If these ide controllers are add-on boards, then you could try moving them between PCI slots -- as the slots generally have different primary interrupt lines. When the board runs out of unique lines, they are generally wired to re-use lines on different slots. The manual for the board will generally tell you how the lines are routed. If the devices are using the same physical interrupt line, then it is not possible for software or BIOS to move them to different lines. If these devices are functions in the same device, it is possible that there is some internal (BIOS or firmware) setting to tell it to use two interrupt wires instead of one. Once the wire for the device is determined, it is up to the BIOS and the OS to program (or not) an interrupt router to assign the wire to an interrupt input pin. Your dmesg will tell us if this is happening on this board. -Len - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
