This repo has moved to the GitHub corner of the current maintainer Lee Binder because I gave my VivoBook away and he still runs his as a hackintosh. You can find the latest version there:
LeeBinder / Asus-Vivobook-S510UA-Hackintosh
For the purpose of providing an archive, you can still download the two previous releases from this repo's release section.
