Digital Network Appliance Reference Design

This user's guide provides comprehensive information for the Digital Network Appliance Reference Design (DNARD), a development platform based on the 233-MHz StrongARM processor. The document is structured into three main areas:

• Introduction and Overview: Describes the DNARD hardware/software package, which includes the board, industrial enclosure, cables, and a development software stack (NetBSD, XFree86, Java). It explains the development-to-production strategy, recommending transition to the NC Desktop software for final products.
• FreeBSD Installation and Setup: Provides step-by-step instructions for installing and configuring FreeBSD on a PC to function as a network server for DNARD units, including kernel customization for DHCP server support and building the root file system using the NCBootServerConfig utility.
• Hardware Functional Description: Details the core hardware architecture, including the CPU, memory (SDRAM) subsystem, video, ROMcard, clocks, and the Sequoia core-logic chip set. It also covers the integration of I/O interfaces such as the Super I/O device, smart card, and consumer IR logic.

The guide concludes with support and documentation resources for developers using this reference design for network computer applications.

Important Note: The DNARD board is intended strictly for the evaluation and development of network computer solutions and is not intended for inclusion in final consumer products.
