editPut in some pictures of how it talks to the processor to bring it into attention.
This is very specific to the IBM-PC derivatives. A lead-in of a more general nature would be nice. Wiml 05:00, 16 Feb 2005 (UTC)
Are IRQs specific to the IBM PC architecture? I think the article should mention something about this.
- No! But you might get that impression after reading this (bad) article. Mirror Vax 16:51, 24 Jun 2005 (UTC)
IRQ's are interrupt requests. There is at best a distinction between the act of interrupting, and the physical interrupt line. Lines should be postfixed as IRQ line in either case.
They are also the terminology of the 8259 Programmable Interrupt Controller (PIC) interrupt output lines.
Maybe this page should be a disambiguating page instead?
Only 16 IRQs?
editAre there only 16 IRQs? I have this on my machine:
