USB Port 2/3 CN23, USB Port 4/5 CN23A

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 also included for an optional USB Adaptor (USB 2/3 and 4/5).

CN24 (CBOX™ 2 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.

It is recommended that you leave the default setting to prevent any burn out on your CPU.
