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.
