       IDE Primary/Secondary/Master/Slave PIO 

The IDE PIO (Programmed Input / Output) fields let you set a PIO 
mode (0-4) for each of the IDE devices that the onboard IDE interface 
supports. Modes 0 to 4 will increase performance progressively. In 

Auto mode, the system automatically determines the best mode for 
each device. 

The Choices: Auto
