 +Microsoft's idea of "taking a cue" from Sony to enter the video games market. Releasing on November 15th, 2001 in North America, the Xbox's specifications boil down to a custom Pentium III CPU, 64 MB of RAM (upgradable with modding), and GeForce 3 based graphics capable of outputting up to 1920x1080(!!) with presumably >24-bit true color. These were very powerful for the time, and essentially equated to a desktop PC crammed into a console's form factor. Combined with a strong games library and powerful modding scene, the Xbox ended up selling 24 million units, complete with a record-breaking launch sales figure of 1.5 million - making it enough of a success (despite monetary losses at Microsoft) to afford the release of a successor device.

-Levels of function unknown, but it boots and has text interfacing.+One of the more obscure OSes ported to the Xbox. Darwin is in essence, Apple's FOSS component within Mac OS X, or in other words, the parts of OS X's kernel that Apple release to the public. While capable of running as an independent OS, certain proprietary blobs within OS X itself makes it so Darwin is not just "FOSS OS X", but rather an "alternative" way to use Apple's code. As for the port itself, it is limited due to the obscure nature of the OS. Only Darwin 8.0.1 (base of OS X 10.4) is supported, and it requires a 128 MB RAM Xbox. While it does boot in some capacity, further levels of functionality are unknown and may be limited.

-liveCD based distro with official Xbox support, among others.+An old liveCD based distro with official Xbox support, among others. At the time, it was optimized to run on weaker hardware, with 1.4.1 seemingly being the most recent version to support it. The front page advertises creating "clusters" of Xboxes running this distro, which sounds intriguing.

-Fedora Core for the Xbox.+Fedorathe classic distro in it's "core" form, on Xbox. Installation is purportedly quite easy, requiring only a disc, HTTP server, and a method of input. Very few "Xbox-specific" patches are required in Fedora to make it work, which makes this port of Fedora function quite similarly to an average PC port.

As of 2022, one can still see the xbox page on the main FreeBSD website, with it claiming that FreeBSD has supported Xbox since version 6's stable release. It is important to note that an up-to-date Cromwell BIOS is required to make this work.

-The “other” seemingly prestige linux distro for Xbox. Custom tailored for Xbox.+One of the higher quality Linux distributions available for the Xbox. As apparent from the name, this is a fork of Gentoo. Unlike the original Gentoo, however, GentooX is loaded with patches and modifications to make it highly optimized for the Xbox's hardware. Among the many unique features it possesses, is a custom patching and package installation program, various methods of installing (partitions), and varying editions of the OS depending on one's needs (all are free, of course). To be specific, there is a "Home", "Media Center", and "Pro" edition. The "Home" edition is likely of interest to most, as it comes loaded with programs and works out of the box. "Media Center" is quite self explanatory in it's addition of media center functionality, while "Pro" comes as only a command line, allowing the user to customize the install to the fullest if they wistNot to be confused with the GentooX repository on GitHub!

ReactOS itself is a FOSS attempt of replacing Windows, with their goal being to create an OS that can run any Windows program up to a certain point, without depending on any Windows modules or libraries that they haven't recreated themselves. As for the Xbox port, well, it boots, works, and actually functions in a significant capacity. Of course, ReactOS itself is not finished, so this does mean that things are still quite incomplete, with much of the hardware not having any drivers. Installation is possible, alongside running a Live CD.

Similar to sXb, DSL is a very small distro, coming in at only around 50 MB, yet it is loaded with programs and capabilities, like a web browser, an IRC client, an email client, office programs, and much more, all in a graphical environment. When looking at the sourceforge page, retrospective looks at Xbox Linux, and just general popularity, it seems that X-DSL could be the most popular distro for Xbox too. The only downside is that 1.6 version Xboxes may have troubles with running it. A Live CD is also available for this distro.

