Eli, you recently said:

"DOS box" is actually a misnomer.  The technically correct term is
"Virtual Machine".  DJGPP programs always get their own virtual
machine (unless run directly by other DOS programs).  Some people
confuse "DOS box" as a synonym for "Virtual Machine" with "DOS box" as
the name of the window where COMMAND.COM is sitting at its prompt, and
I believe this is the source of the confusion expressed above.

end of quote.

I needed this. Thanks.

Now, would you state if it is true that it is possible to run in DOS on a 
Windows 95 and above machine WITH NO INTERFERENCE OR
INVOLVEMENT FROM Windows? I am about to put my DJGPP files
on a Windows 95 machine..

It is a fact that with Windows 3++ you can only have a clean memory
after bootup. Once you turn on Windows and back out of it memory
is contaminated and there is nothing you can do about it except re-boot.

Most of the time this is no problem, but with some sound and graphics
DOS code it raises hell.

Now, if you have to turn on a Windows95 machine INTO Windows95
(I am told you can only do it this way) and then go to DOS, isn't some
of the memory still held by Windows95?

I have my doubts that you can EVER have DOS with clean memory with
Windows 95. If I am wrong, I will be so happy to hear it.

Thanks for your expert info.

Ralph
