3.5 Integrated Peripherals

This option displays a list of items which defines the operation of some
peripheral items on the system's input/output ports.
OnChip IDE Channel0
OnChip IDE Channel1
You can use this item to enable or disable the primary and secondary IDE
channels that are built into this motherboard. When one or both channels are
enabled (the default value is Both) items appear which allow you to set the PIO
(programmable input/output) mode and the UltraDMA mode for master and
slave devices on the channels. We recommend that you leave these items at the
default value Auto. The system will then automatically use the best
performance PIO mode and UltraDMA mode for each device.
IDE Prefetch Mode
The built-in IDE drive interfaces support IDE presetting for faster drive
accesses. If you use an alternative IDE interface (e.g. an expansion card),
disable this field if the alternate IDE interface does not support presetting.
