PostSubject: XBOX hardware information   Sun Aug 19, 2007 2:13 pm

Xbox was the first console to incorporate a hard disk drive, used primarily for storing game saves compressed in ZIP archives and content downloaded from Xbox Live. This eliminated the need for separate memory cards (although some older consoles, such as the TurboCD, Sega CD and Sega Saturn had featured built-in battery backup memory prior to this). Most of the games also use the hard drive as a disk cache, for faster game loading times. Some games support "Custom soundtracks," another particularly unusual feature allowed by the hard drive. An Xbox owner can rip music from standard audio CDs to the hard drive so players can play their custom soundtrack, in addition to the original soundtrack of Xbox games that support such a feature.

Although the Xbox is based on commodity PC hardware and runs a stripped-down version of the Windows 2000 kernel using APIs based largely on DirectX 8.1, it incorporates changes optimized for gaming uses as well as restrictions designed to prevent uses not approved by Microsoft. A similar approach (PC hardware, stripped-down Windows) was used by the Tandy VIS entertainment system. The Xbox does not use Windows CE due to Microsoft internal politics at the time, as well as limited support in Windows CE for DirectX.[citation needed]

The Xbox itself is much, much larger and heavier than its contemporaries. This is largely due to a bulky tray-loading DVD-ROM drive and the standard-size 3.5 inch hard drive. Because of this, the Xbox has found itself a target of mild derision, as gamers poke fun at it for things like a warning in the Xbox manual that a falling Xbox "could cause serious injury" to a small child or pet. However, the Xbox has also pioneered safety features, such as breakaway cables for the controllers to prevent the console from being yanked from the shelf.

The original game controller design, which was particularly large, was similarly often criticized since it was ill-suited to those with small hands and caused cramping in the hands of some users. In response to these criticisms, a smaller controller was introduced for the Japanese Xbox launch. This Japanese controller (which was briefly imported by even mainstream video game store chains, such as GameStop) was subsequently released in other markets as the "Xbox Controller S", and currently all Xbox consoles come with a "Controller S", while the original controller (known as Controller "0", "The Duke", or "The Hamburger") was quietly discontinued.

Several internal hardware revisions have been made in an ongoing battle to discourage modding (hackers continually updated modchip designs in attempt to defeat them), cut manufacturing costs, and to provide a more reliable DVD-ROM drive (some of the early units' drives gave Disc Reading Errors due to the unreliability of the Thomson DVD-ROM drives that were used). Later generation of Xbox units that used the Thomson TGM-600 DVD-ROM drives and the Philips VAD6011 DVD-ROM drives were still vulnerable to failure that rendered the consoles either unable to read newer discs or caused them to halt the console with an error code usually indicating a PIO/DMA identification failure, respectively. These units would not be covered under the extended warranty.

Audio/video connectors
Standard AV Cable: Provides composite video and monaural or stereo audio to TVs equipped with RCA inputs. Comes with the system. European systems come with a RCA jack to SCART converter block in addition to the cable.
RF Adapter: Provides a combined audio and video signal on an RF connector.
Advanced AV Pack: Provides S-Video and TOSLINK audio in addition to the RCA composite video and stereo audio of the Standard AV Cable.
High Definition AV Pack: Intended for HDTVs, it provides a YPrPb component video signal over three RCA connectors. Also provides analog RCA and digital TOSLINK audio outputs.
Advanced SCART Cable: The European equivalent to the Advanced AV Pack, providing a full RGB video SCART connection in place of S-Video, RCA composite and stereo audio connections (composite video and stereo are still provided by the cable, through the SCART connector, in addition to the RGB signal), while retaining the TOSLINK audio connector. As Europe had no HDTV standard when the Xbox was release, no High Definition cable was provided in those markets.
Numerous unofficial third-party cables and breakout boxes exist that provide combinations of outputs not found in these official video packages; however, with the exception of a few component-to-VGA converters and custom-built VGA boxes, the four official video packages represent all of the Xbox's possible outputs. This output selectivity is made possible by the Xbox's SCART-like AVIP port.


