Abstract
A system and method for concurrently operating multiple operating system environments on a hardware platform. A dominant personality server is provided to control basic system configuration and resources. Subdominant servers are provided to support applications for other operating systems. Binary compatibility is supported for each dominant and subdominant operating system personality. Personality neutral services are extracted from each operating system environment and coalesced in personality neutral servers. Interprocess communications are implemented using defined object oriented and procedural interfaces. Server response and conflict resolution are handled by the dominant personality neutral server. Any supported operating system can be the dominant server by selection of the operator.
