Re: Help/info request (in re trip points)

[Lucas Levrel <lucas.levrel@free.fr>]

Hi (once more),

Isn't there anyone who could spare a few minutes to guide me on this?

I found some references to trip_point_?_hyst files, which seem promising, 
but they aren't there in my sysfs, and I cannot create them (e.g. "touch: 
cannot touch `trip_point_4_hyst': No such file or directory").

Thanks.
