Nazib,
try having a look at :- http://www.linuxdocs.org/HOWTOs/Kernel-HOWTO.html#toc4

the basic method is
1. make menuconfig
or make xconfig
2. make clean
3. make dep
4. make bzImage
5. amend your bootloader config file to pick up the new kernel.

have fun

ps. don't be surprised if your first few attempts fail to compile, and that it takes a long time to compile when you do get it working.

With 2.6 and later we simply type:
make xconfig (or make menuconfig)
make -j2 && make -j2 modules_install && make -j2 install
to compile it (and setting up the bootloader, might not work on all systems though)

(-j2 makes make compile 2 files simultaniously, gives faster compiles on some systems, if you din't know what it is -j2 is good for most (the dafault is -j1 afaik))
