installed on the new system board (FRU) after it is installed in the computer. To do
this, you must run the Flash Update program using the Flash Update diskette. See
2. Always ensure the latest level of BIOS is installed on the computer. A down level BIOS
may cause false errors and unnecessary replacement of the system board.
3. The processor is a separate FRU from the system board and is not included with the
system board FRU.
4. If the new system board does not correct the problem, reinstall the options on the old
system board, reinstall the old system board, then replace the processor.
To replace the system board, do the following:
2. Remove the 7 screws that attach the system board to the chassis.
3. Remove the board from the chassis.

POST error codes
Each time you power-on the system, it performs a series of tests that check the
operation of the system and some options. This series of tests is called the
Power-On Self-Test, or POST. POST does the following operations.
v Checks some basic system-board operations
v Checks the memory operation
v Starts the video operation
v Verifies that the diskette drive is working
v Verifies that the hard disk drive is working
If the POST finishes without detecting any problems, a single beep sounds and the
first screen of the operating system or application program appears.
Note:
Type 2271/6840/6841 computers default to come up quiet (no beep and no memory count
and checkpoint code display) when no errors are detected by POST.
To enable beep and memory count and checkpoint code display when a successful POST
occurs, do the following:
2. Set Power-On Self-Test to Enhanced.
If the POST detects a problem, an error message appears on the screen. A single
problem can cause several error messages to appear. When you correct the cause of
the first error message, the other error messages probably will not appear on the
screen the next time you turn on the system.
In the following index, X can represent any number.

Security features
Security features in this section include the following:
v Passwords
v Vital Product Data
v Management Information Format (MIF)
v Alert on LAN
Passwords
The following section provides information about computer hardware and
software-related passwords.
v Power-on Password
v Administrator Password
v Operating System Password
Power-on and Administrator passwords are set in the Setup Utility program. See
Power-on password
A power-on password denies access to the computer by an unauthorized user
when the computer is powered on. When a power-on password is active, the
password prompt appears on the screen each time the computer is powered on.
The computer starts after the proper password is entered.
Removing a power-on password
To service a computer with an active and unknown power-on password, power-off
the computer and use the following procedure.
Note: On some models, this procedure will also remove the administrator password.
1. Unplug the power cord and remove the top cover.
recovery jumper.
3. Move the recovery jumper from normal to clear.
4. Power-on the computer. The system senses the change in the position and
erases the password. It is necessary to move the jumper back to the previous position.
5. Remind the user to enter a new password when service is complete.
94 Hardware Maintenance Manual
Administrator password
The administrator password is used to restrict access to the Configuration/Setup
Utility program. If the administrator password is activated, and you do not enter
the administrator password, the configuration can be viewed but not changed.
Note:
Type 2251/6830/6831 has Enhanced Security Mode. If Enhanced Security mode is enabled
and there is no password given, the computer will act as if Enhanced Security is disabled.
If Enhanced Security is Enabled and an administrator password is given, the administrator
password must be entered to use the computer. If the administrator password is lost or
forgotten, the system board in the computer must be replaced in order to regain access to
the Configuration/Setup Utility program.
Administrator password control
Operating system password
An operating system password is very similar to a power-on password and denies
access to the computer by an unauthorized user when the password is activated.
The computer is unusable until the password is entered and recognized by the
computer.
Vital product data
Each computer has a unique Vital Product Data (VPD) code stored in the
nonvolatile memory on the system board. After you replace the system board, the
Management Information Format (MIF)
Management Information Format (MIF) is a file used to maintain a list of the
system unit serial number along with all serialized components (for example,
system board, riser card, memory, and processor).
At the time of computer manufacture, the EPROM will be loaded with the serial
numbers of the system and all major components. The customer will have access to
the MIF file via the DMI MIF Browser that is installed with the preload and is also
available on the SSCD that is provided with the system.
A company called Retain-a-Group is a central data warehouse offering serial
number data management. Retain-a-Group acts as a focal point to law
enforcement. The customer has the option to purchase serial number information
and services from Retain-a-Group. It is the customer’s responsibility to maintain
the MIF file and to inform Retain-a-Group of any changes to the file.
