That's because the truth is variable. Most modules don't care about most compile-time options. A few do care about some. > Since both of Per's kernels are built from the same sources and identical > except for the SMP/PCM options, either should work with the same set of > modules. You're probably right. On the other hand, it wouldn't surprise me if some modules changed because of SMP. PCM is available as a module itself, so that shouldn't change anything. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
