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. |
|||
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. |
|||
* 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]]. |
|||
You can download the latest images from: |
|||
* 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?]]. |
|||
[http://olpc.download.redhat.com/olpc/streams/development http://olpc.download.redhat.com/olpc/streams/development] |
|||
* 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 |
|||
=== Latest Stable Build === |
|||
* To build your own image, see [[Building custom images]]. |
|||
A build is marked "stable" when the developers are happy with a build. At minimum, a stable build will meet the criterion: |
|||
* USB image on A test board with Insyde BIOS |
|||
* NAND image on A test board with Insyde BIOS, booting via USB and kexec'ing into a kernel loaded from NAND (select OLPC NAND in grub on the USB stick) |
|||
* QEMU image |
|||
* USB image for A test board with LinuxBIOS (for post-build59) |
|||
At some point this will include: |
|||
* NAND flash image for A test board with LinuxBIOS |
|||

|||
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. Casual downloader and those upgrading to a new build beware: check the mailing list to see whether there are known problems before selecting a build. |

The latest stable build is [http://olpc.download.redhat.com/olpc/streams/development/build59-20060808_1153/ build59]. --[[User:Blizzard|Blizzard]] 23:35, 8 Aug 2006 (EDT) |

== Image variants == |
|||
Images are available in two variants |
|||
* Normal images, in <tt>images/</tt> sub-directory |
|||
** Intended for production use |
|||
** Does not contain tools or software suitable for developers of the OLPC operating system |
|||
* Developer images, in <tt>images-rpm/</tt> sub-directory |
|||
** 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 |
|||
** '''WARNING''': Do not attempt to update the kernel on <tt>images-rpm</tt> builds - the <tt>initrd</tt> will be wrong. We're working on fixing this through including an <tt>olpc-mkinitrd</tt> package. |
|||
Each variant may have available in three sub-variants: |
|||
* ext3: ext3 filesystem; use this if you don't know what you need |
|||
* jffs2: JFFS2 filesystem that will be used on the NAND flash on OLPC hardware |
|||
* tree: Have no filesystem, and consist of just a tarball of the OS directory tree |
|||
=== Passwords === |
|||
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.'' |
|||
== Using Images == |
|||
For development we right now offer images that runs the OLPC operating system off a USB storage device. We're working on getting this to work on the NAND flash of the hardware too. Instructions to come. |
|||
=== Images on a USB disk === |
|||
The [[OS images for USB disks]] page describes how to write these images to a USB disk, so that you can test the images on real OLPC hardware, or attempt to boot from them on your own PC. |
|||
=== Images on an emulator === |
|||
The [[OS images for emulation]] page details how you can run the OS images on a normal PC, without the OLPC hardware. |
|||
=== Images with the on-board NAND flash on OLPC hardware === |
|||
Instructions coming soon... |

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.
