OS/2 just uses protect mode of the 286;  it will (i believe) recognize
if it is running on a 386 box and use the 386's ability to switch
between protect and real mode. this increases speed of high memory
(>1meg) memory access when in the real mode box over the 8042/8047
reset and loadall instruction.  i don't see any other 386 capabilities
being used.
