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
through 4 provides successively increased performance. In Auto mode, the
system automatically determines the best mode for each device.
The Choices: Auto (default), Mode0, Mode1, Mode2, Mode3, Mode4.
IDE Primary / Secondary Master / Slave UDMA
Ultra DMA/100 functionality can be implemented if it is supported by the IDE
hard drives in your system. As well, your operating environment requires a DMA

drive and your system software both support Ultra DMA/100, select Auto to
enable BIOS support.
The Choices: Auto (default), Disabled.
