Abstract
A firmware recovery system includes a baseboard management controller (BMC) module, a south bridge, a basic input and output system (BIOS) module, a multiplexer and a storage module. The BIOS module is connected to the BMC module by the south bridge and determines whether a firmware file of the BMC module is corrupt. The multiplexer selectively connects the BIOS module or the BMC module to the south bridge. The storage module stores a new firmware file. When the firmware file of the BMC module is corrupt, the BIOS module controls the multiplexer to select the BMC module to connect to the south bridge. The BIOS module reads the new firmware file from the storage module to recover the corrupt firmware file from the BMC module.
