Note that a clean install will reflash your XO; everything you created on it will be deleted. See olpc-update for an update that keeps some changes.

Official and Candidate Builds

  For the general public
Power & Game buttons for B2 and older XOs. B3 and newer have "O" at the top and "✓" (check) at the right.
  1. Download the OS image and its signatures file to your local computer. These are compressed files, but DO NOT open them — in your browser click the right mouse button over the link and choose "Save Link/Target As...".
  2. Copy these files onto a clean (Full, not Quick!, formatted) USB storage device that has at least 500 MB of space. Your USB storage device should now contain two files named something like: en708-1.img and fs.zip.
  3. Unmount the USB storage device and disconnect it from your computer when it is safe to do so.
  4. Shut down your XO laptop. Connect the USB storage device to the XO Laptop and power up while holding all the four game keys. (this is VERY important!)
  5. Release the game keys when the XO asks you to. The XO will take a few minutes to rewrite its memory.
  6. Reboot.
  7. Check that you have the correct build:

Development Builds

  1. Get a developer key for your XO laptop.
  2. Download the OS image (e.g. Template:Official-img-link) and its CRC file (e.g. Template:Official-crc-link) to your local computer. DO NOT open them. Important: If your computer runs on MS Windows, point your cursor on the link, click the right mouse button and choose "Save Link Target As".
  3. Copy these files onto of a clean (Full (not Quick!) formatted) USB memory stick. Your USB memory stick should now contain two files named: for example, os708.img and os708.crc.
  4. Unmount the USB memory stick and disconnect it from your computer when it is safe to do so.
  5. Shut down your XO laptop. Insert the USB stick into the XO Laptop and power up while holding the escape key (the circled "x" in the upper left corner of the keyboard).
  6. Release the 'x' key when it asks you to. You should be at the OpenFirmware "ok" prompt.
  7. Assuming that your disk image is named _____.img, type
 probe-usb copy-nand disk:\____.img 
(e.g. os708.img, os2230.img, en708-1.img, ...)
8. Press Enter, then wait while your machine reflashes.
9. When the "ok" prompt returns, reboot the machine.
