  2. Copy these files onto of a clean (Full, not Quick!, formatted) USB flash drive. Your USB flash drive should now contain two files named something like: en708-1.img and fs.zip.
  3. Unmount the USB flash drive and disconnect it from your computer when it is safe to do so.
  4. Shut down your XO laptop. Insert the USB flash drive into the XO Laptop and power up while holding the four game keys. (this is VERY important!)

  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.
