[MinnowBoard] android instalation problem on a new minnowboard max - problem switching to non-secure uefi mode in security prompt - volume up key is not available on the minnow max

[Gabi Voiculescu]

Greetings community.
I have recently purchased a pair of Minnowboard Max Dualcore boards. I aim to do both work and hobby low level development and studies on an Android Intel SoC.
I tried to install Android 5.0.1 using the android 5.0 bringup guide from 01.org [1], using as a host PC ubuntu 12.04 (for usb drive flashing).
Firmware is X64.0077 64bit. Following the guide that stated I do not need to replace the firmware (as it's newer than 0076), I proceeded to only download the installer [2] from [3].
I followed the steps in the guide [1], after I flashed a usb stick (16GB) with fastboot-usb.img.


Below are a few of the steps I did.   
   - On the Linux PC, from a terminal window, extract the archive and then change to the extracted directory using the following commands:   

    unzip  android-5.0.1_r1-ia1-minnowboard_max-64bit-userdebug.zip    cd  android-5.0.1_r1-ia1-minnowboard_max-64bit-userdebug   
   - Unmount any partitions that were automatically mounted, using the following command, where X is the letter identified above:   

     sudo umount /dev/sdb   
   - Write fastboot-usb.img to the USB thumb drive using the following command   

     sudo dd bs=1M if=fastboot-usb.img of=/dev/sdb conv=fsync   
   - I used a usb hub in the board's usb 2.0 port to give me extra ports for a usb mouse and keyboard. The usb stick with fastboot-usb went into the oard's usb 3.0 port. MicroHDMI connected to a monitor.   

   - I then powered the board
   
   - Pressed F2 while booting to enter the Device Manager.   

   - Select Boot Manager and press Enter.   

   - Select EFI USB Device and press Enter   



After I select EFI USB Device I get a security warning about disabling UEFi secure mode on my screen. 
<excerpt from my monitor>BOOTLOADER ERROR CODE 04STARTPress Volume UpPOWER OFFPress Volume DownWARNING: Your device has been altered from it's factory configuration and is no longer in a locked or verified state due to UEFI secure Boot being disabled. If you were not responsible for these changes the security of your device may be at risk. Enter BIOS to re-enable UEFI Secure Boot.</excerpt>


The guide from 01.org mentions this: Note: The device may show the security prompt because secure boot is disabled. You may need to press the Up Volume key to allow the boot to continue.

I don't have a volume up key on my board, to press. Board SW1 acts like a reset.
I don't have a lure either, to have additional push buttons.

How can I proceed with the install / run of Android on the MinnowBoard MAX?
Best regards,Gabi
