Note:The main board will automatically adjust the COM ports of the onboard serial ports when an external serial port is installed, but you must manually change the interrupts. (e.g. With oneexternal serial port installed, Port 1 (J3) is now COM2 and Port 2 (J2) is COM3. In this case Port 1 should be set to IRQ3 and Port 2 should be set to IRQ4.) lease refer to the following table for a further explanation.
