It is higher performance than older controllers and offers additional features, such as hot-plugging, but compatibility mode degrades the performance and removes the extra features. http://en.wikipedia.org/wiki/Advanced_Host_Controller_Interface I paid for it, and I want to use it! 8^) > > I will have a new BIOS soon and wonder if I will need to do the same > thing?
