IRQ stands for Interrupt Request - it's a way of telling apart hardware interrupts. Different devices can use different IRQ numbers. Original 8086 and 80286 processors have no direct means to differentiate between hardware interrupts (except NMI). The Interrupt Controller chip takes care of that with its IRQ numbering system - at least according to my knowledge. (please someone correct me if I'm wrong!) -- /\/\atjaz |<ovac FRI LJ On 7 Dec 1998, Spike wrote: > HI! > > What's the difference between INT and IRQ? > > SPIKE > > >
