Connecting the Mouse
Your computer has an auxiliary port for an IBM PS/2 compatible
mouse that uses a miniature DIN (6-pin) connector. If you have
purchased a mouse with this type of connector (or adapter), you
can connect it to the built-in port on your computer.
If you purchased a mouse with a serial connector, you can
connect it to the built-in serial port on your computer.
If you have another kind of mouse that requires a different
interface port, you need to install an option card to provide the
interface.
To connect a mouse to the built-in mouse port, hold the mouse
plug so it is oriented properly with the computer socket. Insert
the plug into the appropriate socket, marked with a mouse icon,
as shown in the following illustration.
