Installing an Add-on Card

The main unit of your computer has two open expansion slots: one PCI compliant slot (PCI slot 1) and one PCI Express x4
compliant slot (PCI slot 2). To PCI slot 2, you can install a PCI Express x1 or x2 compliant card as well as a PCI Express x4
compliant card. An expansion slot enables you to install a PCI standard based expansion card to expand the functionality of
your computer. Before you purchase an expansion card, make sure the card supports Windows Vista and the PCI standard.
The length of the add-on card (1) should not exceed 12.3 inches (31 cm) for PCI slot 1 and 6.7 inches (17 cm) for PCI slot 2
(the one close to the power unit).
