CN23/CN23A (USB 2/3 and 4/5 Connectors):
If you want to use an USB Keyboard, you must enable the USB keyboard support
function in BIOS's Integrated Peripherals menu (See Section 3.4). This board contains an
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. Pins [ 5-6 ] and [ 9-10 ] are shorted (default) to enable the back-panel
audio function.
