Well, IRQs are always a headache. But if humans can't do it, do you think computers can do it better? look at /proc/interrupts and /proc/ioports to see what your system is taking. (You probably know that already.) Anyways, back to the problem. My first suggestion is to change the following line in isapnp.conf L42 > (CONFIGURE ROK4120/305419896 (LD 0 to (CONFIGURE ROK4120/305419896 (LD 0 (ACT N) See if that clears things up. This resets the card. Good luck! Marshal