 +For general information, see the [[eop:essays:game_console_revisions_overview|Game Console Revisions Overview]].
 +
 +Huge thanks to the **[[https://consolemods.org/wiki/Xbox:Original_Xbox_Mods_Wiki|ConsoleMods.org Xbox Wiki]]** for supplying a lot of this information. They're in the sidebar for a reason!
 +
 +
 +==== Versions ====
 +
 +//There is one version of this console.//
 +
 +=== “Xbox” (2001-2009) ===
 +
 +The first Xbox console. 4 controller ports up front, a power button and DVD drive. AC, Ethernet, and AV to the back, with a hard drive inside. This setup stayed the same across the Xbox’s life, with the only external change being to the DVD drive’s tray. This is important, as it allows the user to identify which DVD drive it is. Thomson: U shape. Phillips: U, with a wider-than-U circle at the tray’s center. Samsung: weird “U” with angles on the left/right, plus two large nearby circles. Hitachi: wide “U” with two small distant circles to the left/right. One can check the excellent /r/originalxbox/wiki/revision link for a visual guide. Generally, the Thomsons suck, the Samsungs were well regarded (ish), the Phillips should be OK, and the Hitachis are in 1.6s only, but might be OK. Remember, you can swap DVD drives, sometimes from other devices (PC DVD drives, for example), as the stock ones are all hit-or-miss in quality and reliability.
 +
 +
 +==== Revisions ====
 +
 +//There are five revisions within the Xbox.//
 +
 +=== Xbox revisions: ===
 +
 +//Quick guideline for identifying DVD drives//
 +
 +https://xboxdevwiki.net/File:Xbox_drivedetermination.png
 +
 +Thomson (the worst - 1.0 and 1.1 only): Long "U" shape, like the end of a hotdog
 +
 +Phillips (probably the best - 1.1 and later): Fat "U" shape, with a visible circle at the end - like a bedpost
 +
 +Samsung (also very good - all): 2 smaller circles to the left and right of the main cut out, with the main cut out being asymmetrical on the left/right axis
 +
 +Hitachi-LG (alright - 1.6 only?): Very fat "U" shape with NO visible circle at the end, plus two very small circles to the left and right of the main cutout
 +
 +=== “Xbox 1.0” (2001-2002) ===
 +
 +Likely the least reliable Xbox revision, but it’s one of the best for EOPs. These systems feature a GPU fan, a bad "Foxlink" PSU which is prone to spontaneous and bombastic failure, and a high chance to have the worst DVD drive of all Xboxes, the Thomson (stock 1.0s can only have Thomsons or Samsungs). However, they feature the Conexant video encoder, which is seemingly the best quality over component (don’t use RGB, 480i res cap). They also have a 1MB TSOP chip, which is where the BIOS is located. A 1MB TSOP chip allows more versatility in flashing a new BIOS, although this also can be done on a modchip. Lastly, there’s open RAM slots, which allows upgrading up to 256MB (from 64). Remember, this rev has the leaky clock capacitors (as for the others except 1.6/some 1.4s). Overall, the reliability of these may be poor, but most of the weak parts (DVD, fan, PSU, caps) can be replaced. For EOPs, they’re quite great. To identify: Manufactured from 01/01/2001 - 07/31/2002. Serial number: LNNNNNN 20/21/23XXX (only the 2nd part matters; some 23s are 1.1). Kernel versions 3944, 4034, 4036, and 4627. 
 +
 +
 +
 +=== “Xbox 1.1” (2002-2003) ===
 +//RECOMMENDED OVERALL//
 +
 +For the most part, these are similar to the 1.0, except the GPU fan is gone, the DVD drive can be better (with the introduction of Phillips drives), the PSU has received //some// improvement (still - be wary of it), and the USB controller isn’t a separate PCB. In other words, these have the Conexant, a 1MB TSOP, and the additional RAM slots. Plus, they’re a bit quieter and cooler than the 1.0s. This makes these systems one of the best for EOPs. Remember to swap the leaky clock capacitors! Furthermore, beware of the Foxlink PSUs which can fail very bombastically and spontaneously, although this is a bigger issue in 1.0 Xboxes. To identify: Manuf. 08/18/2002 – 01/25/2003. Serial 2nd half starts with 23-25. Kernel either 4817 or 4972.
 +
 +
 +=== “Xbox 1.2/1.3” (2003) ===
 +
 +With these systems, some things have changed significantly, mainly the TSOP shrinking to 256KB. The PSU is also a more conventional ATX type, making replacement easier. Not much else is different, although they are a bit quieter and cooler than the 1.1s. RAM can still be added, as for the ability to modchip. The 1.3’s are identical, except one irrelevant LPC pin has been removed. Remember to swap the leaky clock capacitors! To identify: Manuf. 12/01/2002 – 07/26/2003. Serial 2nd half starts with 30-32. Kernel either 5101, 5530, or 5713 (shared with 1.4/1.5s).
 +
 +
 +
 +=== “Xbox 1.4/1.5” (2003-2004) ===
 +
 +More has changed with these systems, and they don’t appear to be good changes. First of all, the TSOP is still 256KB. The video encoder has been changed to the Focus encoder, which doesn’t have the best reputation (although some may prefer it). Furthermore, modchips and RAM additions both will work. Also, many of these will not have the leaky clock capacitors, but check anyways. 1.5s most likely don’t exist, and if they were produced, it was only for a very short period of time. To identify: Manuf. 07/23/2003 – 04/10/2004. Serial 2nd half starts with 33. Kernel either 5101, 5530, or 5713 (shared with 1.2/1.3s).
 +
 +
 +
 +=== “Xbox 1.6 (a/b)” (2004-2009?) ===
 +//BEST RELIABILITY//
 +
 +Easily the least desirable for EOPs. These systems have underwent serious motherboard changes, in a way that cripples hardware modding for all but the most devoted (ie. modchipping is very hard). One cannot even add more RAM. Continuing on, the XCalibur encoder in these systems cannot handle 480p output without difficulty; oddly though, they do RGB (not YPbPr) better than earlier revisions… without >480i res. Anyway, “b” revisions also use a low quality type of RAM. However, this revision is quiet and reliable, and it doesn’t have the notorious leaky clock capacitors; it’s worth considering for a non-EOP user. Since those bad caps were swapped, don’t replace them for now. To identify: Manuf. 03/14/2004 - 09/06/2004; 09/13/2004 - ? (1.6b). Serial 2nd half starts with 41, 43 for 1.6b. Kernel version: 5838. Shielding visible on bottom of AV port.
