Zusammenfassung:	A computer system is rebooted after updating a boot image without running platform firmware with its power-on self-test of system hardware devices and without retrieving all of the modules included in a boot image from an external source and reloading them into system memory. The reboot process includes the steps of loading one or more updated modules of the boot image into the system memory, executing the boot loader module to load for execution modules of the boot image including a system software kernel and the updated modules, and transferring execution control to the system software kernel.
