I have a a Dell GX260 that seem to keep putting the hard drive to Ultra dma mode 2. The bio has a setting for hard drive to make it Quit, suggested or performance i think there's other ones but cant remember. when i put it to performance it does ultra dma 5 when you restart computer its still on dma 5 but at random times it goes back to dma mode 2 and i have to go into bio and just save and exit and it goes back to dma mode 5. So why does this seem to happen?
