DEC EtherWORKS Turbo Owner's Manual

This document is a comprehensive owner's manual for the DEC EtherWORKS Turbo board, a communications option designed to integrate IBM-AT or compatible personal computers into Ethernet networks. It covers installation, configuration, troubleshooting, and general information about the board.

Key aspects include:

• FCC Notice: Details the board's compliance with FCC Class B limits, potential radio/TV interference, and troubleshooting steps for such issues.
• Installation: Provides a step-by-step guide for preparing the computer, selecting between ThinWire (default) or ThickWire Ethernet via a shunt connector, physically installing the board into a 16-bit option slot, replacing the system unit cover, and connecting to the network. It also mentions a power-up self-test and instructs users to refer to a README.TXT file for software driver installation.

• Configuration: Explains how to adjust the board's 12-switch pack to avoid conflicts with other system components. It details default settings and procedures for changing:

  • Memory Addressing Range and Size (SW1-SW4, default D0000-DFFFF for 64KB).
  • I/O Address Selection (SW5, default 300-30F).
  • Remote Boot Feature (SW6, default disabled, requires optional ROM chip).
  • Remote Boot Period (SW7, default 30 seconds, can be set to 150 seconds).
  • Interrupt Request Line (SW8-SW12, default IRQ5).

• Problem Solving: Offers a "Fault Isolation By Symptom" table listing common problems (e.g., no display, system not booting, network not starting), their possible causes (e.g., conflicts, loose connections, incorrect settings), and recommended actions. It also includes specific self-test error codes and their solutions.

• General Information: Describes the board's physical dimensions, functional components (like the LANCE controller, ThinWire/ThickWire interfaces, network buffer RAM, and an optional remote-boot ROM), an LED indicator, environmental requirements, and detailed system specifications (I/O memory assignments, IRQ lines, power requirements, and operating environment).
• Option ROM Installation: Provides instructions for installing an optional ROM chip, emphasizing precautions against static electricity.

The manual assumes basic familiarity with Ethernet networks and personal computers and encourages users to consult their system administrator for specific settings or issues.
