摘要: An object-oriented framework contains program code for booting a processor with volatile storage from an attached non-volatile storage. The provides hardware independent boot image base class which can be subclassed to provide each specific configuration. performs low level tasks such as determining the configuration and loading kernel into memory. Once has been loaded memory it is initialized using information hardware-independent platform. Further non-subclassable used establish support accessing shared libraries in Finally environment established by instantiating file object libraries.
