When you are sure the MAKEFILE matches your build environment and the VxD will have the name you want, you can build your VxD. To build a retail version of your VxD, change the current directory to the DDK subdirectory and then enter the command
nmake retail 
 To build a debug version of your VxD, change the current directory to the DDK subdirectory and then enter the command
    nmake debug 
 You can also build a debug version by simply using the command
    nmake
 To build both a retail and debug version, use the command
    nmake all
