Module Name:

    hwcomp.h

Abstract:

    This file declares the interface for hardware compatibility code.
    This includes the routines that build hwcomp.dat (the NT PNP ID
    list), that compare the hardware on Win9x to what is supported by
    NT, that enumerate the Win9x devices, and that manage the Have Disk
    capability for drivers.

Author:

    Jim Schmidt (jimschm) 06-Jul-1996

Revision History:

    jimschm     09-Jan-1998     Work on hwcomp.dat rebuild detection
    jimschm     11-Nov-1997     Have Disk capability, online detection
    jimschm     09-Oct-1997     Revised to use project's APIs
