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.

Installing internal drives

This section provides information and instructions for installing and removing 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 of the different drives that are available for your computer are:

• Hard disk drives

• CD-ROM drives

• Removable media drives

Internal drives are installed in bays. Within this book, the bays are referred to as bay 1, bay 2,
and so on.

When you install an internal drive, it is important to note what type and size of drive that you can
install in each bay. Also, it is important to correctly connect the internal drive cables to the
installed drive.

Drive specifications

Your computer comes with the following IBM-installed drives:

• A CD-ROM drive, DVD-ROM, or other type of drive in bay 2 (some models)

• A 3.5-inch hard disk drive in bay 1

• A 3.5-inch diskette drive in bay 3 (some models)

Models that do not have drives installed in bays 2 and 3 have a static shield and bay panel
installed.

The following illustration shows the locations of the drive bays.

The following table describes some of the drives that you can install in each bay and their height
requirements.

Bay 1 - Max Height: 25.4 mm (1.0 in.)
Bay 2 - Max Height: 41.3 mm (1.6 in.)
Bay 3 - Max Height: 25.4 mm (1.0 in.)

Notes:

1.Drives that are greater than 41.3 mm (1.6 in.) high cannot be installed.

2.Install removable media (tape or CD) drives in the accessible bay: bay 2 or 3.

20Installing internal options-desktop model

Power and signal cables for internal drives

Your computer uses cables to connect integrated drive electronics (IDE) drives to the power
supply and to the system board. The following cables are provided:

• Four-wire power cables connect most drives to the power supply. At the end of these
cables are plastic connectors that attach to different drives; these connectors vary in size.
Also, certain power cables attach to the system board.

• Flat signal cables, also called ribbon cables, connect IDE and diskette drives to the system
board. There are two sizes of ribbon signal cables that come with your computer:

— The wider signal cable has two or three connectors.

– If the cable has three connectors, one of these connectors is attached to the drive,

one is a spare, and the third is attached to the primary or secondary IDE
connector on the system board.

– If the cable has two connectors, one of these connectors is attached to the hard

disk drive, and the other is attached to the primary or secondary IDE connector on
the system board.

Note: If you want to add another device, and your computer does not come with

a standard CD-ROM, you will need a second signal cable with three
connectors. You will need an 80-conductor ATA 100 signal cable if you are
replacing the existing signal cable or adding a second hard disk drive.
ATA 100 signal cables are color-coded. The blue connector is attached to
the system board, the black connector is attached to the master device,
and the gray middle connector is attached to the secondary (or slave)
device.

If your computer comes with a CD-ROM drive, it has an ATA 100 signal
cable. However, if you are installing a hard disk drive, you must change
the switch or jumper setting on the CD-ROM drive to secondary and
change the connector that is used for the CD-ROM drive to the gray
middle connector.

— The narrower signal cable has two connectors for attaching the diskette drive to the

diskette-drive connector on the system board.

Note: To locate connectors on the system board, see ”Identifying parts on the system board”

on page 16.

The following are some important points to remember when connecting power and signal
cables to internal drives:

• The drives that are standard in your computer come with power and signal cables attached.
If you replace any drives, it is important to remember which cable is attached to which
drive.

• When you install a drive, ensure that the drive connector at the end of the signal cable is
always connected to a drive; also, ensure that the drive connector at the other end is
connected to the system board. This reduces electronic noise from the computer.

• If two IDE devices are used on a single cable, one must be designated as the primary, or
master, device and the other as the secondary, or slave, device; otherwise, some of the
IDE devices might not be recognized by the computer. The primary or secondary
designation is determined by switch or jumper settings on each IDE device.

• If two IDE devices are on a single cable and only one is a hard disk drive, the hard disk
drive must be set as the master device.

• If you have only one IDE device on a cable, it must be set as master.

For help in selecting drives, cables, and other options for your computer, see ”Available options”
on page 7.

Power and signal cables for internal drives

Your computer uses cables to connect integrated drive electronics (IDE) drives to the power
supply and to the system board. The following cables are provided:

• Four-wire power cables connect most drives to the power supply. At the end of these
cables are plastic connectors that attach to different drives; these connectors vary in size.
Also, certain power cables attach to the system board.

• Flat signal cables, also called ribbon cables, connect IDE and diskette drives to the system

What to do next

• To work with another option, go to the appropriate section.

• To complete the installation, go to “Replacing the cover and connecting the cables”
on page 34.

Replacing the cover and connecting the cables

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

To replace the cover and connect cables to your computer:

1. Ensure that all components have been reassembled correctly and that no tools or loose
screws are left inside your computer.

2. Clear any cables that might impede the replacement of the cover.

3. Position the cover over the chassis so that the front edge is approximately one inch away
from the front bezel.

4. Lower the cover down over the chassis so that the rail guides engage the rails.

5. Slide the cover forward. You might need to lift the front of the cover slightly to align it
properly.

6. Insert the three thumbscrews into the holes in the cover and the chassis and tighten.

7. Reconnect the external cables and cords to the computer. See “Installing external options”
on page 9.

Important:

When the power cord is first plugged in, the computer might appear to power on for a
few seconds, then power off. This is a normal sequence to enable the computer to
self-initialize.

