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

UEFI Shell
The simplest way to get to the UEFI shell is to:
- Make sure that the MinnowBoard MAX is powered down
- Disconnect all bootable media
- USB drives
- SATA drives
- SD cards
- 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:

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:
- Follow the steps to get to the UEFI Shell (above)
- Type the following:
exit
You should now get a screen that looks like the following:
This is the main menu on the BIOS menu
