Re: why inter-changing pci slot works?

Hello group!

Sometime it happens that two adjacent PCI cards don't work. But as you
interchange their slots. The pair starts working. Why is it so?

Is it related to the priority of the IRQs?

Thanks



It would help if you were more specific. For example, when you say
"interchange their slots" do you mean swap the two devices? Or move one
of the devices to an empty slot? What devices?

Okay, to be more specific sometimes back I had an internal modem card on
slot 1 and soundcard on slot 2. They didn't work with that arrangement.
I swapped the cards then and both of them were working. Recently, I put
the ethernet card in the second slot. It didn't work. I just changed its
position to the 3rd slot and it worked! This time it is the only card so
I think IRQ consideration is out of question. Right?
