Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO
mode (0-4) for each of the four IDE devices that the onboard IDE inter-
face supports. Modes 0 through 4 provide successively increased
performance. In Auto mode, the system automatically determines the
best mode for each device.

The choice: Auto, Mode 0, Mode 1, Mode 2, Mode 3, or Mode 4.

33, select Auto to enable BIOS support.
