I can think of a few possibilities.

1)	Have the FIRST thing your 80286-compiled program does call a
	routine in a separate module, which is compiled for 8086/88.  That
	routine does all the checking for 8086/88, and returns false if
	an 8086/88 is present.  The main routine exits in that case.  You
	are probably ok doing this, as long as you don't pass any parameters
	to that routine.  (since those would be pushed onto the stack)

2)	Compile your main routine for 8086/88.  But strip out all the
	code but the check for 8086, and put this code in functions
	that are in a module compiled for 80286.

Admittedly, these are pretty kludgy.  I'm not sure if there's a way to
compile for two different chips in one module.
