Chapter 1. Overview 3

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.

Identifying Parts on the System Board

The system board, also called the planar or motherboard, is the main circuit board in your computer. It provides basic computer functions and supports a variety of devices that are IBM-installed or that you can install later.

If you plan to install, remove, or replace hardware in your computer, you need to know the layout of the system board. The following illustration shows the layout of the system board in your computer. The numbered pointers show the components that are discussed in this book.

.1/ Battery .2/ Microprocessor-speed switches .3/ Microprocessor .4/ DIMM 0 .5/ DIMM 1 .6/ DIMM 2 (not on all models) .7/ Clear CMOS Request jumper .8/ AGP connector (some models only) .9/ Video memory connector (some models only)

Note: An illustration of the system board and additional information are provided

on a label found inside the computer.

Working with System Memory

You can add memory to your computer to increase system performance. Your computer has either two or three connectors (DIMM 0, DIMM 1, and DIMM 2) for installing system memory modules. If your computer has three connectors, the maximum amount of system memory your computer supports is 384 MB. If your computer has two connectors, the maximum amount of system memory your computer supports is 256 MB.

To locate the memory connectors inside your computer, see “Identifying Parts on the System Board.” DIMM 2 is not on all models.

Chapter 3. Working with Options on the System Board 11

DIMM 0 DIMM 1 DIMM 2

The memory modules your computer uses are dual inline memory modules (DIMMs).

If your computer has an Intel Pentium II or Pentium III processor, the IBM-installed DIMMs that come with your computer are non-parity or Error Checking and Correction (ECC) 100 MHz Synchronous Dynamic Random Access Memory (SDRAM) modules.

If your computer has an Intel Celeron processor, the IBM-installed DIMMs that come with your computer are non-parity or ECC 66 MHz SDRAM modules. However, not all models with an Intel Celeron processor support ECC memory.

When installing or replacing DIMMs, follow these guidelines:

 Use only 3.3 V dc, unbuffered, 100 MHz DIMMs on models with Intel Pentium

II processors.

 Use only 3.3 V dc, unbuffered, 66 MHz DIMMs on models with Intel Celeron

processors.

 Each memory connector supports a maximum of 128 MB of memory.  Install only ECC DIMMs to enable ECC. If you mix ECC DIMMs and

non-parity DIMMs, your memory will function as non-parity DIMMs.

Memory Configuration

When you are adding or removing memory, you can use any combination of DIMM sizes 16, 32, 64, or 128 MB. Be sure to fill each system memory connector sequentially, starting at DIMM 0. For the location of DIMM 0, see “Identifying Parts on the System Board” on page 11.

The following table shows possible memory configurations for your computer; this table and additional information are also found on a label inside the computer.

Chapter 4. Working with Adapters

This chapter provides information and instructions for installing and removing adapters, including instructions for working with adapters on the riser card and for installing an accelerated graphics port (AGP) adapter.

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 24.

Important

 Run ConfigSafe (or a similar application) to take a snapshot of your computer

configuration before installing an optional device. 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.

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 7.

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.

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.

24 Installing Options in Your Personal Computer

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.

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 71 or refer to Using Your Personal Computer. For information on error messages from resource conflicts, see Using Your Personal Computer.

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.

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

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.

40 Installing Options in Your Personal Computer

 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. Note: The IDE signal cable provided with the PC 300PL has a second

connector for attaching drives.

– The narrower signal cable attaches to the diskette drive and to the diskette

drive connector on the back of the riser card.

Each cable attaches to a connector on the riser card. To locate these connectors, see “Riser Card” on page 22. 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 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

This section provides instructions for two different mechanical drive cage designs that contain bays 1 through 4. One drive cage is removable, and the other is not. Because the procedure for installing and removing drives is different for each design, both designs are explained below to help you identify which one you have.

 Removable Drive Cage

Computers with the removable drive cage have a support bracket and screw that secure the front drive cage. If the drive support bracket is present, you must remove the drive cage before installing or removing drives (see “Removable Drive Cage Instructions”). The following illustration shows a computer with a removable drive cage.

Chapter 6. Working with Security Options

This chapter describes some of the security options that are available for your computer.

To help prevent hardware theft, you can add a security U-bolt and cable to your computer. To erase lost or forgotten passwords, you can move the Clear CMOS Request jumper on the system board.

Note: Use the Configuration/Setup Utility program to set, change, or delete

passwords. For more information, see Using Your Personal Computer.

