AmigaOne - U-Boot - Boot Select Menus


The U-Boot Menu system is easier to use than the console mode. It allows you to define settings, display information about your system, which disk you want to boot from, etc.

U-Boot Menu Usage
The following usage information applies to all U-Boot Boot Menus.

  • The parameter to be modified (or selected) is highlighted by a green bar.
  • To move to the value you want to modify (or select), use the up/down arrow keys.
  • Press <Enter> to change (or select) it. In case of a changeable setting, you'll then be able to select a different value in a drop down menu, or to enter some text to modify a text based setting.
  • Everywhere in the menus, <Enter> is to select/modify and <Esc> is used to quit/cancel.
U-Boot Boot Selection Menu
The boot selection menu can be used to temporarily change the boot device, boot configuration and boot arguments that you want to boot AmigaOS or Linux with, and is invoked by pressing <Enter> while the U-Boot Menudelay panel is in countdown mode. If you want to make permanent changes you should press <Esc> and go to the U-Boot Preferences Menu instead.
