To install a port expansion card, grab your Phillips head screwdriver and follow these steps:
Close Windows and power off your PC.
Disconnect your PC from its power source.
Open the system unit case.
Locate an unused PCI card slot (see Figure 3.2).
Remove the cover to the selected slot (on the back of the system unit).
Insert the card into the open slot (see Figure 3.3).
Screw the card bracket into place, using the screw from the slot cover (see Figure 3.4).
Reinstall the system unit cover and reconnect the PC to its power source.
Restart your computer.
When prompted, install the drivers for your new card.
That's it. As soon as your computer is configured for the new ports, they're ready to use!
