Hi Harry, > Does it matter if I have several devices using the same interrupt number if > all those devices are on the pci bus ? In theory it should work fine. But if youīre facing problems with a particular card, itīs worth a try to give it an irq of its own. > I've just build a new machine, and in > the boot messages see the USB system and network card both reported with irq > 11. If it does, how do I get them on different irq's ? The assignment of irqs to pci-slots is motherboard dependant. The BIOS options are more or less cryptic. So look in your documentation of it. Nothing found? On the website of the manufacturer. Nothing found? Mail them. Iīm sorry, I dont have a URL handy, which would allow to dig in this deeper. The only source I have is a very good article of the German computer mazine cīt about this topic. But itīs longish (and German ;-) ). If you need more help, I will reread this article and post the essentials. If there are no problems, donīt care about your pci irqs. > Does FreeBSD permit irq sharing ? Yes.
