I am trying to get our ATT 386sx/EL computers to think that the A drive is the
B drive during boot up so that people can't boot off of the floppy.

I have been able to do this by switching cables and changing the setup so
the computer thinks it has a B drive.

the problem is that to get the B drive to become the A drive (this is done
so that novice users are not confused), we have to use the SUBST command from
DOS.  The problem arises in that there must be a diskette in the drive in order
to substitute it.  We have been able to get around the error which states there
is no diskette present but SUBST returns the error that the path is not found.  

Does anyone know how SUBST works so that we may write a psuedo command to
subst the B drive for the A drive?

advTHANKSance
