FYI -- I thought you might me interested in general on what Isaac has
to say.  You see, while the ZCPR3 doc is a lot so far, the book (which
is already 380+ pages in draft form) tells everything, including the
hidden capabilities of ZCPR3.  For instance, you may be familiar with
the shell concept and the RCP concept, but what happens if you COMBINE
them???  Wonderful, wonderful ... golly, gee whiz, Batman!  I can't
stand it ... more later.

Re:   booting in different user areas

Rick,

Hi. Thanks a lot! I made a little 3 byte patch to my BIOS and low and
behold, I boot into A15:. The shell idea sounds good too, for other
things, but this does
solve my problem at the moment. I'm looking forward to the books and the
phase 2 stuff. I'd like to know how to go about writing a shell and
using the
shell stack and the message buffer. I actually started working on one
for
ZCPR2 a while back (in C) but with the shell stack, I'll postpone that
'till I
know more about it. You I'm having fun with it! I think the aliases are
the
most usefull things of all (in conjunction with the FCP). I've got tons
of things
I'd like to do with it, but no time. It's made my work a lot easier too.
Well, 
thanks again, as usual! Take it easy....
                                               Isaac.
