The message means that emTeX (386) is not a DPMI compliant program, which
is a convention about how memory hungry DOS programs get and manage the
"unconventional" memory they need. Thus, Windows will not let it run in
the DOS box. There are two solutions;
(1) Run it in native DOS.
(2) If you must have a fast 32-bit TeX in a multi-tasking envirornment,
    run it under OS/2 in an OS/2 window. If I have got this right, the
    same executable should run in an OS/2 window. If I goofed, I know
    there is a 386 TeX for OS/2. Either way you are covered. Note that
    you will not be able to run the program in the DOS box under OS/2
    for the same reason, but that is irrelevant.

I'm afraid your simultaneous quest for multi-tasking and a fast, free
TeX means you'll have to switch OS's. In my opinion its well worth it.
