The "PS/2 Mouse Port" is different from COM1 or COM2
knowledge
serial ports to which you can also connect a Mouse. This
mainboard features an extra PS/2 Mouse port, so when you
buy a mouse, be sure that it is a PS/2 Mouse before
connecting it to this port. But if you cannot find any PS/2
Mouse, you can still use COM1 or COM2 to connect a
serial mouse to your computer.