The following list is a quick reference to these procedures:

 “Installing a U-Bolt”  “Erasing Lost or Forgotten Passwords” on page 62

Installing a U-Bolt

Adding a U-bolt to the rear of your computer 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 3 and “Handling Static-Sensitive Devices”

on page 4.

 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 Cover” on page 5).

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.

60  Copyright IBM Corp. 1999

2 Insert the U-bolt through the rear panel; then, attach and tighten the nuts with

an adjustable wrench.

3 Replace the computer cover. For more information, see “Replacing the Cover

and Connecting the Cables” on page 66.

4 Thread the cable through the U-bolt and around an object that is not a part of

or permanently secured to the building structure or foundation, and from which it cannot be removed, then fasten the cable ends together with a lock.

The following illustration shows an example of how this might work.

Erasing Lost or Forgotten Passwords

Note: To set a new password after completing this procedure, see Using Your

Personal Computer.

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

62 Installing Options in Your Personal Computer

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.

Enhanced Security Information for PC 300PL Models

Some models have a new, Enhanced Security feature that provides extra protection for your administrator password, as well as your startup sequence settings. With Enhanced Security enabled, your administrator password and startup sequence area 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 startup sequence are locked in the security EEPROM, they remain intact even if the battery in your computer expires or is removed by someone.

Be careful to keep a copy of your administrator password locked in a secure place, because if you have this Enhanced Security feature and forget your administrator password, your system will be unusable.

For more information on Enhanced Security, see Using Your Personal Computer.

Before you begin

 Using the Configuration/Setup Utility program, record all configuration

information. Clearing CMOS memory sets the configuration of your computer to the default settings. Because you need to reconfigure the computer after clearing CMOS memory, record the configuration information of your computer before moving the Clear CMOS Request jumper.

 Read “Electrical Safety” on page 3 and “Handling Static-Sensitive Devices”

on page 4.

 Turn off the computer and disconnect all cables except the power cord.  Remove the computer cover.  Lay the computer on its side.  Locate the Clear CMOS Request jumper. See “Identifying Parts on the

System Board” on page 11. Note: You might have to remove adapters to gain access to the jumper. See

“Removing Adapters from the Riser Card” on page 28.

1 Move the jumper from its normal position (pins 1 and 2) to pins 2 and 3. It

might be helpful to use needle-nose pliers to move the jumper, but be careful not to scrape any system board components or crush the jumper.

Chapter 6. Working with Security Options 63

CAUTION: Do not touch any of the internal components of the computer.

2 Reconnect the cables and turn on the computer. CMOS memory is now

cleared and the passwords have been erased. After the POST completes, configuration error messages are displayed.

3 Follow the instructions on the screen to continue. 4 When the Configuration/Setup Utility program starts, make the necessary

changes, save the settings, and exit setup. Refer to “Updating the Computer Configuration” on page 68. When the message is displayed that instructs you to move the jumper to the normal position, turn power off.

5 Disconnect the power cord from the rear of the chassis. 6 Move the jumper back to its normal position (pins 1 and 2).

64 Installing Options in Your Personal Computer

What to do next

After reassembling the computer (go to Chapter 7, “Completing the Installation” on page 66), use the Configuration/Setup Utility program to set any passwords or other configuration parameters. For more information, refer to Using Your Personal Computer.

Chapter 6. Working with Security Options 65

Chapter 7. Completing the Installation

After working with options, you need to install any removed parts, replace the cover, reconnect any cables, including power cords and telephone lines. In addition, depending on the option installed, you might need to update information in the Configuration/Setup Utility program.

The following list is a quick reference to the completion procedures:

 “Using the Stabilizing Feet”

 “Replacing the Cover and Connecting the Cables”

 “Updating the Computer Configuration” on page 68

Using the Stabilizing Feet

Updating the Computer Configuration

Important

The configuration information in this section applies to installing options. For more information on using the Configuration/Setup Utility program, see Using Your Personal Computer.

Also, you might need to install device drivers after updating the configuration settings. For more information, see the instructions that come with the option to determine if device drivers are required and how to install them. Also, video device drivers are on the Software Selections CD.

After you add, remove, or replace options, you must update the information in the configuration settings. This reconfiguration is performed automatically by the computer (but you must save the changes), or manually by you. When the computer automatically configures an option, it uses system programs. If the system programs do not update the settings, you can use the Configuration/Setup Utility program to reconfigure the appropriate settings.

For example, when you start your computer after adding most internal hard disk drives, the settings are automatically updated and you use the Configuration/Setup Utility program to save those changes. However, if a resource conflict arises after an ISA legacy adapter is installed or removed, you must manually update the computer configuration and save the information.
