Note that there are two SATA-like connectors on the Novena +mainboard: one is for power from the battery board, and the other is the actual +SATA connection. It isn't possible to connect to the wrong port because the +polarities are flipped. + +First make sure required tools are installed:: + + sudo apt-get install parted debootstrap + +We're going to assume that the SATA disk is blank and unpartitioned, and **all +data on the disk will be overwritten**. + +We're going to use the offical ``novena-image.sh`` install script. Checkout out +xobs' novena-image repo:: + + sudo apt-get install apt-cacher-ng + cd + git clone https://github.com/xobs/novena-image + +You'll almost certainly want to install apt-cacher-ng and change the mirror +setting (in sata-install.sh) to '--mirror +"http://127.0.0.1:3142/http.debian.net/debian"' (the default is a debian mirror +in Hong Kong). We recommend copying ``sata-install.sh`` to ``local-install.sh`` +and making changes there. See the `novena-image.sh documentation +<http://kosagi.com/w/index.php?title=Novena_Image_script>`_ for more details on +how to, eg, auto-populate the kosagi signing key into the new image. + +If you are running from the microSD card and have limited space, you'll +probably want to cull down the default installed package list significantly. + +When ``local-install.sh`` looks good, run the script:: + + # WARNING: VERY DANGEROUS COMMAND! + sudo ./local-install.sh /dev/sda + +To actually boot from SATA we need to set a flag in EEPROM. Run +``novena-eeprom`` and take note of the Features list, then add ``sataroot`` to +the list and write it:: + + # Edit this list for your board + novena-eeprom -f es8328,pcie,gbit,hdmi,eepromoops,sataroot -w + +The ``novena-image.sh`` script should have taken care of setting the SATA +disk's ID correct, so you're ready to reboot! + +After booting into this fresh system, you might want to loop back to the +:doc:`quickstart-board` page. A few errata and things that might pop up: + +- need to fix /etc/apt/sources.list to remove localhost prefix (from + apt-cacher-ng) +- run ``apt-get install -f`` to fix any outstanding apt issues +- need to add ``deb http://repo.novena.io/repo/ jessie main`` to get kosagi + updates +- if they aren't already installed, run ``apt-get install novena-eeprom + kosagi-repo novena-disable-ssp novena-usb-hub`` (etc) +- need to create a user (``adduser``, then ``usermod -G`` to add to sudo group) +- need to install a fuller set of packages if only a subset were installed to + save disk space earlier Flashing Factory Image to microSD Card ------------------------------------------- |
