ABSTRACT:
A system that supports enhancement of device drivers written in distinct code sets, such as a 32-bit enhancement to a 16-bit existing driver is disclosed. The system defines a mechanism for the two device driver components to share information about their functioning, and for a device interface component to use that information so as to route calls to the device drivers based on their functional capabilities. The system can be implemented in a display device interface to support interaction between applications and video hardware components, which include enhanced device drivers.
