4 Installing Options in Your Personal Computer
Handling Static-Sensitive Devices
Have you ever walked across a carpeted floor, then touched an object and received
a small electrical shock? That's static electricity, and although harmless to you, it
can seriously damage computer components and options.
Important
When you add an option, do not open the static-protective package containing
the option until you are instructed to do so.
When you handle options and other computer components, take these precautions
to avoid static electricity damage:
Limit your movement. Movement can cause static electricity to build up around
you.
Always handle components carefully. Handle adapters and memory-modules
by the edges. Never touch any exposed circuitry.
Prevent others from touching components.
When you are installing 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.

Chapter 4. Working with Adapters
This chapter provides information and instructions for installing and removing
adapters.
When you are installing or removing adapters, it is important to resolve any
resource conflicts that might arise. For example, if you install an ISA legacy
adapter, you might need to manually configure the adapter by setting a variety of
switches on the adapter and by using the Configuration/Setup Utility program.
Many adapters now use Plug and Play technology, which enables the computer to
automatically configure the adapter, provided that the required resources are
available. Refer to the instructions that come with your adapter to determine if it is
Plug and Play. For more information, see “Adapter Configuration” on page 26.
Important Information
Run ConfigSafe (or a similar application) to take a snapshot of your computer
configuration before installing an adapter. This allows you to view and
compare the changes in the computer configuration after you install an
adapter. Also, if you have problems configuring the adapter after it is
installed, ConfigSafe allows you to restore the configuration to the previous
settings.
ConfigSafe is a part of the preinstalled software in your computer. For more
information, see About Your Software that comes with your computer.
Be careful when working near the microprocessor. Under normal use, the
microprocessor can become very hot.

Adapters and the Riser Card
Your computer uses a riser card for expansion. The riser card contains expansion
slots that connect adapters to the industry standard architecture (ISA) and
peripheral component interconnect (PCI) buses.
You can install a variety of adapters in the expansion slots on the riser card. For
information on locating the riser card, see “Locating Components” on page 8.
The riser card in your computer has three dedicated ISA slots and three dedicated
PCI slots.
The following illustration shows the expansion slots and connectors on the riser
card.

Adapter Configuration
Along with the documentation that comes with your adapter, use the following
information to help with adapter configuration.
Plug and Play Adapters
Your computer uses the Plug and Play method to configure adapters. Support for
Plug and Play is built into the system board of your computer.
If an adapter is Plug and Play, there are no switches or jumpers that must be set on
the adapter. A Plug and Play adapter comes with configuration specifications set in
memory to provide installation information to the computer during startup. When
you install or remove Plug and Play adapters, this information is interpreted by the
basic input/output system (BIOS), which supports Plug and Play technology. If the
required resources are available, the BIOS software automatically configures the
adapter around the resources already in use by other devices.
Most adapters designed for PCI slots are Plug and Play devices; many ISA adapters
are not Plug and Play devices.
Notes:
1. If a resource conflict arises after installing a Plug and Play adapter, you might
need to change the default resource settings on the adapter. For more
information, refer to the documentation that comes with the adapter.
2. For information on error messages from resource conflicts, see Using Your
Personal Computer.
26 Installing Options in Your Personal Computer
Legacy Adapters
Adapters that are not Plug and Play-compatible are known as legacy devices. If you
install a legacy adapter, you must manually configure it by setting switches on the
adapter and by allocating system resources using the Configuration/Setup Utility
program.
In the Configuration/Setup Utility program, the ISA Legacy Resources screen shows
the computer resources that are typically required by adapters:
Memory resources
I/O port resources
DMA resources
Interrupt resources
From the appropriate screens, you can select available resources for the adapter you
are installing. Resources not being used by ISA legacy adapters are listed as
[Available]. You must set the resources used by the newly installed ISA legacy
adapter to [ISA Resource]; this reserves the resources for the legacy adapter and
prevents the BIOS from using these resources for the system or other Plug and Play
adapters.
Just as you change system resources when you install an ISA legacy adapter, you
must also change resources when you remove an ISA legacy adapter. If you
remove a legacy adapter, change the resources that were being used to [Available].
This allows the Plug and Play software to automatically use these resources for
future configurations, or they can be used later when other legacy adapters are
installed.
Note: Refer to the documentation that comes with the adapter for information on
required system resources.
For information on configuring ISA legacy adapters, see “Configuring an ISA
Legacy Adapter” on page 81 or refer to Using Your Personal Computer. For
information on error messages from resource conflicts, see Using Your Personal
Computer.

Internal Drives
Internal drives are devices that your computer uses to read and store data. You can
add drives to your computer to increase storage capacity and to enable your
computer to read other types of media. Some types of drives available for your
computer are:
Hard disk drives
CD-ROM drives
Internal drives are installed in bays at the front and rear of your computer. The
bays are referred to as bay 1, bay 2, and so on.
Drive bays 1 through 4, at the front of your computer, are contained in one drive
cage, and drive bays 5 and 6, at the back of your computer, are contained in
another.
Your computer comes with the following IBM-installed drives:
A 3.5-inch diskette drive in bay 4
A 3.5-inch hard disk drive in bay 6
A CD-ROM drive in bay 1 (in some models)
The following illustration shows the location of the drive bays in your computer.

