    Quite honestly, I feel a little sorry for DOS4.01.  It gets a lot of 
flack from people who really don't use it.  The kernal for 4.01 is only some
15k greater than the 3.3 kernal.  With 3.3 and a few tsrs, you can get up 
to about 580k free.  4.01 has a few feature 3.3 doesn't such as the MEM 
command.

    QEMM can give up to 590k free (600,000 or so bytes), and will not load the
kernal into High Memory.  It is a little testy, and creates a lot of problems

    I have been looking at the Beta test version of MS DOS 5.0, and it gives
some 639,500bytes free on the machine I looked at.  Of course, this has to be
a 386, and requires more than 1MB.

    DR DOS is out now legally, and works quite similar to DOS5.  You
might want to check it out.  However, when DOS 5.00 comes out, I will buy 
and make my 386 happy.
