Its not a matter of how much memory the PC can see. That is ussually a
charactaristic of the Chipset, and or the number of simms on the PC
itself. Like the origianl Plato had four simm sockets, for up to
128megs, but the Neptune chipset could and can see 256megs.

The real limiting factor is the way in which DOS and some older
versions of WinNT asked the system how much memory it has.

I guess that I was mistaken about WIN95...which is a very welcome
suprise. I still can't figure out how Microsoft got off its collectve
backsides and fixed something like that.  Of course who would have
thought a couple years ago that we would be having this little
talk...about how limiting DOS is that it can limit ONLY 64megs...

hmph....  The Shadow Knows...
