1.1.2. VIA VX900 Chipset
The VIA VX900 Unified Digital Media Chipset is designed to enable high
quality digital video streaming and DVD playback in a new generation of
fanless, small form factor PCs and IA devices. The VIA VX900 features VIA
Chrome™ 9 HC3 with 2D/3D graphics and video acceleration, DDR3 1066/800
MHz support, motion compensation and dual display support to ensure a rich
overall entertainment experience.
1.1.3. Flexible Power Options
The VIA EPIA-M860 comes with two power input options: ATX and DC-in. The
ATX version supports standard 20-pin ATX power supply connectors. The DC-
in version requires a 12V/5A max input. The AC/DC adapter can be purchased
as an option with the DC-in version. The DC-in version also has an onboard 4-
pin power supply connector.
1.1.4. Modular Expansion Options
The VIA EPIA-M860 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-M860 enables companies to slowly roll out
upgrades as necessary instead of having to replace everything all at once. This
ensures that companies using the EPIA-M860 obtain the maximum benefits
from its past investments in PCI expansion cards.
The VIA EPIA-M860 also includes a 1-Lane PCI Express 2.0 expansion slot that
provides protection against obsolescence.
The VIA EPIA-M860 further proves its versatility with its included Mini PCI
Express slot. Companies can feel free to design low-profile systems based on
the versatile EPIA-M860.

2.2.4. CMOS Battery Slot
Depending on the manufacturing option, the mainboard will either be
equipped with a CMOS battery slot or a 2-prong cable CMOS battery
connector. The default option is the CMOS battery slot, which is compatible
with CR2032 coin batteries. The CMOS battery slot is labeled as “BAT2”. If
equipped, the 2-prong cable CMOS battery connector will be labeled “BAT1”.