Some customers may request their servicers to assist them in maintaining the MIF
file when serialized components are replaced during hardware service. This
assistance is between the customer and the servicer. The servicer can use the DMI
MIF Browser to update the MIF information in the EPROM. It is anticipated that
some servicers might charge for this service.
Chapter 8. Additional Service Information 95
To update the EPROM using the DMI MIF Browser, use the following procedure.
1. Click Start from the desktop, then Programs.
2. Select IBM SystemView Agent
3. Select the Serial Number Information icon
4. Click the plus sign to expand.
5. Select the component you want to view or edit.
6. Double click on the component you want to change.
7. Enter new data in the Value field, then click Apply.
Alert on LAN
Alert on LAN provides notification of changes in the computer, even when the
computer power is turned off. Working with DMI and Wake on LAN«
technologies, Alert on LAN helps to manage and monitor the hardware and
software features of the computer. Alert on LAN generates notifications to the
server of these occurrences:
v Computer disconnected from the network
v Computer unplugged from the power outlet
v All POST errors
v Operating system or POST hang condition
Alert on LAN events are configured to be Enabled or Disabled from the LAN
server only, and not from the computer. See the LAN administrator for
configuration status information.

a soft material that does not insulate you when working with live electrical currents.
Many customers have, near their equipment, rubber floor mats that contain small
conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect
yourself from electrical shock.
128 Hardware Maintenance Manual
Observe the following rules when working on electrical equipment.
v Find the room emergency power-off (EPO) switch, disconnecting switch, or
electrical outlet. If an electrical accident occurs, you can then operate the switch
or unplug the power cord quickly.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
v Before you start to work on the machine, unplug the power cord. If you cannot
unplug it, ask the customer to power-off the wall box that supplies power to the
machine and to lock the wall box in the off position.
v If you need to work on a machine that has exposed electrical circuits, observe the
following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Remember: Another person must be there to switch off the power, if
necessary.
– Use only one hand when working with powered-on electrical equipment;
keep the other hand in your pocket or behind your back.
Remember: There must be a complete circuit to cause electrical shock. By
observing the above rule, you may prevent a current from passing through
your body.
– When using testers, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you
from grounds such as metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages;
these instructions are in the safety sections of maintenance information. Use
extreme care when measuring high voltages.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition.
v Do not use worn or broken tools and testers.
v Never assume that power has been disconnected from a circuit. First, check that it
has been powered-off.
v Always look carefully for possible hazards in your work area. Examples of these
hazards are moist floors, nongrounded power extension cables, power surges,
and missing safety grounds.
v Do not touch live electrical circuits with the reflective surface of a plastic dental
mirror. The surface is conductive; such touching can cause personal injury and
machine damage.
Chapter 9. Related Service Information 129
v Do not service the following parts (or similar units) with the power on when they
are removed from their normal operating places in a machine. This practice
ensures correct grounding of the units.)
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
v If an electrical accident occurs:
– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.
Handling electrostatic discharge-sensitive devices
Any computer part containing transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD). ESD damage can occur when
there is a difference in charge between objects. Protect against ESD damage by
equalizing the charge so that the machine, the part, the work mat, and the person
handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements
noted here.
2. Make sure that the ESD protective devices you use have been certified (ISO
9000) as fully effective.
Use the following precautions when handling ESD-sensitive parts.
v Keep the parts in protective packages until they are inserted into the product.
v Avoid contact with other people.
v Wear a grounded wrist strap against your skin to eliminate static on your body.
v Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
v Select a grounding system, such as those listed below, to provide protection that
meets the specific service requirement.
Note: The use of a grounding system is desirable but not required to protect
against ESD damage.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire
ground.
– Use an ESD common ground or reference point when working on a
double-insulated or battery-operated system. You can use coax or
connector-outside shells on these systems.
– Use the round ground-prong of the ac plug on ac-operated computers.
v Use the black side of a grounded work mat to provide a static-free work surface.
