Those who own an older PS3 version and currently run Linux on the console will want to listen up: a new firmware update coming down later this week will kill that installation.

According to Sony, it plans to release PlayStation 3 firmware version 3.21 on Thursday to achieve one goal: eliminate the "Other OS" option currently available in all pre-Slim models of the video game console. The feature allowed PS3 owners to install an operating system--in almost every case, Linux--onto the PlayStation 3.

Sony said that its decision to remove the Other OS option is based on security concerns. The company contends that after installing the update, users will have "a more secure system." Those who currently use the Other OS option and have an operating system running on the PS3 will loss all data (and, obviously, the OS installation) after installing the update.

Although Sony wants PS3 owners to download the software, it said that users won't be forced to do so. That said, if users don't install the firmware, they will lose access to the PlayStation Network and playback of games and Blu-ray movies that require the new software. The console will also stop playing copy-protected content from media servers.
