xii Using Your Personal Computer
Chapter 1. Your IBM Personal Computer
Thank you for selecting an IBM Personal Computer. Your PC incorporates many of
the latest advances in personal computer technology and is easy to expand and
upgrade as your needs change. With its enhanced video and system-management
capabilities, your computer is particularly suited for your corporate intranet
environment.

Identifying Your Computer
In most instances, the best way to identify your computer is by the machine
type/model number. The model/type number indicates the various features of the
computer, such as the type of microprocessor or the number of bays. You can find
this number on the small label on the front of your computer. An example of a
machine type/model number is 6282-54A.
You also need to know whether the computer is a desktop or tower. The desktop
model can be set on its side in a floor stand, but the orientation of the drives will be
vertical in that position, rather than horizontal. Towers and desktops used in their
normal orientations have horizontal drive bays.
Throughout this book, your computer is identified as either a desktop model or a
tower model. These naming conventions are used only where it is appropriate.
Instructions without these naming conventions apply to both computer models.
Desktop Model
The desktop model comes with four bays and four expansion slots. This computer
has a hard disk drive in bay 3 and a diskette drive in bay 4. If your computer has a
CD-ROM drive, it is installed in bay 1. Bay two can accept a hard disk drive which
does not have accessible media.
2 Using Your Personal Computer
Tower Model
The tower model comes with six bays and six expansion slots. This computer has a
hard disk drive in bay 6 and a diskette drive in bay 4. If your computer has a
CD-ROM drive, it is installed in bay 1. Bays two, three and five can accept hard
disk drives which do not have accessible media.
Chapter 1. Your IBM Personal Computer 3
What Your IBM Personal Computer Offers
This section describes many of the features of your computer.
Microprocessor
At the core of your PC is an Intel Pentium II processor. With its advanced
performance features, this MMX microprocessor supplies the speed and power you
need to take advantage of even the most complex programs. In addition, the
microprocessor incorporates new multimedia extensions into the Intel architecture,
which improves the performance of multimedia and communications applications
by accelerating calculations commonly performed for audio, video, speech synthesis
and recognition, 2D and 3D graphics, and data communications.
System Memory
Your computer comes standard with non-parity or ECC (error correcting code)
SDRAM (synchronous dynamic random access memory).
L2 Cache
L2 cache memory, which helps speed the exchange of information between the
microprocessor and system memory, is integrated on the Pentium II processor in
most models.
ISA Bus
Your PC has an ISA (industry standard architecture) bus, which is one of the most
widely used and successful I/O (input/output) buses available. The ISA bus is
popular because so many adapters and devices have been designed and marketed
for it.
PCI Bus
Your computer also has a PCI (peripheral component interconnect) bus. PCI is one
of the advanced I/O bus standards recently developed by the computer industry to
keep up with performance improvements of microprocessor buses and advanced
peripheral devices. The PCI bus adds to the capability of the ISA bus, speeding up
the exchange of information among the microprocessor and peripheral devices
within your computer system. This improves the overall performance of your
computer, including the hard disk drive.
4 Using Your Personal Computer
AGP Bus
Your computer also has an integrated AGP Cirrus 5465 3-D SVGA (super video
graphics array) bus. AGP is a state-of-the-art enhanced performance video bus for
the integrated video controller, which provides a PC-like interface with performance
extensions added specifically for video functions.
Expansion with Adapters
By installing optional adapters, you can expand the capabilities of your computer
and take advantage of a variety of peripheral devices and applications. Your
computer has a riser card for connecting adapters to the ISA or PCI bus. Examples
of adapters that can be added to your computer include graphics, SCSI (small
computer system interface), and NIC (network interface controller) adapters.
High-Capacity Hard Disk Drives
Some PC models come with a hard disk drive that has an enhanced integrated drive
electronics (EIDE) bus-master interface. The EIDE drive plugs into one of two EIDE
connectors located on the riser card in your computer. You can connect an
additional hard disk drive to the ribbon cable already attached to the riser card, or
you can purchase another cable and connect up to two hard disk drives or other
IDE or EIDE devices to the second connector on the riser card.
