Abstract
At power on of a computing device, a baseboard management controller (BMC) of the computing device executes, a first-stage bootloader program to download a second-stage bootloader program from a first server. The BMC executes the second-stage bootloader program to download third-stage firmware of the BMC from a second server. The BMC executes the third-stage firmware to download firmware of a primary processing subsystem of the computing device from a third server, and to start the primary processing subsystem by causing the primary processing subsystem to execute the firmware of the primary processing subsystem.
