IDE Prefetch Mode
The onboard IDE drive interface supports IDE prefetching, for faster drive access. If you install
a primary and secondary add-in IDE interface, set this field to Disabled if the interface does not
support prefetching.
IDE Primary/Secondary Master/Slave PIO
Each IDE channel supports a master device and a slave device. These four items let you as-
sign which kind of PIO (Programmed Input/Output) is used by IDE devices. Choose Auto to let
the system auto detect which PIO mode is best, or select a PIO mode from 0-4.
IDE Primary/Secondary Master/Slave UDMA
Each IDE channel supports a master device and a slave device. This mainboard supports Ul-
traDMA technology, which provides faster access to IDE devices.
If you install a device that supports UltraDMA, change the appropriate item on this list to Auto.
You may have to install the UltraDMA driver supplied with this mainboard in order to use an
UltraDMA device.
