Euro Sign Support Information

The Euro Sign is the name given to the proposed currency symbol of the
European Union. According to the European Commission, the Euro will
exist as a currency beginning 1 January 1999, but will only gradually move
into general use with the introduction of coins and notes in 2002.

IBM and various other personal computer industry companies plan to
support the Euro Sign on products released in 1999. For support
information on products released prior to that date, see the appropriate
Web site for your product.

For your computer to support the Euro Sign, a proper combination of both
hardware (computer, keyboard, and printer) and software (operating
systems, application programs, and device drivers) is required.

There are many Web sites that provide Euro Sign information and support
(some are listed below). First, determine the computer hardware and
software you are using. Then, visit the Web sites that apply to your system
for the latest Euro Sign information and support. In many cases, updates
are available for Euro Sign support. These updates can be downloaded and
installed on your computer.

Chapter 3. Arranging Your Workspace

To get the most from your computer, arrange both the equipment you use
and your work area to suit your needs and the kind of work you do. Your
comfort is of foremost importance, but light sources, air circulation, and the
location of electrical outlets also can affect the way you arrange your
workspace.

Comfort

Although no single working position is ideal for everyone, the following
guidelines will help you find a position that suits you best.

Choose a good chair to reduce the frequency of fatigue from sitting in the
same position for a long time. The backrest and seat should adjust
independently and provide good support. The seat should have a curved
front to relieve pressure on the thighs. Adjust the seat so that your thighs
are parallel to the floor and your feet are either flat on the floor or on a
footrest.

When using the keyboard, keep your forearms parallel to the floor and your
wrists in a neutral, comfortable position. Try to keep a light touch on the
keyboard and your hands and fingers relaxed. You can change the angle of
the keyboard for maximum comfort by adjusting the position of the
keyboard feet.

Viewing Distance

Lower
Back
Support

Seat
Height

Adjust the monitor so that the top of the screen is at, or slightly below, eye
level. Place the monitor at a comfortable viewing distance, usually 51 to 61
cm (20 to 24 in.), and position it so you can view it without having to twist
your body.

 Copyright IBM Corp. 1998 17

Glare and Lighting

Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Place the monitor at right angles to
windows and other light sources whenever possible. Reduce overhead
lighting, if necessary, by turning off lights or using lower wattage bulbs. If
you install the monitor near a window, use curtains or blinds to block the
sunlight. You might have to adjust the Brightness and Contrast controls on
the monitor as the room lighting changes throughout the day.

Where it is impossible to avoid reflections or to adjust the lighting, place an
antiglare filter over the screen. However, these filters might affect the
clarity of the image on the screen; try them only after you have exhausted
other methods of reducing glare.

Dust buildup compounds problems associated with glare. Remember to
clean your monitor screen periodically using a soft cloth moistened with a
nonabrasive liquid glass cleaner.

Air Circulation

Your computer and monitor produce heat. The computer has a fan that
pulls in fresh air and forces out hot air. The monitor lets hot air escape
through vents. Blocking the air vents can cause overheating, which might
result in a malfunction or damage. Place the computer and monitor so that
nothing blocks the air vents; usually, 51 mm (2 in.) of air space is sufficient.
Also, make sure the vented air is not blowing on someone else.

Electrical Outlets and Cable Lengths

The location of electrical outlets and the length of power cords and cables
that connect to the monitor, printer, and other devices might determine the
final placement of your computer.

When arranging your workspace:

 Avoid the use of extension cords. Whenever possible, plug the

computer power cord directly into an electrical outlet.

 Keep power cords and cables neatly routed away from walkways and

other areas where they might be kicked accidentally.

For more information about power cords, see “Power Cord Notice” on
page 152.

18 PC 300GL User Guide

Chapter 4. Operating Your Computer

This chapter provides information to help you in the day-to-day use of your
computer.

Important Information

 When the power cord is first plugged in, the computer might

appear to power on for a few seconds, then power off. This is a
normal sequence.

 The power switch will normally operate with a single touch.

However, in some circumstances the computer might not
immediately power off. In this case, hold the power switch down
for approximately 5 seconds. The computer will then turn off.

 Always shut down your operating system before turning off the

computer. Refer to your operating system documentation for the
proper procedure to shut down your operating system.

 Proper cooling is required for the reliable performance of internal

components. Do not operate your computer with the cover off.

Starting Your Computer

What you see and hear when you start up your computer depends on the
settings in the Start Options menu of the Configuration/Setup Utility
Program. The default settings are Power On Status [Disabled] and Power

On Self Test [Quick].
Note: Other selections also might change what is displayed when the

computer starts up.

