Zusammenfassung:A method, apparatus, and computer instructions in a data processing system for managing clocks. The functionality of clock sources in the data processing system is verified to identify a set of valid clock sources in response to beginning an initial load process. Hardware is initialized in the data processing system using a valid clock source from the set of valid clock sources.
