US Patent 7558072 Adapter module

An adapter module is described. The adapter module includes a circuit board, a first socket and an adapter device. One face of the first socket is electrically connected to the circuit board on the first face of the circuit. The other face of the first socket connects to a first central processing unit (CPU). One face of the adapter base is electrically connected to the circuit board on the second face of the circuit board. The other face of the adapter base connects to a second socket. The circuit board sends signals from the second socket, through the adapter base and the first socket, to the first CPU. When the adapter base is not connected to the second socket, the second socket is capable of connecting to a second kind of CPU.
