      note:
    Some cards require two slots.
  2. Align the connectors on the card with the slot on the system board.
  3. If the card has a support bracket, align it with slot in the PCI card guide.
  4. Lower the card down over the slot on the system board.
  5. Press down on the card until it is fully seated.
