Greetings everyone!
I'm having some trouble with IRQs and multiple video cards. For some reason Linux keeps assigning IRQ 16 to 3 of my video cards.
I've already disabled most on board options in the bios and I don't have options to specifically assign IRQs. Is there a way to manully assign IRQs? I have more then enough free.
Thanks for any help!
