3-7-1 Onboard IDE Function
IDE Master/Slave PIO
The two IDE PIO (Programmed Input/Output) fields let you set a PIO mode for each of
the two 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.
IDE Master/Slave UDMA
Ultra DMA133 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). If your hard drive and your system software both support
Ultra DMA133, select Auto to enable BIOS support. The settings are: Auto,
Disabled.
