Computing device with redundant, dissimilar operating systems
First Claim
1. A method for minimizing the impact of computing device abnormalities, comprising:
- detecting a system abnormality while the computing device is operating under control of a first operating system executed by a first processor system; and
transferring control of the computing device to a second operating system executed by a second processor system in response to detection of the system abnormality, wherein the second operating system is different than the first operating system.

Abstract
The adverse impact of system abnormalities, such as crashes or other failures or problems, is minimized by switching control of a computing device from a first operating system to a second operating system in the event a system abnormality is detected. For example, if a system abnormality causes a processor system under control of the first operating system to crash, another processor system under control of a second operating system can take over. An application program that was executing under control of the first operating system when the crash or other abnormality occurred can continue functioning under control of the second operating system.

13. A computing device for minimizing the impact of system abnormalities, comprising:
-
a first processor system having a first operating system; a second processor system having a second operating system, wherein control of the computing device is transferred from the first processor system operating under control of the first operating system to the second processor system operating under control of the second operating system in response to detection of a system abnormality, wherein the second operating system is different from the first operating system. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
