How to make Kernel?

im a complete noob and i tried looking for it, but it seems that the small little things, are never listed because everyone knows it so im left to ask about it.

how do i make or recompile my kernel?
this is what i did so far, im not sure if i did or not, nothing seemed to change yet.

If /boot is on another partion then mount it and type make install. After that you need to setup your boot loader to load the new kernel.

EDIT: Darn it! People here respond too fast...
EDIT: Ignore this... Look below... If that is what your kernel is supposed to be named, then make install didn't copy it. copy it manually and edit your lilo.conf manually (instructions yada yada are at the link below...) Or, try ls /boot and see if it really does exist... if so, lilo is doing something odd...

EDIT: I am really slow today... It looks like you just need to update lilo.conf to point to the new kernel you have, it looks like your lilo.conf is looking for your old kernel...

I'm not sure, but did you actually change stuff when you did make menuconfig? I mean, go into the different categories and enable the relevant options? If so, and you did the other two commands you listed, your kernel is built!

However, even though the kernel is built, you aren't done...
Read this: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=7#compiling

Read starting at the paragraph above code listing 12. Then preform the commands in code listing 12, adjust them to the filename of whatever exists and all that...

After that, finish reading the guide (well, except the parts not relevant to your architecture)! And have fun with gentoo. And keep a very broad definition of fun... I am a little cynical since my nVidia drivers are farked... Such is life.

EDIT: the reason im doing this is to install APM, seems whatever i do i cannot turn off the laptops monitor

i saw the files there in boot and i guess u were right about lilo being weird. well i just did a reboot and i check the make menuconfig to see if the settings stayed and they were there. so im assuming that since it booted and the settings are there, the kernel must have been recompiled and working. right?

Newbie here, trying to help. so, if I screw up, dont hurt me.

But, did you actually copy your new kernel over from /usr/src/linux to /boot ? that would explain

no i didnt copy anything over to boot, i thought "make install" did that?

you should have read over the Handbook, man.

This part here describes how to deal with the kernel in great detail, from configuring the compile options, to how to put it where it belongs.

Make install copies it to /boot/vmlinuz* where * is replaced with -2.6.7-love5 or whatever the rest is. Just type ls /boot to see what's inside. Then since it seems like you use lilo, edit /etc/lilo.conf to include that kernel and then run lilo again. Or you can use GRUB like me and just edit the configuration file without having to re-run GRUB. :wink:
