OnChip IDE Channel0/1
The integrated peripheral controller contains an IDE interface with
support for two IDE channels. Choose Enabled to activate each
channel separately.
IDE Prefetch Mode
The onboard IDE drive interface supports prefetching, for faster drive
accesses. Set to Disabled if your primary and/or secondary add-in IDE
interface does not support prefetching.
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 auto-
matically determines the best mode for each IDE device.
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.
