    摘要: Embodiments of the invention are directed towards logic and/or modules stored in processor secure storage to determine whether a first platform firmware image (e.g., basic input/output system (BIOS), device read-only memory (ROM), manageability engine firmware) loaded onto a processor cache is valid. The processor executes the first platform firmware image if it is determined to be valid. If the first platform image is determined to be invalid, a second platform firmware image is located. If this platform firmware image is determined to be valid, the processor will execute said second platform image.In some embodiments of the invention, the determination of whether the first platform firmware image is valid is based, at least in part, on verification of a digital signature associated with the first platform firmware image. The digital signature may be created, for example, from a private key, wherein the digital signature is verified via a public key.
