FNDISI Disable Interrupts (8087, No-wait) Exception Flags: None
FNDISI
Logic: Interrupt Enable Mask . 1
FNDISI is the no-wait form of FDISI. It sets the Interrupt Enable
Mask in the control word, which prevents the 8087 from issuing
interrupt requests.
This instruction disables 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.
