Federal Communications Commission (FCC) Statement
Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and receiver.
Ž
Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
Ž Consult the dealer or an experienced radio/TV technician for
help.
Any special accessories needed for compliance must be specified in the
instruction manual.
Warning: A shielded-type power cord is required in order to meet FCC
emission limits and also to prevent interference to nearby radio and
television reception. It is essential that only the attached power cord be
used.
Use only shielded cables to connect I/O devices to this computer.
You are cautioned that changes or modifications not expressly approved by
the party responsible for compliance could void your authority to operate
the equipment.
This digital apparatus does not exceed the Class B limits for radio noise
emissions from digital apparatus as set out in the radio interference regula-
tions of the Canadian Department of Communication.
Le Présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de Class B
preescrites dans le réglement sur le brouillage radioélectrique édicté parle
Ministère des Communications du Canada.
Warning
Reconfiguring
l
To keep the computer from being damaged, NEVER recon-
figure the board while the power is ON.
l
If you wish to reconfigure the computer at any time, ensure that
the power is turned OFF before changing any hardware settings, such as DIP switches or jumpers.

1-1 Introduction
This manual will guide you through the setup of your computer and
provide the information necessary to tailor the system to fit your needs.
If you are a novice, you will be able to have your computer up and
running with a minimum of fuss. You will also gain valuable hands-on
experience by following the easy step-by-step instructions. If you are
an advanced user, you will appreciate the affordable power of this
system.
Your system uses an Intel CorporationTM 80386SX microprocessor
which is a 32-bit CPU with a l&bit external data bus and a 24-bit
external address bus. It provides the performance benefits of a 32-bit
programming architecture and the cost savings associated with 16-bit
hardware systems. Moreover, it is 100% object-code compatible with
the 386, 286, and 8086 microprocessors. Therefore, your system optimizes both for performance and cost. It can access the world’s largest
existing microcomputer software base, including the growing collection
of 32-bit software.
Quality, flexibility, and functionality are the key design features of your
system. This system provides optimum performance at an affordable
price.
Operating System
Your computer uses the MS-DOS® operating system. For more details
on this operating system, please refer to the Microsoft® MS-DOS
User’s Guide and User’s Reference. This manual is included with your
system.

1-5 Example of a System Configuration
The basic system is pictured below. You may choose peripherals and
upgrades for the system as your needs require. Even if your system is
different from the one pictured, it should operate in the same basic
manner.

1-6 System Unit
The system unit may house a motherboard, disk drives, a power supply
and an optional expansion cards.

1-7 Control Panel
The control panel provides several useful functions which are explained below. You are likely to use the front panel frequently, so let’s
start there.
figure 14: Front Panel
Reset Button
The reset button allows you to restart the system without turning the
lower off.
If you encounter any problems while using unfamiliar software, you can
always restart quickly from the RAM test stage by pressing the reset
button. Note, however, that any data which have not been saved to
disk will be lost.
Turbo Button
The Turbo button allows you to change the running speed of the
microprocessor to accommodate software requirements. Some
software applications must be run at a slow clock speed.
Indicator Lights
These lights indicate the operation status of your computer.

Chapter 7: System Overview
The green LED
is lit when the power is on.
The yellow LED comes on when Turbo clock speed is ac-
tivated.
The red LED comes on when the hard disk is being ac-
cessed.
Keylock
Chapter 1: System Overview
The keylock enables or disables the keyboard. In the unlock mode the
keyboard is activated. In the lock mode the keyboard is disabled to
deny unauthorized users access to the computer.
Figure 1-5: Keylock and Two Security-Lock Keys

System Power Switch
The system power switch is located on the right side of the case toward
the rear.
Figure 1-6: ON/OFF Switch in OFF Position
You should always be certain that the power is turned off before
modifying the hardware configuration in any way.
10
Chapter 1: System Overview
1-8 Rear Panel
Chapter 1: System Overview
The rear panel has all the connections that lead from the system unit
to external peripherals and the power source. Turn off all power
switches before connecting or disconnecting cables/wires!
sure that cables/wires are attached to the peripheral device first and
connect to the outlet unit later. Turn the system unit power switch off
before you plug the
En-
power cable into an electrical outlet.
Figure 1-7: Rear Panel
11
Keyboard Connector
The keyboard supplied with your system may be plugged into sockets
at the back of the case. Plug the keyboard cable into the socket as
shown below.
Figure 1-8: Connecting the Keyboard Cable
12
Chapter 1: System Overview
Power Cord Connector
The power supply has two receptacles: one supplies power to a
monitor; the other connects to the main power source.
If your monitor power plug does not fit the system unit’s monitor power
outlet, you should plug it into a wall electrical outlet.
Figure 7-9: System Power Cord
I
Chapter 1: System Overview
13
Display Port
You will also need
to connect your monitor to the system unit at a
female display port in one of the expansion slots as shown on the
previous page.
To attach the monitor cable to the display port, plug the cable into the
port and screw the cable connector down securely.
Your computer gives you a wide range of video options to meet your
needs.
You have a wide choice of the following video standards.
- MGA (Monochrome Graphics Adapter) also referred to as
Hercules
- CGA (Color Graphics Adapter)
- EGA (Enhanced Graphics Adapter)
- VGA (Video Graphics Adapter)
Refer to the figures below for mono and color display connectors.
