OpenIndiana works on most PCs (help us support SPARC). All downloads support both 32-bit and 64-bit processors: 64-bit mode is automatically selected if at least 900 megabytes of memory (RAM) are available.
From 2017.04 onwards running on 32-bit systems is not supported anymore and the userland is being migrated progressively to 64-bit only. As usual 32-bit libraries and core applications are still delivered and maintained for the sake of backward compatibility (but only when running a 64-bit kernel).
For instructions regarding downloading, preparing and installing the images, please refer to the OpenIndiana Handbook.

These installations can be updated regularly using the Hipster repository, and receive security fixes. Starting with 2017.04 release, every image is signed with OpenIndiana Release Engineering GPG key id DBE31887.
