<p dir="ltr">As a workaround, You can get to the EFI shell using a FTDI cable.</p>
<p dir="ltr">That should allow you to do the efi firmware update, but you still wont have access to the bios screen.</p>

<p class="MsoNormal">I have the same problem like <a href="http://minnowboard.57273.x6.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=55" target="_blank"><b><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#551a8b;background:#eeeeee">Bryan

when i am booting my minnowboard i cant see anything until the linux mint logo appears. So it is not possible to boot in the UEFI and boot/install another linux distribution.<u></u><u></u></p>

that this is a firmware / HDMI Issue with some displays. I have the minnowboard from the last batch send out 11/11/14 by mouser. I did a firmware updated and installed linux mint 17.<u></u><u></u></p>

<p class="MsoNormal">Is the board or uefi broken? Is there a workaround for updating or fixing that issue "blind"? Is there a way to boot a different linux distribution from a usb stick from a comand in the installed linus?<u></u><u></u></p>
