VIA EPIA PD-Series Overview
The VIA EPIA PD-Series Mini-ITX Mainboard is an ultra compact x86 digital I/O, 4 COM ports and dual
LAN platform with unprecedented expandability and versatility for today’s ever-growing need of
networking applications. The VIA EPIA PD features more connectivity options than any other EPIA
mainboard opening up a vast range of applications in the POS, office, public places, and commercial
LANs. Measuring a mere 17 x 17 cm, the VIA EPIA PD-series enables space and power saving systems
with minimal moving parts making it ultra reliable for 24/7 operation in a once-on-always-on network
environment.
The VIA EPIA PD-series is fully compatible with Microsoft® and Linux operating systems and is available
in a variety of configurations, including the fanless VIA Eden™ ESP processor for silent system designs
and the highly efficient VIA C3™ processor for more demanding multimedia applications.
The mainboard is based on the VIA CLE266 chipset featuring an embedded hardware MPEG-2
accelerator and integrated VIA UniChrome™ 2D/3D graphics for rich digital media performance. With the
sizable memory bandwidth of DDR266 SDRAM and the high data transfer speeds of ATA-133, the VIA
EPIA PD-series delivers the increased performance levels required by today’s commercial digital video
and audio applications.
The latest in high-bandwidth connectivity is supported with up to six USB 2.0 connections, as well as four
COM ports and two 10/100 Fast Ethernet ports for extended broadband connectivity. The VIA EPIA PD-
series also offers support for a number of LVDS embedded LCD panels, has one PCI slot for
expandability options, The VIA EPIA PD-series is compatible with a full range of Mini-ITX chassis as well
as FlexATX and MicroATX enclosures and power supplies.

Noise Level Data
VIA and the EPIA series have been at the forefront of the quiet computing initiative. The VIA EPIA PD-
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 VIA EPIA PD6000E to 25dBA for the VIA EPIA PD10000,
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 fanless thin clients, flat panel small
form factor desktop replacement systems, LCD PCs and a host of other space and power saving systems.
Common Sounds dBA Level
Threshold of hearing 0 dBA
VIA EPIA PD6000E 0 dBA
Normal breathing 10 dBA
Whispering at 1 meter 20 dBA
VIA EPIA PD10000 25 dBA
Conventional PC 35 – 50 dBA
Rainfall 50 dBA
Normal speech 60 dBA
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 Specifications
The EPIA PD utilizes an industry standard 20-pin ATX main connector to the power supply. Due to the
EPIA PD platform’s ultra low power requirements a 90 – 120 Watt ATX power supply is ample for even
the heaviest of multimedia system applications.

VIA EPIA PD-Series Linux & Microsoft Driver Support
Linux Driver Support
The VIA EPIA PD-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 VEPD 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
VIA EPIA PD offers full support for the complete range of Microsoft operating systems.
A Windows XP Embedded support package for VIA EPIA PD 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 CLE266 and
Northbridge as well as integrated audio on the VT8235 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 PD mainboard are also supported in Service Pack 1 (SP1).
