Abstract: A system and method for automatic recovery of a firmware image is disclosed. The method can include creating a shadow firmware image in a storage device from a firmware image in non-volatile memory. It is determined whether an abnormal event affecting the firmware image has occurred. The shadow firmware image is recovered from the storage device. The shadow firmware image is copied to the non-volatile memory.
