Abstract

A method and architecture for interfacing to a low level device driver in the user mode portion of an operating system having at least a user mode and a supervisor mode. The architecture includes a thin layer supervisor mode system interface driver (34) for presenting a complete interface to a user application (30) employing said low level device driver for executing user commands. The architecture also has a device routing driver portion also located in the supervisor portion of the operating system for routing between the thin layer supervisor mode system interface driver and the device driver (48, 72, 76) located in the user mode portion of the operating system. The device drivers typically require minimal to no modifications as a device driver wrapper emulates an API environment for the device driver. The device driver wrapper facilitates relinking of the device driver to the device driver wrapper without requiring recoding.
