What determines the number of IRQs is IBM, 16 years ago. http://www.PCGuide.com/ubb/smile.gif When the original PC/AT was produced it had two interrupt controllers, cascaded, for a total of 15 IRQs. Clones were produced with the same design for compatibility, and we've been stuck with it ever since. http://www.PCGuide.com/ubb/smile.gif All PCs have the same number, and most use about 75% of them for the same hardware items.
