: That’s not the rom I had in mind but yes, that’s the command concept I was referring to. There’s definitely then at least one more rom out there that supports a similar command but maybe it’s a bit excessive to take up a rom slot just for that command? It would certainly solve your problem more elegantly though in that you could force the format command straight through to the Peg DFS.
However, after some more thought…..
Since you’ve got to type *KILL twice and then re-cycle, it might be easier if you were to temporarily disable the PRES Expansion rom with a suitable poke to the ROM Byte Table which, in the Elk, is at $2A1 to $2B0 where the byte for rom id 0 is at $2A1 and the byte for rom id 15 is at $2B0.
For example, if your PRES Expansion rom is in say slot 5, its type byte is at location $2A6. Thus, each time you want to format a DFS disc, type ?&2A6=0
to temporarily disable the PRES Expansion rom, issue your format command, which will now not be trapped by the Expansion rom, and then just use <Break> or maybe <Ctrl><Break> to restore the PRES Expansion rom. (Just change the &2A6 to match the id of your Expansion rom.)
This method is classed as ‘dirty’ and shouldn’t be used for long-term disabling as it won’t recover any workspace previously claimed by the rom in question but it’s fine for temporary disablement such as is required in this instance.
