set the way you want them. (Pressing the reset button on the logic board
changed these settings.) For more information about working with control
panels, see the information about customizing your computer in Macintosh

Mac OS environment, or you can simultaneously display both environments

connect it to the computer’s built-in monitor port.
Attach the monitor cable to the
built-in monitor port on the back
of your computer.
