Want microcode for cpuid 06fd rev=A1

Hey guys!
I want microcode for cpuid 06fd rev=A1 if anyone have it. Please note that rev=A1 is must or else will be useless for me. I downloaded microcode file from Intel's website but it is in ".dat" extension and I m unable to open it.
Also can someone please tell me how to open this ".dat" file.

Thanks
