[MinnowBoard] BIOS/UEFI/Firmware settings hotkey?

Dave,

You are incorrect. There is still support for graphical setup browsers in
UEFI. Any modern UEFI-based PC motherboard is a great example of this. In
fact, most native UEFI browsers are much nicer than legacy bios
implementations.  (Decent graphics and mouse support.)

I'm looking through the source tree now, and have identified that Intel has
left code for boot device management and configuration in the tree- see the
comment below from /IntelFrameworkModulePkg/Universal/BdsDxe/FrontPage.c


    //
    // If gCallbackKey is greater than 1 and less or equal to 5,
    // it will launch configuration utilities.
    // 2 = set language
    // 3 = boot manager
    // 4 = device manager
    // 5 = boot maintenance manager
    //

I do not have a minnowboard to test on, and they may have neutered it
somewhere, but am looking for the hotkeys currently.

Thanks,
Neill
