Interesting. What video card did you say you had again? How much RAM does
it have?

Maybe, although I have a feeling it doesn't even attempt to swap it
anywhere on my computer. Maybe it's bold enough to at least swap it to
another location in video memory, but that seems dangerous to me. I'll
certainly have to try it again if I ever get a new video card =)

Actually, I haven't been having a whole lot of trouble with it lately. I
just have to make sure my CPU fan never stops, and for some reason I
don't get the "it is now safe to turn off your computer" prompt when i do
a shutdown (which I sometimes do as a quick way to get to DOS, since that
screen is really just a hidden DOS prompt =)

>people say (although it's not nearly as stable as Unix, of course).

Of course =) It would be nice if there was a good OS for PC's that used
pre-emptive multitasking and only an optional GUI, yet would run MSDOS
(and I suppose maybe Windoze) programs.
