Some of the newer motherboards have a combo PS/2 port for a mouse or keyboard so just plug it in a try it. Since you did not give us any info at all on the hardware I can't even guess what ports you have.
I have gigabyte GA z77mx d3h.....I have not tried to connect keyboard ps2 port on mouse's ps2 port.......
I just bought a new cpu so I don't want to screw that up, I can give it a try if it is safe to try
If you look at the port, it is colored with both the mouse and keyboard connector colors, so you can use it for either.
really, I looked the image from here and it has both purple and blue colour, but the strip which is given in the mobo(which I fitted in the cabinet to get these ports) has a icon of mouse on it, but the icon of keyboard has 2 usb ports
