SteamOS Beta is an early, first-look 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 as you want.
So, what is it not?
As an early release, much is changing, so expect rough edges. In its current state, SteamOS is definitely not a finished product ready for a non-technical user.
Most importantly, it currently only supports a certain set of hardware (you can read more in our FAQ). We are hard at work to expand this list.
That being said, we already use it in our living rooms. We are excited about what it is and what it will become. And the more of you do the same and tell us about your experiences, the quicker those rough edges will be sanded off.
Users should not consider SteamOS as a replacement for their desktop operating system. SteamOS is being designed and optimized for the living room experience.
Default Installation You will need to create a SteamOS System Restore USB stick to perform this install. The image provided here requires at least a 1TB disk.
[li]Download the default SteamOS beta installation Format a 4GB or larger USB stick with the FAT32 filesystem. Use "SYSRESTORE" as the partition name. [li]Unzip the contents of SYSRESTORE.zip to this USB stick to create the System Restore USB stick. [li]Put the System Restore USB stick in your target machine. Boot your machine and tell the BIOS to boot off the stick. (usually something like F8, F11 or F12 will bring up the BIOS boot menu). [li]Make sure you select the UEFI entry, it may look something like "UEFI: Patriot Memory PMAP". If there is no UEFI entry, you may need to enable UEFI support in your BIOS setup. [li]Select "Restore Entire Disk" from the GRUB menu. [li]When it is complete it will shutdown. Power on the machine to boot into your freshly re-imaged SteamOS.
