1. Turn off your computer. Keep the computer plugged in so that it
remains grounded while you install the AT serial board.
2. Remove the top or side cover of the computer.
3. Remove the expansion slot cover on the back of the computer.
4. Insert the AT serial board into an unused slot with the serial
connectors sticking out of the opening on the back panel. Make sure

seem to click firmly into place, even though it is only part of the way
in. Figure 2-4 shows the installation of an AT serial board.
