Information about specific changes in each osboot release, can be found at docs/release.html

The Git repository is recommended if you want the most up to date version, but you will have to build it from source. Git is preferred for development.

https://notabug.org/osboot/osbmk/

If you wish to compile osboot from source code, refer to this guide for how to compile osboot source code. Information about the build system is available on the osboot Maintainance Manual.

Download pre-compiled releases (recommended for most people)

The 20210205 release was deleted. Please build from Git for now; a new beta release will be available soon. See above for instructions on how to compile osboot.

NOTE: osboot used to be called retroboot. It was renamed, because the old name wasn’t very good. Some of the links below still say retroboot, because they existed prior to the name change. The old rsync link will still work aswell (but there is also now a new rsync address on this page).

Download osboot releases from one of these mirrors:

https://mirrors.qorg11.net/retroboot (server location: Spain)

https://mirrors.freedragon.ml/osboot/ (server location: Hong Kong)

https://mirrors.0gitnick.xyz/osboot/ (server location: Poland)

Be sure to verify the GPG signature! (see below)

osboot is looking for people to provide download mirrors. See Rsync info on this page.

These links are not https, but plain http is OK for Tor sites. These links only work in Tor Browser.

GPG signing key

Releases are signed with GPG. This means that you can verify whether you have the correct archive and that it has not been tampered with. The following key is available for the purpose, listed on public key servers.

Download the key in GNU+Linux:

gpg --recv-keys 0xD0C62464FA8B4856

Full key fingerprint: 98CC DDF8 E560 47F4 75C0 44BD D0C6 2464 FA8B 4856

When you’ve followed the above instruction, you have the key. This can be used to verify the authenticity of archives that you have downloaded (or at the very least, ensure that they were provided officially by the osboot project). All releases are signed with this key, including beta releases.

When you download osboot, an accompanying .sig file will be available with every file. For instance, osboot20210205beta_src.tar.xz will also have a file named osboot20210205beta_src.tar.xz.sig available.

Verify the GPG signature on a source code archive:

gpg --verify osbootVERSION_src.tar.xz.sig

Verify the GPG signature on a ROM archive:

gpg --verify osbootVERSION_rom_archive.tar.xz.sig

Do you have a mirror?

Let us know! We will add it here.

If you wish to create a new mirror of the osboot releases, you can use rsync. See: rsync mirror list.

RSYNC mirrors

Useful for mirroring osboot’s entire set of release archives. You can put an rsync command into crontab and pull the files into a directory on your web server.

It is highly recommended that you use the osboot.org mirror, if you wish to host an official mirror. Otherwise, if you simply want to create your own local mirror, you should use one of the other mirrors, which sync from osboot.org.

rsync://rsync.osboot.org/osboot/ (osboot.org official mirror, UK)

rsync://mirrors.freedragon.ml/osboot/ (server location: Hong Kong)

Are you running a mirror? Contact the osboot project, and the link will be added to this page!

If you want to create a mirror, first create a directory in the webroot of the directory for your website.

To automatically update your mirror, add this in your crontab:

rsync -avz --delete-after rsync://rsync.osboot.org/osboot/ /path/to/your/directory/

NOTE: The final / on /path/to/your/directory/ is very important. The --delete-after parameter is also very important.

Now, verify that the files appear on your URL e.g. https://foo.com/osboot/

NOTE: We only link to https and rsync mirrors. Unencrypted HTTP mirrors will not be linked here (encrypted rsync mirrors are not possible, but releases have GPG keys included with them, which mitigates this)
