Introduction This document defines Mini-ITX, the IT industry’s smallest form factor mainboard specification, developed by VIA Technologies, Inc. As part of the company’s open industry- wide Total Connectivity initiative, the new VIA Mini-ITX mainboard enables the creation of an exciting new generation of small, ergonomic, innovative and affordable embedded systems through its high level of integration and vastly reduced size of less than 33% the size of the FlexATX mainboard form factor. The new Mini-ITX mainboard comes with an onboard VIA Eden™ Embedded System Platform or a VIA C3™ E-series processor, boasting high levels of integration, ultra low power consumption and cool, quiet operation providing a noiseless and more ergonomic system. A platform for innovation due to its small size and onboard VIA Eden™ Platform, the Mini-ITX is fully compatible with Microsoft ? Windows ? XP and a full range of Embedded Windows, Windows CE, and the latest Linux operating systems and applications. Compatibility is further enhanced with its support for all the most popular Internet programs and plug-ins. The new VIA Eden™ Embedded System Platform is spurring the further development of the emerging new generation of quiet running, low profile small factor designs that are being adopted for a myriad of connected information and entertainment systems – ranging from home entertainment devices such as Set Top Boxes, Game Consoles, Personal Video Recorders and Broadband Gateways to commercial applications such as Thin Clients, LCD Web Based Terminals, POS Terminals, and Network Attached Servers. These new designs not only leverage the fundamental strengths of the x86 platform – namely, its software resources, its Internet compatibility, its rapid product innovation cycles, its massive economies of scale and its open architecture. They also extend the capabilities of the PC and the Internet by allowing people to connect to information and entertainment in an easier, more convenient, and more affordable way. Compact, stylish, reliable, fanless, and energy efficient, these new devices are already beginning appearing in homes, workplaces, and public places such as airports and coffee shops, and are set to further proliferate as more compelling digital multimedia applications and services are developed and delivered over the Internet, home
