Recent /sbin/installkernel installs config along vmlinuz and System.map in /boot. If you use make install to install kernel, you should have it there. Recent kernels have a special option, that compiles the config into the kernel and it then appears somewhere in /proc. If you have turned on that option, you should have it there. Otherwise, you will have to build the kernel from scratch.

It's simply not possible. You could guess some options by looking at the symbol listing, but not all of them. > Any suggestion and thought will be appreciated. > Thanks in advance. ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@xxxxxx>
