Enthusiast hacks Valve’s AMD-first gaming OS to run on Intel hardware — SteamOS boots on Intel Arc B580 desktop GPU, but it takes a Radeon card, installer workaround, and Resizable BAR fix
A Reddit user has successfully booted and run Valve's SteamOS, an operating system primarily designed for AMD hardware, on an Intel Arc B580 desktop GPU. This achievement required a workaround for the installer, the use of a separate AMD Radeon card during the initial setup, and specific motherboard settings. While the SteamOS interface and basic functionality worked, initial gaming performance was poor, but significantly improved after enabling Resizable BAR, though it still did not fully match Windows performance benchmarks.
