Some mouse devices are designed for the round mouse connector on the back of your
computer, while others are designed for the D-shaped serial connector. Either type of
mouse will operate, provided you have the correct device driver installed.

 Monitor Port

The monitor port allows you to connect a variety of video graphics array (VGA) or super video
graphics array (SVGA) monitors to your computer. Refer to “Selecting a Monitor” on
page 14 for information on monitors, and to “SVGA Mode” on page 16 for supported video
modes.
