Installing a PCI card
This section contains instructions for installing a PCI card. PCI cards for your
computer must be no longer than 6.88 inches long.
Use these instructions in conjunction with the instructions that come with
your PCI card:
1 If you have a video input card already installed in your computer and you’re going to
install a PCI card in the lower PCI slot, remove the video input card temporarily to give
yourself more room while you install the PCI card. Unscrew the screw on the front of the
vertical plate that holds the video input card in place and remove the card as shown.
(You’ll reinstall the card later.)
Skip this step if there is not a video input card installed on your logic board or
if you’re installing the PCI card in the uppermost PCI slot.
Video input card If you have a video input card
installed, you may need to remove