Power and Signal Cables
Your computer uses cables to connect the power supply to the riser card and to
integrated drive electronics (IDE) drives. The diskette drive is also powered
through a cable attached to the riser card. The following cables are provided:
Four-wire power cables connect most drives to the power supply. At the ends of
these cables are plastic connectors that attach to different drives; these
connectors vary in size. Also, some power cables attach to the riser card.
Flat signal cables, sometimes called ribbon cables, connect IDE drives to the riser
card. There are two sizes of signal cables that come with your computer:
– The wider signal cable attaches to the installed hard disk drive and to the
primary IDE connector on the back of the riser card.
– The narrower signal cable attaches to the diskette drive and to the diskette
drive connector on the back of the riser card.
The following illustration shows the connectors on the riser card.

The following are some important points to remember when connecting power and
signal cables to internal drives:
The diskette drive and hard disk drive that are preinstalled in your computer
come with power and signal cables attached. If your computer comes with a
CD-ROM drive, it is attached to the secondary IDE connector on the back of the
Chapter 5. Working with Internal Drives 45
riser card. If you replace any drives, it is important to remember which cables
are attached to which drives.
When you install a drive, ensure that the drive connector at the end of the
signal cable is always connected to the drive; also, ensure that the drive
connector at the other end is connected to the riser card. This reduces electronic
noise from the computer.
If more than one IDE device is used on a single cable, one must be designated
as the primary or master device and all others as slave or subordinate devices;
otherwise, some of the IDE devices might not be recognized by the system. The
master or slave designation is determined by switch or jumper settings on each
IDE device.
To optimize performance when installing more than two hard disk drives, be
sure to attach hard disk drives with faster data transfer speeds (Mode 1 or
higher) to the primary hard disk drive signal cable (hard disk drives 0 and 1).
On some models, to install more than one IDE hard disk drive, you must
purchase an additional signal cable. The cable must meet the following
specifications:
– Maximum length: 0.46 meters (18 inches)
– Wire size: 28 AWG
– Cable capacitive loading: 200 pF maximum
You can install one diskette drive only.

Working with Drives in Bays 1, 2, 3, or 4
There are two different designs for the front drive cage that contains drive bays 1
through 4. One design has a drive cage that must be removed when you install or
remove drives. With the other design, you install drives from the front of the
computer without removing the drive cage. In this type, the drive cage is
permanently mounted to the chassis and cannot be removed. To determine which
type of chassis you have, look for the support bracket and screw that secures the
front drive cage. If your chassis does not have these, then you have the
permanently mounted drive cage. The procedure for installing and removing
drives is different for each type.

The following list is a quick reference to these procedures:
“Installing a U-Bolt” on page 68
“Erasing Lost or Forgotten Passwords” on page 70
Copyright IBM Corp. 1998 67
Installing a U-Bolt
You can add a U-bolt to the rear of your computer. Adding a U-bolt enables you to
add a security cable and lock which helps prevent hardware theft. After you add
the security cable, make sure that it does not interfere with other cables that are
connected to the computer.
Before you begin
Obtain the following:
– A 19-mm (3/4 in.) U-bolt and threaded nuts that fit the U-bolt
– A security cable
– A lock, such as a combination lock or padlock
– An adjustable wrench
Read “Electrical Safety” on page 4 and “Handling Static-Sensitive Devices”
on page 5.
Turn off the computer and all connected devices.
Disconnect all external cables and power cords, and remove the computer
cover (see “Disconnecting Cables and Removing the Side Cover” on page 6).
Note: The external connectors on the rear of your computer might differ from the
ones shown in this section.
1 Locate the two holes on the lower right edge of the rear of the computer.
2 Insert the U-bolt through the rear panel; then, attach and tighten the nuts with
an adjustable wrench.
68 Installing Options in Your Personal Computer

Erasing Lost or Forgotten Passwords
Note: To set a new password after completing this procedure, see “Setting
Passwords” on page 83.
Your computer uses complementary metal-oxide semiconductor (CMOS) memory on the
system board for storing configuration and setup information. CMOS memory
maintains information about:
Date and time
Security features
Power-management devices
Storage devices
Keyboard and mouse
ISA legacy configuration information
Plug and Play configuration information
Port assignments
I/O addresses and interrupts
Other selectable features
Within the security features are the settings for the power-on and administrator
passwords. If you need to erase a lost or forgotten password, you must move a
jumper to clear CMOS memory.
Important
Clearing CMOS memory sets the configuration of your computer to the default
settings. Because you need to reconfigure the computer after clearing CMOS
memory, if possible, record the configuration information of your computer
before moving the Clear CMOS jumper.
