Adding and Replacing Parts
One PCI card slot and two PCI Express x8 (wired as x4) card slots are not
available for use if a graphics riser card is installed for the dual-graphics
configuration. Instead, an additional PCI Express x16 slot is available for the
second card in the dual-graphics configuration. If you are upgrading from or
downgrading to a single graphics to a dual-graphics configuration, you will
need additional parts. Contact Dell to obtain optional upgrade or downgrade
parts (see "Contacting Dell" on page 287).
See "System Board Components" on page 27 to locate the PCI Express x1
card slot. To remove a PCI Express card, see "Removing an Expansion Card"
