===== Download Image file =====

The most recent images can be downloaded from the OpenVario-FTP-Server:

If you are confused by the big number of files, check out the available [[projects:series_00:variants]]


===== Unpack Image =====

For faster download the image file is packed using **tar** and **gzip**.
Before the image can be written to a SD-Card, it has to be unzipped. This can be done with 

  * [[http://www.7-zip.org/|7zip]] in Windows OS
  * **tar** in Linux OS  



===== Write an Image to an SD-Card =====

To create a SD-Card for booting your FlightComputer the following requirements have to be fullfilled:

  - Downloaded Image file
  - microSD-Card (at least 4GByte)

==== Using Windows ====

If you are using a Microsoft Windows Operating System a tool to write the image to an SD-Card is needed:

[[http://sourceforge.net/projects/win32diskimager/|Win32DiskImager]]

  - Install the tool mentioned above
  - Start the tool
  - Select the "Image file" downloaded before
  - Select "Device" the image should be written to
  - Press "Write" the write the image to the selected device

** Pay attention: The selected device will be erased completely !!! **

==== Using Linux ====

If Linux is used for writing the image to a SD-Card no additional tool is need.
The necessary tool is included in almost every Linux distribution.

<code>
dd if=<image file> of=/dev/<device>
</code>

Replace <image file> with the name of the downloaded image and <device> with the device your SD-Card is mapped to.
