The Linux Kit turns the PlayStation 2 into a full-fledged computer system, but it does not allow for use of the DVD-ROM drive except to read PS1 and PS2 discs due to piracy concerns by Sony. Although the HDD included with the Linux Kit is not compatible with PlayStation 2 games, reformatting the HDD with the utility disc provided with the retail HDD enables use with PlayStation 2 games but erases PS2 Linux, though there is a driver that allows PS2 Linux to operate once copied onto the APA partition created by the utility disc. The Network Adapter included with the kit only supports Ethernet; a driver  is available to enable modem support if the retail Network Adapter (which includes a built-in V.90 modem) is used. The kit supports display on RGB monitors (with sync-on-green) using a VGA cable provided with the Linux Kit, or television sets with the normal cable included with the PlayStation 2 unit.
The PS2 Linux distribution is based on {{ill|Kondara MNU/Linux|ja}}, a Japanese distribution itself based on [[Software:Red Hat Linux|Red Hat Linux]]. PS2 Linux is similar to Red Hat Linux 6, and has most of the features one might expect in a Red Hat Linux 6 system. The stock kernel is Linux 2.2.1 (although it includes the USB drivers from Linux 2.2.18 to support the keyboard and mouse), but it can be upgraded to a newer version such as 2.2.21, 2.2.26 or 2.4.17.
== Open-source applications ==
[[Image:Ps2 linux contents.jpg|thumb|200px|Contents of the Linux kit; the hard disk is already installed inside the machine, and the network adaptor is attached to the back.]]
The Linux kit's primary purpose is amateur [[Software development|software development]], but it can be used as one would use any other computer, although the small amount of memory in the PS2 (32MB) limits its applications. Noted [[Open-source software|open source]] software that compiles on the kit includes Mozilla Suite, [[Software:XChat|XChat]], and [[Software:Pidgin|Pidgin]]. Lightweight applications better suited to the PS2's 32MB of RAM include [[Software:Xv|xv]], [[Software:Dillo|Dillo]], [[Software:Ted (word processor)|Ted]], and [[Software:AbiWord|AbiWord]]. The default window manager is [[Software:Window Maker|Window Maker]], but it is possible to install and use [[Software:Fluxbox|Fluxbox]] and [[Software:FVWM|FVWM]]. The USB ports of the console can be connected to external devices, such as printers, [[Physics:Camera|camera]]s, [[Engineering:USB flash drive|flash drive]]s, and [[Engineering:Compact disc|CD]] drives.
With PS2 Linux, a user can program their own games that will work under PS2 Linux, but not on an unmodified PlayStation 2. Free open source code for games are available for download from PS2 Linux support sites. There is little difference between PS2 Linux and the Linux software used on the more expensive system ("Tool", DTL-T10000) used by professional licensed PlayStation game programmers. Some amateur-created games are submitted to a competition such as the Independent Games Festival's annual competition. It is possible for an amateur to sell games or software that they develop using PS2 Linux, with certain restrictions detailed in the End User License Agreement. The amateur cannot make and sell game CDs and DVDs, but can sell the game through an online download.

== Model compatibility ==
The original version of the PS2 Linux kit worked on only the Japanese SCPH-10000, SCPH-15000 and SCPH-18000 PlayStation 2 models. It came with a PCMCIA interface card which had a 10/100 Ethernet port and an external IDE hard drive enclosure (as there is no room inside the unit). This kit cannot be used with any later model PS2 (which includes all non-Japanese models) because these models removed the PCMCIA port.
 
Later versions of the PS2 Linux kit use an interface very similar to the HDD interface/Ethernet sold later for network play (the later released Network adaptor was also usable with the kit, including the built-in 56k modem.) This kit locates the hard drive internal to the PS2, in the MultiBay. With this kit, only the SCPH-30000 model of PlayStation 2 is officially supported. The kit does though work equally well with models newer than SCPH-30000 with the exception that the Ethernet connection tended to freeze after a short period of use. Thus the newer SCPH-50000 PlayStation 2 model will only work correctly with PS2 Linux with an updated network adapter driver, which must be transferred to the PlayStation 2 HDD by using either an older model PlayStation 2 to transfer the driver or a Linux PC with an IDE port. Both methods involve swapping HDDs. This is due to the inability to use USB Mass Storage devices with the relatively old kernel (version 2.2.1) shipped with the kit.
 
The slim SCPH-70000 PlayStation 2 model does not work with PS2 Linux at all, due to the lack of a hard drive interface, though a very few early models in this revision had solder pads of an IDE interface on the motherboard that could be used (but required modding of the console, thereby voiding its warranty.) Even so, it is possible to network boot from a PXE server.
 
PS2 Linux installation DVDs are region encoded, as are all other PS2 game discs. A European/PAL disc will be rejected by an NTSC PlayStation 2 game system; however this is only at boot time: if the user has a mod that allows them to load a PAL disc, then the PS2 Linux boot loader supports both PAL and NTSC Linux (read the documentation to determine the button presses), so once they are past the "DVD not supported", they can boot Linux and then later start X Window in NTSC mode.
 
== Unofficial support ==
Ever since the discontinuation of the PS2 Linux Kit and some time before that there has been a large, less active group who have tried and succeeded to run the Linux operating system through other methods, most notably using the [https://kernelloader.sourceforge.net/linux.html KernelLoader] Linux loader developed by Mega Man since 2008 where they have copied the necessary kernel files onto removable storage or DVDs formatted as Video DVDs due to Sony's anti-piracy efforts which restrict any data DVDs and loaded them through the program.
 
Through this method it has become possible to use custom Linux distros and other UNIX-like<ref>{{cite web |title=NetBSD port to the PlayStation 2, with references to how KernelLoader could be used to free it from Sony's HAL. |url=http://www.uk.netbsd.org/ports/playstation2/ |access-date=11 January 2024}}</ref> operating systems compiled for the PlayStation 2 and this has enabled users to use more compatible Linux kernels with smaller footprints and programs specially designed for the console. [https://www.psx-place.com/resources/ps2-linux-live-dvd.860/ These methods often] require the use of PS2 exploits such as Free MCBoot which allows the end user to boot from the PlayStation 2 memory card and launch custom made homebrew applications packaged as ELF files and other exploits such as SwapMagic etc. however these tend to void the warranty as some require the opening of the PlayStation 2 console itself.

Linux for PlayStation 2 (or PS2 Linux) is a kit released by Sony Computer Entertainment in 2002 that allows the PlayStation 2 console to be used as a personal computer. It included a Linux-based operating system, a USB keyboard and mouse, a VGA adapter, a PS2 network adapter (Ethernet only), and a 40 GB hard disk drive (HDD). An 8 MB memory card is required; it must be formatted during installation, erasing all data previously saved on it, though afterwards the remaining space may be used for savegames. It is strongly recommended that a user of Linux for PlayStation 2 have some basic knowledge of Linux before installing and using it, due to the command-line interface for installation.

The official site for the project was closed at the end of October 2009[1] and communities like ps2dev[2] are no longer active.

Distribution

This kit has stopped being officially sold in the US as of 2003 due to the entire allocation of NTSC kits selling out. However, it is still available through some second-hand markets, such as eBay. Some incorrectly speculate that it was used as an attempt to help classify the PS2 as a computer in order 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).[3] Despite this, Sony lost the case in June 2006. The kit was released in the spirit of the earlier Net Yaroze. PlayStation and Sony ended their support of hobbyist programmers with the support of Linux on the PlayStation 3 being discontinued.
