It would seem that the components not loaded in conventional memory would
have to be loaded in high memory or in the UMB area, thereby crowding out
other stuff you might want otherwise to load in those locations.

Thanks for the tip. I didn't know about that one.

Didn't know about that one either.

It is no complicated matter for anyone to simply type the three letter word
"WIN" on a line in AUTOEXEC.BAT. That is how it is done with WINDOWS 3.x.

That problem is there with any scenario where you are trying to access a
a partition > 32MB with DOS 3.30. DOS 3.31 is capable of accessing a 100MB
partition, and perhaps larger. I don't the specs. on the limitations of
DOS 3.31.
Thanks for your reply. I have just learned a couple of really good tips
from you.
All the best,
