To create a virtual device, you need to: 1:Read the chapter in this manual that describes the virtual device for your type of hardware devie. 2:Write the required control procedures, virtual device services, and API functions. 3:Create a module-definition file that identifies the appropriate module name for your virtual device, and exports the required device description block. 4:Assemble and link your device. 5:Test your virtual device using the debugging version of Windows 95. For information about debugging virtual devices, see. 6:Create an installation file (*.INF) for your virtual device and related files. You install a virtual device by specifying settings for the registry and copying files to the Windows SYSTEM or related directories. 7:Create your final distribution disk or disks.
