Well, I wouldn't let it stop you from trying.  Only DEC can really explain
how they derive this number, but my interpretations is that "bootable" is
a misnomer and what they are really giving is the amount of memory needed
to adequately run the system software witout allowances for applications
coding and multiple users.  There are hard limits having to do with the
size of the generic kernel, system utilities and swapping considerations,
however I doubt these add up to 6 MB.

You should ought to consider picking up some more memory so you can run
or not run DECwindows as a matter of preference rather than necessity...
