32-bit version of Windows Visa Business is OK after DPMI limit is increased by adding
corresponding registry key. One problem with it is available DOS memory amount.
With Win98SE one can use QEMM or something similar to get most of stuff out of
first 640K. Largest amount I remember was 634K (I was long time ago, so the value
may be not completely accurate, but it was on that order)
