Changing the processor speed

Controlling the speaker.

Locking the Computer’s Cover

You can lock the cover onto the computer to prevent unauthorized users from accessing its internal components. To do this, you need a padlock that fits through the holes in the lock block on the computer’s back panel. When the padlock is in place, the screw securing the cover on the computer cannot be removed.

You can also secure the computer to your work surface by

inserting a cable lock through the lock block holes and then through a secure anchor on your desk or table.

Using Your Computer

1-1

Page 19

To lock the cover, insert a padlock or cable lock through the holes on both sides of the lock block.

To unlock the cover, remove the padlock or cable lock to expose the cover retaining screw.

Using the Password Features

You can set three types of passwords to provide security for your computer:

Power-on password

Network password

Keyboard password.

The power-on password prevents unauthorized users from using your system by requiring you to enter the correct password every time you turn on or reset the computer.

1-2

Using Your Computer

Page 20

The network password modifies the way your power-on password works by allowing your computer to load your operating system and network software before requiring you to enter the correct password. This enables your system to connect to the network, while preventing unauthorized users from typing anything at the keyboard.

The keyboard password allows you to temporarily lock the keyboard without having to reset the computer. This secures your system when you will be away from it for a while. If you set a power-on password, it automatically becomes your keyboard password as well. However, you can set a different keyboard password or set a keyboard password without setting a power-on password.

Follow the instructions in the sections below to set, enter, change, or delete the different types of passwords.

Setting Passwords

There are two ways to set a power-on password:

Using the BIOS SETUP program

Using the EISA System Utilities.

To set a power-on password in SETUP, follow the instructions in the Select the Password option on the second page of SETUP options and follow the instructions on the screen to set a password.

You must run the EISA System Utilities to set a network and keyboard password, but you can also use it to set a power-on password.

Using the SCSI Subsystem

This chapter describes the basic operations you need to perform to use the computer’s built-in SCSI-II subsystem. The SCSI-II subsystem consists of the following components:

SCSI controller for single-ended SCSI devices

Internal SCSI hard disk drive connector

External SCSI device port

External SCSI device terminator.

Your system also comes with SCSI drivers for MS-DOS. You

may need to install these drivers after you have installed your SCSI devices, depending on how you configure the subsystem. See the Software Guide for instructions on installing and using the drivers.

To set up your SCSI subsystem, you need to do the following:

Set SCSI ID numbers for all of your SCSI devices

Install a SCSI terminator on the last external SCSI device

Install or connect the internal and/or external SCSI devices

Format and partition any SCSI hard disk drives

Install the operating system(s) on a SCSI hard disk drive (if you will boot your system from a SCSI drive)

Install and configure any necessary SCSI device drivers.

These operations are described in this chapter.

Note

If you plan to use a SCSI hard disk drive as the drive from which you load your operating system, be sure you set the following options when you configured your system:

Setting the SCSI ID Numbers

Each SCSI device must have a SCSI ID number, from 0 to 7; including the computer’s SCSI built-in controller. The controller is automatically set to ID number 0. You must manually assign a SCSI ID number for each of your SCSI devices.

The system automatically boots from the SCSI device with the lowest ID number, so keep this in mind as you set the ID numbers for your devices.

To assign the ID number for most SCSI devices, you set

jumpers or switches on the device. See the manual that came

with each device for instructions on setting its jumpers or switches.

4-2

Using the SCSI Subsystem

Page 64

Installing the SCSI Terminators

Your configuration of SCSI devices, both internal and external,

will communicate with each other and with the SCSI controller along the SCSI bus. For the SCSI subsystem to operate properly, you must install special resistor packs called terminators to mark the devices on both “ends” of the SCSI bus. The ends of a bus are the first device at one end of the bus (an internal SCSI drive, for example) and the last device on the other end (the last external device on the external cables).

Since the SCSI controller is counted as a device on the SCSI bus,

the first or last device on the bus could be the SCSI controller. For example, if you have installed only an internal SCSI hard disk, the first device on the bus is the hard disk and the last device is the controller.

Terminators are usually installed on the printed circuit board of

a SCSI device. In your computer, the terminator for an internal SCSI hard disk drive is soldered onto the disk drive riser board in your system’s drive housing. Therefore, you do not need to install a terminator if you use an internal SCSI drive. The

terminator for the external end of the SCSI bus came in the box with your computer.

Before you connect devices to the internal or external SCSI

connectors, follow these guidelines to connect the terminators properly:

You must have only two devices with terminators in a SCSI subsystem: the first device on the SCSI bus and the last device. Since all SCSI devices come with terminators, you must remove the terminators from any other devices in the subsystem.

