===== Booting from USB  =====

On some machines (which?) USB devices simply show up in the boot picker. If not...

==== OF v4.9 / 5.2 and newer ====
<code>boot ud:,\\:tbxi</code>

==== Older OF ====

Determine USB device path with ''dev / ls'' and ''devalias''

Look for something like this:

<code>/pci@f2000000/usb@1b,1/hub@1/disk@1</code>

Then boot with:

<code>boot usb0/disk:2,\\:tbxi</code>
