There's more than one way.  The simplest method is to the the program
call "MASTER CREATE" on the DOS 3.3 system master disk, assuming, of course,
that you have access to the disk.  This program will re-write DOS 3.3 to
disk tracks 0-2.  Since that is where the boot-up program's name is stored,
rewriting these tracks will fix the problem.

Another method, for the courageous, is to use a sector editor to change the
name, but I don't recall the exact sector number offhand; it's somewhere on
track 2.

I also have a program I wrote which saves the current image of DOS in memory
out to disk.  I don't have it handy right now, or I'd post it.  I use it
to change boot names AND the filetype of the boot program (A, B, T).  In fact,
it was originally written to combat several Apple ][+ viruses running around
my old high school (released by a rather un-benign acquaintance..).

If you need any more info, let me know. (I don't have any reference sources
handy at the moment to give you all the details...)
