Yep that's it, since you do not need HEXPAX to do this, you can configure your NoV-64d module as a Clonix-D and copy the ROM's in it.

Q5: You can use the RAMBox32 as a standard MLDL box and when used that way you do not need the RAMBox OS at all.

Q7: Nop! what you have listed is what I have.

Most of what I know comes from these documents, trial and error testing several setup, hanging my units several times until I understood them completely.
Jürgen initialization module was invaluable for restoring my hanged units while testing.

Great, that's all good news, thanks for confirming these points.

I mentioned ZenROM and HEPAX as they both have utility functions for copying ROM. I believe I'll have to use some different ROM for this, even though the RAMBox contains the COPYPG function, as the RAMBox ROM image will be replaced, so that function can't be run from here (right?).

I'll email you the exact proposed procedure just to double-check, as I don't want to kill my RAMBox completely and would like a nod to confirm it; as it is now, it's still mostly functional. I doubt the details of the process interest anyone else here.
