Components of a path are in this general form: <name>@<address>:<arguments>
Name can be safely omitted as the device is actually getting located by its address. Therefore, these two paths refer to the same device: /pci@f4000000/ata-6@d/disk@0:b /@f4000000/@d/@0:b Find freely available references on openfirmware matters at: http://firmworks.com/ https://www.openfirmware.org/Welcome_to_OpenBIOS
