    							Introduction
    Important service information
    ImportantBIOS and device driver fixes are
    customer-installable. The BIOS and device drivers
    are posted on the IBM support site
    http://www.ibm.com/pc/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.
    Attention:The 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.
    Attention:The 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:

    driveDiskette

    							Safety notices: multilingual translations
    In this manual, safety notices appear in English with a
    page number reference to the appropriate multi-lingual,
    translated safety notice found in this section.
    The following safety notices are provided in English,
    French, German, Italian, and Spanish languages.
    Safety notice 1
    Before 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 ciò
    scuotendo 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 eléctricos.

    DANGER
    Some standby batteries contain a small amount of
    nickel and cadmium. Do not disassemble a standby
    battery, recharge it, throw it into fire or water, or
    short-circuit it. Dispose of the battery as required
    by local ordinances or regulations. Use only the
    battery in the appropriate parts listing. Use of an
    incorrect battery can result in ignition or explosion
    of the battery.
    Certaines batteries de secours contiennent du
    nickel et du cadmium. Ne les démontez pas, ne les
    rechargez pas, ne les exposez ni au feu ni à l’eau.
    Ne les mettez pas en court-circuit. Pour les mettre
    au rebut, conformez-vous à la réglementation en
    vigueur. Lorsque vous remplacez la pile de
    sauvegarde ou celle de l’horloge temps réel, veillez
    à n’utiliser que les modèles cités dans la liste de
    pièces détachées adéquate. Une batterie ou une
    pile inappropriée risque de prendre feu ou
    d’exploser.
    Die Bereitschaftsbatterie, die sich unter dem
    Diskettenlaufwerk befindet, kann geringe Mengen
    Nickel und Cadmium enthalten. Sie darf nur durch
    die Verkaufsstelle oder den IBM Kundendienst
    ausgetauscht werden. Sie darf nicht zerlegt,
    wiederaufgeladen, kurzgeschlossen, oder Feuer
    oder Wasser ausgesetzt werden. Die Batterie kann
    schwere Verbrennungen oder Verätzungen
    verursachen. Bei der Entsorgung die örtlichen
    Bestimmungen für Sondermüll beachten. Beim
    Ersetzen der Bereitschafts-oder Systembatterie nur
    Batterien des Typs verwenden, der in der
    Ersatzteilliste aufgeführt ist. Der Einsatz falscher
    Batterien kann zu Entzündung oder Explosion
    führen.