Notes:
1. In the desktop model, a maximum of three internal IDE or EIDE devices can be
installed—limited by the number of available bays.
2. For models with an IBM factory-installed CD-ROM, two ribbon cables (for
connecting IDE or EIDE devices) are shipped with your computer.
CD-ROM Drive
A CD-ROM drive is installed in some PC models. CD-ROM (compact disc
read-only memory) technology offers quick access to enormous amounts of
information. A compact disc can store more than 650 MB of data, such as the large
files needed for audio, still and full-motion video, and still and animated graphics.
A CD-ROM drive can play back or read from a CD, but it cannot write information
on it.
ECP/EPP Parallel Port
Your PC has one 25-pin parallel port. The parallel port is most often used to
communicate with a parallel printer, but it can also be used with other parallel
Chapter 1. Your IBM Personal Computer 5
devices. To minimize electromagnetic interference (EMI), use braid-shielded cables
with metal ends when connecting a device to this port.
The parallel port can operate in several different modes. The default mode for your
computer is SPP (standard parallel port). However, your computer also supports
the ECP/EPP (extended capabilities port/enhanced parallel port) mode. ECP/EPP
has two advantages over SPP. When your computer is in ECP/EPP mode, you can
print documents faster than when the computer is in SPP mode, and you can attach
devices other than printers, such as communication and storage devices, to the
parallel port. You can set modes of operation for the parallel port using the
Configuration/Setup Utility Program.
Serial Ports
Your computer has two standard 9-pin, 16550-UART serial ports that can be used to
communicate with devices such as modems, plotters, and printers. To minimize
electromagnetic interference (EMI), use braid-shielded cables with metal ends when
connecting devices to these ports.
Universal Serial Bus Ports
The universal serial bus (USB) interface is a new, emerging technology being
developed to add more diversity and capabilities to personal computers. IBM has
provided two, 4-pin USB connectors in your computer as a standard feature so you
can be ready to take advantage of new USB devices as they become available.
Using this new technology, you will be able to plug many different types of
optional, USB-compatible devices into the USB ports on your computer. Because
USB incorporates Plug and Play technology, you can install and remove devices
easily without turning off your computer or opening the cover. Once installed, the
devices configure automatically.
In addition, an option called a hub can be connected to a USB port on your
computer, which enables you to plug in more than one device at a time. A hub
converts a single USB connector into multiple ports where USB devices can be
attached.
For more information, see the USB Web site (http://www.usb.org). For USB
drivers, see the Microsoft Web site (http://www.microsoft.com/support).

can slide the system board in and out of the computer frame.
Support for Plug and Play technology is built into the system board of your PC.
This feature makes adding options easier. When you add an adapter that is Plug
and Play-compatible, the adapter is configured automatically. In most cases, no
switches or jumpers have to be set on the adapter.
If you have a problem with your PC, IBM provides an easy-to-use diagnostic
program (PC Doctor) that you can run to help determine if a hardware component
is causing the problem. You can create a startable PC Doctor diskette for your
computer from the download or the Ready-to-Configure Utility Program CD. In
addition, operating system-specific diagnostic programs (and PC Doctor) are
included on the Ready-to-Configure Utility Program CD for your computer.

Chapter 2. 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, here are a few guidelines
to help you find a position that suits you best.
Sitting in the same position for a long time causes fatigue. A good chair can make a
big difference. 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.
Adjust the monitor so 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.

Viewing Distance
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, when 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, an antiglare
filter placed over the screen might be helpful. 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. When 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 get kicked accidentally.
For more information about power cords, see “Power Cord Notice” on page 123.

Starting Your Computer
What you see and hear when you start up your computer depends upon 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: There are other selections that might also change what is displayed.
The following briefly describes what you see in the default mode when you turn on
your computer:
The IBM logo appears
Press F1 for Configuration/Setup prompt appears
– If any errors were detected during POST, they are displayed.
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. (Refer to “System Security” on page 45 for
instructions on setting and using passwords.) Type your password at the
prompt and press Enter.
The first screen of your operating system or application program appears.
If Power On Status is [Enabled], and 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
28 Using Your Personal Computer
descriptions.) Write down all error code numbers and descriptions. For
information on what caused an error message to appear and what action to take,
refer to “Solving POST Error Message Problems” on page 66 and “POST Message
Charts” on page 69.
