General checkout

This general checkout procedure is for Types 6233 and 6850 computers.

Attention:

The drives in the computer you are servicing might have been rearranged or the drive
startup sequence changed. Be extremely careful during write operations such as copying,
saving or formatting. Data or programs can be overwritten if you select an incorrect drive.

Diagnostic error messages appear when a test program finds a problem with a
hardware option. For the test programs to properly determine if a test Passed,
Failed or Aborted, the test programs check the error-return code at test completion.
See “Diagnostics” on page 18.

General error messages appear if a problem or conflict is found by an application
program, the operating system, or both. For an explanation of these messages,
refer to the information supplied with that software package.

Notes:

v Types 6233 and 6850 computers default to come up quiet (no beep and no memory count and checkpoint code

display) when no errors are detected by POST.

v To enable beep and memory count and checkpoint code display when a successful POST occurs, do the following:

1. Select Start Options in the Configuration/Setup Utility program (see “Setup Utility program” on page 17).

2. Set Power-On Self-Test to Enhanced.

Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS

v

might cause false errors and unnecessary replacement of the system board. For more information on how to
determine and obtain the latest level BIOS, see “BIOS levels” on page 39.

v If multiple error codes are displayed, diagnose the first error code displayed.
v If the computer hangs with a POST error, go to “POST error codes” on page 91.
v If the computer hangs and no error is displayed, go to “Undetermined problems” on page 96.

10 Hardware Maintenance Manual: IBM IntelliStation M Pro Type 6233 and 6850

Operating certain features

This section provides an overview of some of the features of this computer.

Using video features

The computer has an accelerated graphics port (AGP) graphics adapter that uses a
standard video protocol for displaying text and graphic images on a monitor screen.
The adapter supports 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.

Video device drivers

To take full advantage of the graphics adapter in the computer, some operating
systems and application programs require custom software, known as video device
drivers. These preinstalled 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 Device Drivers and IBM Enhanced

Diagnostics CD that comes with the computer. If the computer has preinstalled

software, video device drivers are in the C:\IBMTOOLS\DRIVERS directory.

Note: Video device drivers for the Fire GL4 video adapter are in the

IBMTOOLS/DRIVERS/VIDEO/FIREGL4 directory.

You can use the device driver installation instructions if you ever need to reinstall
the device drivers, or if you need information on obtaining and installing updated
device drivers.

Changing monitor settings

To get the best possible image on the screen and to reduce flicker, you might need
to reset the resolution and refresh rate of the monitor. Yo u can view and change
monitor settings through the operating system using the instructions provided in the
README files on the Device Drivers and IBM Enhanced Diagnostics CD or in the
C:\ IBMTOOLS\DRIVERS directory on the hard disk drive.

Attention: Before you change any monitor settings, be sure to review the

information that comes with the monitor. Using a resolution or refresh rate that is
not supported by the monitor might cause the screen to become unreadable and
could damage the monitor. The information that comes with the 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 the monitor to the highest noninterlaced
refresh rate that the monitor supports. If the monitor complies with the VESA display
data channel (DDC) standard, it should already be set to the highest refresh rate
that the monitor and video controller can support. If you are not sure if the monitor
is DDC-compliant, see the documentation provided with the monitor.

If you have a dual-monitor video adapter and you connect both monitors but do not
see the second monitor, go to Start → Settings → Control Panel → Display

Properties → Settings → Display Type and enable the Multi-head option.

Note: Refer to the video adapter device driver README file and online help for

more information.

General information 11

Using audio features

The computer has three audio connectors, and an integrated audio controller that
supports Sound Blaster applications and is compatible with the Microsoft Windows
Sound System. Using the audio controller, you can record sound and music. If you
connect external speakers to the Line out connector, you can play sound with
multimedia applications.

The audio connectors in the computer are 3.5 mm mini-jacks. A description of the
connectors follows.

Line out

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

Line in

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

Mic

This connector is used to connect a microphone to the computer when you want to
record voices or other sounds on the hard disk drive. This connector and a
microphone can also be used by speech recognition software.

Note: If you experience interference or speaker feedback while recording, try

reducing the microphone recording volume (gain).

Updating system programs

System programs are the basic layer of software built into the 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 are performed each time you turn on the 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 the computer.

