The big difference there though is that with dv you're going to end up with a
first "window" that's going to become progressively smaller as you load more
drivers,  as even though you can load many of them into high memory they each
tend to need a small bit of that lower 640k,  eating away at it until you
start bumping into that limit.  On this box it's showing 571k as being
available (the most you can stuff into that first window,  successive ones
will be smaller) even though I've only got two processes currently running on
a machine with 16M.

The reason for this is because as good as dv is,  it's still running on top of 
_dos_.  OS/2 gets beyond all that,  and isn't restricted to a dos way of
dealing with memory.

Yes.  I understand the concern you're expressing here.  But under OS/2,  it's
not a problem...
