Dear charlène, Thank you for your quick reply, really appreciated :)
I'm sorry but I fail to see the additional steps required to make this work: 0 > dev / ls ff9b1200: /usb@1b, 1 ff9e3c20: /disk@1 0 > devalias ud /pci@f2000000/usb@1b, 1/disk@1 0 > boot ud/disk@1:2,ofwboot /6.9/macppc/bsd.rd can't OPEN: ud/disk@1:2,ofwboot Can't open device or file ok 0> Could the root issue come instead from the USB drive ?
