1.1 About This Manual
This document lists the register settings required for the proper operation of the AMD SP5100
(previously referred to as SB700S). Current sampling of AMD SP5100 is with silicon revision A14
and A15, with the latter being the production part. This document covers settings for prior revision
A12 (used exclusively for SB7xx products) as a reference since the SP5100 CIMx is shared between
SP5100 and SB7xx. CIMx is a software module that helps OEMs to quickly integrate SP5100
support in their products. References to register settings for revision A12 apply only to SB7xx
products. References to register settings for Revision A14, A14 and above, A15, or All Revs apply to
SP5100.
Most of the register settings are mandatory and should be implemented as described in this
document. The document will be updated periodically with new or revised settings that are
determined during the qualification of the SP5100. Please refer to the latest updated document on
the AMD NDA website.
This document should be used in conjunction with the related AMD SP5100 BIOS Developer’s
Guide and the AMD SP5100 Register Reference Guide.
Note: In this document, changes/additions from the previous release are highlighted in red. Refer to
Appendix B: Revision History at the end of this document for a detailed revision history.
