Thank you, the early startup was the option I'd read something about but couldn't remember precisely what it was. The odd things are using either this, or Set Echo on,
1) using the Set Echo on option, after the Amiga has finished booting once it will boot after every soft reset, even if I've removed the line from the SS
2) using the trace startup option the startup Gurus after the second bootup reset (after Loadmodule) before it even displays any choices for me as if it doesnt get as far as the SS. Similarly to 1, if I successfully boot, then remove the Set Echo On line, soft reset and use the Trace option in a subsequent reboot, it all loads without issue.
