Revision History Revision Description Revision Date Number -001 Initial release. June 2008 § White Paper 5 6 White Paper Introduction 1 Introduction The basic computing market segment is commonly considered a simplified PC solution at a system price point of $299 USD and below. These computers are part of a new family of computers; called “nettops”, which represent a new generation of low-cost PCs running on Intel processors. These systems are targeted at users in both mature and emerging market segments whose computing needs and price points require focused and targeted system solutions. With a small form-factor ideal for young kids and designed to be affordable to first- time users, nettops are configured to run less demanding applications. This white paper provides a guideline for building a nettop platform for the worldwide sub-entry market segment using the Intel® Desktop Board D945GCLF with the Intel® Atom™ processor 200 series. This product is Intel’s targeted solution for this marketplace. 1.1 Scope This document consolidates architectural requirements and specifications for delivering a low cost client platform. This document does NOT: • Repeat information readily available in standard specifications, but it will reference them. • Address warranty, distribution costs, tariffs, price, or any other financial or legal terms and conditions. 1.2 Audience The target audience for this document includes: • OEMs, platform designers and integrators seeking
