The new location is https://github.com/psanford/mirabox. I've turned it into a full git repository so that it is easier for others to contribute. This gist will not be updated anymore and I won't be checking the comments. Please open an issue or a pull request on the git repo.
There's not a lot of good documentation about Globalscale Technology's [Mirabox][1] so this page is intended to document everything I know about it. My goal is to run a modern kernel and bootloader on the Mirabox.
