The internal error (IERR) signal on Intel microprocessors (CPU's) can be triggered by a number of external events in addition to an Internal CPU Error. An algorithm and methodology is disclosed here that filters IERR events so that unnecessary replacement of CPU devices can be avoided and the actual causes of the event can be isolated.
