Step 3: Add VDD Communication Code

Implement the function ResetHiResMode which is used by the Windows 95 VDD to cause the video hardware to be reinitialized after returning to Windows from a full-screen MS-DOS session.

Drivers must register the address of ResetHiResMode with the Windows 95 VDD module by calling the VDD function VDD_DRIVER_REGISTER. Subsequently, every time that the user switches to a full-screen MS-DOS session, ResetHiResMode is called to do the work.