If Power On Self Test is [Enhanced], information about memory configuration and
test results are shown in the upper left corner. Prompts for running a fast POST or
accessing the Configuration/Setup Utility Program appear in the lower-left corner of
the screen.
Using a Mouse
A mouse is a device that you use to point to and select objects on the monitor screen.
It connects to your computer by a cable. Some mouse devices are designed for the
round mouse connector on the back of your PC; other mouse devices are designed
for the D-shaped serial connector. You can use either type of mouse, if the correct
software (device driver) is installed.
With a mouse, you can move the pointer on the monitor screen. If you have never
used a mouse before, it might feel a bit awkward at first. However, with a little
practice, the mouse movements will seem natural.
Place the mouse beside the keyboard on a flat surface or mouse pad. (A mouse pad
is a flat, smooth, foam-rubber pad available at most computer stores.) The mouse
has a ball on the bottom, so working on a flat, smooth surface is important. You
can use your right or left hand to control the mouse.
Notice that the mouse has two buttons on the top (some mice have more buttons).
Rest your hand comfortably on the mouse with your index finger on the left button
(if you are using your right hand). Some programs and operating systems provide
an option to set up the mouse for left-hand use. When a mouse is set up for
left-hand use, the button functions are reversed.
Use the left button to select and open objects with the mouse. Some programs also
use the right button. The use of the right mouse button varies.
To use the mouse, slide it from side to side and forward and backward on a flat
surface. The pointer on the monitor screen moves as you move the mouse. When
you see an item that you want to select on the screen, you simply move the pointer
to that item (this is called pointing). Then you press and release the left button on
the mouse (this is called clicking).
To learn how to use the mouse with the software in your computer, see the
documentation accompanying the software.
Chapter 3. Operating Your Personal Computer 29
Some programs support only one mouse button, others support two, and some
support three. Despite the differences, some terms are fairly standard throughout
the industry.
Point Move the mouse so the pointer is on the object you want.
Click Press and release the mouse button once.
Double-click Rapidly press and release the mouse button twice.
Drag Point to an object, press the mouse button, and hold it down as you
move the mouse to relocate the object.
Drop After dragging an object to a new location, release the mouse button.
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 Video Features
Your computer has an integrated AGP Cirrus 5465 3-D SVGA (super video graphics
array) controller. 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
depth defined by a video standard for displaying text or graphics. (For further
information on video modes, refer to Understanding Your Personal Computer.)
SVGA provides higher-resolution graphics, faster refresh rates, and more colors than
previous video standards, such as video graphics array (VGA). At the same time,
SVGA supports all standard VGA modes.
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. Instructions for doing this are
included in a README file that is provided on the Ready-to-Configure Utility
Program CD for your computer.
Refer to your operating-system documentation for further information on monitor
settings.
30 Using Your Personal Computer
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
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.
Video Device Drivers
To take full advantage of the video controller 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.
The video device drivers are provided on the Ready-to-ConfigureUtility Program CD
for your computer. Instructions for installing the device drivers are provided on the
Ready-to-Configure Utility Program CD in the README file that corresponds to your
operating system. IBM also maintains the latest versions of video device drivers for
all IBM-manufactured computers on the World Wide Web.
If your computer has IBM-preinstalled software, video device drivers have already
been installed on the hard disk in your PC. However, the device driver installation
instructions in the README file will be helpful 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.
Video Controller
The video controller in your computer supports the use of AGP, which can speed
up the process of displaying video graphics. This feature for the video controller is
activated by the video device drivers when the video interrupt feature is set to
Enabled (the default) in the Configuration/Setup Utility program.
Chapter 3. Operating Your Personal Computer 31
If you leave the bus master activated, the video device drivers and the video
controller operate at a faster speed. When the video controller needs information
from system memory, the video controller can become the bus master and fetch the
information directly from memory. This means the video controller will not have to
wait for the microprocessor to read the information and write it to video memory.
You can accomplish this by changing the video interrupt setting from Enabled to
Disabled, using the Configuration/Setup Utility program (described on page 39).
