Suggest a reason for the following. the statements are alltrue.
a) we should disable interrupts while hooking interrupt 8h. i.e. while placing its segment and offset in the interrupt vectortable.
b) we need not do this for interrupt 80h.
c) we need not do this when hooking interrupt 8h from insidethe interrupt handler of interrupt 80h.
d) if no eoi is sent from interrupt 9h and no chaining isdone, interrupt 8h still comes if the interrupt flag is on.
