Introduction
Important Service Information
Important
Diskette fixes are customer installable.
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
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 symp-
toms 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 set-
tings. Note the current configuration settings (using
the View Configuration option) and verify that the set-
tings 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 dis-
played. 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
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.
