[MinnowBoard] BIOS/UEFI/Firmware settings hotkey?

Correct
I did try hitting + and - a bunch while booting but all I ended up
with is + and - on the shell prompt.
Also it appears I can get to that menu by doing exit two consecutive
times from the shell (it's therefore possible that the menu existed
pre-1.0 and that I just never bothered to exit twice in a row.) The
reason I'm still searching for the magic key to break into a boot menu
is because even hitting esc a bunch won't drop me to the EFI shell
when booting Windows 8. There you have to either do the special
settings dance from within windows (which I've seen before but haven't
re-looked up), or you take the simpler route of just unplugging the HD
and waiting for the shell/boot menu.
I'm done for the day but tomorrow I will try messing with bcfg to see
if I can disable the fastboot to make it maybe just stall at the boot
menu so that I always have to press enter (or hopefully it would
timeout after 5 sec) to then boot into the first entry. (The yocto
document is interesting because it says "Select the Shell from the EFI
boot menu, or allow it to timeout and start the shell automatically."
which implies I should be seeing the boot menu before it goes into the
shell which is definitely not the case. I see "Connecting all devices"
and then straight to shell (or win 8 boot) no matter what keys I
hammer on.)