Start Options

The start options are settings that affect the way your computer acts when started.

Startup Sequence

This setting controls which devices your computer will attempt to read data from when it is
started.

Your computer can be started from several devices, including the hard disk drive, diskette
drive, and CD-ROM drive. The startup program looks for these devices in a selected
sequence. The startup sequence on your computer is preset from the factory to have the
computer start up from a CD-ROM, diskette, or hard disk. This startup sequence allows you
to start the diagnostic and recovery programs from the Product Recovery and Diagnostics
CD, use emergency diskettes to recover from a startup failure, and start from your hard disk
for normal day-to-day operation. In order to boot from the CD-ROM, place CD Drive before
HDD in the boot sequence list.

Virus Warning

This setting determines if the BIOS will monitor the boot sector and partition table of the hard
disk drive for any attempt at modification. If any attempt is made, the BIOS will halt the
system and an error message will appear.

Afterwards, if necessary, you will be able to run an anti-virus program to locate and remove
the problem before any damage is done.

Enabled Activates automatically when the system boots up causing a warning message

Disabled No warning message will appear when anything attempts to access the boot
Note: Many disk diagnostic programs that attempt to access the boot sector table can

cause the above warning message. If you are running such a program, you can
avoid the virus warning by disabling the virus protection before you run the program.
After running the program, remember to re-enable virus protection.

Quick Power-On Self Test

This setting causes the computer to run a shortened power-on self test (POST). The
shortened POST takes less time to complete, but does not test the computer as thoroughly
as the normal POST.

Enabled Enable quick POST
Disabled Normal POST

39

Boot Up Floppy Seek

This setting determines whether or not the computer will check for the presence of a diskette
drive at startup.

Boot Up NumLock Status

This setting determines the default state of the numeric keypad. By default, the system boots
up with NumLock on.

On The numeric keypad provides numeric functions.
Off The numeric keypad provides arrow-key, Home, PgUp, PgDn, End, Insert, and Delete

functions.

Gate A20 Option

This entry allows you to select how the gate A20 is handled. The gate A20 is a device used
to address memory above 1 Mbytes. Initially, the gate A20 was handled via a pin on the
keyboard. Today, while keyboards still provide this support, it is more common, and much
faster, for the system chipset to provide support for gate A20.

Normal keyboard
Fast chipset

Typematic Rate Setting

This setting determines whether or not the typematic (repeat) function is enabled. If the
typematic function is enabled and a key is held down, the key will repeat after a brief delay. If
the typematic function is disabled, the key will not repeat when held brief delay. If the
typematic function is disabled, the key will not repeat when held.

Enabled Enable typematic rate (repeat)
Disabled Disable typematic rate (no repeat)

Typematic Rate (Chars/Sec)

When the typematic rate is enabled, you can select the rate at which the keys are repeated.

Typematic Delay (Msec)

When the typematic rate is enabled, you can select the delay between when the key was first
depressed and when the acceleration begins.

Halt When Error occurence

This option allows system halt when POST error occur. Select "Enabled" system will halt and
"Disabled" system will halt for 5 seconds then POST continues

Halt On

Use this setting to determine under what conditions the power-on self test (POST) will halt
when errors are detected.

ALL errors System halts in case of any errors
No errors System won’t halt in case of any errors
ALL, But keyboard System halts except for the keyboard error
ALL, But diskette System halts except for the diskette error
ALL, But disk/key System halts except for the diskette or keyboard error

42 Updating the computer configuration

Your computer has a special type of memory that maintains the date, time, and 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 vi for information about replacing and disposing of the
battery.

To change the battery:

1. Turn off the computer and all attached devices.

2. Unplug the power cord and remove the cover. See “Removing the cover” on page 15
(desktop model), “Removing the cover” on page 25 (microtower model).

3. Locate the battery. Refer to the system board label inside your computer or see “Identifying

parts on the system board” on page 16 (desktop model), or “Identifying parts on the system
board” on page 28 (microtower model).

4. If necessary, remove any adapters that impede access to the battery. See “Installing
adapters” on page 19 (desktop model), or “Installing adapters” on page 31 (microtower) for

more information.

5. Remove the old battery.

43

6. Install the new battery.

7. Replace any adapters that were removed to gain access to the battery. See “Installing
adapters” on page 19 (desktop model), or “Installing adapters” on page 31 (microtower
model) for instructions for replacing adapters.

8. Replace the cover and plug in the power cord. See “Replacing the cover and connecting

the cables” on page 23 (desktop model), “Replacing the cover and connecting the cables”
on page 34 (microtower model) and the Quick Reference.

Note: When the computer is turned on for the first time after battery replacement, an error

message might be displayed. This is normal after replacing the battery.

9. Turn on the computer and all attached devices.

10. Use the Configuration/Setup Utility program to set the date and time and any passwords.

11. Dispose of the old battery as required by local ordinances or regulations.

44 Changing the battery

The following contains information about updating system programs (POST/BIOS) and how to
recover from a POST/BIOS update failure.

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.

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 (see Quick
Reference). Instructions for using the system programs updates are available in a README file
included in the update files.

To update system programs (flash the EEPROM):

1. Insert a system programs update (flash) diskette into the diskette drive (drive A) in your

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