ABSTRACT:
A method of communication between a device driver and a system kernel uses a standardized generic data structure which facilitates communication of numeric limitations as well as flags. In addition, device-specific extensions may be added to the data structure to permit communication of new types of information concerning devices without sacrificing standardization. Device drivers store device capability information in the data structures during system startup, and the system kernel reads the information prior to performing an I/O request.
