low-priority ? I mean, you are losing time and effort to try something which

and running on your box ?

mmm, what pegasos revision/model do you have, and what is the date of your
firmware ?

Look at the bapln-gmbh web page.

I could, even beta ones, please mail me privately, but not before next week.