Using System-Management Features
This section is intended primarily for network administrators. It describes features
of your computer that make it possible for a network administrator to remotely
manage and control your PC when it is linked to a network.
The BIOS (basic input output system) of your computer supports an interface called
DMI (Desktop Management Interface). DMI is software used to gather information
about the hardware and software in your computer so that network administrators
can remotely monitor and control your PC. DMI can be used to remotely track
many types of information about networked PCs, including serial numbers, memory
attributes, product-specific characteristics of installed peripherals, and operating
system configuration information. This information can be accessed using a DMI
browser. DMI browsers are provided by all major operating systems and all major
LAN management packages (including TME 10 NetFinity, Intel LAN Desk, and
Microsoft SMS).
The Wake on LAN feature can be used by a network administrator to turn on your
PC from a management console. When Wake on LAN is used in conjunction with
network-management software, such as TME 10 NetFinity Version 4 (provided on
the Ready-to-Configure Utility Program CD for your computer), many types of
functions, such as data transfers, software updates, and POST and BIOS updates can
be performed remotely on your PC and other computers enabled for Wake on LAN
that are linked to your network. This updating can be done after hours and on
weekends, which saves time and increases productivity. Users are not interrupted
during normal working hours and LAN traffic is kept to a minimum.
Other features such as remote program load (RPL) and dynamic host configuration
protocol (DHCP) also allow a network administrator to remotely control your
computer. If you use remote program load in conjunction with LANClient Control
Manager software, you can use a feature called Hybrid RPL. Using LANClient
Control Manager, you set up your computer by installing hybrid images (or files) on
the hard disk drive. 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. This bootstrap program is
32 Using Your Personal Computer
small and helps prevent network congestion. Working off the hybrid images, the
bootstrap program initiates the startup process from the hard disk drive of your
computer. An advantage to Hybrid RPL is that the network load associated with
standard RPL is avoided.
System Programs
System programs are the basic layer of software built into every IBM PC. 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 every time you turn on your PC. The BIOS is a layer of software
that translates instructions from other layers of software into instructions that the
computer hardware can understand. The Configuration/Setup Utility Program
enables you to view and change the configuration and setup of your computer.
In the past, the system programs were contained in a read-only memory (ROM)
module on the system board. If you wanted to update POST routines, BIOS
instructions, and the Configuration/Setup Utility Program, you had to disassemble
the computer and replace modules, or you had to replace the system board. Now,
the system programs are stored in an EEPROM (electrically erasable programmable
read-only memory) module, which is also referred to as a flash memory. The contents
can be easily updated with an update (flash) diskette. The process of updating the
system programs EEPROM is often referred to as flashing the BIOS.
Updating the System BIOS
As part of the continuing work to improve quality, IBM might make changes and
enhancements to the system programs. When updates are released, they will be
available on the World Wide Web (http://www.pc.ibm.com/desktop/) or through
the PC Company Bulletin Board Service (see “Using Electronic Support Services” on
page 103) in files that can be downloaded onto a diskette. Updates on the Web site
or BBS will have the file name NZKTnnA.EXE, where nn is a release number.
Instructions for using the system programs updates will be available in a README
file included in the downloaded files. When updating system programs with a flash
diskette, note the following:
If you have set an administrator password, your computer will halt and request the
administrator password. The update process will not begin until you enter the
password. If you have set an administrator password, the system programs update
will run only if you first perform a cold startup (the computer is turned off and
then turned on).
Chapter 3. Operating Your Personal Computer 33
If your computer is connected to a network, the system programs also can be
updated remotely, using network-management software, such as IBM LANClient

Using a CD-ROM Drive
Some PC models have a preinstalled CD-ROM drive. CD-ROM (compact disc
read-only memory) technology offers quick access to enormous amounts of
information. A compact disc can store more than 650 MB of data, such as the large
files needed for audio, still and full-motion video, and still and animated graphics.
A CD-ROM drive can play back or read from a CD, but it cannot write information
to it. CD-ROM drives use industry-standard, 12 cm (4.75-inch) CDs.
