The AMD DMG is for post install assistance for AMD CPU based systems. Everything you will need is provided on the DMG. There is no extra files or fancy tricks just the basics so that your system is fully functional and stable. What I need from AMD users is DSDT and IOreg Extract with BIOS version. Please post your files here.
If you do not know how to obtain these files I have guides that can be found here:
The SSDT table on the DMG is the most important item. This has patches and fixes for your system allowing you to gain full functionality. Please only use these files after a clean install.
