This feature enhances disk performance by allowing
multisector data transfers and eliminates the interrupt
handling time for each sector. Most IDE drives,
except with old designs, can support this feature.

Setting this item to Auto activates the HDD speed
auto-detect function. The PIO mode specifies the
data transfer rate of HDD. For example: mode 0
data transfer rate is 3.3MB/s, mode 1 is 5.2MB/s,
mode 2 is 8.3MB/s, mode 3 is 11.1MB/s and mode 4
is 16.6MB/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.
Refer to section 2.3 "Connectors" for details
on how to connect IDE device(s).
