The BIOS chip on the system board contains the service tag sequence, which is also visible on a bar code label on the bottom of the computer.
The replacement kit for the system board includes a floppy disk or CD that provides a utility for transferring the service tag sequence to the replacement system board.
NOTICE: If you received a flash BIOS update program floppy disk or CD with
the replacement microprocessor, you must update the BIOS after replacing the
microprocessor module.
First remove the network cable cover: Insert a narrow plastic scribe
or small screwdriver just barely into the slot that faces the back of
the computer (do not insert the scribe far enough to catch on the
wires inside), press down on the cover lightly to secure it, and pry
upward to release the cover.
