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 equip-
ment generates, uses and can radiate radio frequency energy and it not installed and used
in accordance with the instructions, may cause harmful interference to radio communica-
tions. 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.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
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 radii and t&vision 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 am 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 apparautus as set out in the radii interference regulations of the Canadian
Department of Communication.
Le Présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites
applicables aux apparels numériques de Class B preescrites dans le réglement sur le
brouillage radiélectrique édicté parte Ministére des Communications du Canada.

Warning
• Your warranty be voided if you open your system unit case
up to reconfigure the system.
• If you wish to reconfigure the computer at any time, ensure that
the power is turned OFF before changing any hardware set-
tings, such as DIP switches or jumpers.

System Overview

System Overview
This chapter covers:
■
the basics of your system
■
the system’s features and specifications
control panel features and connectors outside the case
■
how to maintain your computer
lf you are an experienced user who wants to get to work as soon as
possible, the Quick Start section at the beginning of this chapter
provides you all the information you need to set up the hardware.
If you want to upgrade your hardware later, read Chapter 2.
If you want to gain a more thorough understanding of your computer,
read the entire manual.
Note:
You may refer to the Glossary chapter for definitions of computer
terminology.
Chapter 1: System Overview

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.
lf you are a novice, you will have your computer up and running with a
minimum of fuss. You will also gain valuable handson experience by
following the easy step-by-step instructions. If you are an advanced
user, you will appreciate the affordable power of this system.
The 386-based mainboard provides superlative performance and com-
plete compatibility with software written for the Intel ‘86 family of CPUs.
The system uses a cache memory subsystem providing a small
amount of fast memory (SRAM) and a large amount of slow memory
(DRAM). This system is configured to so that all system memory is fast
-fast enough to support burst cycles and to complete bus cycles with
no wait states. The cache memory provides high performance at a
cost approaching that of DRAM.
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.
