Lines: 5 Whatever reference you are using for int 33H calls should have a function called Initialize Mouse (I think it is functio 0) that returns in one of the registers (AX, I think) -1 if not ready and 0 if it is ready. That is the easiest way I can think of, since you should have the documentatino right in front of you.
