OLPC produces OS images (also known as software builds) which can be installed on XO laptops, customized and rebuilt by deployments, etc. These images include all of the system and user software, allowing your XO to boot straight into OLPC's software environment.

To install a specific build on your laptop, follow the links to one of the XO releases from the box on the right. For other releases, see Releases.
The Release notes for each release have instructions for installing or upgrading to a release on your XO. The Updating the XO page references other ways that software images can be installed.
If you want to identify which build/release is running on your XO, see What release am I running?.
If you are interested in testing upcoming releases, the Friends in testing page explains where you can start.
If you know what you're doing, you might be able to find the files that you're looking for on http://download.laptop.org
To build your own image, see Building custom images.

+OLPC produces '''OS images''' (also known as '''software builds''') which can be installed on XO laptops, customized and rebuilt by deployments, etc. These images include all of the system and user software, allowing your XO to boot straight into OLPC's software environment.
-== Definition ==
+* To install a specific build on your laptop, follow the links to one of the XO releases from the box on the right. For other releases, see [[Releases]].
-OLPC and Red Hat continually develop the Fedora-derived OLPC Linux operating system. Each day, we freeze the most up-to-date version of that OS, and make it available for download as an OS image.
+* The [[Release notes]] for each release have instructions for installing or upgrading to a release on your XO. The [[Updating the XO]] page references other ways that software images can be installed.
+* If you want to identify which build/release is running on your XO, see [[What release am I running?]].
-=== Upgrades ===
+* If you are interested in testing upcoming releases, the [[Friends in testing]] page explains where you can start.
+* If you know what you're doing, you might be able to find the files that you're looking for on http://download.laptop.org
-XO users should follow [[olpc-upgrade]] or [[Secure upgrade]] to upgrade to later system software.
+* To build your own image, see [[Building custom images]].
-For developers, another recommended method to update your development board or BTest system, is [[Autoreinstallation image]].  Please see that and then return here if you want a different image.
-=== Downloads ===
-As the operating system for OLPC is under development, there are several builds available. The latest build might not always be stable since developers are experimenting with new features.  Each build is labeled with a unique version number.  When reporting problems on mailing lists, please make sure you list the build number you are using.
-Stable, signed builds for the XO-1 are available from:
-* http://download.laptop.org/xo-1/os/official/
-Signed, release candidate builds are available from:
-: http://download.laptop.org/xo-1/os/candidate/
-"Update.1" images include relatively stable builds leading up to the next 8.1.''x'' build. (As of August 2008, build 711 is the latest candidate for a possible 8.1.2 release in the update.1 build stream):
-: http://pilgrim.laptop.org/~pilgrim/olpc/streams/update.1/
-You can download unstable development images from:
-: http://xs-dev.laptop.org/~cscott/olpc/streams (look in "latest" in each stream's directory) &mdash; [[joyride]] is the primary stream, other streams such as "faster" may be available for testing experimental features
-And historical builds are available from:
-: http://olpc.download.redhat.com/olpc/streams/development
-=== Latest stable build ===
-A build is marked "stable" when the developers are happy with it. At minimum, it should boot successfully on A-Test boards and B-Test laptops.  A stable build does not mean everything is working, nor that it is actually "stable." For example, for a while [[Sugar]] and X were both broken in a stable build, but virtual consoles worked fine and that was enough to get work done for most developers.
-The latest stable build is the highest-numbered build at http://download.laptop.org/xo-1/os/official; the green "infobox" on this page and others also gives the latest stable.
-=== Release candidate ===
-When developers have some confidence in a particular build, they may invite wider testing of it;
-see [[Friends in testing]].
-Some release candidates are signed and thus can be installed on any XO; others are unsigned and require that you get a [[developer key]].
