    Please how would I boot from it as it won't show on the graphical menu?
    I am very new to this PowerPC/Openfirmware stuff, despite having about 80 computers from the 80's.

    OK, first you need to download the 'hybrid' hdimage from MorphOS website. The one described as "SD Card / USB Image for Efika, Sam460, X5000".
    Then you need to find a USB pendrive of low capacity (the best would be 2 or 4 GB, although I used a 8 GB one and it worked).
    Then you need to save the hdimage to it. You can use the Raspberry Pi Imager for Windows. You need to select "other image" and force using the 'hybrid' hdimage you've downloaded earlier.
    Then, the last thing you need to do is change the boot device in Open Firmware. To do this you use the command:

    Code:
    setenv boot-device ud:,\:tbxi


    From this point on, when there's the (earlier prepared) pendrive plugged in - your system will boot from it.


    Thanks for your reply.

    I've been using Balena Echer in both MacOS and Windows to create this kind of USB pendrives.
    But Raspberry Imager is a nice catch. Will do!

    This command will set the boot device in nvram do be the ud (USB Device), right?
    This PowerMac never answered commands listed to the ud device, probably due to this?
