Integrated Peripherals

On-Chip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with support for
two IDE channels. Choose Enabled to activate each channel separately.
IDE Primary/Secondary Master/Slave PIO
The four items allow you to set a PIO (Programmed Input/Output) mode for
each of the four IDE devices that the onboard IDE interface supports. Modes
0~4 provide increased performance. In Auto mode, BIOS automatically deter-
mines the best mode for each IDE device.
IDE Primary/Secondary Master/Slave UDMA
Ultra DMA implementation is possible only if your IDE device supports it and
your operating environment contains a DMA driver. If both your hard drive
and software support Ultra DMA 33/66/100, select Auto to enable BIOS support.
