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 interface supports. Modes 0
through 4 provide successively increased performance. In Auto mode, the system
automatically determines the best mode for each device. The settings are: Auto,
Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.
Primary/Secondary Master/Slave UltraDMA
Ultra DMA/33 implementation is possible only if your IDE hard drive supports it and the

DMA/33, Ultra DMA/66 and Ultra DMA/100 select Auto to enable BIOS support. The
settings are: Auto, Disabled.