Follow these guidelines when using a CD-ROM drive:
Do not place the drive where there is:
– High temperature
– High humidity
– Excessive dust
– Excessive vibration or sudden shock
– An inclined surface
– Direct sunlight
Do not insert any object other than a CD into the drive.
Before moving the computer, remove the CD from the drive.
Handling a CD
When handling a CD, follow these guidelines:
Hold the CD by its edges. Do not touch the surface.
To remove dust or fingerprints, wipe the CD from the center to the outside.
Wiping the CD in a circular direction might cause loss of data.
Do not write or stick paper on the CD.
Do not scratch or mark the CD.
Do not place or store the CD in direct sunlight.
Do not use benzene, thinners, or other cleaners to clean the CD.
Do not drop or bend the CD.

Power-On and Administrator Passwords
Important
Keep a record of your administrator password in a secure place. If you lose or
forget the administrator password, you will not be able to access the
Configuration/Setup Utility program, and you will not be able to erase and reset
an administrator password. If you lose or forget your password, you must
remove the computer cover and move a jumper on the system board. (Refer to
“Erasing a Lost or Forgotten Administrator Password” on page 51 for further
information.)
These password features help prevent unauthorized persons from gaining access to
the information stored in your computer. Other password security features might
be available through your operating system or network.
Power-On Password
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 computer's 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.
Note: If Update POST/BIOS from network is enabled, you cannot
select On. In this case you should select Dual. If it is set to On
46 Using Your Personal Computer
when Update POST/BIOS from network is enabled, it will
automatically be reset to Dual.
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 text box.
Important Information for Mouse Users
This information applies only to those who have a mouse connected
to the mouse port; a serial mouse is not affected by the password
prompt Off mode.
The password prompt Off mode prevents the computer from
detecting that a mouse is attached. Because the mouse device driver
will not be loaded automatically through the CONFIG.SYS or
AUTOEXEC.BAT files in this mode, an error message that the mouse
port is disabled will appear and the computer will halt. To enable
the operating system to load without displaying the error message,
read the information below that applies to your operating system.
If you are using OS/2, do one of the following before enabling
password prompt Off mode:
Set the CONFIG.SYS file so the operating system does not stop on
a device-driver error. To do this, put the command
"PAUSEONERROR=NO" near the top of the CONFIG.SYS file.
or
Remove the mouse driver statement from the CONFIG.SYS file.
If you are using Windows NT or Windows 95, do the following:
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. Then use the keyboard to put
a check mark in the Do not display this message in the future
check box.
Once the operating system starts in password prompt Off mode, the
keyboard will remain locked. If you have a mouse connected to the
mouse port, it also will remain locked.
Although you are not prompted to type a password in this mode, you
can type either your power-on or administrator password anytime after
POST has completed, even after the operating system has loaded. If you
Chapter 4. Configuring Your Computer 47
type a password, the keyboard will unlock, but the mouse connected to
the mouse port will remain disabled.
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 in this mode
when power is restored, without operator intervention.
Dual In the password prompt Dual mode, the startup behavior of the
computer depends on whether the computer is started from the
computer power switch or by an unattended method, such as a modem
or timer.
If you start the computer by using the power switch, the computer
operates the same as it does in password prompt On mode. Refer to
page 46 for further information.
If the computer is started by an unattended method, such as remotely
over a LAN, the computer operates the same as it does in password
prompt Off mode. Refer to page 47 for further information.
If both a power-on and administrator password are set, you can type either
password at the password prompt that appears as you start your computer. However,
if you want to change any settings in the Configuration/Setup Utility Program, you
must type your administrator password at the password prompt that appears when
you try to access the Configuration/Setup Utility Program. If you type your power-on
password at this prompt, you will be able to view limited information in the
Configuration/Setup Utility Program, but you will not be able to change any
settings.
The password does not appear on the screen as you type it. If you type the wrong
password, you receive a screen message telling you so. If you type the wrong
password three times, you must turn off the computer and start again. When you
type the correct password, the keyboard and mouse will unlock, and the computer
will begin normal operation.
Setting and Changing a Power-On Password
Use the Configuration/Setup Utility Program to set or change a power-on
password. You can use any combination of up to seven characters (A–Z, a–z, and

58 Using Your Personal Computer
Chapter 5. Taking Care of Your Computer
This chapter 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 off the computer and monitor power switches 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.
