Kind of you! Then let me summarize the result of my "meditating" over your sharp analysis.

I admit, concede and agree that relocating the entire process to the top of 'conventional' memory as a first step will be the simplest, safest, if a little... boring? ;-) way to get the job done.

Out of interest however still seeking a reasonably simple way to save my solution from the evil TSR problem. As we saw previously :

Exactly. But if we walked the MCB chain and fixed them MCBs by hand without calling DOS, under CLI it would be completely correct, right ? Alternatively, what about temporary cheating the INDOS flag "up" (instead of CLI) ?
