The PCI Express x1 card slot is not available for use if a graphics card is installed in each of the PCI
Express x16 card slots in a dual graphics card configuration. If you are upgrading from a single graphics
card to a dual-graphics card configuration, you will need to remove any card installed in the PCI Express
x1 card slot (see "System Board Components" on page 79 to locate the PCI Express x1 card slot). To
remove a PCI Express card, see "Removing PCI and PCI Express Cards" on page 85.
