4.7.5. CPU ID Control Register Value

In Platform Designer, the automatically-assigned CPUID control register value is always 0x00000000, so Intel recommends always assigning the value manually.

To assign the value yourself, turn on Assign cpuid control register value manually and type a 32-bit value (in hexadecimal or decimal format) in the cpuid control register value box.
