I followed the instructions from this thread (used the dropbox link), and unzipped the file into the newly made hardware folder. Then restarted Arduino and selected the new board, as instructed.
The error said it was looking for BlinkBIOS.hex in that folder, here are the files in the bootloaders folder:
The only other thing I’m noticing out of place is there is a _MacOSX Folder that was unzipped as well, but I am on Windows, but the file path didn’t seem to go that direction anyway, so I’m thinking that is irrelevant.
