I have looked everywhere in the forums to find the answer to my question and I could not find it anywhere. So I ask of your help. I have a Sony DRU-510A DVD +- RW and in Device Manager Under Primary IDE Devices/Advanced Settings/Device 1 it says for "Current Transfer Mode" PIO Only. But in the drop down box it says DMA if available. How do I get DMA in Current Transfer Mode? I am running Windows XP Pro SP2. Please help!!!!
