ABSTRACT:
A method for interfacing an operating system extension with a personal computer includes the step of providing a function command to the operating system of the personal computer when the operating system extension performs a function typically performed by the operating system of the personal computer. The operating system of the personal computer responds to the function command to perform functions unique to the operating system of the personal computer so that the application program will execute properly. As an example, when an application program is being loaded by an operating system extension, the operating system of the personal computer responds to the function command by revising the application program so that the application program will be compatible with the personal computer.
