Sorry to bother you once again.

Did you mean that CWSDPMI will be able to obtain about 500Mb out of
768Mb (in my case) in true DOS, or that things might crash if I have
more that 500Mb of physical RAM?  I assume you meant the former, that I
will only be able to use 500Mb and the rest will lie dormant.

On those Windows switches:  do you have a link to some extra info,
perchance, or should I just start searching?

Thanks,
Dave W.
