Well, I guess that as far as basic DOS is concerned, you are right. But 
in the sense that these people are talking about, DOS should be able to 
see up to 65 (64MB). Check it out....from the dos prompt, type mem. 
Notice that the memory below 1mb is listed, and also all the memory above 
1 meg....what you can do with all that extra memory is another matter, 
but dos can see it.

Other OSs that can see 64megs, but no more are Win30, and 31. OS/2, Win95 
and WinNT versions below 3.50.

NT3.51 and I think 3.50 can see memory above 64megs. This all has to do 
with the way in which the O/S asks the systm how much memory there is. 
One of the Int15 functions I think, though I'm not sure of that.

There are some ways around this in dos/win31. If you use a good memory 
manager like QEMM, you can access the memroy above 64megs as EMS memory, 
but that is about it....The Shadow Knows...
