I don't think so.  When you choose Shutdown, it closes all (or trys to) the
applications and windows it can find and then saves the cache to disk and
then displays a nifty little dialog that says you can now turn off your
machine safely.  When you choose to use duel boot and go to DOS, it prepares
the disk but doesn't bother closing anything.  At least that is the way
I understand it.  Please correct me if I am wrong.

To boot to DOS, I use a utility called MBOOT that was in the last issue of
PC Magazine.  When you start up your machine, it gives you a choice to boot
up under DOS or OS/2.
