Introduction

Important Service Information

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 con-

nection 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 download 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

Before Replacing Parts

Ensure that all diskette fixes are installed prior to

replacing any FRUs listed in this manual.

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 ser-

vicing. Running Automatic Configuration may alter those

Introduction 1

settings. Note the current configuration settings (using the

View Configuration option) and verify that the settings are

in place when service is complete.

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 over-written 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 high-

lighted 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 informa-

tion in an eight-digit error message.

POST

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.
