I am probably wrong, but my understanding is that this cannot be done with a
286 chip as it is because it lack Memory Management such as is built into the
386 chip.  I have come across a product, which I have not tried, that claims
to allow this.  Called the "All ChargeCard", from ALL Computers Inc., of
Toronto, Canada (phone 416-960-0111).  You remove your 286 processor and plug 
it into their Card, which in turn in then plugged into the 286 socket on the 
motherboard.  It now provides memory management, and will allow (they claim) 
extending DOS to 960K, and use Extended Memory as Expanded Memory (just like 
is done with a 386 system).  (They even claim that the multi-tasking/multi-user
operating system PC-MOS/386 will then run on your 286 system.)  I have not 
tried it yet because of the ~$500-$600 price, though others may consider this 
an inexpensive way to extend and fully utilized the capabilities of their
system with its "brain-dead" 286 chip.
