This first minimal driver must be manually loaded. It does not touch any hardware, but instead creates an internal device name (MINIMAL0) and a symbolic link name (MIN1). It consists of a single source module, Driver.cpp. A header file, Driver.h, declares driver-specific information about our nonhardware device, such as the DEVICE_EXTENSION.

DRIVERENTRY
