SUMMARY
If the CPUs in your computer are not all at the same stepping level, Windows writes an informational message to the Event log. When this occurs, you do not receive an error message on the screen.



MORE INFORMATION
The information written to the Event log is similar to the sample text below. In the following sample, events 6005 and 6009 indicate that the event log has been started and the revision of Windows 2000 that is in use. The third entry exists if the CPU stepping levels are mismatched. Generally, this is not a problem. But, it is recommended that you contact the OEM (Orginal Equipment Manufacturer) for specific recommendations on operating in a mixed stepping environment. - Event ID Count Component   Message sample - I 6005    2   EventLog     The Event log service was started.

Should problems occur with this system, contact the CPU manufacturer to see if this mix of processors is supported.
