Does this mean I can install SteamOS on any device?

We expect most SteamOS users to get SteamOS preinstalled on a Steam Deck or device that incorporates SteamOS. The only devices officially supported on SteamOS right now are Steam Deck and Legion Go S. We are working on broadening support, and with the recent updates to Steam and SteamOS, compatibility with other AMD powered PC handhelds has been improved. If you are interested in trying out SteamOS on your device and providing feedback, you can use the SteamOS Recovery Image

Users should not consider SteamOS as a replacement for their desktop operating system.
