[MinnowBoard] BIOS/UEFI/Firmware settings hotkey?

Hi  Jack,

Pls use the "bcfg" shell command to change the boot order - that command modifies the UEFI NVRAM entries which should allow you to change the boot entries or driver options.

Quick tutorial:

At the UEFI Shell prompt, enter the following shell command to display current boot entries:

bcfg boot dump -v

In my MB, it shows the following boot options:

Option: 00. Variable: Boot0000
  Desc    - Shell
  DevPath - Fv(07F426A2-5F6B-4ED5-9B35-6FF191BFB4DD)/Shell
  Optional- N
Option: 01. Variable: Boot0001
  Desc    - UiApp
  DevPath - Fv(30D9ED01-38D2-418A-90D5-C561750BF80F)/UiApp
  Optional- N
Option: 02. Variable: Boot0002
  Desc    - EFI USB Device
  DevPath - PciRoot(0x0)/Pci(0x17,0x0)/Pci(0x0,0x0)/Pci(0x8,0x3)/USB(0x0,0x0)/HD(1,MBR,0x00000000,0x40,0x3BAFC0)
  Optional- N

Now, to change the boot order and have the "UiApp" as first option, simply move it to the top.  I used the following command to do so:

bcfg boot mv 1 0

Pls let me know if you have any questions.

Thanks,
Elmer

Thanks Neill.

And Dave you're extra incorrect (I don't know why someone from the company that's making minnows would argue that any UI is evidence of legacy BIOS :/). After I updated the minnow to firmware 1.0 and unplugged my HD (or if I do some sort of weird combo of typing exit then hitting esc then typing exit from the shell) I now have a boot menu option which lists "shell", or "UiApp" which takes me into the expected settings UI (and it even has options for enrolling keys for secureboot and such!), or my bootable HD, bootable USB, or boot from network (IPv4 and IPv6).

So my question kind of still remains: is there anything I can mash to guarantee I get directly to that menu without having to go through the shell exit/esc rigamarole?


Much appreciated,
JB
