My problem looks in particular the configuration of the kernel with xconfig. There is one thing I do not understand. Obviously when I install Linux (Mandrake 9) I care not for the kernel configuration, I let the distro. But when I run the xconfig this times, lots of options are already enabled. Does it correspond to the kernel configuration as installed by the distribution or is there a difference? The problem is that I do not find a file type kernel.config, and I just recompile changing some options.
