Ubuntu core NUC instructions wrong

[Greg Lueck]

This bug report is against the following web page:

https://developer.ubuntu.com/core/get-started/intel-nuc

The instructions on that page should state that a BIOS setting must be changed to enable the eMMC storage (which is not the default). If you don't do this, the commands listed on that page fail in a non-obvious way.

For example, you could add the following text after the bullet item that reads "The NUC needs to have its BIOS updated to the latest version. For this, you can follow online instructions on the Intel website":

  * The BIOS must also be configured to enable the eMMC storage. To do this:
    1. Press F2 during boot to enter Intel® Visual BIOS.
    2. Go to Boot > Boot Configuration.
    3. Set OS Selection to Linux. This option automatically enables the eMMC device.
    4. Press F10 to save and exit.

The instructions I suggest above come from this web site: http://www.intel.com/content/www/us/en/support/boards-and-kits/000006602.html
