====Install====
  * Run the ''flashall.sh'' script.<code>sudo ./flashall.sh</code>
  * Reconnect power (bottom cable on photo above).
  * Monitor the installation (using serial console on another window), it involves three reboots, so don't pull the cords yet.

====Configure====
  * Change ''edison'' and ''root'' passwords, default password is ''edison''.
  * Edit ''/etc/rc.local'' For example: <code>
### uncomment to disable USB device mode and enable host mode for the OTG port
rmmod g_multi || true
</code>
  * Configure WPA_supplicant:<code># wpa_passphrase SSID      # add output to /etc/wpa_supplicant/wpa_supplicant.conf

# vi /etc/network/interfaces
auto wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

# ifup wlan0</code>
  * If WiFi lags, disabled powermanagement (for example in /etc/rc.local):<code>iwconfig wlan0 power off</code>
  * Update:<code>apt-get update
apt-get upgrade</code>
  * Configure powerbutton handling. See: http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-edison/plain/meta-intel-edison-bsp/recipes-support/pwr-button-handler/files/<code>
