OtherOS

OtherOS is a term used to describe a feature once offered by Sony for the PlayStation 3 that allowed users to install and run alternate operating systems, most notably Linux, on the console hardware. The feature was presented as a way to repurpose the PS3’s hardware for general computing, education, and research, expanding the device beyond a video game console.

Functionality and use. OtherOS provided an option in the PlayStation 3’s system menu to install a separate operating system on a dedicated portion of the hard drive and, in some cases, from external media. Once installed, users could boot into Linux or other supported distributions, using the console’s Cell processor and memory for computing tasks. The setup was popular among hobbyists and researchers who valued access to a multi-core architecture and large memory for experiments, development, or learning.

Removal and controversy. In 2010, Sony removed the ability to enable OtherOS through a firmware update, citing security and anti-tampering concerns. The change sparked substantial user backlash and led to legal action in various regions, with settlements reached in some cases that offered compensation to affected users. After the removal, the feature was not reintroduced in later official firmware updates, and most PS3 hardware revisions no longer supported OtherOS.

Legacy. OtherOS is historically significant for illustrating debates over openness versus security in consumer devices. It demonstrated that game consoles could be repurposed for broader computing tasks, while also highlighting challenges related to platform security, vendor control, and consumer rights. The feature remains a notable episode in the history of Linux on consoles.
