Dual Environment Computing System and Method and System for Providing a Dual Environment Computing System

A method for operating a dual computing environment to a computer system, the dual computing environment comprising a first and second computing environment, at least one of which is stored in a hibernated state, method comprising:

• causing the computing system to switch, during a hibernate and resume operation, from an active one of the first and second computing environments to the hibernated one of the first and second computing environments and whereby the active one of the first and second computing environments is placed in a hibernated state and the hibernated one of the first and second computing environments is placed in an active state.

A system for providing a dual computing environment to a computer system having a data storage device, the dual computing environment comprising:

• a first computing environment and a second computer environment, at least one of which is stored in hibernated state in the data storage device,
• computer readable media encoding computer program code configured, when executed from within one of the first and second computing environments, to cause hibernation of the respective first or second computing environment from within which the code was executed and resuming, from the hibernated state of the other of the first and second computing environments.
