Now that's all nice and jolly and 3.0 release works fine as much as i can see so far but here is the question: All the PCI devices seem to be mapped to the same IRQ 14. The bios setup of Dell's is limited to say the least so there are no options to control PCI mapping in there. How can i map those devices to different IRQ's and should i bother at all? I heard there are perfomance implications when sharing same IRQ and this machine's perfomance is critical.
