overview

Thank you for selecting an IBM PC computer. Your computer incorporates
many of the latest advances in computer technology and can be upgraded
as your needs change.

This section provides an overview of the computer features, preinstalled
software, and specifications.

Identifying your computer

In most instances, the best way to identify your computer is by the machine
type/model number. The machine type/model number indicates the
various features of the computer, such as the type of microprocessor and
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
6564-110.

The information in this guide is for both PC 300GL desktop and tower and
PC300PL desktop models, and the different machine types of these models.
When it is necessary to distinguish between models and machine types, you
will be given a reference to the specific model and type number (for
example, PC 300PL 6565). When the model or machine type is not
specified, the information applies to all computer models and machine
types.

Chapter 2. Setting up your computer

This section provides information for connecting cables to your computer
and turning on the power.

Before you begin

Read “Safety information” on page ix before setting up your computer.

You will need the following:
 Computer

 Computer power cord
 Keyboard
 Mouse

 Monitor (sold separately with signal cable and power cord)

If you are missing an item, contact your place of purchase.

Selecting a location for your computer

Make sure you have an adequate number of properly grounded electrical
outlets for the computer, monitor, and any other devices. Select a location
for the computer where it will remain dry. Leave about 50 mm (2 in.) of
space around the computer for proper air circulation.

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

 Copyright IBM Corp. 2000 9

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 that you can view it without having to
twist your body.

Note: If your monitor weighs more than 100 pounds (45.4 Kg), do not

place it on the top of a desktop model computer.

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.

10 PC 300PL and PC 300GL User Guide

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 161.

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:

Note: The following screens or messages might display only for a very

short period.

1. The IBM logo appears.

2. The following messages appear:

Press F12 to boot from the network
Press F1 for Configuration/Setup

3. If any errors were detected during POST, messages about them are
displayed.

4. 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.

5. If the system hardware configuration has changed or an error is
detected, the Configuration/Setup Utility program menu might be
displayed when you press Enter.

For more information, see “Power-on self-test (POST)” on page 100.

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. The
screen will sometimes display multiple error codes and descriptions. Write
down all error code numbers and descriptions.

Chapter 3. Operating and caring for your computer 23

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. This prevents the loss of unsaved
data or damage to your software programs. See your operating system
documentation for instructions.

Using diskettes

You can use 3.5-inch diskettes in the diskette drive of your computer. The
information that follows will help you use 3.5-inch diskettes.

Handling and storing diskettes

Inside the protective diskette case is a flexible disk with a
magnetic-sensitive coating. This disk can be damaged by heat, dust, a
magnetic field, or even a fingerprint. Use the following guidelines when
handling and storing diskettes:

 Data is stored on the magnetic surface of the diskette. This surface is

protected by a plastic cover. If the cover is damaged, do not use the
diskette. A damaged diskette might damage the diskette drive.

 A protective slide on the top of a 3.5-inch diskette covers part of the

magnetic surface. The diskette drive moves this slide to read data from
or write data to the diskette. Do not move this slide because
fingerprints and dust can cause loss of data.

 Never touch the magnetic disk itself.
 Keep diskettes away from magnets or devices that create a strong

magnetic field, such as electric motors and generators. Diskettes are
sensitive to magnets found in television sets, telephones, stereo
speakers, and other such items. A magnetic field can erase the data on
your diskettes. Do not set diskettes on the monitor or use magnets to
attach notes to your computer.

 Do not store diskettes at high temperatures, low temperatures, or in

direct sunlight. Temperatures ranging from 4° to 53°C (39° to 127°F)
are acceptable for 3.5-inch diskettes. Keep diskettes away from heat.
The plastic outer covering might warp, damaging the diskette.

24 PC 300PL and PC 300GL User Guide

Inserting and removing diskettes

To insert a 3.5-inch diskette, hold the diskette with the label facing up and
insert the end with the protective slide first. Push the diskette into the
diskette drive until the diskette clicks into place.

To remove the diskette, press the eject button and slide the diskette out of
the drive. Do not remove the diskette while the in-use light is on.

Write-protecting diskettes

It is possible to accidentally format a diskette or unintentionally write data
to it. Important information can be written over or lost. For this reason, it
is a good idea to write-protect important diskettes. You can read data from
a write-protected diskette, but you cannot erase or change the data.

Most 3.5-inch diskettes have a write-protect switch that can be used to
prevent data from being written to or erased from the diskette. If a 3.5-inch
diskette does not have a write-protect switch, it is permanently
write-protected.