The following briefly describes what happens in the default mode when
you turn on your computer:

1. The IBM logo appears.

2. The amount of system memory and extended memory appears in the
top-left corner of screen.

3. The Press F1 for Configuration/Setup prompt appears.

4. If any errors were detected during POST, they are displayed.

5. If you have set a power-on password, a prompt appears on the screen.
If you have set both power-on and administrator passwords, you can
type either password at the password prompt. When you type your
password at the prompt and press Enter, the first screen of your
operating system or application program appears.

 Copyright IBM Corp. 1998 19

6. If the system hardware configuration has changed, the
Configuration/Setup Utility Program menu may be displayed when
you press Enter.

For more information, see “Power-On Self-Test (POST)” on page 86.

If Power On Status is [Enabled], and the power-on self-test (POST) finishes
without detecting a problem, you hear one beep. If POST detects a problem
when you start your computer, you hear multiple beeps or no beep. In
most cases, an error code appears in the top-left corner of the screen, and in
some cases a description of the error is displayed beside the code. (Note
that the screen will sometimes display multiple error codes and
descriptions.) Write down all error code numbers and descriptions.

If Power On Self Test is [Enhanced], numbers showing the amount of
memory being tested appear in the top-left corner of the screen until the
total amount of memory in the system is reached. Prompts for running a
fast POST or accessing the Configuration/Setup Utility Program appear in
the lower-left corner of the screen.

Shutting Down

When you are ready to turn off your computer, follow the shutdown
procedure for your operating system to prevent the loss of unsaved data or
damage to your software programs. See your operating system
documentation for instructions.

Using System-Management Features

This section describes features that enable a network administrator or file
server to remotely manage and control your computer. For more
information about system management, refer to Understanding Your Personal
Computer (provided on the Software Selections CD that comes with your
computer).

20 PC 300GL User Guide

Desktop Management Interface

Desktop Management Interface (DMI) is a method for gathering information
about the hardware and software in your computer. In a network
environment, network administrators can use DMI to remotely monitor and
control your computer. For more information about DMI, refer to
Understanding Your Personal Computer (provided on the Software Selections
CD that comes with your computer).

Wake on LAN

The Wake on LAN feature requires a Wake on LAN network card. A
network administrator can use this feature to turn on your computer from a
remote location. When Wake on LAN is used in conjunction with
network-management software, such as Netfinity (provided on the Software
Selections CD that comes with your computer), many types of functions,
such as data transfers, software updates, and POST or BIOS updates to your
computer can be initiated remotely. For more information, see the
documentation that comes with your Ethernet adapter.

Note: If the computer power cord is plugged into a surge protector, make

sure that when you turn off power you use the computer power
switch and not the surge protector switch. Otherwise, the Wake on
LAN feature will not work.

Wake on Ring

The wake on ring feature can be used to turn on your computer when a
wake on ring supported modem receives a call from the telephone line to
which it is connected. It is configured in the Configuration/Setup Utility
Program.

Remote Program Load or Dynamic Host Configuration
Protocol

If your computer comes with an Ethernet adapter, a network administrator
can use Remote Program Load (RPL) and Dynamic Host Configuration
Protocol (DHCP) to control your computer. If you use RPL in conjunction
with software such as LANClient Control Manager, you can use a feature
called Hybrid RPL, which installs hybrid images (or files) on the hard disk.
Then, each time the computer starts from the network, LANClient Control
Manager recognizes your computer as a Hybrid RPL client and a bootstrap
program is downloaded to your computer hard disk. This bootstrap
program is small, which helps prevent network congestion. An advantage
to Hybrid RPL is that the network traffic associated with a standard RPL is
avoided.

Chapter 4. Operating Your Computer 21

Remote Administration

A network administrator can use this feature to update remotely the POST
and BIOS in your computer. Network-management software, such as
LANClient Control Manager, is required in order to take advantage of this
feature. Refer to “Setting Remote Administration” on page 38 for
configuration information.

Using Video Features

Your computer has a super video graphics array (SVGA) advanced graphics
port (AGP) controller located on the system board. SVGA is a video
standard for displaying text and graphic images on a monitor screen. Like
other video standards, SVGA supports a variety of video modes. Video
modes are different combinations of resolution, refresh rate, and color
defined by a video standard for displaying text or graphics. For more
information on video modes, refer to Understanding Your Personal Computer
(provided on the Software Selections CD that comes with your computer).

