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 computer is compatible with the PC/AT This means that virtually all the software available for the PC/AT can also be run on your computer. Moreover, the keyboard commands used on a PC/AT can also be used on your computer. For example, the same

functionality are the key design features of your computer. For this dable AT-style power.

The clear, well-illustrated instructions in this manual ensure that even

<Ctrl>

<Alt>

<Del> combination of keystrokes used for the software reset on the

PC/AT may also be used on your computer. Quality, flexibility, and reason, this computer is the ideal choice for a person seeking affor-

if you are a newcomer to the computer world, you will have your computer installed and running with a minimum of effort.

Reset Button

The reset button allows you to restart the system without turning the power 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. software applications must be run at a slow clock speed.

Indicator Lights

Two lights indicate the operation status of your computer. The green LED is lit when the power is on. The red LED comes on when the hard disk is being accessed.

The power supply has two receptacles: one supplies power to a

monitor; the other connects to the main power source.

Yet, 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 1-9: System Power Cord

Chapter 1: System Overview

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.
