Safety Notice 8
Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, then disconnect any interconnecting cables.
Avant de retirer une unité remplaçable en clientèle, mettez le système hors tension, débranchez tous les cordons d'alimentation des socles de prise de courant, retirez la batterie et déconnectez tous les cordons d'interface.
Die Stromzufuhr muß abgeschaltet, alle Stromkabel aus der Steckdose gezogen, der Akku entfernt und alle Verbindungskabel abgenommen sein, bevor eine FRU entfernt wird.
Prima di rimuovere qualsiasi FRU, spegnere il sistema, scollegare dalle prese elettriche tutti i cavi di alimentazione, rimuovere la batteria e poi scollegare i cavi di interconnessione.
Antes de quitar una FRU, apague el sistema, desenchufe todos los cables de las tomas de corriente eléctrica, quite la batería y, a continuación, desconecte cualquier cable de conexión entre dispositivos.
Safety Notice 1
Before the computer is powered-on after FRU replacement, make sure all screws, springs, or 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 unité en clientèle, vérifiez que tous les ressorts, vis et autres pièces sont bien en place et bien fixées. Pour ce faire, secouez l'unité et 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, muß sichergestellt werden, daß keine Schrauben, Federn oder andere Kleinteile fehlen oder im Gehäuse vergessen wurden. Der Computer muß geschüttelt und auf Klappergeräusche geprüft werden. Metallteile oder -splitter können Kurzschlüsse erzeugen.
Prima di accendere l'elaboratore dopo che é stata 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 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.

The PREP utility initializes and prepares the hard disk surface for the storage of data. It performs a low-level format, then checks for bad sectors. If any bad sectors are found, they are marked in a way that prevents data from being stored in them.
There are two situations where PREP is used.
PREP erases all data on the hard disk.
If at all possible, always back up the data on the hard disk to diskettes before running PREP.
To use the advanced utilities, select Advanced Utilities from the Run Tests menu. Use the arrow keys to move the highlight to the proper utility. Instructions are provided on the screens when the utilities are selected.
Read LAN ID
Select this field to read the current LAN ID number that is programmed into the main board.
Set LAN ID
Select this field to program a new LAN ID number into the main board.
Set EEPROM
Select this field to program the EEPROM. It allows you to set LCD display type (monochrome or color) and enable or disable the LAN option, if installed.
Note: Always operate the computer on AC power when updating the BIOS.
Use this procedure to reprogram the computer's BIOS. The computer contains the latest version of BIOS available when manufactured, but later revisions might be available. There are two reasons for replacing the BIOS.
After you select this option, the current BIOS version will be displayed. You will be asked if you want to overwrite the current BIOS version. If you answer Yes, the computer will look for the BIOS image file on drive A and install it.
NOTE: Always operate the computer on AC power when updating the BIOS.
Use the chart to match the size and shape of the screws in the computer you are servicing.
