Setting these items to Auto activates the HDD
speed auto-detect function. The PIO mode
specifies the data transfer rate of the HDD. For
example, mode 0 data transfer rate is 3.3 MB/s,
mode 1 is 5.2 MB/s, mode 2 is 8.3 MB/s, mode 3
is 11.1 MB/s and mode 4 is 16.6 MB/s. If your
hard disk performance becomes unstable, you
may manually try the slower mode.
Caution: It is recommended that you connect the
first IDE device of each channel to the
endmost connector of the IDE cable.

Each IDE channel supports a master device and
a slave device. This mainboard supports
UltraDMA technology, which provides faster
access to IDE devices.
If you install a device that supports Ultra DMA,
change the appropriate item on this list to Auto.
You may have to install the Ultra DMA driver
supplied with this mainboard in order to use an
UltraDMA device.
