Well getting into firmware menu is a good sign ☺
http://elinux.org/Minnowboard:MaxBios#Change_Boot_Order
You should be able to see “Boot Maintenance Manager”, with the 4th option being “Change Boot Order”, you should be able to “<EFI Internal Shell>” (hit enter, + it to the top, hit enter) and commit the changes back to get back to the shell, and get your install going.
If that doesn’t work, let me know here and we’ll see what is going on.

So I FOLLOWED the procedure to pass from 64 to 32. I think the system filled 2 lines of dots, when the screen goes black. I waited about a half hour but there was no sign of new action, so I tried to reboot. Now the board has not EUFI Shell. But it does have setup, where the third line says it is MNW2CRB1.86C.0071.R30.1408131324. I was wondering what coused this, and how I get the board on work again?.
Thanks

I think there's some value in being explicit or otherwise we'll actually
cause confusion. I.E. when you download the firmware and people see
32-bit vs. 64-bit firmware in the same place will they always flash the
right one? Part of the problem is there is no UI to these firmware
flashers, they are command line utilities.
