[MinnowBoard] 64-bit vs 32-bit UEFI - What you need to know!

[Ferchu R]

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
