Abstract
A technique for quickly switching between a first operating system (OS) and a second OS involves deactivating the first OS and booting the second OS from memory. The technique can include inserting a context switching layer between the first OS and a hardware layer to facilitate context switching. It may be desirable to allocate memory for the second OS and preserve state of the first OS before deactivating the first OS and booting the second OS from memory.
