-If you don't have the ''ud'' alias, you'll have to search usb* aliases for a correct path in the OF tree. List the aliases again or just start trying to list usb0, usb1, etc., devices until you find a device containing '''disk''' in its name, and that will reveal the full path to the USB stick, which can be used instead of the ''ud'' alias.

 === Boot Arguments ===
-Several boot arguments can be given to the ''boot.img'' file by adding them to the end of a ''load'' or ''boot'' line. More detailed explanations of these arguments can be found from '''Docs/Booting MorphOS.txt''' and '''Docs/PegasosFirmware.txt''' files on your MorphOS system or the installation CD, but let's cover the most useful booting related ones here.
+Several boot arguments can be given to the ''boot.img'' file by adding them to the end of a ''load'' or ''boot'' line. More detailed explanations of these arguments can be found from '''Docs/Booting MorphOS.txt''' and '''Docs/PegasosFirmware.txt''' files on your MorphOS system or the installation CD, but let's cover the most useful booting related ones here. Note that Sam460ex/cr and AmigaOne X5000 systems don't use Open Firmware, but the boot arguments can be given on them too by setting an environment variable in their [[Tips_and_Tricks#MorphOS_Boot_Arguments_on_U-boot_Systems | U-boot console]].
 Without arguments MorphOS boots a device that is bootable and has the highest boot priority set. '''Note''' that this only applies to partitions that contain a MorphOS compatible bootable [[Filesystems|filesystem]]. If a MorphOS installation CD is inserted, it usually has a higher priority than bootable partitions on the HD. The HDConfig tool can be used to set partitions bootable and alter their boot priorities, but usually it's unnecessary to change these settings.
