|1||The processor CPUID signature value of the processor that mismatched.|
|2||The expected microcode revision for the processor.|
|3||The actual, reported microcode revision for the processor.|
|4||The processor index of the mismatching processor.|
One or more processors in the multiprocessor configuration have inconsistent microcode loaded. This bugcheck indicates that faulty system firmware has mistakenly applied a microcode update to only a subset of processors in the host configuration. System firmware must apply microcode updates to all processors in a uniform fashion.
