Device Mapping
Introduction
This appendix provides a series of tables listing map and address
information related to server memory and various main logic board
devices (keyboard controller, interrupt controller, DMA controller, etc.).
Your 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 SCU.
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.
