Follow these steps to remove the video daughterboard in your
computer and install the enhanced one:
1. Remove the two hex screws securing the video port to the
back of the computer. (If you do not have an appropriate
hex driver to remove the screws, you can try using a small
pair of needle-nosed pliers; but be careful not to damage
the screws or the interface port.) Set the screws aside in a
safe place.
