PS3 Linux
Originally Sony stated that they were going to pre-install Linux on the PS3's hard drive, but current units shipping do not include Linux preinstalled. Instead, Sony has made an option in the XMB menu to install other operating systems. Installation of an operating system is achieved by going to Settings > System Settings > Install Other OS. When installation is complete, the startup operating system can be changed.[65] Sony has set up a web page which will list compatible operating systems.[4]
On October 17, 2006, a month before the console release, Terrasoft announced a version of Yellow Dog Linux for PlayStation 3.[66] Terrasoft will be using the PS3 for their own supercomputing clusters as well. Yellow Dog Linux 5.0 is already listed in Terrasoft's store, for US$50 including a printed manual and DVDs for sources and pre-compiled applications;[67] the applications include recent versions of the Linux kernel, the GNU Compiler Collection, Firefox, and OpenOffice.org.[68] According to Ars Technica, Yellow Dog Linux 5.0 will be made publicly available two weeks after the console's launch. Terrasoft stated the installer "enables absolutely anyone to install without instruction." Yellow Dog Linux 5.0 integrates code from the Barcelona Supercomputing Center, Sony, and Red Hat's Fedora Core 5.
