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 operat-

ing systems. If you are using an operating system other than Windows, this problem

may occur. To avoid this problem, enable this field to limit the return value to 3 or less

than 3

Enabled for Windows XP
