The system board is equipped with onboard serial ports (COM 1: J5 and COM 2: J7) - both in Teal/Turquoise color located at the ATX double deck ports of the board.

These ports are RS-232C asynchronous communication ports with 16C550A- compatible UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices. You can set the serial ports’ I/O address in the Integrated Peripherals submenu of the BIOS.

The system board is equipped with an onboard PS/2 mouse (Green) and PS/2 keyboard (Purple) ports - both at location J2 of the ATX double deck ports.The PS/2 mouse port uses IRQ12. If a mouse is not connected to this port, the system will reserve IRQ12 for other expansion cards.

Warning:

Make sure to turn off your computer prior to connecting or disconnecting a mouse or keyboard. Failure to do so may damage the system board.
