Disable Interrupts
8087 Only
 
Syntax:  FDISI
         FNDISI
 
Disables interrupts by setting the interrupt enable mask in the control
word. This instruction has wait and no-wait versions. Since the 80287
and 80387 do not have an interrupt enable mask, the instruction is
recognized but ignored on these coprocessors.
