor.
When you unpack the option card, be careful not to touch
any of the components on the circuit board or the
gold-edged connectors. If you need to set it down before
you install it, place it gently on top of its original packing
materials with the component side facing up. Keep the
packing materials in case you remove the card later.
Before you install the card, adjust any switches or jumpers
on it, if necessary. (See your option card documentation for
instructions.) Also, see if you need to change any jumper
settings on the system board. For example, if you install a
SCSI hard disk drive, you may need to change jumper 523
to disable the IDE hard disk drive controller. See page 4-6
for more information on jumpers.
