Okay I found this over on reddit. I did down load and look them over however I have never had much luck using the editors since R9 290. But here we go. I did download and keep store the download including the "source" in case the post there vanishes. I can put on googledrive if needed. I did take a quick look at the editor using the 2 bios available on tech powerpup for the RX 480. Reddit post by the "author" of this : https://www.reddit.com/r/Amd/comments/4qu9y0/polaris_bios_editor/ So here you go: Download: http://puu.sh/pN3A5/6bd0958cee.zip Supposed source code: http://puu.sh/pN4Vk/1f4243a194.zip Warning pic it gives: Pic with both RX 480 bios from techpowerup database. I did try to load my own R9 290 bios and get an error. It also fails to read a fury bios I downloaded.
