MSI Reminds You...
If you don't want to connect to the front audio header, pins
5 & 6, 9 & 10 have to be jumpered in order to have signal
output directed to the rear audio ports. Otherwise, the
Line-Out connector on the back panel will not function.

IrDA Infrared Module Header: JIR1 (Optional)

The connector allows you to connect to IrDA Infrared module. You must configure the
setting through the BIOS setup to use the IR function. JIR1 is compliant with Intel
Front Panel I/O Connectivity Design Guide.
