Abstract

This article describes a system for improving the usability of computing devices during the boot phase. By utilizing a fast booting operating system with a limited number of available applications it is possible to make the computer usable quickly whilst continuing to boot a more comprehensive operating system in the background. A novel aspect of this is the ability to transparently access and modify the state of an application running in the first operating system from within the second. This allows in-progress state, such as a half-written email, to be completed from within either operating system. If the enhanced features of the comprehensive operating system are no longer needed it can be shutdown to save power without interrupting the applications running in the original operating system.

A method of dual booting with transfer from a limited operating system to the usual operating system

Typically booting a portable computer system into an operating system (e.g. Windows, Linux, OSX) takes a significant amount of time. It is desirable to have instant-on to reduce wait time and increase productivity. Current solutions to this problem are to offer dual-boot options on portable computers, for example, booting into an entertainment system mode that provides a DVD player and a web browser, but does not boot the normal operating system. The limitation of this approach is that whilst the user is able to perform a few tasks in this mode, a boot into the normal operating system is still required if the user needs to perform other tasks.

    The basic idea presented here is to use any of i) additional embedded hardware, ii) an external device (e.g. a smartphone), or iii) a virtual partition of the portable computer's hardware to boot a limited instant-on operating system that provides access to, for example, e-mail and web browsing. The difference between this approach and the existing systems is that the normal operating system is able to boot in the background while the user interacts with the limited operating system. A key feature of the invention is the ability to transfer the contents of the limited operating system to windows and processes in the normal operating system, providing the user with a seamless transition when the normal operating system is ready. This is achieved because the two operating systems run concurrently, but the application itself runs only in the OS where it started. The application output is originally provided to the faster booting OS, therefore allowing a quicker start to doing something useful. Later when the second OS has finished bo...
