About This Book xiii

xiv 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.

 Copyright IBM Corp. 1997 1

What Your IBM Personal Computer Offers

This section describes many of the features of your computer.

Support for Pentium Pro Microprocessors

At the core of your PC is an Intel Pentium Pro microprocessor. With its advanced
performance features, this microprocessor supplies the speed and power you need
to take advantage of even the most complex programs.

Your computer supports dual microprocessors, which means that you can upgrade
processor performance by adding a second microprocessor to the system board.
When you add a second microprocessor, the internal and external speeds of the
second microprocessor must be equivalent to those of the primary microprocessor.

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 processor 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 monitor and the hard disk drives.

Expansion with Adapters

Your computer has an ISA/PCI riser card for installing optional adapters. By
installing adapters, you can expand the capabilities of your PC and take advantage
of a variety of peripheral devices and applications. Examples of adapters that can
be added to your computer include graphics, SCSI (small computer system
interface), and LAN (local area network) adapters.

2 Using Your Personal Computer

High-Capacity Hard Disk Drives

Some PC models have a hard disk drive with an EIDE (enhanced integrated drive
electronics) bus master interface to transmit data to and from the hard disk drive.
The EIDE interface specification, which is an extension of the original IDE interface
specification, refers to a hard disk drive with the controller built into the drive (as
opposed to a hard disk drive with a separate controller). The single-unit drive and
controller plugs into one of two EIDE connectors located on the system board of
your computer. You can connect an additional hard disk drive to the ribbon cable
already attached to the system board. You can also purchase another cable and
connect two more hard disk drives or other IDE or EIDE devices to the second
connector on the system board. Your computer will accommodate up to four IDE
or EIDE devices. Both EIDE connectors are attached through a PCI-based controller.

Some PC models have a hard disk drive with a type of interface referred to as SCSI
(small computer system interface). These computers have a SCSI adapter installed
in one of the expansion slots. The SCSI adapter has one external 68-pin, 16-bit
connector; one internal 50-pin, 8-bit internal connector; and one internal 68-pin,
16-bit connector. With this adapter, you can connect up to 15 peripheral devices to
your PC. (However, the number of internal SCSI devices you can install is limited
by the number of available drive bays in your computer.)

SCSI can be faster than EIDE, particularly when used with a multitasking operating
system, such as OS/2 or Microsoft Windows NT. With SCSI, instructions can be
sent concurrently to every drive in the system, and the drives can then execute these
instructions simultaneously. This is not possible with EIDE. Also, with SCSI, it is
possible to add more peripheral devices to your PC than with EIDE. SCSI is well
suited for high-performance computers, or for computers in which expandability is
important. However, EIDE is desirable for many computer users because it is more
economical than SCSI, it has high-performance capabilities, and it is easier to
connect devices. Also, when used in a stand-alone computer with a single-tasking
operating system, such as DOS or Windows, EIDE can sometimes be faster than
SCSI.

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.

Chapter 1. Your IBM Personal Computer 3

PD/CD-ROM Drive

A PD/CD-ROM drive is preinstalled in some PC models. This dual-function IDE
drive can be used as a standard CD-ROM reader or as a mechanism for day-to-day
backup and storage of data. Using removable, rewritable optical disks called PD
cartridges, you can save, store, and read files just as you would with a hard disk
drive. PD cartridges, which store 650 MB of data, are particularly useful for
performing system backups and for saving space-consuming data, such as graphic
and multimedia files.

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
devices.

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 Port

Your computer has one standard 9-pin, 16550-UART serial port that can be used to
communicate with devices such as modems, plotters, and printers.

Universal Serial Bus Port

The Universal Serial Bus (USB) interface is based on a new, emerging technology
being developed to add more diversity and capabilities to personal computers. IBM
has provided one 4-pin USB connector on 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 port on your computer. Because
USB incorporates Plug and Play technology, you can install and remove devices
without turning off your computer. Once installed, the devices configure
automatically. In addition, an option called a hub enables you to plug in more than
one device at a time. A hub converts a single USB connector into multiple ports

4 Using Your Personal Computer

where USB devices can be attached. Note that your computer does not support a
keyboard or mouse attached to the USB port.

Watch the USB web site at www.teleport.com/ ˜USB for further developments.

