The MinnowBoard MAX uses a UEFI system level firmware, and provides both the UEFI shell, and a typical BIOS style menu interface.

UEFI Shell

UEFI Shell prompt

The simplest way to get to the UEFI shell is to:

  1. Make sure that the MinnowBoard MAX is powered down
  2. Disconnect all bootable media
    1. USB drives
    2. SATA drives
    3. SD cards
  3. Power on the MinnowBoard MAX

At this point you should get a screen that looks very similar to the one at right. This is the UEFI Shell, there are a number of commands that can be done here, and the system can be explored in great depth from this interface.

Places to find more information about UEFI shell and it's commands:

BIOS menu

Exit UEFI Shell prompt

The BIOS menu gives a more traditional way to configure the basic firmware parameters on the system, set the GPIO pinmux states and perform the typical tasks one would expect to do in these menus.

To get to it:

  1. Key-press way
    1. Press F2 during bootup to jump directly to it
  2. UEFI Shell way
    1. Follow the steps to get to the UEFI Shell (above)
    2. Type the following:

You should now get a screen that looks like the following: Main BIOS menu screen

This is the main menu on the BIOS menu

BIOS Menu Tree


This just continues the boot process

Select Language

This adjusts the language that the bios is displayed in

Boot Manager

This adjusts the basic boot options, including what to boot to.

EFI Internal Shell

This will boot to the UEFI shell

Device Manager

This allows for the configuration of specific devices on the system
