SteamOS is the currently-in-beta Linux-based operating system that will power Valve’s new gaming-PCs-turned-consoles. While the Steam crew has been busy readying 300 beta Steam Machines, they’ve taken the time to release the code for download by Linux enthusiasts. As they describe it,
SteamOS Beta is the first public release of our Linux-based operating system. The base system draws from Debian 7, code named Debian Wheezy. Our work builds on top of the solid Debian core and optimizes it for a living room experience. Most of all, it is an open Linux platform that leaves you in full control. You can take charge of your system and install new software or content that you want.
SteamOS hardware requirements:
Processor: Intel or AMD 64-bit capable processor
Memory: 4GB or more RAM
Hard Drive: 500GB or larger disk
Video Card: NVIDIA graphics card
(AMD and Intel graphics support coming soon!)
UEFI boot support
USB port for installation
