AmigaOne - U-Boot Prefs Menus - Boot Sequence


Editing Boot Sequence

The fourth parameter "Boot Sequence" is used to specify the boot method, the U-Boot Menudelay value, the boot arguments that you want to boot AmigaOS or Linux with, the Network boot options, device sequence for Amiga Multiboot and the Linux boot options.

U-Boot Preferences Menu with Boot Sequence highlighted

If you press <Enter> a new window showing all of the boot options and arguments will appear. Highlighting an appropriate value and pressing <Enter> will result in one of the following screens:

Editing Boot Method
Pressing <Enter> while the Boot Method value is highlighted will display the following options:

U-Boot Preferences Boot Sequence Boot Method

Use the up/down arrow keys to highlight the appropriate value and press <Enter> to select it. Assuming that you are running AmigaOS (and why wouldn't you?) the normal value is that shown highlighted above. However, if you are not running AmigaOS but only using Linux, then the normal value would be "Linux Boot".

Editing Initial Boot Delay
Pressing <Enter> while the Initial Boot Delay value is highlighted will display the following options:

U-Boot Preferences Boot Sequence Boot Delay

Use the up/down arrow keys to highlight the appropriate value and press <Enter> to select it. The normal value is that shown highlighted above.

Editing Boot Arguments for AmigaOS
Pressing <Enter> while the Boot arguments for AmigaOS value is highlighted will display the following:

Editing Boot Arguments for Linux
Pressing <Enter> while the Boot arguments for Linux value is highlighted will display the following:

U-Boot Preferences Boot Sequence Boot Arguments for Linux

Simply edit the text string as necessary and press <Enter> to accept it. A typical value for a Linux only system is shown above, whereas a multi-boot system would be more likely to have hda3 or hda4. However, this value is only required where Linux is run stand-alone without AmigaOS. On a dual-boot system the arguments for Linux are read from the "/boot/a1boot.conf" file instead.