The mat is especially useful when handling ESD-sensitive devices.

Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially unsafe
conditions on these products. Each machine, as it was designed and built, had
required safety items installed to protect users and service personnel from injury.
This guide addresses only those items. However, good judgment should be used to
identify potential safety hazards due to attachment of non-IBM features or options
not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent
hazard could be and whether you can continue without first correcting the
problem.
Consider these conditions and the safety hazards they present:
v Electrical hazards, especially primary power (primary voltage on the frame can
cause serious or fatal electrical shock).
v Explosive hazards, such as a damaged CRT face or bulging capacitor
v Mechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. Begin the following
checks with the power off, and the power cord disconnected.
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Power-off the computer. Disconnect the power cord.
3. Check the power cord for the following:
a. A third-wire ground connector in good condition. Use a meter to measure
third-wire ground continuity for 0.1 ohm or less between the external
ground pin and frame ground.
b. The power cord should be the appropriate type as specified in the parts
listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6. Check inside the unit for any obvious unsafe conditions, such as metal filings,
contamination, water or other liquids, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been
removed or tampered with.

Problem determination tips
Because there is a large variety of hardware and software combinations that can be
encountered, use the following information to assist you in problem determination.
As you go through problem determination, consider these questions.
v Do diagnostics fail?
v What, when, where, single, or multiple systems?
v Is the failure repeatable?
v Has this configuration ever worked?
v If it has been working, what changes were made prior to it failing?
v Is this the original reported failure?
Important:
To eliminate confusion, systems are considered identical only if the following are exactly
identical for each system:
1. Machine type and model
2. BIOS level
3. Adapters/attachments (in same locations)
4. Address jumpers/terminators/cabling
5. Software versions and levels
6. Reference/Diagnostics Diskette
7. Configuration options set in the system
8. Setup for operation system control files
Comparing the configuration and software setup between “working” and “non-working”
systems will often resolve problems.
File updates
Use the World Wide Web (WWW) to download Diagnostic, BIOS Flash, and Device
Driver files.
To download NetVista file, do the following:
v Go to http://www.ibm.com/.
v Select Support.
v Select Desktop computing from the ″Search by Category″ pull-down menu.
v Select NetVista from the ″Product Family″ list.
v Search for the machine type in the ″Quick Path″ box on the left.
v Select the appropriate file type from the ″Downloadable files by Category″
pull-down menu or go directly to the link from the ″Downloadable files by date″
list.
132 Hardware Maintenance Manual
Adding adapters to the system
When adapters are added to the system, an area in memory has to be allocated to
run its programs. This can be done with either hardware switches or software
mapping.
If there is a conflict in software mapping, then the following may be true.
v The first device to attach to an IRQ, DMA, I/O Address, or RAM location will
probably function. The second device will not be found.
v Standalone diagnostics might function properly because the device that was
found is the only device running.
Software configuration conflicts occur when the following are true.
v Hardware has a different configuration than the software that is using it expects.
v Hardware memory address space is in conflict with memory used by the
application software.
Software considerations
Suspect a software failure if one of the following is true.
v Hardware diagnostics run error-free.
v Swapping hardware components fails to isolate the problem.
A software problem might be the result of a mismatch between the hardware and
the operating system device drivers or direct drivers.
BIOS
The BIOS acts as an interface between the system hardware, application software,
and the operating system.
The BIOS contains the instructions to operate the basic system components:
v Keyboard
v Serial and parallel ports
v Diskette drive
v Hard disk drive
v VGA display
v Clock
v Memory controller.
The BIOS then starts the IPL or Boot functions.
Drivers
Device drivers are the BIOS for additional hardware. They are the communicators
of the hardware assignments to the operating system, including the following:
v IRQ level
v DMA channel
v I/O address
v ROM or RAM.
Some device drivers like HIMEM.SYS are position sensitive and must be placed
before other device drivers in the CONFIG.SYS file.
Chapter 9. Related Service Information 133
Not all device drivers are found in the CONFIG.SYS file. Advanced operating
systems use .INI files to set up and start devices.
