David, 

You ask good questions.

1)
I've done an implementation of a protected mode 286 Minix system and made
substantial changes across the board.  I'm going to try to understand what
I did and see how it fits into 1.3/1.4 (it was based on 1.1).

Bruce Evans (munnari!ditsyda.oz.au!evans@uunet.UU.NET) has done work with
286 and 386 protected mode Minix.  I'm off the opinion Minix fits into a
386 machine much easier than a 286 machine (i.e if you want to do anything
more than 1 text/1 data segment).

2) The Minix system is 3 distinct programs and it isn't a monolithic kernel
like Unix is.  I guess you would need /kernel, /mm and /fs -- there is some
patching and clumsiness in coordinating the building of minix images.

The biggest problem I found was I had to do a format each time I built a
system -- that's one of the reasons I began booting from DOS and then
switch to minix after booting.

I also would like to boot in a more conventional way instead of building a
magic image.
