22 Chapter 2: Hardware installation
9. Turn on your computer.
❖ When you boot your computer, Windows’ Plug-and-Play system will detect a
new graphics adapter and you will be asked to assign it a driver. At this point,
you should click on Cancel. The driver will be installed during the installation
of Matrox Orion HD software.
10. Install your Matrox Orion HD software to install the board’s driver. Follow on
screen instructions.
11. When instructed to reboot your computer, attach any other required display device
to your Matrox Orion HD board before rebooting; do not disconnect the
temporary DVI-D display device yet, even if you plan on removing it. All the
attached display devices must be used to display all or part of your Windows
desktop. For more information on connecting devices, see the Connecting SDI
digital display devices and Connecting DVI-D and RGB display devices subsections
of the Connecting external devices section, later in this chapter.
12. Once you reboot, run Matrox PowerDesk to configure your display settings.
13. Once you exit Matrox PowerDesk, you can remove the temporary DVI-D digital
display device if it is not required. Windows will automatically detect that it is no
longer present. Note that at least one display device must be attached to your
Matrox Orion HD board.
14. Disable active state power management (ASPM) for PCIe devices to maximize the
performance of Matrox Orion HD. In the BIOS, disable all ASPM (or equivalent)
settings (typically accessible from the Power management submenu of the
Advanced Configurations menu). In addition, in the operating system, disable
this option as well. For example, in Microsoft Windows 7, open the Power
Options dialog box from the Windows Control Panel. For the currently selected
power plan, click on Change Plan Settings and then click on Change Advanced
Power Settings. In the presented dialog, expand PCI Express, and then expand
Link State Power Management and set it to Off.
