摘要： Systems and methods of sharing files and data in memory between the two operating systems running on a computing device. A main operating system (OS) may execute on the computing device an provide numerous system features and functionality. To conserver power, the main OS may unload, or the computer may be reset, suspended or be shutdown. Prior to doing so, the main OS writes data to a known memory location that allows access by a secondary OS when the main OS is not present. The secondary OS provides a limited set of functionalities, while being able to use and interact with the data stored in the known memory location. Information about the data and permissions are stored in mailbox that is accessible to both operating system such that changes made when the secondary operating system is active are synchronized with the main operating system.
