Electronic device and method for verifying firmware of the electronic device
View Patent ↗In a method for verifying firmware of an electronic device, the electronic device includes a baseboard management controller (BMC) for storing a BMC firmware, and a basic input-output system (BIOS) for storing a BIOS firmware. The method writes a first verification code into the BMC firmware, and writes a second verification code into the BIOS firmware. The method writes the BMC firmware into the BMC, and writes the BIOS firmware into the BIOS. The method further triggers the electronic device to power off if the first verification code of the BMC firmware is not identical to the second verification code of the BIOS firmware, and boots an operating system of the electronic device if the first verification code of the BMC firmware is identical to the second verification code of the BIOS firmware.
