IDE Prefetch
Mode The onboard IDE drive interfaces 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.
Primary Master/
Slave PIO Each channel supports a master device and a
slave device. These items let you assign which
kind of PIO (Programmed Input/Output) is used
by IDE devices. You can choose Auto, to let
the system auto detect which PIO mode is best,
or you can install a PIO mode.
Primary Master/
Slave UDMA Each channel supports a master device and a
slave device. This motherboard supports
UltraDMA and 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.
