The “PS/2 Mouse Port” is different from COM1 or COM2 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.
