							Introduction
Important service information
ImportantDiskette fixes are customer-installable. The diskette
fixes are posted on the IBM support site
(http://www.pc.ibm.com/support/).
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.
Strategy for replacing FRUs
Before replacing partsMake sure that all diskette fixes are installed before
replacing any FRUs listed in this manual.
Use the following strategy to prevent unnecessary FRU
replacement and service expense:
vIf you are instructed to replace a FRU but the
replacement does not correct the problem, reinstall
the original FRU before you continue.
vSome 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 replacing one
of them does not correct the problem, reinstall that
board, and then replace the other one.
vIf an adapter or device consists of more than one FRU,
any of the FRUs may be the cause of the error. 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.

							AttentionThe setup configuration on the computer you are
servicing may have been customized. Running
Automatic Configuration may alter the settings. Note
the current configuration settings (using the View
Configuration option); then, when service has been
completed, verify that those settings remain in
effect.
Strategy for replacing a hard-disk driveAlways try to run a low-level format before replacing a
hard-disk drive.
AttentionThe drive startup sequence in the computer you are
servicing may have been changed. Be extremely
careful during write operations such as copying,
saving, or formatting. If you select an incorrect drive,
data or programs can be overwritten.
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. Whatever causes the
first error code may also cause false error codes. 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.
Diskette compatibility matrix
The compatibility of each of the drives with the diskettes
for it is as follows:

Safety notice 1Before the computer is powered-on after FRU
replacement, make sure all screws, springs, and
other small parts are in place and are not left loose
inside the computer. Verify this by shaking the
computer and listening for rattling sounds. Metallic
parts or metal flakes can cause electrical shorts.
Avant de remettre l’ordinateur sous tension après
remplacement d’une unitéen clientèle, vérifiez que
tous les ressorts, vis et autres pièces sont bien en
place et bien fixées. Pour ce faire, secouez l’unitéet
assurez-vous qu’aucun bruit suspect ne se produit.
Des pièces métalliques ou des copeaux de métal
pourraient causer un court-circuit.
Bevor nach einem FRU-Austausch der Computer
wieder angeschlossen wird, mußsichergestellt
werden, daßkeine Schrauben, Federn oder andere
Kleinteile fehlen oder im Gehäuse vergessen
wurden. Der Computer mußgeschüttelt und auf
Klappergeräusche geprüft werden. Metallteile
oder-splitter können Kurzschlüsse erzeugen.
Prima di accendere l’elaboratore dopo cheéstata
effettuata la sostituzione di una FRU, accertarsi che
tutte le viti, le molle e tutte le altri parti di piccole
dimensioni siano nella corretta posizione e non
siano sparse all’interno dell’elaboratore. Verificare ci
ÚÚscuotendo l’elaboratore e prestando attenzione
ad eventuali rumori; eventuali parti o pezzetti
metallici possono provocare cortocircuiti pericolosi.
Antes de encender el sistema despues de sustituir
una FRU, compruebe que todos los tornillos,
muelles y demás piezas pequeñas se encuentran
en su sitio y no se encuentran sueltas dentro del
sistema. Compruébelo agitando el sistema y
escuchando los posibles ruidos que provocarían.
Las piezas metálicas pueden causar cortocircuitos