The write-protect switch is located on the back of 3.5-inch diskettes.

 To allow writing to the diskette, slide the switch so the write-protect

window is covered.

 To prevent writing to the diskette, slide the switch so the write-protect

window is open.

Your computer also has a switch on the system board that when set to ON,
prevents writing to a diskette regardless of the position of the write-protect
switch on the diskette. See “Setting the diskette write-protect switch” on
page 78 for instructions for setting diskette write-protect on the system
board.

Chapter 3. Operating and caring for your computer 25

Using CD-ROM, CD-RW, or DVD drives

Some models have preinstalled CD-ROM, CD-RW (CD-Rewritable), or DVD
drives. CD-ROM drives can play back or read a CD, but cannot write
information to it. CD-RW drives use prerecorded or recordable CDs. DVD
drives can play back CDs, CD-RWs, and DVD discs. DVD technology
allows for more data storage over CD-ROM and CD-RW, therefore, DVD
drives use DVD recording media. CD-ROM and CD-RW drives use
industry standard, 12 cm (4.75-inch) CDs.

Follow these guidelines when using a CD-ROM, CD-RW, or DVD 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

 Use only prerecorded CDs in CD-ROM drives. Use prerecorded CDs

and CD-RWs in CD-RW drives. Use DVDs, CD-RWs, and prerecorded
CDs in DVD drives. DVDs and CD-RWs will not work in CD-ROM
drives. Do not insert any object other than a compact disc or DVD into
a CD or DVD drive.

 Before moving the computer, remove the CD from the drive.

Handling CDs,CD-RW, and DVDs

When handling a CD, CD-RW, or DVD, follow these guidelines:

 Hold the disk by its edges. Do not touch the surface of the side that is

not labeled.

 To remove dust or fingerprints, wipe the disk with a clean, soft cloth

from the center to the outside. Wiping the disk in a circular direction
might cause loss of data.

 Do not write or stick paper on the disk.
 Do not scratch or mark the disk.
 Do not place or store the disk in direct sunlight.
 Do not use benzene, thinners, or other cleaners to clean the disk.
 Do not drop or bend the disk.

26 PC 300PL and PC 300GL User Guide

Loading a CD, CD-RW, or DVD

To load a CD, CD-RW, or DVD into the drive:

1. Press the eject/load button. The tray slides out of the drive. (Do not
manually force the tray open.)

2. Place the disk in the tray with the label facing up.

3. Close the tray by pressing the eject/load button or by gently pushing
the tray forward. When the tray is closed, the indicator light on the
front of the drive will activate to indicate that the drive is in use.

4. To eject the disk, press the eject/load button. When the tray slides out,
carefully remove the disk.

5. Close the tray by pressing the eject/load button or by gently pushing
the tray forward.

Note: If the tray does not slide out of the drive when you press the

eject/load button, insert the pointed end of a large paper clip into
the emergency-eject hole located on the front of the CD-ROM drive.

Important

If you set up your computer so that the CD-ROM drive tray is in a
vertical position, make sure that the CD retainer devices on the tray are
positioned to hold the CD in place after you close the tray. (Several
different retainer device designs are found on CD-ROM drives. For
some, you will need to rotate or extend two or more tabs or clips.
Other designs use a wire bail that you need to reposition in the drive so
that it will hold the CD in place.)

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).

IBM Universal Manageability tools streamline and automate PC systems
management and support tasks, such as computer equipment use and
tracking. These leading-edge PC tools are available for IBM PCs at no
additional charge, helping to reduce total cost of ownership of your
networked PCs and allowing you to focus vital company resources on
essential business activities. For more information go to
http://www.ibm.com/pc/us/software/sysmgmt on the World Wide Web.

Chapter 3. Operating and caring for your computer 27

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 Manager (available on
the World Wide Web) 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.

Alert on LAN

Your computer supports Alert on LAN technology. Alert on LAN
technology provides notification of changes in the computer system even if
the computer is turned off. Working with Desktop Management Interface
(DMI) and Wake on LAN technologies, Alert on LAN helps to manage and
monitor the hardware and software features of your computer.

Alert on LAN generates notifications when POST fails during a Wake on
LAN attempt, the computer is disconnected from the network, or when the
computer is unplugged from the electrical outlet. Alert on LAN can be
integrated with network-management software such as LANClient Control
Manager and IBM Netfinity Manager.

