System and method for resetting a platform configuration register
WO 2003085498 A3
Abstract
A method and apparatus for resetting and modifying special registers in a security token is described. In one embodiment, a register may be reset when a reset flag is true when a special transmission on a bus demonstrates the mutual locality of the associated processor and chipset. A modify flag may also be used to indicate whether the register contents may be modified. Modifications may also be dependent upon demonstration of mutual locality.
