thanks a lot for the fast replies!
I found zenos sdminst-version ealier before, but had no time to check it on my macbook air-
i was at work and wanted to start some autumn-style-timelapse from my office-window- and it is quite late in the year already.
anyhow i figured out by reading in the german chdk-forum that the small parition needs no chdk-folder to boot-
so i managed to update my chdk-version and after that got the sevenup-timelapse-script working- hopefully..
greetz,
Tim
