Don't try and use the '286 to circumvent the necessity for segmentation.
The '286 in protected mode enforces segmentation much stronger than in
real mode.  I would recommend getting a good book that discusses
protected mode, and read it.  

I just finished writing two magazine articles on how to enter and
leave protected mode, along with lots of undocumented goodies about
the '286 and '386.  At this point I don't know if they will be accepted
for publication (as each article is 8-10 pages, and includes 20 or more
pages of figures and source code).  If the articles are accepted, you
can read them in TECH SPECIALIST in a couple of months.  If they are
rejected, then I will post them to the net.
