FNENI      Enable Interrupts (8087, No-wait)        Exception Flags: None

FNENI

       Logic:      Interrupt Enable Mask . 0

     FNENI is the no-wait form of FENI. It allows the 8087 only to generate
     interrupt requests by clearing the Interrupt Enable Mask in the control
     word.

     This instruction enables interrupts in the 8087 only. It is recognized
     but ignored in later coprocessors.

        Note:          You should use this no-wait form of the instrcution
                       only when there is a danger of generating an infinite
                       wait condition.
