ClassPnP

Summary

This is the library for all storage drivers. It simplifies writing a storage driver by implementing 90 percent of the code required to support Plug and Play, Power Management, et cetera. This library is used by disk.sys, cdrom.sys and the tape class drivers.

No INF file is needed to install this library.

Building the Sample

To build the sample, run build. Once built, one binary will be created: classpnp.sys. This sample is based on live source code, and only builds in the current OS build environment.
