VIA EPIA-P820 Overview
The VIA EPIA-P820 Pico-ITX mainboard is an ultra compact native x86 platform for a wide range of
embedded system applications. The mainboard is based on the VIA VX855 All-in- ne System
Processor featuring the VIA Chrome™ 9 HCM DX9 IGP with video accelerators for rich digital media
performance.
The VIA EPIA-P820 onboard VIA Nano 1.2 GHz NanoBGA2 processor is a green, secure, and
efficient processor with its included VIA Padlock Security Engine, VIA CoolStream™ Architecture,
VIA StepAhead™ Technology Suite, and VIA TwinTurbo™ technology.
The VIA EPIA-P820 delivers the performance levels with its included sizeable support of up to 2 GB
of 800 MHz DDR2 memory and native support for SATA 3Gb/s storage devices.
The VIA EPIA-P820 is fully compatible with Microsoft
®
and Linux operating systems.
