Device Mapping; Introduction - DEC Digital PC 3500 System Reference Manual

Introduction

This appendix provides a series of tables listing mapping and address information
related to computer memory and various main logic board devices (keyboard
controller, interrupt controller, DMA controller, etc.).
Your computer's memory and address locations are allocated at the factory to
operate within a standard PC environment. However, due to the number of optional
devices and/or expansion boards that are available, sometimes memory and address
locations need to be changed. For example, some network expansion boards
require a specific memory location. If that location is already allocated, a memory
conflict results and the expansion board will not operate as expected. Note that
some memory, I/O and interrupt locations can be changed using the BIOS Setup
utility.
Refer to Chapter 2, "Using the BIOS Setup Utility," for additional information.
CAUTION:
refer to the documentation supplied with the optional device,
expansion board, or software application and make sure
adequate information is available. If not, contact the option or
software manufacturer for further information.
