INT 09 - CPU-generated (80286,80386) - PROCESSOR EXTENSION PROTECTION ERROR

Desc:	called if the coprocessor attempts to access memory outside a segment
	  boundary; it may occur at an arbitrary time after the coprocessor
	  instruction was issued
Notes:	until the condition is cleared or the coprocessor is reset, the only
	  coprocessor instruction which may be used is FNINIT; WAIT or other
	  coprocessor instructions will cause a deadlock because the
	  coprocessor is still busy waiting for data
	for the 486+, a coprocessor protection error generates an INT 0D
