Abstract
An electronic device includes an internal storage module, a baseboard management controller (BMC) and a port. The internal storage module stores a first firmware and a boot application. The port connects to an external storage for storing a second firmware which is a backup of the first firmware. After the electronic device is powered on, the BMC runs the boot application to load the first firmware from the internal storage module. If the first firmware fails to load, the BMC copies the second firmware from the external storage to the internal storage module to replace the first firmware.
Claims14
An electronic device comprising:
- an internal storage module for storing a first firmware and a boot application;
- a baseboard management controller (BMC);
- and
- a port for connecting an external storage which stores a second firmware which is a backup of the first firmware;
- wherein when receiving power after the electronic device is powered on, the BMC runs the boot application to load the first firmware from the internal storage module, if the first firmware fails to load, the BMC copies the second firmware from the external storage to the internal storage module to replace the first firmware.
A method for loading firmware of a BMC of an electronic device, comprising:
- storing a first firmware and a boot application in an internal storage module;
- storing a second firmware which is a backup of the first firmware in an external storage which is connected to a port of the electronic device;
- running the boot application to load the first firmware from the internal storage module;
- and
- copying the second firmware from the external storage to the internal storage module to replace the first firmware if the first firmware is failure to be loaded.
