When you boot and get "found new hardware" messages, DON'T cancel them. Go through the procedure as you would normally.....but when you are presented with the list of driver catagories, pick "UNSUPPORTED DEVICE".
Unfortunately, you will have to do this 7 or 8 times, but it's worth it, because if you just cancel the "found new hardware" messages, EVERY time you boot it will find the ESI again and start throwing up messages.