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) or Dynamic Host Configuration
Protocol (DHCP) to control your computer. If you use RPL in conjunction
with software such as IBM 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.
Hybrid RPL avoids the network traffic associated with a standard RPL.

28 PC 300PL and PC 300GL User Guide

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 51 for
configuration information.

LANClient Control Manager (LCCM)

LANClient Control Manager (LCCM) is a graphical, server-based program
that aids in system deployment by enabling unattended system installation
of operating systems, complete software images, device drivers, and BIOS
updates. When used with Wake on LAN, LCCM can remotely start your
computer from an off state, which means all this can be done while the
system is not being used. When you purchase an IBM PC, LCCM is
available for downloading at no additional charge (Internet access fees

Additional security features of the PC 300PL 6565

If you have a PC 300PL 6565, your computer contains additional security
features. Some of these features include Enhanced Security, a
chassis-intrusion detector, a cover lock and keys for the computer chassis,
and IBM security solutions to protect your electronic business transactions.

Enhanced Security

Enhanced Security is provided in the PC 300PL 6565 for additional
protection of your administrator password and startup sequence. If you
enable Enhanced Security, your administrator password and startup
sequence are stored in a highly-protected, nonvolatile, security EEPROM
module that is separate from CMOS memory and the EEPROM module that
stores system programs. When your administrator password and security
sequence are protected by Enhanced Security, they remain intact even if the
battery in your computer expires or is removed by someone. For more
information, see “Using Enhanced Security” on page 48.

Cover lock

A cover lock built into the chassis of the PC 300PL 6565 prevents the cover
from being easily removed. The cover lock comes with two identical keys.

Chapter 3. Operating and caring for your computer 31

Important

A tag attached to the keys lists the serial number of the keys and the
address of the key manufacturer. Record the key code number, key
manufacturer address, and phone number in the space provided in
Appendix B, “Computer records” on page 139.

Locksmiths are not authorized to duplicate the cover lock keys. If you
need to order replacement keys, you will need this important
information.

Chassis-intrusion detector

A chassis-intrusion detector inside the PC 300PL 6565 alerts the system
administrator if the computer cover has been removed. This detector is
enabled after you set an administrator password in the Configuration/Setup
Utility program.

After the password is set, if the computer cover is removed, a POST error
message (176) displays on the computer screen the next time the computer
is turned on. If the chassis-intrusion detector detects that the cover has
been removed, then before you can start up the computer you must first
enter the correct administrator password. For information on setting
passwords, see “Using an administrator password” on page 45.

Asset ID capability

Asset ID capability is installed in the PC 300PL 6565.

With Asset ID, you can use a radio-frequency device, such as a portable
scanner, and the antenna attached to the front of your computer to access
information about your computer. An EEPROM module on the system
board stores the information about your computer, including configuration
data and the serial numbers of key components. It also includes blank
fields that you can use to record specific information about your computer,
if your choose. (Asset ID is intended for use only with radio frequency
equipment that meets ANSI/IEEE C95.1 1991 RF Radiation Limits.)

IBM security solutions

The PC 300PL 6565 includes IBM security solutions. IBM security solutions
help to make your electronic business transactions more secure. An
integrated security chip called the IBM Embedded Security Chip gives your
computer the functionality of a SmartCard without the added cost. IBM
security solutions also includes User Verification Manager software that
helps manage authentication so that you decide who has access to the
components of your system.

Using video features

Your computer has a video adapter preinstalled in the AGP slot. Some
models come with a super video graphics array (SVGA) adapter while
others come with a DVI (Digital Video Interactive) adapter. A DVI adapter
will also support an SVGA monitor by using a converter connected to the
output connector. Each of these adapters support 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 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 adapter and a README file with
instructions for installing the device drivers are provided on the Product
Recovery CD or the Device Driver and IBM Enhanced Diagnostics 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 need
to reinstall the device drivers or if you need information on obtaining and
installing updated device drivers.

See Chapter 7, “Getting help, service, and information” on page 127 for
more information.

Chapter 3. Operating and caring for your computer 33

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 the control panel of your
operating system. See 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

Your computer has an integrated audio controller that supports Sound
Blaster applications and is compatible with the Microsoft Windows Sound
System. These models also have a single internal speaker and three audio
connectors. The audio controller provides you with the ability to record
and play back sound and music and to enjoy sound with multimedia
applications. Optionally, you can connect stereo speakers to the line-out
connector 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 “Desktop model connections” on page 12 or “Tower model
connections” on page 13.)

