1. Product Overview
The VIA EPIA-P900 Pico-ITX mainboard is a com act native x86 mainboard
o timized for systems in embedded and multimedia a lications. It can also
be used for various domain a lications such as medical PC, industrial PC, and
etc. The mainboard is based on the VIA VX900H Unified Digital Media IGP
chi set that features the VIA Chrome9™ HD with 2D/3D gra hics and video
accelerators for rich digital media erformance.
The VIA EPIA-P900 mainboard has integrated HDMI ort and comes with re-
installed I/O com anion card called P830-A, and an o tional P830-B
ex ansion card. The P830-A I/O com anion card is connected through
onboard in headers carrying the back anel I/O such as VGA ort, RJ45 LAN
ort and USB 2.0 orts. The P830-B ex ansion card rovides two Mini PCIe x1
slots.
The VIA EPIA-P900 has a owerful, secure, and efficient VIA Eden
™
X2 dual
core rocessor. The VIA Eden
™
X2 rocessor includes the VIA AES Security
Engine, VIA CoolStream
™
Architecture and VIA PowerSaver
™
Technology.
The VIA EPIA-P900 includes one 1066 MHz DDR3 SODIMM slot that su ort
u to 4 GB memory size. The VIA EPIA-P900 rovides su ort for high fidelity
audio with its included VIA VT2021 High Definition Audio codec. In addition it
su orts two SATA 3Gb/s storage devices and fully com atible with
Microsoft
®
and Linux o erating systems.

1.1. Key Features and Benefits
1.1.1. VIA Eden
™
X2 Processor
The VIA Eden X2 is a 64-bit su erscalar x86 dual core rocessor based on a
40 nanometer rocess technology. Packed into an ultra com act NanoBGA2
ackage (measuring 21mm x 21mm), it delivers an energy-efficient yet
owerful erformance, with cool and quiet o eration. The VIA Eden X2 is
ideal for embedded system a lications such as industrial PCs, test machines,
measuring equi ment, digital signage, medical PCs, monitoring systems,
gaming machines, in-vehicle entertainment, etc.
Note:
For Windows 7 and Windows Server 2008 R2 users only:
I encounter the issue such as the operating system does recognize the VIA Dual-Core CPU as two
processors instead o one processor with two cores. Download and install the hot ix released by
Microso t to address this issue. The downloadable hot ix is available at
http://support.microsoft.com/ b/2502664
1.1.2. VIA VX900H Chipset
The VIA VX900H Unified Digital Media Chi set is designed to enable high
quality digital video streaming and DVD layback in a new generation of
fanless, small form factor PCs and IA devices. The VIA VX900H features VIA
Chrome9
™
HD with 2D/3D gra hics and video acceleration, DDR3 1066/800
su ort, motion com ensation and dual dis lay su ort to ensure a rich
overall entertainment ex erience.
1.1. . Expansion Option
The EPIA-P900 further roves its versatility by roviding an ex ansion o tion
connector that uses a “PCIe and USB 2.0 combinations board-to-board
connector” for P830-B ex ansion card. The P830-B ex ansion card rovides
two Mini-PCIe x1 slots.
The com anies using the EPIA-P900 with P830-B ex ansion card obtain the
maximum benefits and enable to slowly roll out u grades as necessary
instead of having to re lace everything all at once.