Video Device Drivers

To take full advantage of the graphics adapter in your computer, some
operating systems and application programs require custom software,
known as video device drivers. These device drivers provide support for
greater speed, higher resolution, more available colors, and flicker-free
images.

Device drivers for the graphics adapters and a README file with
instructions for installing the device drivers are provided on the Software
Selections CD that comes with your computer. If your computer has
IBM-preinstalled software, video device drivers have already been installed
on the hard disk. However, you can use the device driver installation
instructions if you ever need to reinstall the device drivers; if you want to
change video resolution, color depth, or monitor settings; or if you need
information on obtaining and installing updated device drivers.

See Chapter 9, “Getting Help, Service, and Information” on page 123 for
more information.

22 PC 300GL User Guide

Changing Monitor Settings

To get the best possible image on your screen and to reduce flicker, you
might need to reset the resolution and refresh rate of your monitor. You
can view and change monitor settings through your operating system, using
the instructions provided in the README files on the Software Selections CD
that comes with your computer. Refer to your operating system
documentation for further information on monitor settings.

Attention

Before you change any monitor settings, be sure to review the
information that comes with your monitor. Using a resolution or
refresh rate that is not supported by your monitor might cause the
screen to become unreadable and could damage the monitor. The
information that comes with your monitor usually includes the
resolutions and refresh rates that the monitor supports. If you need
additional information, contact the manufacturer of the monitor.

To minimize screen flicker and jitter, set your monitor for the highest
noninterlaced refresh rate that the monitor supports. If your monitor
complies with the VESA Display Data Channel (DDC) standard, it is
probably already set to the highest refresh rate that the monitor and video
controller can support. If you are not sure if your monitor is
DDC-compliant, refer to the documentation provided with the monitor.

Using Audio Features

Some models have an integrated ESS 1938 audio controller that supports
Sound Blaster applications and is compatible with the Microsoft Windows
Sound System. Your computer also has a single internal speaker and three
audio ports. The audio controller provides you with the ability to play back
and capture sound and music, and with the internal speaker you can enjoy
sound with multimedia applications. Optionally, you can connect two
stereo speakers to the audio connectors to enjoy better sound with
multimedia applications.

The audio connectors in your computer are 3.5 mm (1/8-in.) mini-jacks. A
description of the connectors follows. (For the location of the connectors,
refer to “Connecting Computer Cables” on page 10.)

Headphone: This jack is used to send audio signals from the computer to

external devices, such as stereo-powered speakers with built-in
amplifiers, headphones, multimedia keyboards, or the Audio
Line-In jack on a stereo system.

Chapter 4. Operating Your Computer 23

Note: The internal speaker in your computer is disabled when

an external speaker is connected to the headphone port
on your computer.

Audio Line Out: This jack is used to send audio signals from the computer

to external devices, such as stereo-powered speakers with
built-in amplifiers, headphones, multimedia keyboards, or the
Audio Line-In jack on a stereo system.

Microphone: This port is used to connect a microphone to your computer

when you want to record voice or other sounds on the hard
disk. This port can also be used by speech recognition
software.

Note: If you experience interference or speaker feedback while

recording, try reducing the microphone recording
volume (gain).

Procedures for recording and playing back sound vary by operating system.
Refer to your operating system documentation for information and
instructions.

Updating System Programs

System programs are the basic layer of software built into your computer.
They include the power-on self-test (POST), the basic input/output system
(BIOS) code, and the Configuration/Setup Utility Program. POST is a set of
tests and procedures that is performed each time you turn on your
computer. BIOS is a layer of software that translates instructions from other
layers of software into electrical signals that the computer hardware can
understand. You can use the Configuration/Setup Utility Program to view
and change the configuration and setup of your computer.

Your computer system board has a module called electrically erasable
programmable read-only memory (EEPROM, also referred to as flash memory).
You can easily update POST, BIOS, and the Configuration/Setup Utility
Program by starting your computer using a flash update diskette or by
using the Remote Administration feature, if enabled. See “Setting Remote
Administration” on page 38 for more information.

As part of the continuing work to improve quality, IBM might make
changes and enhancements to the system programs. When updates are
released, they are available as downloadable files on the World Wide Web
or through the PC Company Bulletin Board Service (see Chapter 9, “Getting
Help, Service, and Information” on page 123). Instructions for using the
system programs updates are available in a README file included in the
update files.

to use your computer. However, if you decide to set one, read the
following sections before you do so.

