What about the secret "MAGIC MODE"?   For those who don't know about
this mode, it is something AT&T has for those who need a "shell" off
a floppy /unix.   Boot the foundation disk #1 (yes, the first disk)
and get to the part that asks..

	1) Full Restore
	2) Partial Restore
	3) ...

And at the prompt that is asking you to enter the particular option,
type "magic mode<CR>"  You will then get:

Poof!

And added to the prompt is ..

Enter [ ... shell] 

You type "shell" and you get a "#", / being the floppy.  Of course there
isn't too many things on that floppy (enough to get yourself going) but
you should mount your "HARD DISK" using the (fsys(1M) command).  I don't
remember the exact syntax, it's been a while... but I think it's:

	# fsys -m /dev/dsk/c1d0s0 

Or something to that effect... and to unmount (don't forget this) use
the "-u" option.  But this will get you started anyhow.
