ABSTRACT:
Methods for processing more securely. Embodiments provide effective and efficient mechanisms for reducing APIC interference with accesses to SMRAM, where enhanced SMM code implementing these mechanisms effectively reduces APIC attacks and increases the security of proprietary, confidential or otherwise secure data stored in SMRAM.