34 PC 300PL and PC 300GL User Guide

Line/Headphone out

This jack is used to send audio signals from the computer to external
devices, such as powered stereo speakers with built-in amplifiers,
headphones, multimedia keyboards, or the audio line-in jack on a stereo
system.

Note: The internal speaker in your computer is disabled when an external

speaker is connected to the headphone connector on your computer.

Audio line in

This jack is used to accept audio signals from external devices (such as line
output from a stereo, television, or musical instrument) into the computer
sound system.

Microphone

This jack is used to connect a microphone to your computer when you want
to record voice or other sounds on the hard disk. This jack can also be
used with 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.
See 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 it is enabled. See “Setting
Remote Administration” on page 51 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.

Chapter 3. Operating and caring for your computer 35

Instructions for using system program updates are available in a README
file included in the update files.

Taking care of your computer

Follow these 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 allow air flow to keep your
computer and monitor 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 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.

36 PC 300PL and PC 300GL User Guide

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.

Chapter 3. Operating and caring for your computer 37

Moving your computer

Take the following precautions before moving your computer.

1. Back up all files and data from the hard disk.
Operating systems can vary in the way they perform backup

procedures. See your operating system documentation for information
about software backup.

2. Remove all media (such as diskettes, compact discs, and tapes) from
the drives.

3. Shut down your operating system and turn off the computer and all
attached devices. Your hard disk drive automatically parks the
read/write heads in a nondata area. This process prevents damage to
the hard disk.

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 damage.

Using passwords

You can use passwords to provide security for your computer and data.
You can set two kinds of passwords: a power-on password and an
administrator password. You do not have to set a password of either type
to use your computer. However, if you decide to set one, read the
following sections before you do so.

Note: When typing passwords that include numeric characters, do not use

the numeric keypad.

Using a power-on password

The Power-on Password feature deters unauthorized persons from gaining
access to your computer. 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 operating system will
not start, and you will not be able to use the keyboard to input
any other information. If you have a mouse connected to the
mouse port, it 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 Remote Administration is enabled, you cannot select

On. In this case, select Dual. If you try to 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 51.

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, see the following
information.

42 PC 300PL and PC 300GL User Guide

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. In this mode, the
mouse device driver does not load automatically. Instead,
the operating system displays an error message that
informs you that the mouse connector is disabled. To
enable the operating system to load without displaying this
error message on future restarts, type either your power-on
or administrator password and press Enter. Then use the
tab key and spacebar on 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 computer will remain locked until you type your
password. However, the mouse connected to the mouse
port remains locked.

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. See page 42 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. See page 42 for further
information.

Once you enter your power-on password, 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
unlock, and the computer begins normal operation.

Chapter 4. Configuration/Setup Utility program 43

Using an administrator password

Important

If Enhanced Security is enabled, keep a record of your administrator
password in a secure place. If you forget or lose the administrator
password, you must replace the system board in order to recover.

Setting an administrator password deters unauthorized persons from
changing configuration settings. If you are responsible for maintaining the
settings of several computers, you might want to set an administrator
password.

After you set an administrator password, a password prompt appears each
time you try to access the Configuration/Setup Utility program. If you type
the wrong password, you receive a message telling you so. If you type the
wrong password three times in succession, you must turn the computer off
and start again.

If both a power-on and administrator password are set, you can type either
of the passwords. However, in order to change any settings, you must use
your administrator password. If you enter the power-on password, you

46 PC 300PL and PC 300GL User Guide

After clearing CMOS memory, you must reconfigure the computer. After
reassembling the computer, use the Configuration/Setup Utility program to
reset the date and time, reset any passwords, and reconfigure the computer.

Using Security Profile by Device

Security Profile by Device enables you to control the level of security for the
following:

 IDE controller (for example, hard disk drives) - when the feature is set

to Disable, all devices connected to the IDE controller are disabled and
will not appear in the system configuration.

 Diskette Drive Access - when the feature is set to Disable, the diskette

drive cannot be accessed.

 Diskette Write Protect - when the feature is set to Enable, all diskettes

are treated as if write-protected.

Setting Security Profile by Device also enables you to control which devices
require a password before they start up. There are three classes of these
devices:

 Removable media, such as diskette drives and CD-ROM drives
 Hard disk drives

 Network devices
You can set these devices to request a user password, an administrator

password, or not to require a password. This way, if you have a power-on
or administrator password set for your system, you can configure your
computer to prompt you for a password only when certain devices are
accessed at startup. For example, if you set Hard Disk Devices to require a
User password, each time you attempt to start up from the hard disk, you
will be prompted to type the password before the startup proceeds.

