The best way is to search by document ID if you have it. Many of our technical documents have very similar names.
WIthout the ID, phrases that might help your search include:
* Register Reference Guide
* BKDG - (BIOS and Kernel Development Guide)
* Software Optimization Guide
These are organized typically by processor family, not by code name (e.g. Kabini). You can find a reasonably good decoder ring for which code name = which family here: List of AMD CPU microarchitectures
