The IDE connectors support the provided IDE HDD ribbon cable. After con-
necting the single end to the board, connect the two plugs at the other end to your
HDDs. If you install two IDE devices on the same cable, you must configure the
second device to slave mode by setting its jumper accordingly. (Refer to your IDE
device document for the jumper settings. Pin 20 is removed to prevent inserting in
the wrong orientation when using ribbon cables with pin 20 plugged.)