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.
Copyright IBM Corp. 1998 59
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. In addition, an anti-static cleaner can be
used to slow the buildup of dust on the screen surface.
Mouse
If the pointer on the screen does not move smoothly with the mouse, you might
need to clean the 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.
60 Using Your Personal Computer
Replacing the Battery
Your computer has a special type of memory that maintains the date, time, and the
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 of this publication and Installing
Options in Your Personal Computer for information about replacing 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.
Moving Your Computer
Important
Do not move the computer while it is on. Sudden movements, such as bumps,
jerks, and drops, can cause the read/write head of the hard disk drive to bounce
against the surface of the disk itself. This can cause loss of data and a variety of
hard disk errors. Always turn off the computer before you move it. When the
computer is off, the read/write head automatically parks itself over a nondata
area of the hard disk. This process can help to prevent damage to the hard disk.
CAUTION:
Do not risk injury by moving or lifting the computer by yourself. Ask another
person to help you.
If your computer has a hard disk drive, take the following precautions:
1. Back up all files and data from the hard disk.
Operating systems can vary in the way they perform backup procedures. Some
operating systems save only data files, while others make copies of application
Chapter 5. Taking Care of Your Computer 61
program files and data files. Refer to your operating-system documentation for
information about software backup.
2. Remove all media (diskettes, compact discs, tapes, and so on) from the drives.
3. Turn off the computer and all attached devices.
4. Unplug the power cords from electrical outlets.
5. Note where you have attached your cables to the rear of the computer; then
remove them.
6. If you saved the original shipping cartons and packing materials, use them to
pack the units. If you are using different cartons, cushion the units to avoid any
damage.
62 Using Your Personal Computer
Chapter 6. Solving Problems
This chapter presents an overview of diagnostic tools 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
terminate-and-stay-resident (TSR) programs.
Important
If you have just added new software or a new computer option and your
computer is not working, do the following before using the other information in
the chapter:
Remove the software or device you just added.
Run the diagnostic programs to determine if your computer is running
correctly. (See “Diagnostic Programs” on page 97 for information about
diagnostic programs provided with your computer.)
Reinstall the new software or new device.
Using Diagnostic Tools
Computer problems can be caused by hardware, software, or user error (for
example, pressing the wrong key). Using the diagnostic aids discussed in this
chapter, you might be able to 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 “Diagnostic
Programs” on page 97 for a description of these programs).
If the hardware checks out OK, 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, refer to About Your Software
and the operating-system documentation that comes with your computer. If you
have installed software applications yourself, consult the documentation that comes
with the software.
Copyright IBM Corp. 1998 63
The following tools are available to diagnose hardware-related problems:
Power-on self-test (POST)
Error messages
POST message charts
Troubleshooting charts
Diagnostic programs
Note: In addition to the preceding tools, if you have access to the World Wide
Web, you can also view or download the latest problem-solving tips from
the http://www.us.pc.ibm.com/desktop/ Web site.
Descriptions of the diagnostic tools follow.
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).
Note
If your computer starts but does not boot when you press the power switch, do
the following:
Make sure all cables are securely connected to the correct locations.
Check to see if the voltage-selection switch is set to the correct position for
your country.
For additional information, see Setting Up Your Personal Computer.
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 the presence of diskette drives, hard disk drives, and the CD-ROM
drive (if installed)
If Power On Self Test is [Enhanced], information about memory configuration and
test results are shown in the upper left corner. Options for running a quick POST
64 Using Your Personal Computer
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 further information on using passwords, refer to “System
Security” on page 45.)
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 displayed beside the code.
(Note that the screen will sometimes display multiple error codes and descriptions.)
For more information about what caused an error message to appear and what
action to take, refer to “Solving POST Error Message Problems” on page 66 and
“POST Message Charts” on page 69.
If you hear no beep at all during POST, refer to “Troubleshooting Charts” on
page 87. You might need to have your computer serviced.