Using the SCSI Subsystem

4-3

Page 65

If you install only an internal SCSI drive, it is automatically

terminated by the circuitry on the disk drive riser board

when you connect the drive to it. You should install the

terminator that came with system to the external SCSI port to terminate the external end of the bus.

If you install external SCSI devices to the computer, follow the instructions in your external SCSI device manuals to install the necessary terminator on the last external device on the bus. The built-in SCSI terminator that is soldered onto the disk drive riser board terminates the internal end of the bus whether or not there is an internal drive installed.

If you connect a SCSI device with a built-in terminator that cannot be removed, it must be the first or last device on the SCSI bus.

Installing or Connecting SCSI Devices

If you will be using an internal SCSI hard disk drive, see Chapter 3 for instructions on installing the drive in your computer (if it is not already installed).

You can connect up to seven external SCSI devices to the external port if you did not install an internal SCSI drive or up to six devices if you did install one. You should connect your external SCSI devices after you install your internal SCSI device and replace the computer’s cover.

You must use the correct shielded SCSI device cables with your

system. See your SCSI device manuals for information about the cables you should use. As a general rule, the shortest cables

enable your SCSI subsystem to operate more efficiently.

Page 66

Formatting and Partitioning a SCSI Hard Disk

Before you can use your SCSI devices, you must logically format the hard disk drives and partition them for use with your operating system(s). Then you can install your operating system files on the drive you will use to boot the computer.

If you are installing MS-DOS, use the FDISK command to

format and partition the drives. If you are using another

operating system along with MS-DOS, be sure to leave room when you run FDISK to create partitions for the other operating

system. See your MS-DOS manuals for instructions on running

FDISK.

If you will be using three or more SCSI hard disk drives with MS-DOS, you will need to install the SCSI device drivers

(described in your

Follow these steps to format and partition SCSI hard disk

drives in a system with three or more SCSI hard disk drives:

Error Messages

Your computer’s built-m memory (ROM) contains a series of diagnostic programs, called power-on diagnostics. These programs check internal devices such as ROM, RAM, the timer, the keyboard controller, and the hard disk drive every time you turn on the computer or press the reset button. The RAM test program displays a count of the memory currently installed in your system.

If the computer finds an error, it reports one of the following types of error messages:

Power-on diagnostic and boot error messages

Error tone codes for fatal errors (that lock up the system)

Error tone codes for non-fatal errors (that do not lock up

the system).

Be sure to write down the error message or tone code pattern

and give the information to your dealer when you report a

problem. These error messages are described below.

Power-on Diagnostic and Boot Errors

When the power-on diagnostic tests detect an error, the

computer displays a message on the screen (as described

below) and the speaker beeps twice. If the error occurs before

the computer initializes the video display, the speaker sounds a series of beeps (described in the next section).

Each error is identified by a message number and a countdown number which the computer uses as it executes the test associated with the error. For example, the following message is countdown number 100 and error message number 0018:

100 (0018):

The computer starts but does not boot.

If the computer starts but does not load your operating system, the problem could be caused by many different factors.

First make sure you have correctly formatted your hard disk and have properly installed your operating system on it. (See

“Hard Disk Problems” on page A-15.) If you do not have a hard disk, insert a system diskette in

drive A and press the reset button.

The computer does not respond when you type.

If you have just turned on the computer, check the following:

Make sure your keyboard is securely connected to the computer.

If you entered the wrong password and cannot access your

system, see “Password Problems” below. If you are running a software program, try these procedures:

If your computer is processing a complicated command or

The computer suddenly stops operating.

Your computer may have stopped operating because its power supply contains detection circuits that automatically shut down the power if they detect excessive operating temperatures. This protects your system from damage due to overheating.

When these circuits detect a high temperature, they shut off all the DC outputs in the power supply and your computer stops operating. This does not damage the power supply, but you must remove the cause of the high temperature before you can use your system again.

To restore normal power supply operation, follow these steps:

Turn off the computer and leave it off for at least 30 seconds to reset the power supply logic.

To determine the cause of the high temperature and correct the condition, check for the following:

A blocked power supply fan. Make sure that nothing blocks the power supply fan vents on the sides of the computer case. Check both inside and outside the computer for blockage. Make sure there is ample room around your system for air circulation.

Room temperatures of 104° F (40° C) or above. If this is the case, move the computer to a cooler area.

An overload of the power supply limitations. Check the information in Appendix B to see if you have exceeded the option slot power limits. See your option card manual for the power requirements of your card(s).

After you eliminate the problem causing the overheating, allow the computer to cool down for at least five minutes at

a room temperature of about 78° F (25° C). This resets the thermal detection circuits.

Troubleshooting A-9

Page 77

If you removed the computer’s cover, replace it now. Then turn on the computer.

If the power supply shuts off again after you follow the steps

above to correct the problem, contact your dealer.