Device drivers can access the hardware in five ways.
v Operating system direct to hardware using a direct driver
Direct drivers, which bypass BIOS, have the advantage of faster throughput, but
the disadvantage of limited error-handling capability and reduced software and
hardware compatibility and flexibility. This method is not used in the IBM PC
Series systems.
v Operating system to BIOS to hardware
This is the recommended way. It’s the most flexible because it is independent of
the hardware.
v Applications to operating system to BIOS to hardware
This method is inflexible and is dependent on the operating system.
v Applications to BIOS to hardware
This method has some flexibility but it is dependent on the BIOS.
v Applications to hardware
This method is dependent on the hardware and is very inflexible. However, it is
very fast, very efficient, and it has no overhead.
Hardware considerations
Use the following tools to help identify and resolve hardware-related problems.
v Power-on self-test (POST)
v POST Beep codes
v Test programs
v Error messages
POST does the following operations.
v Checks some basic system board operations
v Checks the memory operation
v Starts the video operation
v Verifies that the diskette drive is working
v Verifies that the hard disk drive is working
Use the test programs that come with this HMM or with the system you are
servicing to test the IBM components of the system and some external devices.
Also, from the DOS prompt or from OS/2 Utilities, use the CHKDSK command to
check and repair hard disk data allocation errors.
Error messages generated by the software (the operating system or application
programs), generally are text messages. However, error messages can be text,
numeric, or both text and numeric.
Any time there is an error message indicating a problem with the system, follow
the General Checkout procedures in this HMM to resolve the problem.
Basically, there are five types of error messages.
v POST error messages are displayed when the POST finds problems with the
hardware or detects a change in the hardware configuration.
134 Hardware Maintenance Manual
v POST Beep codes are sounds emitted from the speaker if the POST finds a
problem. One beep indicates that the POST completed successfully. Multiple
beeps indicate a problem was found.
v Diagnostic error messages are displayed when a test program finds a problem
with a hardware component.
v Software-generated error messages are displayed 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 the
v Multiple messages occur when the first error causes additional errors. Follow
the suggested action of the first error displayed.
System resource conflicts
System failures occur when there are system resource conflicts with the following:
v Interrupt Request Queue (IRQ)
v Direct Memory Access (DMA)
v I/O Address
v ROM and RAM Addresses.
IRQ
v Assigns a unique interrupt request line to every I/O device (line numbers range
from 0 to 15).
v Interrupts the processor to force it to service the request.
v Handles interrupts on a priority basis (low numbers have the highest priority).
v Queues interrupt request.
IRQ conflicts occur when there are multiple assignments to the same interrupt
level. If there is an IRQ conflict, the system will hang. Use the systems diagnostics
to check for multiple assignments to the same interrupt level before replacing any
hardware component.
DMA
v Accesses the memory by bypassing the processor. This allows the processor
more time for applications and programs.
v Accesses memory directly from the serial and parallel ports on some systems.
v Accesses memory directly from some adapters using a DMA channel. This
allows the adapter to operate faster.
v Provides from 4 to 15 DMA channels. The number varies depending on the
system.
If multiple assignments of the same DMA channel occur, the system will hang.
Use the system diagnostics to check for multiple assignments to the same DMA
channel before replacing any hardware components.
I/O address
A unique I/O address is assigned to each system component.
If multiple assignments of the same I/O address occur, the system will hang. Use
the DOS MEM command to check for multiple assignments to the same I/O
address before replacing any hardware component.
Chapter 9. Related Service Information 135
ROM and RAM Addresses
Adapter cards with processors can contain RAM and ROM. If the adapter cards
have onboard memory, then the following are true.
v ROM contains operating instructions for the adapter I/O.
v RAM is used for buffering.
Two adapters using the same memory area will cause a failure. This failure might
appear as a hardware failure.
The IRQ levels, DMA channels, I/O address, and ROM and RAM addresses all
become potential conflicts and system problems. When conflicts arise, they might
show up as system hangs, lost or missing devices, incorrect or bad data, or failing
diagnostics. Always eliminate conflicts in these areas before replacing any
hardware components.
