settings are: Disabled, Enabled (default).
OnChip IDE Primary/Secondary

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 (default), Mode 0, Mode 1, Mode 2,
Mode 3 and Mode 4.
Primary/Secondary Master/Slave UDMA
Ultra DMA/33 implementation is possible only if your IDE hard drive supports it and the
operating environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE bus
master driver)You’re your hard drive and your system software both support Ultra DMA/33
and Ultra DMA/66, select Auto to enable BIOS support.
Settings are: Auto (default) , Disabled.
