Matrox Helios Series Installation And Hardware Reference page 25

Important Some computers have a large, black-ridged heat sink that prevents long boards
from using some of the PCI board slots. Matrox Helios must not touch the heat
sink. Therefore, choose a slot where the board completely avoids it. If you cannot
find a suitable slot, contact your computer dealer.
If you also need to install the adapter board(s) of Matrox Helios, you need an
additional slot. This slot need not be adjacent to the Matrox Helios board. Note
that the adapter boards do not plug into a slot's PCIe/PCI/PCI-X connector; they
attach only to the back of the computer's chassis. Since the Matrox Helios eA/XA's
adapter board is longer, it has a support tab that can be removed; if a
PCIe/PCI/PCI-X slot is selected, the tab will fit into the slot's connector, ensuring
that the board does not move.

If necessary, remove boards from your computer to make room for your Matrox
Helios board and if required, its adapter board.
3. If there is a metal plate at the back of the selected slots, remove it. Keep the screw
from the top of the plates to anchor your boards once they are installed.
