		problems occur with older non ACPI operating systems.
Max CPUID Value	Disabled	When enabled, the processor will limit the maximum
Limit	Enabled	CPUID input value to 03h when queried, even if the
		processor supports a higher CPUID input value. When
		disabled, the processor will return the actual maximum
		CPUID input value of the processor when queried.
		Limiting the CPUID input value may be required for older
		operating systems that cannot handle the extra CPUID
		information returned when using the full CPUID input
		value.
Execute Disable Bit	Disabled	Enable or disable the hardware support for data execution
