Abstract:
A mapping table is passed to system software upon loading of the system software in a computer system. The mapping table is generated from a user-defined configuration file and maps device identifiers of various devices implemented in the computer system, as assigned by the device manufacturers, to device identifiers that are recognizable by the system software. The mapping is used by the system software when it performs binding of device drivers to devices so that devices that have been given generic and sometimes obscure names by the device manufacturers can still be associated with and bound to device drivers loaded by the system software.
