Your best solution, unfortunately, is to buy a IDE controller and connect your stuff to that and disable the onboard. If you do that, stay miles away from the Promise stuff and you should be OK. > Does anyone have any information on what hacking is required to get the > CMD 640 to work? Normally, it's transparent and included in the wdc controller. Unless someone wanted to hack up a specific driver for it I doubt we'll see anything come of it. Just a hunch, but check the IRQs and make sure the Ethernet card isn't using IRQ 15 or 14.
