Quick and dirty answer... Go to http://www.kernel.org and download the tarball for needed kernel. Unpack it somewhere (I use /usr/src/linux-2.4.version... althought some people suggest different location). >From this directory run: # make mrproper # vim Makefile (to change a bit the kernel version: from 2.4.9 to 2.4.9.myversion - for example. You may skip this.) # make menuconfig (or 'make config' - plain shell-like or 'make xconfig' - for X version. It didn't worked for me.) # make dep # make bzImage # make modules (if you configured the kernel to use modules. Usually you will.) # make modules_install It may take about an hour.... Of course it may be much faster if you do have a fast machine. On my AMD K6-2 350 MHz it takes about 40 minutes. Then you need to install the compiled kernel where it will be loaded when booting. If I remember it well, you may run 'make install' or 'make lilo' or something other. Just scan READMEs, INSTALLs, and Documentation/kbuild directory. I do it this way: # cp ./arch/i386/boot/bzImage /boot/vmlinuz-2.4..... # cp ./System.map /boot/System.map-2.4...... # vim /etc/lilo.conf add a block for new kernel: image=/boot/vmlinuz-2.4..... label=My_new_kernel ...other options.... # /sbin/lilo And that's all. Usually leave your current kernel default - sometimes your new kernel may fail, so you boot with your old one and run 'make clean' from the directory with kernel source (instead of make mrproper) and go steps from make menuconfig to lilo. If you run 'make clean' then your last configuration is left untouched. make mrproper deletes your configuration, so you start with options default for your architecture. If you have some time (you should have :-) then go to http://www.linuxdoc.org and read the Kernel-HOWTO (http://www.linuxdoc.org/HOWTO/Kernel-HOWTO.html). Also look for README and INSTALL files in your kernel-source directory. Look in the Documentation/kbuild directory. The whole magic is to get familiar with various options in the 'make config' step. (I am not yet too experienced here - still learning). I suggest (but you have to do what you think is right) to select everything as module (if this is possible), and leave default selections for options you don't understand. Most of the steps you can execute as normal user. Only 'make modules' 'make modules_install' and copying may need to be run as root. Make modules - becouse modules not owned by root may be rejected by the module loader. Deeper info you wil find in man pages... I don't remember which ones. I hope that this helps you. --Mariusz -- Określ Swoje potrzeby - my znajdziemy ofertę za Ciebie!
