Abstract
A computer system which assigns a unique identifier to each component in the system. The system includes a microprocessor, a memory, and one or more components. The microprocessor and the memory are coupled by first data lines. Each component has a storage device for storing data to uniquely identify each component and second data lines, the second data lines coupled to the first data lines. The storage device includes an identification input which is coupled to a selected one of the second data lines. The storage device in each component stores data from the selected one of the second data lines during the transmission of a sequence of data from the memory on the second data lines. With the system, a unique and consistent identifier can be assigned to each component in a computer system, each time the computer system is started. A separate memory device to store an identifier for each component is unnecessary.
