USB Ports and CPU/System FAN.

Floppy Disk Drive Connector: FDD1

The mainboard provides a standard floppy disk drive connector that supports
360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.

Fan Power Connectors: C_FAN1/S_FAN1/S_FAN2/NB_FAN1

The C_FAN1 (processor fan), S_FAN1 (system fan 1), S_FAN2 (system fan 2)
and NB_FAN1 (NorthBridge Chipset fan) support system cooling fan with +12V. It
supports three-pin head connector. When connecting the wire to the connectors,
always take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If the mainboard
has a System Hardware Monitor chipset on-board, you must use a specially de-
signed fan with speed sensor to take advantage of the CPU fan control.
