Introduction
This chapter 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.).
The 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.