-=== Development builds ===
-Casual downloaders and those upgrading to a new build '''beware''':
-* check the [http://dev.laptop.org/tinderbox/ Tinderbox] to see whether there are known problems before selecting a build
-* read the [[Test Group Release Notes]] to look for testing results on a build
-* you must get a [[Developer key]] before you can install a development build on your XO
-== Image variants ==
-Images are available in five variants
-* Normal images in the <tt>ext3/</tt> and <tt>jffs2/</tt> sub-directories
-** Intended for production use
-** Does not contain tools or software suitable for developers of the OLPC operating system
-** The <tt>ext3/</tt> images are intended for USB drives (both hard drives and flash drives)
-** The <tt>jffs2/</tt> images are intended for the on-board NAND flash.
-* Developer images in the <tt>devel_ext3/</tt> and <tt>devel_jffs2/</tt> sub-directories
-** Contains tools useful for developers of the OLPC operating system, including: <tt>yum, rpm, vim-minimal, openssh-server, xterm, which, file, tree, wget, xorg-x11-twm, gdb</tt> packages
-** The <tt>devel_ext3/</tt> images are intended for USB drives (both hard drives and flash drives)
-** The <tt>devel_jffs2/</tt> images are intended for the on-board NAND flash
-** '''WARNING''': Do not attempt to update the kernel on <tt>devel_*</tt> builds - the <tt>initrd</tt> will be wrong. We're working on fixing this through including an <tt>olpc-mkinitrd</tt> package.
-* Live CD images in the <tt>livecd/</tt> sub-directory
-** Contains an iso of a normal image which can be burned onto a cd and run by booting off the cd drive
-Each variant may have available two sub-variants:
-* tree: a tarball of the OS directory tree, without a filesystem
-* img: a filesystem image (of one of the types described above).
-== Languages in which the images are available ==
-* English
-* The [[Localization|home Language]] for each participating country
-== Using Images ==
-For development we offer images that run the OLPC operating system off a USB storage device.  These images are located in the <tt>devel_ext3/</tt> sub-directory, and should be used if you're unsure of which image to choose.
-=== Passwords ===
-Some recent builds do not permit root login.  There are quite a few tickets.  You can login as ''olpc'', no password, and <tt>sudo -i</tt> instead. [[User:MitchellNCharity|MitchellNCharity]] 14:40, 6 January 2008 (EST)
-The images have no password set at build time. This means you can log in as root using no password. Always remember to change the password as the first thing when start using an image.
-As the <tt>image-rpm</tt> variant ships with an SSH server you thus need to set the password to be able to login from a remote host. This is a feature of <tt>sshd</tt>.
-''Password handling is subject to change before official release.''
-=== Images on a USB drive ===
-The '''[[OS images for USB disks]]''' page describes how to write these images to a USB disk or flash drive, so that you can test the images on real OLPC hardware, or attempt to boot from them on your own PC.
-=== Updating from USB ===
-Newer build directories also provide <tt>os''NNN''.toc</tt> and <tt>os''NNN''.usb</tt> files.
-These are reference files for the [[olpc-update]] command-line tool, so that you can update a running XO to the new build from a USB flash drive.
-=== Images on an emulator ===
-The '''[[Emulating the XO]]''' page details how you can run an image of the OLPC operating system on a normal computer that doesn't have the OLPC hardware.
-=== Images with the on-board NAND flash on OLPC hardware ===
-See the [[Clean-install procedure]] and the [[Olpc-update]] page.
-=== Wireless ===
-See the [[Wireless]] page for detailed instructions.
-== Test Group Release Notes for Images ==
-The [[Test Group Release Notes]] page lists the "official" changelog and known problems for each build.  Check that page to see if there are any known problems with the build you're installing.
-== User Feedback on Images ==
-Using the [[User Feedback on Images]] page, you can see how the images worked on various systems, using various different hardware and emulator set-ups.  You can also add your own reviews.
-== Build names and branches ==
-(Moved to separated [[Builds]] page; also see [[Releases]].)
-== Building your own custom images ==
-See [[Building custom images]]
