an available slot at the rear of the system chassis then insert the serial port cable to the COM
connector. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of the COM
connector.
BIOS Setting
Configure the serial COM ports in the Advanced menu ("SIO NUVOTON6116D" submenu) of
the BIOS. Refer to the chapter 3 for more information.
