I have discovered (thru experimentation) that the DPMI
version of 4F07 requires you to pre-cook the values
stored in cx and dx.  Instead of being x & y coordinates,
cx is a linear address into a memory bank, and dx is the
actual memory bank you want to address. (Each
bank is 64K on my card).
So, by adding some extra logic to convert screen
x & y coordinates, I can now continue using
protected mode banking... Joy!!!