Infrared Port

With infrared technology, wireless communication is possible between
infrared-enabled devices. Your PC has one infrared port to which you can connect
an optional infrared-transceiver module. The software required for infrared
communication is available on the Ready-to-Configure CD that comes with your
computer. (If you have Windows 95, you also need to install an infrared device
driver, which can be downloaded from the Microsoft Windows 95 Updates World
Wide Web site.) The infrared port, transceiver module, and software enable your
computer to transfer data to and from other infrared-capable devices, such as
portable computers and printers.

Video

Your computer has a preinstalled graphics adapter. Some models feature an S3
Trio64V+ graphics adapter while others have a Matrox MGA Millennium graphics
adapter. Each of these adapters provide a monitor connector. The Matrox MGA
Millennium graphics adapter also has a multimedia upgrade connector (video
feature connector). By attaching an optional Media/XL kit to this connector, you
can capture video from an external source, such as a VCR. Media/XL kits can be
purchased from Matrox Electronic Systems, Ltd.

Wake on LAN

If your computer has a properly configured token-ring or Ethernet LAN adapter
that is Wake on LAN-enabled and you have remote network management software,
you can use the IBM-developed Wake on LAN feature. For this feature to function
correctly, you must enable the Wake on LAN setting in the Configuration/Setup
Utility program of your computer.

If the PCs in your network are all Wake on LAN-enabled, you can use the Wake on
LAN function to turn on any or all of the networked PCs so that your remote
network management software can perform the tasks it has been programmed to
do. For instance, when Wake on LAN is used with IBM's remote network
management software, TME 10 NetFinity Version 4, you can perform functions such
as asset tracking and software and device driver updates on remote PCs after hours
and on weekends. Wake on LAN and NetFinity work together to turn on the
networked computers and make the appropriate updates. This saves time and

Chapter 1. Your IBM Personal Computer 5

increases productivity because users are not interrupted during normal working
hours and LAN traffic is kept to a minimum.

IBM-Preinstalled Software

IBM-preinstalled software is provided with some PC models. This software,
installed by IBM during manufacture of the computer, includes an operating system,
device drivers to support built-in features, and other support programs. Detailed
information about this software is included in About Your Software, which is
included with the preinstallation package.

Operating System Support

Your computer is designed to use a variety of operating systems in order to meet
your particular needs. See page 14 for a list of operating systems that you can use
with your PC.

Ease-of-Use Features

Your computer has many features that make it easy to work with, including Plug
and Play technology and easy-to-use diagnostic programs.

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 (QAPlus/PRO) that you can run to help determine if a hardware
component is causing the problem. QAPlus/PRO and other operating
system-specific diagnostic programs are included on the Ready-to-Configure CD that
comes with your computer. (Create the QAPlus/PRO diskette as soon as possible,
so that you will be ready to diagnose a problem if one should occur.)

Ergonomic Features

Your PC has ergonomic features which make it more comfortable to use. The
power switch and indicator lights are located on the front panel for easy access and
visibility. Also, you can easily change monitor settings to reduce or eliminate flicker
and jitter, and you can adjust the angle of the keyboard to make typing more
comfortable.

6 Using Your Personal Computer

Advanced Power Management

Energy conservation is an important concern. Your computer has Advanced Power
Management (APM) features that allow you to set different levels of energy
conservation for specific components of your computer. You can view and change

Your PC has security features that protect both hardware and software. For
example, you can set power-on and administrator passwords to deter unauthorized
persons from gaining access to your software. A cover lock helps prevent others
from tampering with the hardware components inside your computer, and a
lockable sliding door restricts access to the removable-media bays. Also, you can
select a secure startup sequence so that only certain drives are available for use, and
you can prevent the diskette drive from writing to diskettes.

Service and Support

You can obtain assistance for using your computer, as well as service, from a
number of sources. Help is available by phone, fax, and modem. For detailed
information, see Chapter 6, “Getting Help, Service, and Information” on page 99.

Expandability

You can easily expand the capabilities of your computer by adding memory, drives,
adapters, or an additional microprocessor.

Drive Bays: Your computer has five drive bays. Several of these bays are

unoccupied and can be used for installing additional devices such as hard disk,
diskette, CD-ROM, and PD/CD-ROM drives. The particular drive bays that are
occupied vary by computer model.

The following illustration shows the occupied and unoccupied drive bays in PC
models with a preinstalled EIDE hard disk drive.
