You distribution should be
normally providing a file in you boot directory with the config
options
like
/boot/config-xxx
IF it is not there also no
problem try these below steps
Install kernel source closest
to your source from kernel.org(check uname -r)
untar it in
/usr/src
Match the Version name in the
Makefile to the exact name of your current running kernel .
enter directory
,
make mrproper
make oldconfig
make menuconfig (and select
the option for the module you wanted and save)
make dep clean bzImage
modules ( dont do modules_install - it will overwrite)
latter do a find for your
module in the kernel source and copy it to approriate path (just in case try
insmoding it first)
in
/lib/modules/<current-kernel-path>/kernel/drivers/<your mod dir> or
where ever
then do a depmod -ae
update your
modules.conf
that's all .
enjoy.....

I have a running kernel without any thing in /usr/src, all that I have now are the folder /lib/modules/x.x.x and bzImage, initrd-xxx.img…, and System.map. I want to recompile the kernel to add only one module. Without .config file, it takes me several hours to go through all the options during configuring ‘make xconfig’ however usually the one I get is not the same as the original, running one ( I am new in kernel). It causes potential problems when I run my existing applications (some modules )
The options in configuration come with : Y (built in) , M (module), N (not included).
I think it is hard to recover .config file with only a few lines of command but I can do that work ‘manually ‘ (with a pen and paper to jot down every option configured)
Any suggestion and thought will be appreciated. Thanks in advance.
