10. Primary / Secondary IDE Connectors (Two 40-1pin IDE)
These connectors support the provided IDE hard disk ribbon cable.
After connecting the single end to the board, connect the two plugs at the other
end to your hard disk(s). If you install two hard disks, you must configure the
second drive to Slave mode by setting its jumper accordingly. Please refer to the
documentation of your hard disk for the jumper settings. (Pin 20 is removed to
prevent inserting in the wrong orientation when using ribbon cables with
pin 20 plugged).

This connector connects to a ATX power supply. The plug from the power supply
will only insert in one orientation because of the different hole sizes. Find the
proper orientation and push down firmly making sure that the pins are aligned.
