Digital Personal Workstations System Reference

This document is a comprehensive system reference guide for Digital Personal Workstations (models 180i, 200i, 200i², 266i, and 266i²), published in April 1997 by Digital Equipment Corporation. It is intended for users responsible for configuring and expanding their workstations.

The guide covers:

• Initial Setup & External Connections: Details front and rear panel components, indicators, and connectors. It provides instructions for physically securing the workstation, connecting external devices like speakers, headphones, microphones, MIDI/joystick devices, printers, and Universal Serial Bus (USB) devices, and using the Windows enhanced keyboard. It also includes instructions for removing and replacing the front bezel door and creating an ergonomic working environment.
• BIOS Setup Utility: Explains how to access and use the BIOS Setup utility to configure various workstation settings, including time and date, security (supervisor and user passwords, boot password, boot sector virus protection), power management options, and diskette and IDE hard disk drive configurations. It also touches on the Flash Utility for BIOS updates.
• Internal Components & Upgrades: Provides descriptions and locations of internal components such as the main logic board and backplane. It details procedures for improving workstation performance by installing additional memory, upgrading hard disk drives, replacing the lithium battery, and installing higher-performance Pentium-Pro or Pentium II processors.
• Expansion & Storage: Gives instructions for adding ISA and PCI expansion boards and various mass storage devices (3½-inch and 5¼-inch devices, diskette, IDE, and SCSI devices), including cabling guidelines.
• Technical Specifications: Lists vital operating and performance specifications, including processor features (cache, network, audio), DRAM types and capacities, physical dimensions, environmental conditions, power supply requirements, and main logic board jumper and switch settings for various configurations and troubleshooting (e.g., password clear, recovery mode).
• Device Mapping: Provides tables for memory address, I/O address, interrupt levels, and DMA channel assignments.
• Glossary: Defines key technical terms used throughout the document.

The document emphasizes safety warnings, particularly regarding static electricity and lithium battery replacement, and notes that certain features or operating system functionalities may vary or require specific BIOS updates (e.g., USB support, Windows NT power management).
