Abstract

Methods and apparatus are provided for electronically configuring hardware features and options. A computer chip encoding method is provided in which a predetermined code or encryption sequence is uniquely associated with a computer chip. This code is used to modify a hardware configuration by enabling new features or options. The systems and methods reduce manufacturing and inventory costs by allowing a generic product to be produced which is then customized to meet the needs of the user. In addition, features and options of a data processing system can be dynamically upgraded without interruption of service or hardware replacement.
