Dear Jean Delvare, am Mittwoch, 31. Dezember 2003 um 22:15 schrieben Sie: >> Well...I don't actually know what the difference between kernel >> modules in 2.4 and 2.6 is.

This is what I did and it works well. JD> Good luck. Feel free to ask questions as they come. Well...I think I could manage to change almost everything according to the guide and other ported files but there where 2 points where I ran into problems: 1. Section "Detect", Device Creation: Do I have to use names from the sysfs-interface-doc here? The problem is, that I couldn't find anything useable here as the bt869 isn't a sensor chip in the traditional way (it does neither read temperatures nor voltages or whatever...). 2. Quite the same problem is at the point where I have to define show and set functions: I should use names from the sysfs-interface-doc but there isn't anything according to the functions which the bt869 has... Thanks for your help! Bernhard Gruber
