Introduction
This chapter 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.).
The 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.
CAUTION:
Before changing any memory or address
location, 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.
