Re-compiling kernel.

I'm sure this topic has been beaten to death but I just want to make sure I get it right. I feel like I've learned a lot about linux but need to become adept at compiling since I avoid it a lot.

I used genkernel to compile my kernel when I first installed and just went with most of the default options and selections. Now though that I've learned more about gentoo and linux in general I'd like to recompile the kernel with some extra options that I didn't know existed.
I don't plan on using genkernel to compile this time. What I'd like to do is also delete a lot of the options that were selected that I know I don't need to decrease the size of my kernel.

Should it be of any significance that I used genkernel the first time? I can just simply change the stuff I don't want and add the stuff I do in menuconfig and then recompile right?

Also is this generally considered the proper code for compiling the kernel with modules?

Hi,
Kernel compilation is pretty easy, just make sure that you have a working one in your boot partition and the proper entries in lilo / grub so you have an option if you screw up. AFAIK you should be able to "make menuconfig" and pick and choose your options even though you originally used genkernel.

they are not all necessary.
make dep, that is important.
make clean is a good idea.
make bzImage, does just that, and is not needed if you aren't looking for a bzImage
make modules and make modules install only need to be executed if you want any new modules you added since last time you ran them.

so... if you are just updating your bzImage, not modules, and not upgrading to a new kernel, just do make dep && clean bzImage
if you just want to add new modules do make dep&&make clean modules modules_install
that can save a lot of time, sometimes.

Unless I am mistaken, 'make dep ' and 'make clean' are no longer reccomended with the new 2.6 kernels.

On the box it said it was designed for Win XP or better, so why won't it work with Linux?

thanks for warning me, but i have not used the 2.6 series yet, as the DRM/GL is broken...

Hmm...Okay. Cool. I was always under the impression though that you had to recompile the modules too, everytime you recompiled the kernel. That's cool though. So are the modules stored somewhere seperate of the kernel?

Peace

I went into /usr/src/linux-2.4.20-gentoo-r6 and did make menuconfig and added and changed what I wanted. Then I did
