If you want to use a USB Keyboard, you must enable the USB keyboard support function
in BIOS's Integrated Peripherals menu (See Section 3.4). This board contains a USB Host
controller and a root hub with two connectors is included for an optional USB Adaptor
(USB 2/3 and 4/5).
CN24 (Front Audio Connector)
This connector gives you the option of a front-panel audio-jack cable ext. to be plugged
into a special custom-designed system case.
Simply remove the two jumper caps at pin [5-6] and [9-10] then plug it into the (optional)
cable ext. connector. Pin [5-6] and [9-10] are shorted (default) to enable the back-panel
audio function.
