Abstract

See full text

An information handling system includes a memory and a baseboard management controller. The memory includes a recovery partition including a recovery kernel, a first boot partition including first firmware, and a second boot partition including backup firmware. The baseboard management controller (BMC) attempts a first boot operation of the first firmware in the first boot partition. In response to a failure of the first boot operation, the BMC attempts a second boot operation of the backup firmware in the second boot partition. In response to a failure of the second boot operation, the BMC operates a recovery kernel. During the operation of the recovery kernel, the BMC provides a firmware request to an enclosure controller, receives blocks of correct firmware from a functioning baseboard management controller, stores the blocks of correct firmware in the first boot partition, attempts and completes a third boot operation of the correct firmware.