System programs are stored in an electrically erasable programmable read-only
module (EEPROM) on the system board. This is sometimes referred to as flash
memory.

IBM occasionally makes changes and enhancements to the system programs.
When updates are released, they are available as downloadable files on the World
Wide Web at http://www.ibm.com.

You can update system programs by starting the computer using a flash update
diskette or by using the Remote Administration feature, if it is enabled. Instructions
for using system programs updates are included in a README file provided with
the downloadable files.

12 Hardware Maintenance Manual: IBM IntelliStation M Pro Type 6233 and 6850

Managing the computer

The computer comes with features that a network administrator or file server can
use to remotely manage and control the computer.

IBM Director Agent

IBM Director Agent streamline and automate personal computer (PC) systems
management and support tasks, such as asset deployment and tracking. These
utilities are available for IBM computers at no additional charge, helping to reduce
the total cost of ownership of the networked computers.

IBM Director Agent enables you to view detailed information about the computer
hardware and software, set up alerts, monitor a variety of system resources, and
manage the asset security. For more information, go to
http://www.ibm.com/pc/support on the World Wide Web and search for IBM Director
Agent.

Wake on LAN

®

A network administrator can use Wake on LAN

to turn on the computer from a
remote location. When Wake on LAN is used with network management software,
many functions, such as data transfers, software updates, and POST or BIOS code
updates can be initiated on the computer remotely.

Note: If the computer power cord is plugged into a surge protector or power strip,

make sure that you turn off the computer by the power button, and not the
surge protector or power strip switch. Otherwise, the Wake on LAN feature
will not work.

Alert on LAN

The computer supports Alert on LAN technology, which provides notification of
changes in the computer system even when the computer is turned off. Working
with desktop management interface (DMI) and Wake on LAN technologies, Alert on
LAN helps manage and monitor the hardware and software features of the
computer.

Alert on LAN generates notifications when the computer cover is removed, an error
is detected during POST, or the computer is disconnected from the network or
unplugged from the electrical outlet. Alert on LAN works in conjunction with UM
Services.

Remote Program Load or Dynamic Host Configuration Protocol

A network administrator can use Remote Program Load (RPL) or Dynamic Host
Configuration Protocol (DHCP) to control the computer. RPL, when used with
software such as IBM LANClient Control Manager™, uses a feature called Hybrid

RPL to install hybrid images (or files) on the hard disk drive. If the computer is a

Hybrid RPL client, each time the computer starts from the network, LANClient
Control Manager downloads a small bootstrap program to the computer hard disk
drive and avoids the network traffic associated with a standard RPL.

DHCP enables network administrators centrally to manage and automate the
assignment of Internet Protocol (IP) addresses on a network.

General information 13

Remote Administration

A network administrator can use the Remote Administration feature to remotely
update the POST and BIOS code in the computer.

Network-management software, such as LANClient Control Manager (LCCM), is
required to take advantage of this feature.

LANClient Control Manager

LANClient Control Manager is a graphical, computer-based system deployment
program that enables mass unattended installations of operating systems, software
images, device drivers, and BIOS code updates to remote systems. When used
with Wake on LAN, LCCM can remotely turn on the computer, so that the
installation can be done while the computer is not being used.

For more information or to download this software, visit
http://www.ibm.com/pc/us/desktop/lccm on the World Wide Web.

System Migration Assistant

System Migration Assistant (SMA) enables administrators to remotely transfer
configurations, profile settings, printer device drivers, and files from an IBM or
non-IBM computer to supported IBM systems.

For more information or to download this software, visit
http://www.pc.ibm.com/us/software/sysmgmt/products/sma on the World Wide Web.

Desktop Management Interface

DMI is a method for gathering information about the hardware and software in the
computer. In a network environment, network administrators can use DMI to
remotely monitor and control the computer.

Using security features

To deter unauthorized use of the computer, anti-intrusion and other security features
are provided with the computer.

Anti-intrusion features

IBM anti-intrusion features help protect against the theft of computer components,
such as the microprocessor, system memory modules, or hard disk drives.

A cover lock is built into the computer to prevent the cover from being removed.
Two identical keys for the cover lock are also supplied. A tag attached to the keys
has the key serial number and the address of the key manufacturer.

