-CPU-generated (80186+) - BOUND RANGE EXCEEDED
-generated by BOUND instruction when the value to be tested is less than the indicated lower bound or greater than the indicated upper bound.
-returning from this interrupt re-executes the failing BOUND instruction
-Generated if the divisor of a DIV or IDIV instruction is zero or the quotient overflows the result register; DX and AX will be unchanged.
