and power supplies. The VIA EPIA-M860 is fully compatible with Microsoft® and Linux operating systems.
1.1. Key Features and Benefits
1.1.1. VIA Nano™ 1.2GHz Processor
The VIA Nano is a 64-bit superscalar x86 processor based on a 65 nanometer process technology. Packed into an ultra
compact NanoBGA2 package (measuring 21mm x 21mm), it delivers an energy-efficient yet powerful performance, with
cool and quiet operation. The VIA Nano is ideal for embedded system applications such as industrial PCs, test machines,
measuring equipment, digital signage, medical PCs, monitoring systems, gaming machines, in-vehicle entertainment, etc.
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 C-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.

The onboard PCI slot supports 5V 32-bit PCI cards. It is not compatible with PCI cards requiring 3.3V signaling. The PCI
slot is located adjacent to the PCI Express slot. Using the PCI slot will negate the use of the PCI Express slot unless the
optional PCIE-03 riser card module is used. The location of the PCI slot is shown below.
The orientation of PCI cards can be changed from vertical to horizontal using a riser card module. Compatible optional
riser card modules include the following models: EXT-PCI-01 and PCIE-03.
The EXT-PCI-01 module enables the PCI slot to support two PCI expansion cards horizontally. The PCIE-03 module
enables the PCI slot to support one PCI card and one PCIe card horizontally. See page 71 for details on how to install
the riser card module.

5. Hardware Installation
5.1. Installing into a Chassis
The EPIA-M860 can be fitted into any chassis that has the mounting holes compatible with the standard Mini-ITX
mounting hole locations. Additionally, the chassis must meet the minimum height requirements for specified areas of
the mainboard.
If a riser card module is being used, the chassis will need to accommodate the additional space requirements.
5.1.1. Suggested minimum chassis dimensions
The figure below shows the suggested minimum space requirements that a chassis should have in order to work well
with the EPIA-M860.
Figure 40: Suggested minimum chassis dimensions
Each side of the mainboard should have a buffer zone from the internal wall of the chassis. The side of the mainboard
that accommodates the I/O coastline should have a buffer of 1.00 mm. The side on the opposite end of the I/O
coastline should have a buffer of at least 5.00 mm. The two sides adjacent to the I/O coastline should have at least a
10.00 mm buffer.
For the side that is close to the PCI slot, the buffer should be at least 100.00 mm if a riser card module will be used.

5.1.2. Suggested minimum chassis height
The figure below shows the suggested minimum height requirements for the internal space of the chassis. It is not
necessary for the internal ceiling to be evenly flat. What is required is that the internal ceiling height must be strictly
observed for each section that is highlighted. The highest part of the ceiling will be above the PCI and PCIe slots.

Appendix B. Riser Card Modules
There are two riser card modules that are compatible with the EPIA-M860: the PCIE-03 and the EXT-PCI-01.
B.1. PCIE-03
The PCIE-03 riser card has both a PCI slot and a PCIe x1 slot. This card can only be used if the mainboard has a PCI slot
properly aligned with a PCIe x1 slot. Additionally, the orientation of the PCIe x1 slot must be reversed so that the key
notch is furthest away from the key notch on the PCI slot.
Figure 66: Installing the PCIE-03 riser card

EPIA-M860 User Manual
72
B.2. EXT-PCI-01
The EXT-PCI-01 card is compatible with both 5V and 3.3V PCI slots. However, the PCI slots on the riser card are only
compatible with 5V PCI cards. The EXT-PCI-01 riser card must be correctly inserted into the mainboard’s PCI slot,
otherwise it may be damaged when the system powers on. Confirm the proper orientation of the key notch before
powering the system.
