ABSTRACT:
A data processing system includes a main memory system which couples in common with a central processing unit to a bus for transfer of data between the central processing unit and memory system. The memory system includes a plurality of memory controllers, each of which controls the operation of a number of memory modules. Each controller also includes reconfiguration apparatus for enabling reconfiguration of the memory system upon detection of a fault. The reconfiguration apparatus includes apparatus for identifying the type and design revision of the controller associated therewith enabling more expeditious fault diagnosis based upon status signals provided by the controller during diagnostic testing by the central processing unit.