Networking
Ethernet (Xbox Live) Cable: A Cat 5 cable for connecting the Xbox to a broadband modem or router.
Xbox Wireless Adapter: a wireless bridge which converts data running through an Ethernet cable to a wireless (802.11b or 802.11g) signal to connect to a wireless LAN. While the official Wireless Adapter guarantees compatibility with the Xbox, almost any wireless bridge can be used.
Xbox Live Starter Kit: A subscription and installation pack for the Xbox Live service, as well as a headset (with monaural earpiece and microphone) that connects to a control box that plugs into the top expansion slot of a controller. The headset can in fact be replaced with most standard earpiece-and-microphone headsets; headset specialist Plantronics produces various officially-licensed headsets, including a special-edition headset for Halo 2.
System Link Cable: A Cat 5 Ethernet crossover cable for connecting together two consoles or a Cat 5 straight through cable used in conjunction with an Ethernet hub for connecting up to four consoles, for up to 16 total players. This functionality is similar to Sega's DirectLink for Sega Saturn.

Multimedia
Xbox Windows Media Center Extender: A software kit released by Microsoft which allows Xbox to act as a Windows Media Center Extender to stream content from a Windows XP Media Center Edition computer. It can also be used for DVD playback.
DVD Playback Kit: Required in order to play DVD movies, the kit includes an infrared remote control and receiver. DVD playback was not included as a standard feature of the Xbox due to licensing issues with the DVD format that would have added extra cost to the console's base price. By selling a DVD remote separately, Microsoft was able to bundle the cost of the DVD licensing fee with it. Although there is nothing to prevent the Xbox from acting as a Progressive scan DVD player, Microsoft chose not to enable this feature in the Xbox DVD kit in order to avoid royalty payments to the patent-holder of progressive scan DVD playback. The DVD Playback kit only plays DVDs from the local region. The DVD Playback kit will also allow the Xbox to play VCD movies. By default, the Xbox can only play Xbox games and audio CDs.
Xbox Music Mixer: A utility software bundled with a microphone that connects to an adapter that plugs into the top expansion slot of a controller. Provides a music player with 2D/3D visualizations as well as basic karaoke functions. It also allows users to upload pictures in JPEG format (to create slide shows) as well as audio in MP3 format and Microsoft's WMA (for karaoke or a game's Custom Soundtracks feature) from a Windows XP machine running the Xbox Music Mixer PC Tool.

Standard Xbox Controller: Originally the normal Xbox controller for all territories except Japan, this has since been quietly discontinued and replaced in Xbox packs by the Controller S. The Duke controller has been criticized for being relatively large and bulky compared to other video game controllers (it was awarded "Blunder of the Year" by Game Informer in 2001).[4] The black and white buttons are located above the A, B, X, and Y buttons, and the Back/Start buttons are located between and below the d-pad and right analog stick. Also, the standard face buttons (A, B, X, and Y) were oriented in an oblong parallelogram rather than a uniform diamond, which was very unusual compared to other standard controllers.
Controller S: A smaller, lighter Xbox controller. Once the standard Xbox controller in Japan (codenamed "Akebono"),[5] it was released in other territories by popular demand, and eventually replaced the standard controller in the retail pack for the Xbox console. The white and black buttons are located below the A, B, X, and Y buttons, and the Back/Start buttons are similarly placed below the left analog stick. This controller has received its share of criticism as well, especially with regards to placement of the black/white and back/start buttons.[6]
There are also third party controllers such as a Logitech 1.2 GHz wireless controller. This controller is approved by Microsoft. However, third-party, unlicensed wireless controllers exist as well.

An 8 MB removable solid state memory card can be plugged into the controllers, onto which game saves (zip archives in reality) can either be copied from the hard drive when in the Xbox Dashboard's memory manager or saved during a game. Note that some recent games (e.g., Ninja Gaiden and Dead or Alive Xtreme Beach Volleyball) do not support this accessory as a cheat prevention measure. This system has been defeated by the Xbox hacking community, who have developed tools to modify savegames to work in a different console, though some unique technical information concerning the recipient Xbox must be known. It is also possible to save an Xbox Live account on a memory unit, making it possible to share it with another Xbox owner, assuming both have access to Xbox Live.
