Abstract
A method and system for modifying an identification associated with and stored internally in a computer system. Software can distinguish one computer system from another based upon an identification which is typically associated with the Central Processing Unit (CPU) of the computer system. Problems arise, however, when the CPU or other component containing the identification fail, and are replaced with components having a new identification. These problems are alleviated via the use of modifiable memory by the replacement component for storing its associated identification, and a modifying unit which can reside in the replacement component, operating system, or take the form of an application program. The modifying unit is invoked and passed an encrypted key value comprising the failed identification and the replacement identification. The modifying unit verifies that the current identification of the computer system matches that of the replacement identification, and then modifies the current identification to equal the failed identification.