Some operating systems require you to type a password before the
operating system will load. Security Profile by Device does not change the
way the operating system works. If an operating system password is
required, you must still type it when prompted, regardless of the Security
Profile by Device settings.

To set Security Profile by Device:

1. Start the Configuration/Setup Utility program (see “Starting and using
the Configuration/Setup Utility program” on page 39).

2. From the Configuration/Setup Utility program menu, select System
Security and press Enter.

Using Enhanced Security

Enhanced Security is an additional security feature available on the PC
300PL 6565.

Enhanced Security can be enabled or disabled only when you update
system programs. If Enhanced Security is enabled and you have not set an
administrator password, your computer will operate as if Enhanced Security
is disabled. For more information about setting an administrator password,
see “Using an administrator password” on page 45.

If Enhanced Security is enabled and you have set an administrator
password, your computer has these additional security measures:

 The contents of the security EEPROM (your administrator password

and startup sequence) are protected if the battery or CMOS memory
fails.

 The security EEPROM is protected from unauthorized access. The

security EEPROM cannot be read from or written to by any software
application or system software until Enhanced Security is disabled and
the computer is restarted. In a network environment, this might
prevent certain functions from being performed on your computer.

 Remote Administration is locked and cannot be unlocked until

Enhanced Security is disabled and the computer is restarted. This
prevents the system programs in your computer from being updated
remotely.

 The configuration settings in the Configuration/Setup Utility program

are protected and cannot be changed until you enter the administrator
password. Any changes in computer hardware detected by the system
programs in your computer will generate a configuration error until
you enter the administrator password.

To enable or disable Enhanced Security:

1. Insert a system programs update diskette into the diskette drive (drive
A) in your computer. System programs updates are available at
http://www.ibm.com/pc/support/us/ on the World Wide Web.

48 PC 300PL and PC 300GL User Guide

2. Turn on the computer. If it is on already, you must turn it off and
back on again.

3. The update begins, your computer halts, and you are prompted for
your administrator password (if you have set an administrator
password). The computer remains in a halted state until you enter the
administrator password.

4. When you enter the administrator password, or if no administrator
password has been set, the update diskette will continue to run, and
you are given the option of enabling or disabling Enhanced Security.
Your choice is automatically recorded in the System Security menu of
the Configuration/Setup Utility program.

Chapter 5. Installing options

You can expand the capabilities of your computer by adding memory,
drives, or adapters. When adding an option, use these instructions along
with the instructions that come with the option.

Attention

 Before you install or remove any option, read the “Safety

information” on page ix. These precautions and guidelines will
help you work safely.

 The presence of 5 V standby power might result in damage to your

Handling static-sensitive devices

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

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.

Setting the diskette write-protect switch

The diskette write-protect switch controls whether you can write
information to a diskette using a diskette drive. The ability to prevent
writing to a diskette is particularly useful if you are concerned about the
security of information that can be obtained through a network.

Note:

This switch does not affect the ability to read information from a diskette.

Before you begin:

 Read “Safety information” on page ix and “Handling

static-sensitive devices” on page 61.

 Turn off the computer and all other connected devices.
 Disconnect all cables attached to the computer and remove the

computer cover (see “Removing the cover — tower model” on
page 68 or “Removing the cover — desktop model” on page 64).

1. Locate the small rocker switch on the system board. See the label
inside the computer or “Identifying parts on the system board” on
page 74. It might be helpful to use a small screwdriver to set the
switch.

2. Set the switch as follows:

 For read-only diskette operation, set switch 1 to the ON position.

Write-protect is now enabled.

 For normal diskette operation, set switch 1 to the OFF position.

Write-protect is now disabled.

Working with adapters

This section provides information and instructions for installing and
removing adapters.

PCI adapters

All adapters supported by your computer use Plug and Play technology that
enables the computer to automatically configure the adapter. For more
information, see “Updating the computer configuration” on page 97.

Adapter slots

Your computer system board has three peripheral component interconnect
(PCI) expansion slots used to connect adapters to the bus. There is also one
AGP adapter slot. You can install an adapter up to 330 mm (13 inches)
long in the desktop model and 228 mm (9 inches) long in the tower model.
