Digital Personal Workstation Quick Reference Guide

This document serves as a quick reference and troubleshooting guide for Digital Personal Workstations, primarily intended for servicing by A+ certified engineers. It covers essential information for the workstation's setup, operation, and maintenance.

Key areas of the document include:

• Product Description: An overview of Digital Personal Workstations, highlighting their high-performance features such as Pentium Pro processors, expandable EDO/Fast-Page Parity memory (up to 256MB/512MB), PCI local bus architecture, video expansion boards, onboard Ethernet, 16-bit stereo audio, and Ultra-Wide SCSI adapters. It details various models, some pre-installed with Windows NT 3.51 or 4.0, and their specific configurations.
• BIOS Setup Utility: Instructions for accessing and configuring the BIOS settings, covering main system options (time, date, disk drives, memory, cache), advanced features (COM/LPT ports, large disk access, integrated Ethernet), security (passwords), power management, and boot sequence. It also describes the Flash Utility for BIOS updates.
• System Software: Information on factory-installed software (Windows NT Workstation, device drivers, utilities like Adobe Acrobat Reader and ClientWORKS), the operating system kit, and backup CD-ROM/diskettes. It outlines procedures for configuring video, networking, and additional hardware, using diagnostic software, and restoring the workstation's software.
• Troubleshooting: An extensive section providing initial troubleshooting steps, pass/fail criteria for POST tests, and detailed problem/possible cause/action tables for various components including the workstation itself, disk drives (IDE/SCSI, diskette), monitor, audio, network interface, and CD-ROM. It also lists and explains POST error messages and beep codes for diagnosing issues.
• Parts List: Comprehensive lists of Field Replaceable Units (FRUs) for the workstation's enclosure, storage devices, video and SCSI adapter cards, cables, and miscellaneous items.
• Workstation Components: Identification and description of main logic board components, rear panel connectors, backplane components, expansion slot locations, main logic board jumper and switch settings (including CPU bus speed), and detailed memory installation and configuration guidelines for EDO and Fast-Page Parity SIMMs.
• Device Mapping: Tables outlining technical specifications such as the full-range processor memory address map, I/O address map, interrupt levels, and DMA channel assignments, noting that some of these can be modified via the BIOS Setup utility.

The document also includes regulatory information from the FCC regarding interference and important safety warnings concerning battery replacement and disposal.
