SYSTEM AND METHOD FOR TRANSFERRING DATA BETWEEN OPERATING SYSTEMS

摘要

Mechanisms for moving data between different operating systems in a dual OS computing device are discussed. More particularly, embodiments of the present invention utilize the clipboard facilities supported by the operating systems, along with firmware and helper software in each OS, to move data back and forth when switching between an active and inactive operating system. The clipboard contents are preserved in non-volatile storage that is not lost across the sleep-state transitions used to switch operating systems. Helper software analyzes the clipboard contents being copied and converts them into a format recognized by the current operating system and its applications.

1. A computer-implemented method for copying data between an active and inactive operating system (OS) in a dual-OS computing device, comprising:
identifying an initiation of a switch of operating systems in the computing device from an active first OS to an inactive second OS; copying data from a clipboard available to the first OS to a non-volatile storage location based on the identifying of the initiation of the switch, the copying of the data to the non-volatile storage location performed by a first agent operating while the first OS is active before the switch; performing the switch of the operating systems using a sleep-state transition so that the first OS becomes inactive and the second OS becomes active; copying data while the second OS is becoming active from the non-volatile storage location to a clipboard available to the second OS, the copying of the data to the clipboard available to the second OS performed by a second agent.
