This area contains short proposals (howtos) for solution of special hardware and software problems that happened to appear to myself.
Often the fixing of such a problem is relatively simple, but you have to find out. In case even an extensive internet research did not yield the desired result for me or I found only partial solutions that—perhaps in the correct sequence and supplemented by own approaches—have to be put together, here I suggest some solutions that worked for me.
Of course, there is no warranty that these are applicable in general.
