1. Open the Device Manager. One way to do that is to right click on "My Computer", select the Hardware tab, and Select Device Manager.
2. Expand "IDE ATA/ATAPI Controllers" and double-click on "Primary IDE Channel" or "Secondary IDE Channel" depending on which the burner is on (normally the Second).
3. Under the "Advanced Settings" tab, check the "Device 1" setting (again if this is the burner). Set to PIO.
