Valve released SteamOS last year – it seemed amazing at the time, a clear change for PC gaming – but be careful, it contained a warning. Use at your own risk. You better know what you’re up to.
Whilst this allowed for the ‘true’ developers to get their hands on it, SteamOS still required new machines with UEFI to be used.
However a second beta now allows dual booting, to overcome several issues around support and dedicated hardware. While also flouting partition, recovery and DVD install support.
Gabe’s on a roll and, it looks like nobody will stop him (and Steam) taking over the PC market.
