Step seven: Plug the controller in, hit the Play Station button, and select the "Update System Software" option.
After a few minutes and a couple of restarts, your Play Station 4 should be up to date.
The USB ports of the console can be connected to external devices, such as printers, cameras, flash drives, and CD drives.
With PS2 Linux, a user can program their own games that will work under PS2 Linux, but not on an unmodified Play Station 2.
The latter can be utilized for those who don't have an Internet connection readily available.
Step six: Boot the Play Station 4 in safe mode by holding the power button for 7 seconds.
Step eight: To ensure the update was properly installed, enter Settings, click on System Settings, and select System Information.
Linux for Play Station 2 (or PS2 Linux) is a kit released by Sony Computer Entertainment in 2002 that allows the Play Station 2 console to be used as a personal computer.
Some incorrectly speculate it was used as an attempt to help classify the PS2 as a computer to achieve tax exempt status from certain EU taxes that apply to game consoles and not computers (It was the Yabasic included with EU units that was intended to do that). The kit was released in the spirit of the earlier Net Yaroze.
Play Station and Sony ended their support of hobbyist programmers with the support of Linux on the Play Station 3 being discontinued.
It is strongly recommended that a user of Linux for Play Station 2 have some basic knowledge of Linux before installing and using it, due to the command-line interface for installation.
