Abstract
A method and an apparatus for validating a processor firmware (“PF”) are disclosed. In one embodiment, at least one version of Processor Firmware (“PF”) is identified. After identification, the PF is compared with a version of PF that is required by a processor, to determine whether the PF is compatible with the processor. If the version of PF is incompatible with the version of PF required by the processor, the current execution is suspended and a new version of PF is obtained. When the new version of PF is received, the system is initialized.
