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.

/ Mode 0 ~ Mode 4
Primary / Secondary Master / Slave UDMA
This option allows you to select the mode of operation for the Ultra DMA/33
implementation. This is possible only if your IDE hard drive supports UDMA
and the operating environment includes a DMA driver (Windows 95 OSR2
or a third party IDE bus master driver).
