Six options are available: Auto Mode 0 Mode 1 Mode 2 Mode 3 Mode 4. The five IDE
PIO (Programmed Input/Output) items let you set a PIO mode (0-4) for each of the four IDE devices that
the onboard IDE interface supports. Modes 0 through 4 provide successively increased performance. In
Auto mode (default setting), the system automatically determines the best mode for each device.
