Patent ID: 7702895

Claim:
A method for configuring a computing system having a central processing unit and a memory, comprising: packaging the central processing unit and the memory in a first housing, wherein the central processing unit accesses the memory to perform overall system functions of the computing system; packaging at least one subsystem of the computing system in a second housing separate from and external to said first housing, wherein said second housing has a predefined characteristic that visibly identifies a model of said at least one subsystem such that the model indicates compatibility with a particular type of central processing unit, wherein the at least one subsystem is designed to work together with the particular type of central processing unit; and connecting said central processing unit with said at least one subsystem with at least one communication link; wherein said central processing unit is interdependent with the at least one subsystem such that the central processing unit performs the overall system functions only when operatively connected to said at least one subsystem.
