Patent ID: 7370189

Claim:
A system comprising: a processor; a tamper resistant storage element to store information regarding one or more operating points of an adjustable operating parameter for the processor; an element to determine what the current processor operating point is of the operating parameter after the operating parameter has reached a stable state; an element to compare the current operating point with the stored information; and wherein the processor is: to determine in connection with a secure boot of the processor what the operating point is of the operating parameter after the operating parameter reaches a stable state; to determine if the operating point is acceptable by comparing the operating point with information that is stored in the tamper resistant storage element; and enabled to proceed with the secure boot only if the operating point was determined to be acceptable, wherein if the operating point for this operating parameter was determined to be unacceptable, then adjusting the operating parameter to a second operating point that is based on the information stored in the tamper resistant storage element.
