Overview
Computer Configuration This powerful computer is based on the high-perforinance 16-bit Intel 80286
microprocessor. It is functionally compatible both in hardware and software
with the IBM PC AT. The minimum configuration offers the following
features:
•640K RAM (random-access read-write memory).
•A 1.2MB half-height high-density diskette drive
•A disk-controller board with connections for two diskette drives and two
hard-disk drives (for a maximum of three drives that can be installed at one
time inside the system)
•Eight 1/0 (input/output) expansion slots
•A serial/parallel adapter board
•A battery-backed real-time clock
•Dual-speed processor board operation either at the standard IBM PC
AT-compatible speed or a higher speed
•An international power supply with a choice of 115 or 230 volts
•Battery-backed CMOS, which holds your system configuration
•Choice of an 84-key or 102-key ergonomic keyboard
To these features, you can add any of several display adapter boards and
monitors:
•A monochrome display adapter (with or without graphics) and a
monochrome monitor
•A high-resolution monochrome display adapter (with graphics) and a
high-resolution monochrome monitor
•A medium-resolution color display adapter and RGB color monitor
•An enhanced graphics display adapter (EGA) and high-resolution color
monitor
•A graphics display adapter (GDA) that combines on one board the functions
of several different video display adapters
Your computer plus the monitor and display adapter board of your choice
make up your system. Figure 1 shows the minimum system.

Among the many options that can be added to this minimum system are the
following:
•One or two hard-disk drives of varying storage capacities
•A second diskette drive, either 1.2MB or 360K
• Memory expansion boards
•An 80287 math coprocessor
•A second serial/parallel board
•A floor stand
The computer comes with the MS-DOS operating system, a standard
operating system for microcomputers. The operating system controls what
yciu can do with a computer and how you do it. You'll find the diskettes
containing the operating system files in a packet with the manuals.
■Note—Only MS-DOS and IBM DOS versions 3.0 or greater will run on this
computer.
iv Overview

If you have a system with a hard disk, the operating system files are already
installed on the hard disk. For more information about MS-DOS, refer to
Chapter 6, "Getting Started with MS-DOS," and to the MS-DOS Guide.
Documentation Package
Contents
Your computer was shipped with the following documentation and diskettes:
•User's Guide
•MS-DOS Guide
•GW-BASIC Guide
•One Setup and Test Diskette
•Two MS-DOS system diskettes
The following are brief descriptions of the manuals that come with your
computer:
•User's Guide —Introduces you to all of the basic components of your new
computer system. Chapters 1 through 8 comprise a tutorial that shows you
how to assemble the components and get started with MS-DOS.
The remainder of the manual serves as a reference guide for the computer
hardware. It gives instructions on how to install options to make the
computer more powerful, how to set up the system and run system tests, and
how to install serial and parallel devices.
• MS-DOS Guide —Shows you how to get the most out of the operating
system. It explains all the commands and utility programs in the operating
system and has valuable information on the many special features of
MS-DOS.
• GW-BASIC Guide—Contains information on all of the BASIC commands,
statements, and functions, as well as some fundamental programming tips. If
you are interested in programming, this reference guide for the GW-BASIC
programming language will be very helpful.
Overview v

Software Compatibility
Hardware Compatibility
The following are brief descriptions of the three diskettes that accompany
your computer:
• MS-DOS System Diskettes —Contain the-MS-DOS command files, the system
utility programs, and the GW-BASIC programming language
•Setup and Test Diskette—Contains the SETUP program, which allows you to
configure system options, and a series of tests for the computer system
Because your computer operates under MS-DOS, you have access to the
rapidly growing library of MS-DOS-based IBM PC AT-compatible applications
software programs, including popular spreadsheet, database, word-processing,
and integrated packages. In addition, you can find many MS-DOS-based
programs for accounting, communications, graphics, idea processing, time
management, leisure-time, and much more. Your dealer can help you select
the programs that fit your needs.
■Note—If you run any operating system other than MS-DOS on your computer,
refer to the documentation for that operating system for information about
software compatiblity.
The expansion slots in your computer are IBM PC AT-compatible. This
means that vou can attach many different accessories that are available for the
IBM PC AT. These include boards for networking communications and
internal modems. Your dealer can help you choose the accessories that are
best for your system. •

How to Use This Manual
Paths for Different Users
This User's Guide is intended to answer any fundamental questions you may
have about your computer. It also touches on the subjects of operating
systems in general and the MS-DOS operating system in particular. A detailed
examination of these subjects is contained in the MS-DOS Guide.
The manual is divided into two parts, "Part 1—Getting Started: A Tutorial,"
and "Part 2—Reference Guide." The purpose of Part 1 is to guide you
through getting your computer system up and running. Some of the things
covered are
•The unpacking stage
•The connection of the various components into a complete computer system
•A general introduction to the MS-DOS operating system
When you finish Part 1, your system will be properly assembled, and you'll
have enough knowledge about the computer and the MS-DOS operating
system to run an MS-DOS-based applications software program.
Part 2 provides reference information about the computer hardware and
getting the most out of your system.
Different users with different needs will be seeking information from the
pages of this User's Guide, so a Quick-Reference Table is included here to put
them on the right path (Table I). Regardless of your computer experience,
this table will help you quickly access the parts of this manual that you
specifically need. (It also refers you to the MS-DOS Guide.)
Nine categories of users are defined and addressed in three different divisions
in this Quick-Reference Table. The three divisions are
• Assembly—The state of assembly in which you find the system
• Drives—The number and types of drives included in your system
• Experience—Your computer experience
You'll find yourself in at least two of these divisions; you may also find
yourself in more than one category within a division.

How to Use This Manual ix

Manual Conventions You should be familiar with the conventions that are followed in this User's
Guide before you start:
•References to keyboard keys are always shown in uppercase letters, though
the actual keys may be labeled with both uppercase and lowercase letters
and/or with a symbol. Examples: ESC for the Esc (or escape) key and
BACKSPACE for the<— key.
•Although the text usually shows data that you enter from the keyboard in
uppercase letters, you can type it in lowercase. MS-DOS does not distinguish
between uppercase and lowercase.
•In Part 1, you are directed to press the ENTER key when you want the
computer to accept commands and other information that you have typed
in. This step is usually necessary in MS-DOS.
•The tutorial uses the ENTER key as the most convenient key to press when
ascreen message refers to "any key."
• Computer refers to the main computer unit. Depending on the context, system
refers to the computer together with the monitor of your choice, or to any
operating system.
•The expression disk drives refers to hard-disk drives and diskette drives
considered together.
• Disk drives are often referred to by the following drive designations: Drive Ais
the first or only diskette drive; drive B is the second diskette drive; drive C is
the first or only hard-disk drive; drive Dis the second hard-disk drive.
•Unless otherwise indicated, numbers can be entered from either the
alphanumeric portion of the keyboard or the numeric keypad. However, for
numbers to be entered from the numeric keypad, the NUM LOCK key must
be engaged.
