I want a certain program to be able to distinguish between an 80386
and an 80286.  I could try using self-modifying code (to test the size
of the prefetch queue, but I was wondering if there might be simpler
methods.  This test will be done on a system running MS-DOS, so I
guess that means the '386 will be in real mode.  Any help would be
appreciated.
