No-beep symptoms  
Important:  
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:  
1. Select Start Options in the Configuration/Setup Utility program (see Setup Utility  
2. Set Power-On Self-Test to Enhanced.  
Symptom/Error

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:  
1. Select Start Options in the Configuration/Setup Utility program (see Setup Utility  
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.

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  
Setup Utility programon page 8 for information about running the Setup Utility.  
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.

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  
The Administrator password is set in the Setup Configuration. Refer to Setup  
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  
VPD must be updated. To update the VPD, see Flash (BIOS/VPD) update  
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 customers 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.

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.

customers personnel are not in a hazardous position.  
v Place removed covers and other parts in a safe place, away from all personnel,  
while you are servicing the machine.  
v Keep your tool case away from walk areas so that other people will not trip over  
it.  
v Do not wear loose clothing that can be trapped in the moving parts of a  
machine. Ensure that your sleeves are fastened or rolled up above your elbows.  
If your hair is long, fasten it.  
v Insert the ends of your necktie or scarf inside clothing or fasten it with a  
nonconductive clip, approximately 8 centimeters (3 inches) from the end.  
v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your  
clothing. Remember: Metal objects are good electrical conductors.  
v Wear safety glasses when you are doing any of the following: hammering,  
drilling soldering, cutting wire, attaching springs, using solvents, or working in  
any other conditions that might be hazardous to your eyes.  
v After service, reinstall all safety shields, guards, labels, and ground wires.  
Replace any safety device that is worn or defective.

Use only approved tools and test equipment. Some hand tools have handles covered with  
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.

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.

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.  
v Verify any recent hardware changes. See Hardware considerationson page  
v Verify any recent software changes. See Software considerationson page 133.  
v Verify that the BIOS is at the latest level. See BIOSon page 133.  
v Verify that the drivers are at the latest levels. See Driverson page 133.  
v Verify that the Configuration matches the hardware. See System resource  
v Verify that the Diagnostics diskette is at the latest level. See File updates.  
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 workingand 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 Categorypull-down menu.  
v Select NetVista from the Product Familylist.  
v Search for the machine type in the Quick Pathbox 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.

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  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
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. Its 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  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
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  
installed software package. Also, refer to Software considerationson page 133.  
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.

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.