Note: Locksmiths are not authorized to duplicate the cover lock keys; you must

order replacement keys from the key manufacturer. When ordering
replacement keys, you will need the key code number.

You can also set a chassis-intrusion detector inside the computer to alert the
system administrator each time the computer cover is removed. For more
information about setting the chassis-intrusion alert, see “Configuration” on page 33.

If the computer uses the Alert on LAN feature and you are connected to a network
that uses Intel LANDesk
message is also sent to the network administrator console indicating that the
computer cover has been removed. For more information, see “Alert on LAN” on
page 13 and contact the network administrator.

Component protection

The components in the computer have serial numbers on them. You can register
the components with a third-party security company to improve the chances of
identifying the components if they are ever stolen and recovered. For more
information about component registration, see the IBM support page at
http://www.ibm.com/pc/us/desktop/assetid/ on the World Wide Web.

Data protection

You can lose data from the hard disk drive for a variety of reasons. Security
violations, viruses, or hard disk drive failures can all contribute to data loss. To help
protect against the loss of valuable information, IBM has incorporated a data-saving
feature into the computer.

IBM security solutions: IBM security solutions help keep electronic business

transactions safe. They include the following:

v Data protection
v Locked keyboard

SMART

hard disk drive: The computer comes with a SMART hard disk drive that

is enabled to report potential hard disk failures. If an error is detected, a
DMI-compliant warning message is sent to the computer screen and, if the
computer is part of a network, to an administrator console. When an error is
detected, the data on the hard disk can be backed up and the drive replaced.

SMART Reaction: To help back up important data, IBM provides SMART

Reaction

™

software on the computers with preinstalled software and also on the
IBM Software Selections CD. SMART Reaction is a client/server software
application that helps users and administrators respond effectively to a warning
issued by the SMART hard disk drive.

Virus protection: The computer has built-in virus protection that can be enabled

through the Configuration/Setup Utility program. This built-in protection only checks
for viruses in the boot record. Also, Norton AntiVirus for IBM is available on the IBM

Software Selections CD.

Locking the keyboard: You can lock the keyboard so that others are unable to

use it. If a user password is set, the keyboard is locked when you turn on the
computer. You must type the correct password before the keyboard will unlock. You
can enable the user password feature with the BIOS Setup Utility program. See

Setting Security Passwords in Access IBM.

Some operating systems have a keyboard and mouse lock-up feature. Refer to the

Diagnostics 25

IBM Enhanced Diagnostics

IBM provides programs that you can run to diagnose problems you suspect to be
hardware related. Several utility programs that provide helpful information about the
computer are also included. The user interface for running these diagnostic and
utility programs is provided by PC-Doctor for Windows.

The IBM Enhanced Diagnostics program will isolate the computer hardware from
software that was preinstalled (or that you have installed) on the hard disk drive.
The programs run independently of the operating system, and must be run either
from CD or diskette. This method of testing is generally used when other methods
are not accessible or have not been successful in isolating a problem suspected to
be hardware related.

The Device Driver and IBM Enhanced Diagnostics CD comes with the computer. To
run the IBM Enhanced Diagnostics program from the Device Driver and IBM

Enhanced Diagnostics CD, do the following:

1. Change the start up sequence for the computer. See “Changing the startup
sequence to start from the CD” on page 25.

System reliability considerations

To help ensure proper cooling and system reliability, make sure:

v Each of the drive bays has a filler panel installed.
v The cover is in place during normal operations, or is removed for no longer than

30 minutes while the computer is operating.

v There is space around the computer to allow the computer cooling system to

work properly. Leave about 127 mm (5 in.) of space around the front and rear of
the computer.

v Cables for optional adapters are routed according to the instructions provided

with the adapters.

v A failed fan is replaced within 48 hours.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and the system. To

avoid damage, keep static-sensitive devices in their static-protective packaging until
you are ready to install them.

To reduce the possibility of damage from an electrostatic discharge, observe the
following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the

device.

v While the device is still in its static-protective package, touch it to an unpainted

metal part of the computer for at least two seconds. (This discharges the static
electricity from the package and from your body).

v Remove the device from its package and install it directly into the computer

without setting it down. If it is necessary to set the device down, place it on its
static-protective package. (If the device is an adapter, place it component side
up). Do not place the device on the computer cover or on a metal table.

v Take additional care when handling devices during cold weather because heating

reduces indoor humidity and increases static electricity.

