  75         <p>
  76         This tool will help you perform an upgrade of the PosBox's software.
  77         However the preferred method to upgrade the posbox is to flash the sd-card with
  78         the <a href='http://nightly.openerp.com/trunk/posbox/'>latest image</a>. The upgrade
  79         procedure is explained into to the <a href='/hw_proxy/static/doc/manual.pdf'>PosBox manual</a>
  80         </p>
  81         <p>
  82         To upgrade the posbox, click on the upgrade button. The upgrade will take a few minutes. <b>Do not reboot</b> the PosBox during the upgrade.
