Introduction
This appendix provides a series of tables listing map and address information related
to server memory and various main logic board devices (such as keyboard controller
and interrupt controller).
Server memory and address locations are allocated at the factory to operate within a
standard 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 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.
