The "Other OS" feature is disabled by firmware version 3.21 but still runs on older consoles that have firmware 3.15 or lower.
Since 2000, Sony has used the fact that the Play Station 2 can run Linux in its marketing.Sorry for the long delay in updating this site as I had a personal problem to take care of.So bare with me as I try to bring this site upto date with the latest news from the homebrew community .Other OS was a feature available in early versions of the Play Station 3 video game console that allowed other operating systems, such as Linux or Free BSD, to be installed on the system.This feature was made unavailable in newer models and removed from the oldest ones through a firmware update by Sony.They promoted the release of the PS2 Linux Kit, which included a Linux-based operating system, a USB keyboard and mouse, a VGA adapter, a Play Station 2 Ethernet network adapter, and a 40 GB hard disk drive (HDD).
The Play Station 3 does not have Linux pre-installed.
However, Sony included an option in the XMB menu soon after the Play Station 3 launched that allowed booting into Linux from the hard drive or from a Live CD that the distributor's kernel would boot.