Working with adapters

You can install a variety of adapters in the expansion slots on the system board.
For help in locating the system board, see “Major components of the IntelliStation M
Pro Types 6850 and 6233” on page 41.

Note: The computer power supply might not be able to support the installation of

an adapter in all PCI slots. The ability of the power supply to support an
adapter in all slots is dependent on the computer configuration and the type
of PCI adapter installed.

You can install various adapters in the expansion slots in the computer. The AGP
Pro video adapter is installed in the AGP slot. Yo u can install up to five PCI
adapters in PCI expansion slots. There are three 32-bit PCI slots and two 64-bit
slots.

Note: Because of its width, the Wildcat III 6110 video adapter requires both the

AGP slot and the adjacent PCI slot. If your model contains this video
adapter, be careful when you install an adapter in PCI slot 2 because the
space between the Wildcat III 6110 adapter and PCI slot 2 is very limited,
which causes the adapters to be very close to each other.

Notes:

1. Install removable-media drives in bay 1.

2. The computer supports only one diskette drive (bay 3).

3. IDE models are shipped with an IDE hard disk drive in bay 5. If you upgrade,

install the second hard disk drive in bay 4.

4. The computer supports up to four IDE hard disk drives. Install the first two hard

disk drives in bay 4 and bay 5. Yo u can install two more hard disk drives in
bays 6 and 7 by removing the CD-ROM drive connection.

5. SCSI models are shipped with a SCSI hard disk drive in bay 9. If you upgrade,

install the next hard disk drive in bay 8; then, bays 7, 6, 5, and 4 (in this order).

Before you install hard disk drives in the computer, verify that you have all the
cables and other equipment specified in the documentation that comes with the
hard disk drive. You might also need to perform certain preinstallation activities.
Some of the steps are required only during the initial installation of an option.

SCSI Controller

The computer is equipped with a SCSI controller integrated on the system board for
use with Ultra160 SCSI devices.

If the computer has preinstalled software, you can find information about the SCSI
controller and connecting devices by clicking Start --> Access IBM--> Get help -->
View documentation. SCSI documentation is also on the Software Selections CD
that comes with the computer.

Power and signal cables for internal drives

The computer uses cables to connect internal drives to the power supply and
system board. The drives that are preinstalled in the 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. The following cables are provided:

v 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.

Installing options 53

v Flat signal cables, also called ribbon cables, connect SCSI, IDE, and diskette

drives to the system board.
– The wider gray signal cable has three connectors. One of these connectors

attaches to the CD-ROM drive, one is available for a device installed in bay 1,
and one attaches to the secondary IDE connector on the system board.

– The narrower gray signal cable has two connectors for attaching the diskette

drive to the diskette-drive connector on the system board.

– An Ultra160 twisted ribbon cable connects the internal Ultra160 SCSI hard

disk drive to the SCSI connector on the system board. This cable has five
additional connectors for attaching more internal SCSI devices.

– A round SCSI cable connects external SCSI devices to the SCSI connector on

the system board and provides an additional connector for a SCSI device
installed in bay 1. If a SCSI device is installed in bay 1 but no external SCSI
devices are attached, a SCSI terminator must be attached to the external
SCSI connector. For more information on connecting SCSI devices, see the
Adaptec SCSI documentation on the Software Selections CD that comes with
the computer.

To locate connectors on the system board, see “System board connectors”

Note:

on page 42.

Considerations

for cabling IDE internal drives: The following are some

important points to remember when connecting IDE internal drives:

v When you install a hard disk 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.

v IDE models ship with a gray ATA100 cable. Attach the blue connector to the

primary IDE connector on the system board, attach the black connector to the
master hard disk drive, and attach the gray connector to the subordinate hard
disk drive.

v If two IDE devices are used on a single cable, one must be designated as the

master device and the other as the subordinate device; otherwise, the system
might not recognize some of the IDE devices. Switch or jumper settings on each
IDE device determine the master or subordinate designation.

v 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.

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

Preinstallation steps

Before you install hard disk drives in the computer, verify that you have all the
cables and other equipment specified in the documentation that comes with the
hard disk drive. You might also need to perform certain preinstallation activities.
Some of the steps are required only during the initial installation of an option.

