How to get the correct .config file to compile the Linux kernel kernel specific to my hardware?

I tried to use make defconfigto compile the kernel, but, as expected, it could not boot. I was wondering which kernel .config file is used by kernel manufacturers such as Canonical for Ubuntu, which the kernel can load right out of the box. Of course, I'm still a newbie and am setting up various options, a bit out of my league at present.

In particular, I am looking to download the basic "hello world!" module to my running kernel 2.6.32.41. To do this, I will need to compile the kernel source with the same .config file that was used for the running kernel.

Ubuntu usually patched the kernel (kernel.org) to have its own kernel. If you loaded the stock kernel and tried to use the / boot configuration file (or sometimes you can find the currently loaded configuration file as /proc/config.gz, for example Backtrack Ubuntu based on 10.04 LTS), then u might need to do " make oldconfig "with the current configuration file named" .config ". "make oldconfig" will then use .config to create a new .config that is compatible with the kernel source.
