EPIA V-Series Overview
The VIA EPIA V-Series Mainboard is the latest edition to the Mini-ITX family, the
world’s smallest integrated mainboard platform at the forefront of silent x86
computing. Gone is the traditional platform noise that is unacceptable for
entertainment or productivity applications key to your success in the living room,
office and classroom environments. The EPIA V provides system designers and
enthusiasts with a 17cm x 17cm, optionally fanless, computing platform for building
the attractive lifestyle and productivity devices that are pioneering the age of
ubiquitous computing. Applications for this dream catalyst platform are limited only
by the scope of your imagination.
The EPIA V is available in both fan-cooled and fanless versions due to its ultra low
power/heat characteristics. A fanless EPIA V platform is completely silent with no
moving parts. Fan-cooled versions are virtually silent with a noise rating of 25dBA @
one meter, the equivalent to a person whispering from one meter away. Compare
this to today’s average PC platform with a rating of 45dBA @ one meter or the
equivalent of two people having a normal conversation @ one meter. Running at an
average of 18 watts, the EPIA V platform consumes around 35% of the power
required to run today’s average PC thus increasing system reliability and longevity as
well as reducing total cost of ownership over the lifetime of the platform. Examples
of the lifestyle and productivity devices being built using the EPIA V platform include
home network gateways and servers, automated home security and lighting
systems, education PCs and terminals, in-car PCs, and solar powered PCs. EPIA V is
rewriting the x86 platform design rules, so let your imagination run wild and join the
revolution.
Featuring the proven VIA Apollo PLE133-T chipset with an advanced integrated AGP
2D/3D graphics engine and a choice of onboard VIA C3 or fanless VIA Eden
processors running at speeds of up to 1GHz, the VIA EPIA V-Series offers a wide
variety of highly integrated platforms for building a broad spectrum of quiet running,
affordable mini PCs and servers for the home, corporate, and educational markets.
Other features include support for up to 1GB PC133 SDRAM, dual channel audio, an
extensive set of connectivity features such as USB1.1, TV Out, and a 10/100 Mbps
Ethernet controller, one PCI slot, and an FDD connector.

Noise Level Data
VIA and the EPIA series have been at the forefront of the quiet computing initiative.
The EPIA V–Series has been designed to be totally non-obtrusive with noise levels
equivalent to a person whispering. With noise levels ranging from the totally silent
EPIA VE5000 to 25dBA for the EPIA V10000, a new wave of system design
innovation and exciting opportunities are being created in an almost limitless number
of emerging new market segments - ranging from silent running mini-PCs and living
room digital media entertainment centers to Car PCs and a host of embedded
applications such as Kiosk, POS, and Industrial Control machines.

The dBA scale is logarithmic, i.e. 10 dBA represents a doubling in volume. dBA values are measured at a
distance of one meter.
Power Consumption Data
The following graphs are a comprehensive comparison of power consumption results
for a range of typical PC applications with the VIA EPIA V-Series mainboards
compared to the typical “one size fits all” platform that is being promoted by others
in the PC industry. We have also included the EPIA M10000 mainboard as a frame of
reference.
The “one size fits all” system that we are using as a reference platform is an Intel
845-based Pentium 4 platform and we are comparing the power consumption to that
of the VIA EPIA V-Series Mini-ITX mainboards. All tests were conducted using the
Microsoft Windows® 2000 operating system and include the wattage consumed by
the total platforms.

Power consumption of EPIA V’s flagship V10000 is only half of that of the reference
platform. The fanless VIA EPIA VE5000 uses a meager 33% of the power that the
reference platform. This is significant as power sensitive systems like in-car MP3
systems are gaining in popularity.

Running Network Apps
The power consumption comparison for network applications was run while
transferring large data files over a standard 10 Base T network. Here again the
power consumption of the Intel reference platform is considerably more than that of
the VIA EPIA V-Series with the EPIA VE5000 drawing less than 40% of the power of
the reference platform.

EPIA V-Series Linux & Microsoft Driver Support
Linux Driver Support
The EPIA V-series mainboards have a very high degree of support under Linux.
Support and drivers are provided through various methods including:
•Drivers provided by VIA
•Using a driver built into a distribution package
•Installing VIA’s pre-compiled driver binary
•Compiling VIA’s driver source code
•Installing a third party driver (such as the ALSA driver from the Advanced
Linux Sound Architecture project for integrated audio)
Full instructions for the most popular distribution packages are updated monthly and
are available for free download from the Linux Arena on www.viaarena.com The
Linux Application notes on VIA Arena also contains further useful information to
optimize system performance, such as increasing IDE performance beyond the
capabilities of an in-built driver, measuring hard disk performance, enabling
hardware monitoring features and other practical guides such as installing CD re-
writers, enabling the USB 2.0 controller, and much more.
For OEM clients and system integrators developing a product for long term
production, other code and other resources may also be made available. You can
submit a request either through the Developers portal on VIA Arena, or through your
VPSD support contact. Alternatively, VIA in some circumstances will also work
towards providing a driver to suite your specific needs.
The Linux Arena is updated at least once per month. Other information, notes and
links to specific areas of interest can also be found on the EPIA Mainboards driver
page. Many OEMs and system integrators also find it valuable to discuss their

development with other Linux users in the dedicated Linux Category of the VIA Arena
Forums, which is monitored by VIA staff.
Microsoft Driver Support
EPIA V offers full support for the complete range of Microsoft operating systems.
A Windows XP Embedded support package for EPIA V mainboards is available on the
WinXP Embedded Applications Notes page, to facilitate evaluation and development.
OEMs and System Integrators should, however, customize their own binary images
according to their actual product specifications and application requirements. Sample
component implementation for the PLE133 and Northbridge as well as integrated
audio on the VT8231 Southbridge is also provided to assist in development. Updates
to this support page are made on a monthly basis and further sample components
will be released. Components of the VIA EPIA V mainboard are also supported in
Service Pack 1 (SP1).