Error Messages
Error messages that appear on the screen might be text, numeric, or both. There are
several types of error messages:
POST error messages
Messages that appear when POST finds problems with the hardware during
startup or when a change in the hardware configuration is found. POST error
messages are 3-, 4-, 5-, 8-, or 12-character alphanumeric messages and include
brief explanations (except I999XXXX errors).
For more information about what caused an error message to appear and what
action to take, refer to “Solving POST Error Message Problems” on page 66 and
“POST Message Charts” on page 69.
Software-generated error messages
Messages that appear if a problem or conflict is detected by the application
program, the operating system, or both. Error messages for operating-system
and other software problems are generally text messages, but they also can be
Chapter 6. Solving Problems 65
numeric messages. For information about these software error messages, refer
to the information that comes with the operating system or application program.
Diagnostic error messages
Messages that appear if a hardware problem is detected by a diagnostic test
program. The messages present text information that can be used to identify a
failing part.
Solving POST Error Message Problems: If you receive an error message
during the power-on-self-test (POST), completing the steps outlined in this section
might enable you to resolve the problem.
Note
If you have just added, removed, or changed the location of a device and you
receive an error message, follow the procedure described in the Important text
box on page 40. If the procedure on page 40 does not eliminate the error
message, then proceed with the following instructions.
1. Write down all error code numbers and descriptions that appear on the screen
as you start your computer. (Note that a single problem can cause several error
messages to appear. When you correct the cause of the first error message, the
other error messages probably will not appear on the screen the next time you
turn on your computer.)
2. If you have set a power-on password, a password prompt appears. If you have
set both power-on and administrator passwords, you can type either password
at the password prompt. However, if you think you might need to change any
settings in the Configuration/Setup Utility Program, type your administrator
password at the password prompt. If you type your power-on password, you
will be able to view error codes and error code descriptions displayed on the
POST Startup Errors screen, and you will also be able to view limited
information in the Configuration/Setup Utility Program. However, you will not
be able to change any settings.
3. In the case of most errors, the Configuration/Setup Utility Program starts
automatically so that you can attempt to identify and correct the problem.
When the Configuration/Setup Utility Program starts, a screen labeled POST
Startup Errors appears. (Note that the POST Startup Errors screen does not
appear immediately. You must wait approximately one minute.) If the POST
Startup Errors screen does not appear, proceed to step 6.
4. At the POST Startup Errors screen, select Continue if you want to access the
Configuration/Setup Utility Program menu. Select Exit Setup if you want to
exit the Configuration/Setup Utility Program. (See the following Important text
66 Using Your Personal Computer
box for information on exiting the Configuration/Setup Utility Program without
making any changes to current settings.) To select an item, press Up Arrow (↑)
or Down Arrow (↓) to highlight the item, and then press Enter.
Important
If you exit from the Configuration/Setup Utility Program without selecting
Save Settings, your operating system will not start, but the computer will
automatically restart. When the computer restarts, you will get a POST error
message, and then the Configuration/Setup Utility Program will again start
automatically.
If you select Save Settings and then exit the Configuration/Setup Utility
Program, your system will save all settings as they currently appear in the
Configuration/Setup Utility Program and your operating system will start
(unless there is an unresolved problem with an IDE device).
5. If you selected Continue in step 4 on page 66, the Configuration/Setup Utility
Program menu appears on the screen. You will see a pointer next to any menu
items that are malfunctioning or that have been changed since the last time you
turned on your computer. If you did not knowingly make a change to a
flagged menu item, there is likely a malfunction in that item. If you made a
change, continue here. If you did not make a change, go to the Important text
box on page 67.
To use the Configuration/Setup Utility Program, do the following:
a. Select the menu item that is flagged (or that you wish to view) by pressing
Up Arrow (↑) or Down Arrow (↓), and then press Enter.
b. A new menu specific to the item that you selected appears. Press Left
Arrow (←) or Right Arrow (→) to toggle between choices for a menu item.
(Note that each menu item has a Help screen. To view the Help screen,
select the menu item, and then press F1.)
c. When you have finished viewing and changing settings, press Esc to return
to the Configuration/Setup Utility Program menu.
d. Before you exit from the program, select Save Settings.
e. To exit from the Configuration/Setup Utility Program, press Esc and follow
the instructions on the screen. When you exit from the Configuration/Setup
