Method and system for performing pre-boot operations from an external memory including memory address and geometry

摘要

A system for booting a computing device with a windowing operating system obtained from an external memory media via an external interface includes an initialization module stored in a read-only memory in the computing device, the module being executed in a processor in the computing device and establishing a data connection to the external memory media through the external interface, and an external device in which the external memory media is disposed, the media storing a windowing operating system image at an external location, and sending the image from the media to the computing device via the external interface in response to a request from the computing device based on memory geometry information of the media, the image being received by the computing device, loaded into a runtime memory in the computing device and then executed by the processor to boot the windowing operating system in the computing device.