Power-On Password

Prompt Modes

The power-on password feature deters unauthorized persons from gaining
access to the information stored in your computer. You do not need to set
a power-on password, but doing so allows you to control who can use your
computer. When a power-on password is set, you must type the password
at a prompt that appears as the computer starts.

When you set the power-on password, you can choose one of three
password prompt modes:

On In password prompt On mode, you are prompted for the

power-on password when you turn on the computer. Until the
correct password is entered, the computers operating system
will not start, and the keyboard will remain locked. If you
have a mouse connected to the mouse port, it also will remain
locked. If you have a mouse connected to a serial port, it will
be activated when the computer is started, regardless of
whether a password is set.

32 PC 300GL User Guide

Note: If Remote Administration is enabled, you cannot select

On. In this case, select Dual. If you set this mode to
On, when Remote Administration is enabled, it will

automatically be reset to Dual. For more information,
see “Setting Remote Administration” on page 38.

Off In password prompt off mode (sometimes referred to as

unattended start mode), you are not prompted to enter your
power-on password when you turn on the computer. The
computer will start the operating system. However, if you
have a mouse connected to the mouse port, refer to the
following:

Important Information for Mouse Users

This information applies only to those who have a PS/2
mouse. A serial mouse is not affected by the password
prompt Off mode.

Password prompt Off mode is useful for network servers
and other computers that operate unattended. If a power
failure occurs, the computer will automatically restart and
resume operating when power is restored without operator
intervention.

The password prompt Off mode prevents the computer
from detecting a PS/2 mouse. In this mode, the mouse
device driver will not be loaded automatically through the
CONFIG.SYS or AUTOEXEC.BAT files. An error message
informs you that the mouse connector is disabled.

If you are using Windows NT, Windows 95, or Windows
98, when the computer is started and the
mouse-port-disabled error message appears, type either
your power-on or administrator password to enable the
keyboard. The mouse remains disabled. Use the keyboard
to put a check mark in the Do not display this message in
the future check box. When the operating system
completes its loading routine, the mouse will be enabled.

If you have an operating system other than Windows 95,
Windows 98, or Windows NT, check the documentation
that comes with your operating system to enable the mouse
on your computer.

Dual In the password prompt Dual mode, the startup behavior of the

computer depends on whether the computer is started from the

Chapter 6. Taking Care of Your Computer

This section provides guidelines for the proper handling and care of your
computer.

Basics

Here are some basic points about keeping your computer functioning
properly:

 Keep your computer in a clean, dry environment. Make sure it rests on

a flat, sturdy surface.

 Do not place items on top of the monitor or cover any of the vents in

the monitor or computer. These vents provide air flow to keep your
computer from overheating.

 Keep food and drinks away from all parts of your computer. Food

particles and spills might make the keyboard and mouse sticky and
unusable.

 Do not get the power switches or other controls wet. Moisture can

damage these parts and cause an electrical hazard.

 Always disconnect a power cord by grasping the plug, not the cord.

Cleaning Your Computer

It is a good practice to clean your computer periodically to protect the
surfaces and ensure trouble-free operation.

CAUTION:
Be sure to turn the computer and monitor power switches off before
cleaning the computer and monitor screen.

Computer and Keyboard

Use only mild cleaning solutions and a damp cloth to clean the painted
surfaces of the computer.

 Copyright IBM Corp. 1998 49

Monitor Screen

Do not use abrasive cleaners when cleaning the surface of the monitor
screen. The screen surface is easily scratched, so avoid touching it with
pens, pencil points, and erasers.

To clean the screen surface, wipe it gently with a soft, dry cloth, or blow on
the screen to remove grit and other loose particles. Then use a soft cloth
moistened with a nonabrasive liquid glass cleaner.

Mouse

If the pointer on the screen does not move smoothly with the mouse, you
might need to clean the mouse. To clean your mouse:

1. Turn off the computer.

2. Disconnect the mouse cable from the computer.

3. Turn the mouse upside down. Unlock the retainer on the bottom of
the mouse by moving it in the direction indicated by the arrow on the
retainer.

4. Turn the mouse right-side up, and the retainer and ball will drop out.

5. Wash the ball in warm, soapy water, and dry it well.

6. Using a damp cloth, wipe the outside of the mouse and the retainer.
Be sure to wipe the rollers inside the mouse.

7. Insert the ball and retainer. Lock the retainer by moving it in the
opposite direction of the arrow.

8. Reconnect the mouse cable to the computer.

50 PC 300GL User Guide

Moving Your Computer

units to avoid damage.

