Installing a Kernel-Mode Multimedia Driver
If you list your kernel-mode driver in your oemsetup.inf file, the Multimedia applet installs it for you by calling the Win32 CreateService function. For more information about oemsetup.inf files, see Using oemsetup.inf Files with Multimedia Drivers.
Additionally, the user-mode driver can install the kernel-mode driver by either calling CreateService, or by calling one of the functions in the driver support libraries. These libraries are described in the chapters discussing the various driver types. The chapters are listed in Types of Multimedia Devices.
