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 inter-
face supports. Modes 0 through 4 provide successively increased
performance. In Auto mode, the system automatically determines the
best mode for each device.
The choice: Auto, Mode 0, Mode 1, Mode 2, Mode 3, or Mode 4.
Primary/ Secondary / Master/ Slave UDMA
Ultra DMA100 implementation is possible 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 both of
your hard drive and your system software support Ultra DMA100,
select Auto to enable BIOS support.
The choice: Auto or Disabled.