Replacing the Battery

Your computer has a special type of memory that maintains the date, time,
and settings for built-in features, such as serial- and parallel-port
assignments (configuration). A battery keeps this information active when
you turn off the computer.

The battery requires no charging or maintenance throughout its life;
however, no battery lasts forever. If the battery fails, the date, time, and
configuration information (including passwords) are lost. An error message
is displayed when you turn on the computer.

Refer to “Lithium Battery Notice” on page ix for information about
replacing and disposing of the battery.

If you replace the original lithium battery with a heavy-metal battery or a
battery with heavy-metal components, be aware of the following
environmental consideration. Batteries and accumulators that contain heavy
metals must not be disposed of with normal domestic waste. They will be
taken back free of charge by the manufacturer, distributor, or representative,
to be recycled or disposed of in a proper manner.

Chapter 6. Taking Care of Your Computer 51

For further information on battery disposal, call IBM at 1-800-IBM-4333
(1-800-426-4333) in the U.S. For information outside of the U.S., contact

Handling Static-Sensitive Devices

Static electricity, although harmless to you, can seriously damage computer
components and options.

Important

When you add an option, do not open the static-protective package
containing the option until you are instructed to do so.

When you handle options and other computer components, take these
precautions to avoid static electricity damage:

 Limit your movement. Movement can cause static electricity to

build up around you.

 Always handle components carefully. Handle adapters and

memory-modules by the edges. Never touch any exposed circuitry.

 Prevent others from touching components.
 When you install a new option, touch the static-protective package

containing the option to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds.
This reduces static electricity in the package and your body.

 When possible, remove the option and install it directly in the

computer without setting the option down. When this is not
possible, place the static-protective package that the option came in
on a smooth, level surface and place the option on it.

 Do not place the option on the computer cover or other metal

surface.

Adapter Configuration

Along with the documentation that comes with your adapter, use the
following information to help with adapter configuration.

Chapter 7. Installing Options 69

Plug and Play Adapters

Plug and Play is a configuration method that makes expanding your
computer easier. Support for Plug and Play is built into the system board
of your computer.

A Plug and Play adapter has no switches or jumpers that must be set. A
Plug and Play adapter comes with configuration specifications set in
memory. These specifications provide installation information to the
computer during startup. When you install or remove Plug and Play
adapters, this information is interpreted by the basic input/output system
(BIOS), which supports Plug and Play technology. If the required resources
are available, the BIOS software automatically configures the adapter using
resources not already used by other devices.

Adapters designed for PCI slots are Plug and Play devices. Most ISA
adapters are not Plug and Play and are referred to as legacy adapters. See
“Legacy Adapters.”

Note: See Chapter 8, “Troubleshooting” on page 85 for information on

error messages resulting from resource conflicts.

Legacy Adapters

Adapters that are not Plug and Play are known as legacy adapters. If you
install a legacy adapter, you must manually configure it by setting switches
or jumpers on the adapter and by reserving its resources using the
Configuration/Setup Utility Program.

In the Configuration/Setup Utility Program, the ISA Legacy Resources
screen shows the computer resources that are typically required by
adapters:

 Memory resources

 I/O port resources
 DMA resources
 Interrupt resources

Working with Internal Drives

This section provides information and instructions for installing and
removing internal drives.

When you install an internal drive, it is important to note what type and
size of drive you can install in each bay. Also, it is important to correctly
connect the internal drive cables to the installed drive.

Internal Drives

Internal drives are devices that your computer uses to read and store data.
You can add drives to your computer to increase storage capacity and to
enable your computer to read other types of media. Some of the different
drives available for your computer are:

 Diskette drives

 Hard disk drives
 Tape drives
 CD-ROM drives

 Zip drives and other removable media drives

Internal drives are installed in bays. Within this book, the bays are referred
to as bay 1, bay 2, and so on.

Your computer comes with the following IBM-installed drives:

 A CD-ROM drive in bay 1 (some models).

 A Zip drive in bay 2 (some models).

 A 3.5-inch diskette drive in bay 3.

 A 3.5-inch hard disk drive in bay 4.

Models that do not have drives installed in bays 1 and 2 have a static shield
and bay panel installed.

Chapter 7. Installing Options 71

Bay 1 (5.25 inch drive)
Bay 2 (3.5 inch drive)
Bay 3 (3.5 inch floppy drive)
Bay 4 (hard disk drive)

Power and Signal Cables for Internal Drives

Your computer uses cables to connect integrated drive electronics (IDE)
drives to the power supply and system board. The following cables are
provided:

 Four-wire power cables connect most drives to the power supply. At the

end of these cables are plastic connectors that attach to different drives;
these connectors vary in size. Also, certain power cables attach to the
system board.

