Primary Master/Slave PIO
The IDE PIO (P rogrammed Input / Output) fields let you set a P IO mode (0-4)
for each of the IDE devices that the onboard IDE interface supports. Modes 0
to 4 will increase performance progressively. In Auto mode, the system
automatically determines the best mode for each device.
The Choices: Auto

Primary Master/Slave UDMA
Ultra DMA function can be implemented if it is supported by the IDE hard
drives in your system. As well, your operating environment requires a DMA
driver (Windows 95 or OSR2may need a third party IDE bus master driver). If
your hard drive and your system software both support Ultra DMA, select Auto
to enable BIOS support.

(default), Disabled.

you install a primary and/or secondary add-in IDE interface, set this option to
“Disabled”.
The Choices: Enabled
