Now running on a new /unix, with a number of modifications.

The boot board from the 45 is now on the 44, which means that (at long
last!) we can dispense with lengthy typed-in boots for the disk and
tape.  Revised boot instructions will be posted shortly; the old ones
still work in a pinch.  The board is at 771000-771777.

The kernel memory-allocation stuff has been altered to deal properly
with >2MB of memory, which will probably be a reality here soon.  We
could test it right now, actually -- we have a total of 2.25MB of 44
memory on hand, although we're running with a bit under 2 right now --
but the gain doesn't seem worth fiddling with the boards, especially
when we'll probably have to do it again soon for another 1MB board.

The DH driver has been modified to permit running lines as both dialin
and dialout.  This stuff doesn't work.  We don't know why yet, although
I have a kernel dump which should tell us after a bit of analysis.  For
the moment, 5121 is still dialout-only via Wern's breakout box.

A new "device" driver has been installed:  /dev/prf is the user interface
to a kernel profiler, somewhat similar to the one in System V.  It seems
to work, although we'll need to be up for a while before it really tells
us anything useful.  Documentation is coming.

We have also done some minor cleanup chores, and removed the Star Ring
driver since Star Ring interfacing is being left to the 05s.