Password Problems

If you set a power-on, network, or keyboard password and you have trouble entering it, check the section below that describes the problem you are having.

You enter the password, but nothing happens.

Type the password again and press [Enter. You have three chances to enter a power-on or network password correctly before the system locks up. If this happens, press the reset button to reboot the computer and try again. You can try as many times as necessary to enter a keyboard password.

You want to change or delete the password.

See Chapter 1 for instructions on changing or deleting your password.

You have forgotten the current power-on password.

If you have forgotten your power-on password and cannot use your computer, follow these steps:

Turn off the computer, remove the cover, and clear the

password by moving the main system board jumper J21

from pins 4-6 to pins 2-4. See Chapter 2 for instructions on

removing the cover and Chapter 3 for instructions on

changing the jumper setting.

Notes: 1

Not all video modes are used at the same time. You can save some memory by defining which video modes you are using. Typically, 0B-0000H to 0B-7FFFH is only used when you attach a monochrome monitor. Both the text and graphic VGA modes are often used when you attach a VGA monitor.

You can remap the video BIOS to 0C-0000H using the SETUP program or the System Configuration utility if your applications require the video BIOS to reside at that location. Do not enable remapping to 0C-0000H unless your application requires it; this saves 32KB of memory for other uses. The built-in video BIOS is always located at 0E-0000H.

You can shadow external ROM BIOS information to memory between 0C-0000H and 0D-FFFFH using the SETUP program or the System Configuration utility. The option allows you to begin the shadow block at each 16KB boundary.

Glossary

Address

A number or name that identifies the location where information is stored in a computer’s memory.

Application program

A software program designed to perform a specific task, such

as a word processing or spreadsheet program.

ASCII

American Standard Code for Information Interchange. A

standardized coding system for representing characters, such as numbers, letters, and graphic symbols. An ASCII character occupies one byte of storage. Many different computers, printers, and programs can use files transmitted in ASCII code.

Asynchronous

A method of data transmission in which one machine sends data one character at a time to another machine at irregular intervals that do not need to be synchronized to a timing device.

AUTOEXEC.BAT file

The batch file that is executed automatically when you load

MS-DOS. See also Batch file.

Base memory

The memory in the computer below 1MB that is available to MS-DOS and application programs-usually 640KB. Also called conventional memory or main memory.

Batch file

A type of file that lets you execute a series of commands by typing one command. Batch files are text files with the filename extension .BAT. When you type the filename, the operating system executes all the commands in that file sequentially.

BIOS

Basic Input/Output System. Routines in ROM (Read Only Memory) that handle basic input/output functions of the operating system, the video controller, and the SCSI controller.

Bit

A binary digit (0 or 1). The smallest unit of computer storage.

The value of a bit represents the presence (1) or absence (0) of an electric charge.

Boot

To load the operating system into the computer’s memory.

Byte

A sequence or group of eight bits that represents one character.

Cache memory

A high-speed type of memory buffer that stores information from base or extended memory where your system can access it faster.

CFG (configuration) file

A file that provides the System Configuration program with all the information it needs about your system board or an option card. All EISA cards and some ISA cards come with CFG files.

CGA

Color Graphics Adapter. A type of display adapter card that can generate up to 25 lines of text with 80 characters on each line, monochrome graphics at 640 x 200 resolution, or fourcolor graphics at 320 x 200 resolution.

CMOS

Complementary Metal-Oxide Semiconductor. A type of low-power silicon chip.

Command prompt

The symbol or message that tells you your operating system is loaded and ready to receive instructions. The default command prompt displays the current drive and directory. If you are logged onto drive C, the command prompt may look like this: c:>.

Configuration

The particular setup of a group of components. A typical system configuration consists of a computer with one diskette drive and one hard disk drive connected to a monitor and a printer.

Control code

A command (generated when you hold down m and press another key on the keyboard) that instructs the computer to perform a specific function.

Coprocessor

An optional device that enables the computer to process certain

mathematical calculations faster.

CPU

Central Processing Unit. The primary unit of the computer that interprets instructions, performs the tasks you indicate, keeps track of stored data, and controls all input and output operations.

Cylinders

The vertical alignment of tracks in a hard disk that can be lined

up under one read/write head. The number of tracks on a disk is equal to the number of cylinders times the number of heads.

Information such as text or graphics stored or processed by a computer.

Default

Any value or setting that takes effect when the computer is turned on or reset. A default value stays in effect unless you override it temporarily by changing a setting or you reset the default value itself.

Device driver

A file containing instructions that allow your computer to recognize and control a device.

Diagnostics

See Power-on diagnostics and System diagnostics.

DIP switch

Dual Inline Package switch. A small switch on a computer, option card, or printer that controls a particular function.
