ABSTRACT In a computer system that has one or more primary processing units processing user tasks and at least one auxiliary processing unit servicing the primary process- ing units, feature control is performed by storing a authorization code in the auxiliary processing unit. When an operation to change the feature of the computer system is initiated, a signal, including a key code, is sent to the auxiliary processing unit. The auxiliary processing unit checks the key code against the author- ization code, and enables the operation if the check is successful.
