The system board's BIOS chip contains the system service tag number, which is also visible on a bar-code label on the bottom of the computer.
The replacement kit for the system board assembly includes a diskette or CD that provides a utility for transferring the service tag number to the replacement system board assembly.
Q NOTICE: If you received a flash BIOS update program diskette or CD with the replacement microprocessor, you must update the BIOS after replacing the microprocessor module. For instructions on updating or reflashing the BIOS, see the Dell Portable Computer BIOS Update Guide.
