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.

Download the OS image and its signatures file to your local computer. DO NOT open them. P.S. If your computer runs on MS Windows, point your cursor on the link, click the right mouse button and choose "Save Link Target As".
- Official OS images can be downloaded from http://download.laptop.org/xo-1/os/official/, http://download.laptop.org/xo-1/os/candidate/, and sometimes from http://download.laptop.org/xo-1/os/custom/.
Copy these files onto of a clean (Full (not Quick!) formatted) USB memory stick. Your USB memory stick should now contain two files named something like: en708-1.img and fs.zip.
Unmount the USB memory stick and disconnect it from your computer when it is safe to do so.
Shut down your XO laptop. Insert the USB stick into the XO Laptop and power up while holding the four game keys. (this is VERY important!)
Release game keys when it asks you to. It will take a few minutes to rewrite the memory.
Reboot.
Check that you have the correct build:
- Hover over the XO in the Home screen and click on 'About my XO'
- Check that the build number matches build number of the image file you downloaded, e.g. 'Update.1 708, firmware Q2D16' for en708-1.

For Developers

Get a developer key for your XO laptop.
Download the OS image and its CRC file to your local computer. DO NOT open them. P.S. If your computer runs on MS Windows, point your cursor on the link, click the right mouse button and choose "Save Link Target As".
- Development images can be found at [1] and from many other sources.
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.
Unmount the USB memory stick and disconnect it from your computer when it is safe to do so.
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).
Release the 'x' key when it asks you to. You should be at the OpenFirmware "ok" prompt.
Assuming that your disk image is named _____.img, type

 copy-nand u:\____.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.
