I've been reading the docs, info, and DPMI specs. I also have read the 
mail archives in order to understand why we must use near or far pointers
to gain access to the video buffer.  

I don't understand why we can't use a function such as 
dpmi_segment_to_descriptor to map this to a linear address without
the disadvantages of the 'fat ds' method.  What am I missing here??
This is supposed to give a 64k block, which is just the size of the 
buffer in memory. 

Thanks for clueing me in!!
