Introduction

Important

Diskette fixes are customer installable. The diskette

fixes are located on the PC Company Bulletin Board

Service (BBS). The direct phone line for modem

connection is 919-557-0001 or tieline 255-0001.

Advise customers to contact the PC Company

HelpCenter at 800-772-2227 if they need assistance in

obtaining or installing any diskette fixes.

Customers in Canada should call IBM HelpPC at

800-565-3344 for assistance or down-load information.

The Canadian BBS phone numbers are:

Montreal 514-938-3022

Toronto 905-316-4255

Vancouver 604-664-6464

Winnipeg 204-934-2735

FRU Replacement Strategy

Ensure that all diskette fixes are installed prior to replacing

any FRUs. And, use the following strategy to prevent

unnecessary FRU replacement and service expense:

If you are instructed to replace a FRU and that

does not correct the problem, reinstall the original

FRU before you continue.

Some computers have both a processor board and a

system board. If you are instructed to replace either

the processor board or the system board, and the first

board that you replaced does not correct the problem,

reinstall the original board, then replace the other

(processor or system) board.

If an adapter or device consists of more than one

FRU, an error code may be caused by any of the

FRUs. Before replacing the adapter or device,

remove the FRUs, one by one, to see if the

symptoms change. Replace only the FRU that

changed the symptoms.

Attention

A customized setup configuration (other than default

settings) may exist on the computer you are servicing.

Running Automatic Configuration may alter those

settings. Note the current configuration settings (using

the View Configuration option) and verify that the

settings are in place when service is complete.

The advanced diagnostic tests are intended to test

only

IBM products. Non-IBM products or modified options can

give false errors and invalid responses.

Hard Disk Drive Replacement Strategy:

Always try to run a low-level format before replacing a hard

disk drive.

Attention

The drive startup sequence in the computer you are

servicing might have been 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.

How to Use Error Messages

Use the error codes displayed on the screen to diagnose

failures. If more than one error code is displayed, begin

the diagnosis with the first error code. The cause of the

first error code can result in false error codes being

displayed. If no error code is displayed, see if the error

symptom is listed in the Symptom-to-FRU Index for the

computer you are servicing.

How to Read POST Error Messages

POST error messages are displayed on the screen as

three, four, five, or eight digits. The error messages that

can be displayed as shorter POST messages are

highlighted in this index. Some digits will represent

different information for SCSI errors versus non-SCSI

errors.

The following example shows which digits display the

shorter POST error messages and also defines the SCSI

information in an eight-digit error message.

Shorter POST Messages

┌────┬────┬────┬────┐

│ │ │ │ │

┌────┬────┬────┬────┬────┬────┬────┬────┐

│ ð│ ð│ ð│ ð│ ð│ ð│ ð│ ð│

└────┴────┴────┴────┴────┴────┴────┴────┘

│ │ │ │ │ │ │ │

Reserved ││││││Size (SCSI)

└────┴────┘ │ │ Slot Number (SCSI)

Device Code │ Logical Unit Number (SCSI)

ID (SCSI)

All SCSI devices are set to a different SCSI ID.

Duplicate SCSI ID settings can generate a false error

message. Use the SCSI ID to determine whether the error

message is coming from an internal or an external device.
