DVD playback. The VIA VX900 features VIA C-9 HD DX9 with 3D/2D graphics and video accelerators,
DDR3 1066MHz support, motion compensation and dual display support to ensure a rich overall
entertainment experience.
Note:
For Windows 7 users only:
If encounter the issue such as the operating system recognizing the VIA Dual-Core CPU as two processors
instead of one processor with two cores. Download and install the hotfix released by Microsoft to address this
issue. The downloadable hotfix is available at http://support.microsoft.com/kb/2502664.

1.1.3. Modular Expansion Options
The VIA EPIA-M910 ensures long-term usability with its support for industry standard expansion options.
Its support for legacy PCI expansion cards helps to smooth and reduce the costs of transitioning to newer
expansion technologies. The VIA EPIA-M910 enable companies to slowly roll out upgrades as necessary
instead of having to replace everything all at once. This ensures that companies using the VIA EPIA-M910
obtain the maximum benefits from its past investments in PCI expansion cards.
The VIA EPIA-M910 also includes a 1-Lane PCI Express 2.0 expansion slot that provides protection against
obsolescence. Companies can feel free to design low-profile systems based on the versatile VIA EPIA-
M910.
