This 34-pin block connector supports the provided floppy drive ribbon cable.
After connecting the single end to the board, connect the two plugs on the other
end to the floppy drives. (Pin 5 is removed to prevent inserting in the wrong
orientation when using ribbon cables with pin 5 plugged).

4. Power Supply, CPU Fan Connectors (FAN)
These connectors support cooling fans of 500mAmp (6watts) or less. Orientate
the fans so that the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots. Depending on the fan manufacturer, the
wiring and plug may be different. The red wire should be positive, while the
black should be ground. Connect the fan's plug to the board taking into consid-
eration the polarity of the this connector. NOTE: The "Rotation" signal is to
be used only by a specially designed fan with rotation signal.
WARNING! The CPU and/or motherboard will overheat if there is no airflow
across the CPU and heatsinks. Damage may occur to the motherboard and/or the
CPU fan if these pins are incorrectly used. These are not jumpers, do not
place jumper caps over these pins.