1. Read the “Safety information” on page 103, “Handling static-sensitive devices”
on page 43, and the documentation that comes with the drive.

2. Choose the bay in which you want to install the drive.

3. Check the instructions that come with the drive to see if you need to set any
switches or jumpers on the drive. If you are installing a SCSI device, be sure to
set the SCSI ID for that device.

Installing memory modules

Adding memory to the computer is an easy way to make programs run faster. You
can increase the amount of memory in the computer by installing options called
memory modules.

The computer has eight connectors for installing Rambus inline memory modules
(RIMMs). The IBM-installed RIMMs that come with the computer are ECC (error
checking and correction) RDRAM (Rambus dynamic random access memory)
modules.

RIMM pairing is as follows:

v Pair 1 includes RIMM 1 and RIMM 2.
v Pair 2 includes RIMM 3 and RIMM 4.
v Pair 3 includes RIMM 5 and RIMM 6.
v Pair 4 includes RIMM 7 and RIMM 8.

installing or replacing RIMMs, note the following:

When

v The memory board in the computer has eight RIMM connectors arranged in

pairs. RIMMs must be installed in matched pairs. This means that the RIMMs
installed in a RIMM connector pair must be the same speed, size, and
technology. For example, you can install a pair of 144Mbit, ECC, 400MHz, 128
MB RIMMs in RIMM 1 and RIMM 2 slots. You cannot install a pair that has one
144Mbit, ECC, 400MHz, 128 MB RIMM in RIMM 1 and one 288Mbit, ECC,
400MHz, 256 MB RIMM in RIMM 2, or vice versa. When you want to upgrade
with another pair of RIMMs, you can install either a pair of 128 MB RIMMs, a pair
of 256 MB RIMMs, or a pair of 512 MB RIMMs (as long as they are of the same
speed, size, and technologies).

v The memory board in the computer has eight RIMM connectors, pairs 1 and 2

must have RIMMs or continuity RIMMs (C-RIMMs) installed in them. For the
arrangement of the RIMM connector pairs on the computer memory board, see
the following table.

Refer to the following sequence examples for upgrading memory. For these
examples, we use 144Mbit, ECC, 400MHz, 128 MB, 256 MB, and 512 memory
modules:

Sequence 1

The computer is shipped with a pair of 128 MB RIMMs installed in RIMM
1 and RIMM 2 connectors and a pair of C-RIMMs installed in RIMM 3
and RIMM 4. All other RIMM connectors are empty.

Sequence 2

The first upgrade with a pair of 256 MB RIMMs. Remove the C-RIMMs
from RIMM 3 and RIMM 4 connectors, and insert them in RIMM 7 and
RIMM 8 connectors. Install the new pair of RIMMs in RIMM 3 and RIMM
4 connectors. RIMM 5 and RIMM 6 connectors remain empty.

Sequence 3

The second upgrade with a pair of 512 MB RIMMs. Remember, you can
mix and match memory modules as long as a pair is of the same size,
speed, and technology. Install the pair of 512 MB RIMMs in RIMM 5 and
RIMM 6 connectors. No other changes need to be made.

Sequence 4

The third upgrade with a pair of 128 MB RIMMs. Remove the C-RIMMs
from RIMM 7 and RIMM 8 (keep the C-RIMMs for future use). Install the
new pair of RIMMs into RIMM 7 and RIMM 8 connectors.

C-RIMMs (termination card) must be populated for unused RIMM slots within the

v

same paired channel.

v C-RIMMs are not needed if the RIMM connectors of the paired channel do not

populate any RIMMs.

v Install only ECC RIMMS to enable ECC.
v Do not mix RIMM speed, technologies, density, non-ECC and ECC memory

within a pair of RIMMs. This is not supported.

v RIMM connectors do not support dual inline memory modules (DIMMs).
v Use only PC800, 400 MHz RIMMs.

58 Hardware Maintenance Manual: IBM IntelliStation M Pro Type 6233 and 6850

Ethernet connector

The computer comes with an integrated Ethernet controller. This controller provides
an interface for connecting to 10-MBps or 100-MBps networks and provides
full-duplex capability, which enables simultaneous transmission and reception of
data on the Ethernet LAN.