 Flat signal cables for connecting IDE and diskette drives to the system

board; signal cables are sometimes called ribbon cables. There are two
sizes of ribbon signal cables that come with your computer:

– The wider signal cable has two or three connectors.

- If the cable has three connectors, one of these connectors is
attached to the drive, one is a spare, and the third attaches to
the secondary IDE connector on the system board.

- If the cable has two connectors, one of these connectors is
attached to the hard disk drive, and the other attaches to the
primary IDE connector on the system board.

Note: If you want to add another device, and the signal cable

has only two connectors, you will need a signal cable
with three connectors.

– The narrower signal cable has two connectors for attaching the

diskette drive to the diskette-drive connector on the system board.

Note: To locate connectors on the system board, see “Identifying Parts on

the System Board” on page 62.

The following are some important points to remember when connecting
power and signal cables to internal drives:

 The drives that are preinstalled in your computer come with power and

signal cables attached. If you replace any drives, it is important to
remember which cable is attached to which drive.

 When you install a drive, ensure that the drive connector at the end of

the signal cable is always connected to a drive; also, ensure that the
drive connector at the other end is connected to the system board. This
reduces electronic noise from the computer.

 If two IDE devices are used on a single cable, one must be designated

as the primary or master device and the other as the secondary or
subordinate device; otherwise, some of the IDE devices might not be
recognized by the system. The primary or secondary designation is
determined by switch or jumper settings on each IDE device.

Chapter 7. Installing Options 73

 If two devices are on a single cable, and only one is a hard disk drive,

the hard disk drive must be set as the master device.

 If you have only one device on a cable, it must be set as master.

For help in selecting drives, cables, and other options for your computer, do

Chapter 8. Troubleshooting

This chapter describes diagnostic tools that are available to you. You can
use these tools to identify and correct problems that might come up as you
use your computer. This chapter also contains information about option
diskettes and how to recover from a BIOS update failure.

Note: If your computer does not start when you press the power switch,

do the following:

 Make sure all cables are securely connected to the correct

locations.

 Make sure the computer cover is installed properly (pushed all

the way on).

If this does not correct the problem, have the computer serviced.

Using Diagnostic Tools

Computer problems can be caused by hardware, software, or user error (for
example, pressing the wrong key). You can use the diagnostic aids
discussed in this chapter to help you solve such problems yourself or gather
helpful information you can pass on to a service technician.

You can check the hardware by following the procedures in this chapter.
You can also use the diagnostic programs provided with your computer
(see “IBM Enhanced Diagnostics” on page 118 for a description of these
programs).

If the hardware checks out, and you have not made a user error, you might
have a software problem. If you suspect that you have a software problem
and your computer came with IBM-preinstalled software, see the About
Your Software publication and the operating system documentation supplied
with your computer. If you have installed software applications yourself,
see the documentation supplied with the software.

The following tools are available to diagnose hardware-related problems:

Power-On Self-Test (POST)

Each time you turn on your computer, it performs a series of tests that
check the operation of the base computer. This series of tests is called the
power-on self-test (POST).

POST does the following:

 Checks basic system-board operations
 Checks the memory operation
 Compares the current system configuration with that established by the

Configuration/Setup Utility Program

 Starts the video operation
 Verifies that the diskette drives are working
 Verifies that the hard disk drive and the CD-ROM drive are working

If Power-On Self-Test is set to [Enhanced], numbers showing the amount of
memory being tested appear in the top-left corner of the screen until the
total amount of memory in the system is reached. Options for running a
quick POST or accessing the Configuration/Setup Utility Program appear in
the lower-left corner of the screen. Quick mode is the default mode of
operation.

Note: The amount of available memory shown might be somewhat less

than expected because of basic input/output system (BIOS)
shadowing in random access memory (RAM).

If POST finishes without detecting any problems, the first screen of your
operating system or application program appears if you have not set a
power-on password. If you have set a power-on password, a password
prompt appears. You must enter your password before the first screen of
your operating system or application program will appear. (For more
information on using passwords, see “Power-On Password” on page 32.)

If Power On Status is Enabled and POST detects a problem, you will hear
multiple beeps or no beep. In most cases, an error code appears in the top
left corner of the screen, and in some cases a description of the error is
