Limit CPUID Maximum
The CPUID instruction of some newer CPUs will return a value greater
than 3. The default is Disabled because this problem does not exist in
the Windows series operating systems. If you are using an operating system
other than Windows, this problem may occur. To avoid this problem, you
enable this field to limit the return value to 3 or lesser than 3.
