Check the motherboard manual. Sometimes they explictly list which slots share IRQs (And by share I mean are physically tied to the same wire). I know many Asus boards have that information in the manual. So in many cases other than changing slots, there is nothing you can do to change the IRQ sharing, since the slots are physically sharing the interrupt. -- Len Sorensen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
