Diagnostics and test information

The following tools are available to help identify and resolve hardware-related problems:

 Power-on self-test (POST)  POST Beep Codes  Error Code Format  IBM PC Enhanced Diagnostics

Power-on self-test (POST)

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

self-test

, or

POST

. POST does the following:

 Checks some basic system-board operations  Checks the memory operation  Starts the video operation  Verifies that the diskette drive is working  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 your operating system or application program appears.

Note

Type 6268/6278/6288/6338/2173 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:

1. Enable Power on Status in setup. See “Setup Utility program” on page 41.

power-on

If the POST detects a problem, an error message appears on your 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.

POST beep codes

The Power On Self-Test generates a beeping sound to indicate successful completion of POST or to indicate that the tests detect an error.

One beep and the appearance of text on the display indicates successful completion of the POST. More than one beep indicates that the POST detects an error.

32 IBM PC 300/IntelliStation/Aptiva Vol 2 HMM

Note

Type 6268/6278/6288/6338/2173 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:

1. Enable Power on Status in setup. See “Setup Utility program” on page 41.

Error code format

This section provides an explanation of the encoded non-SCSI and SCSI POST error codes.

Error messages are displayed on the screen as three, four, five, eight, twelve, or thirteen digits. An “X” in an error message can be any number or letter. The shorter POST errors are highlighted in the Symptom-to-FRU Index. Some digits will represent different information for SCSI errors versus non-SCSI errors.

The following figure shows which digits display the shorter POST errors. The figure also defines additional SCSI information.

Replacing a system board

Notes

1. The BIOS and Vital Product Data (VPD) for the computer you are servicing must be 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 “BIOS levels” on page 54 “Vital

product data” on page 50, and “Flash (BIOS/VPD) update procedure” on page 55.

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. If you are instructed to replace the system board, do the following.

4. Remove the processor from the old system board and install it on the new system board.

5. Remove any of the following installed options on the old system board, and install them on the new system board.  Memory modules

6. Ensure that the new system board jumper settings match the old system board jumper settings.

7. 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.

Security features

Security features in this section include:  Passwords

 Vital Product Data  Management Information Format (MIF)  Alert on LAN

Passwords

The following provides information about computer hardware and software-related passwords:

 Power-on Password  Administrator Password

 Operating System Password

Power-on and Administrator passwords are set in the Setup Utility program. See “Setup Utility program” on page 41 for information about running the Setup Utility.

48 IBM PC 300/IntelliStation/Aptiva Vol 2 HMM

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 do the following:

Note

On some models, this procedure will also remove the administrator password.

1. Unplug the power cord and remove the top cover.

2. Refer to “System board layout” on page 77 to find the password jumper.

3. Move the password jumper to connect the center pin and the pin on the opposite end of the connector.

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.

PC 300 - 6268/6278/6288/6338 Aptiva - 2173

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 6268, 6278, 6288/6338, 2173 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 Utility program” on page 41

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 procedure” on page 55.

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 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.

50 IBM PC 300/IntelliStation/Aptiva Vol 2 HMM

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.

To update the EPROM using the DMI MIF Browser:

1. Click Start from the desktop, then Programs.

2. Select IBM SystemView Agent.

3. Select 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:

 Computer disconnected from the network  Computer unplugged from the power outlet  All POST errors  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.

Symptom-to-FRU index

The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed first. Always begin with “General checkout” on page 24. See “IBM PC Enhanced Diagnostics error codes” on page 1 when running diagnostics. This index can also be used to help you decide which FRUs to have available when servicing a computer. If you are unable to correct the problem using this index, go to “Undetermined problem” on page 102.

Notes

 If you have both an error message and an

incorrect audio response, diagnose the error message first.

 If you cannot run the diagnostic tests or you get

a diagnostic error code when running a test, but did receive a POST error message, diagnose the POST error message first.

 If you did not receive any error message, look for

a description of your error symptoms in the first part of this index.

 Check all power supply voltages before you

replace the system board. (See “Power supply” on page 29.)

 Check the hard disk drive jumper settings before

you replace a hard disk drive. (See “Hard disk drive jumper settings” on page 52.)

Important

1. Some errors are indicated with a series of beep codes. (See “Beep symptoms” on page 81.)

Type 6268/6278/6288/6338/2173 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:

 Enable Power on Status in setup. See

“Setup Utility program” on page 41.

2. The processor is a separate FRU from the system board; the processor is not included with the system board FRU.
