UINT32 MSR_IA32_BIOS_SIGN_ID_REGISTER::MicrocodeUpdateSignature

[Bits 63:32] Microcode update signature. This field contains the signature of the currently loaded microcode update when read following the execution of the CPUID instruction, function 1. It is required that this register field be pre-loaded with zero prior to executing the CPUID, function 1. If the field remains equal to zero, then there is no microcode update loaded. Another nonzero value will be the signature.
