FDISI Disable Interrupts Exception Flags: None
FDISI
Logic: Interrupt Enable Mask . 1
FDISI disables interrupts in the 8087 only. It sets the Interrupt Enable
Mask (IEM) in the control word, which prevents the 8087 from issuing
interrupt requests. If WAIT is decoded with pending exceptions, the 8087
produces an input (whether masked or not).

Note: The opposite instruction is FENI. The no-wait
version of FDISI is FNDISI.
