This parameter indicates whether this DIVE instance
should be using the physical display hardware. If fNonScreenInstance
is FALSE, this function returns a pointer to the linear base address
to the VRAM and the DiveBlitImage functions
in this instance can have screen or non-screen destination buffers. If
fNonScreenInstance is TRUE, the DIVE instance will not use display
hardware resources, and only non-screen destination buffers can be used
as destination buffers for DiveBlitImage.
