   A friend of mine wants to write some software using the undocumented
LOADALL (or whatever) instruction on the 80286.  This instruction
apparently offers a special escape to real mode on the 286 without
having to go through the reset register and BIOS on the PC/AT.  There
was also a recent rumour that IBM had requested that this instruction
be put back into the 386, from which it had been removed.

   Can someone please supply me with details on this instruction's
format and function?  It would be very greatly appreciated.  I know
that Microsoft and IBM are already using it, so it wouldn't be the
first time someone got it.