To access the Ethernet connector, attach a Category 3, 4, or 5 unshielded
twisted-pair (UTP) cable to the RJ-45 connector on the rear of the computer. See
“Input/output connector locations” on page 66 for its location.

Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the

network be Category 5.

68 Hardware Maintenance Manual: IBM IntelliStation M Pro Type 6233 and 6850

69

Configuring the Ethernet controller

When you connect the computer to the network, the Ethernet controller
automatically detects the data-transfer rate (10 MBps or 100 MBps) on the network
and then sets the controller to operate at the appropriate rate. In addition, if the
Ethernet connector that the computer is connected to supports auto-negotiation, the
Ethernet controller will set the appropriate duplex state. That is, the Ethernet
controller will adjust to the network data rate, whether the data rate is standard
Ethernet (10BASE-T), Fast Ethernet (100BASE-TX), half duplex (HDX), or full
duplex (FDX). The controller supports HDX and FDX modes at both speeds.

The Ethernet controller is integrated on the system board. You do not need to set
any jumpers or configure the controller for the operating system before you use the
Ethernet controller. However, you must install a device driver to enable the
operating system to address the Ethernet controller. The device drivers are provided
on the preinstalled software and the Device Drivers and IBM Enhanced Diagnostics
CD.

Ethernet connector

There is an RJ-45 connector on the rear of the computer. See “Input/output
connector locations” on page 66 for the location of this connector.

Universal Serial Bus connectors

The computer has two Universal Serial Bus (USB) connectors, which are configured
automatically. USB is a serial interface standard for telephony and multimedia
devices. It uses Plug and Play technology to determine the type of device that is
attached to the connector.

Notes:

1. If you attach a standard (non-USB) keyboard to the keyboard connector, the
USB connectors and devices will be disabled during the power-on self-test.

2. If you install a USB keyboard that has a mouse connector, the USB keyboard
emulates a mouse, and you will not be able to disable the mouse settings in the
Configuration/Setup Utility program.

USB cables and hubs

You need a 4-pin cable to connect devices to USB 2 or USB 3. If you plan to attach
more than two USB devices, you must use a hub to connect the devices. The hub
provides multiple connectors for attaching additional external USB devices.

USB technology transfers data at up to 12 megabits-per-second (MBps) with a
maximum of 127 external devices and a maximum signal distance of five meters
(16 ft.) per segment.

depending on the option installed, you might need to update information in the
Configuration/Setup Utility program or install device drivers. For instructions on how
to install device drivers, see the instructions that come with the option. Some device
drivers are included on the Device Driver and IBM Enhanced Diagnostics CD that
comes with the computer.

Updating the computer configuration

Note: The configuration information in this section applies to installing options. For

more information on using the Configuration/Setup Utility program, see
“Using the Configuration/Setup Utility program” on page 33.

After adding options, you must update the configuration settings. In most cases,
system programs perform this configuration automatically. If the settings are not
updated automatically, you can use the Configuration/Setup Utility program to
reconfigure the appropriate settings. In either case, you must save the settings
before exiting from the Configuration/Setup Utility program.

For information on error messages from resource conflicts, see “Diagnostics” on
page 17 and “Symptom-to-FRU index” on page 83.

Configuring Plug and Play adapters

Adapters designed for PCI slots are Plug and Play devices. Plug and Play adapters
come with configuration specifications set in the operating system. These
specifications 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) code, which supports Plug and Play technology. If
the required resources are available, the BIOS code automatically configures the
adapter using resources not used by other devices. The system board of the
computer supports operating systems that use Plug and Play technology.

For more information on error messages from resource conflicts, see “Diagnostics”
on page 17 and “Symptom-to-FRU index” on page 83.

program menu (see “Using the Configuration/Setup Utility program” on page

33.

If the preceding message does not appear, use the Configuration/Setup Utility
program to configure the computer.

Configuring startup sequence

When the computer is turned on and after it completes loading the BIOS code and
performs POST, it looks for an operating system. The order in which it searches
devices for the operating system is determined by the primary startup sequence or
the automatic startup sequence. After adding new devices to the computer, you
might want to change the startup sequence. Yo u can use the Configuration/Setup
Utility program to configure startup devices.
