1. A method of enabling a computer system to run programs written for two different operating systems comprising:
- executing a first operating system;
storing information about the current state of the first operating system to enable reinitialization;
executing a second operating system; and
reinitializing the first operating system using said stored information.

Abstract
An operating system may be more efficiently initiated and restarted by making a virtual image of the configuration settings for a base system configuration. These settings may be stored and may be used to quickly initiate the system in its base configuration, for example, using an executive. The base configuration may be automatically modified in response to system hardware or software configuration changes. These changes may be stored with the base configuration information. When a crash occurs, the virtual image may be used to quickly restore the system without the necessity for rebooting the operating system.
