There's no hard and fast rules but other software when compiled might look in /usr/src/linux cp kernel-2.6.x /usr/src 2. Uncompress the kernel source file tar zxvf kernel-2.6.x.tar.gz (for tar file) tar jxvf kernel-2.6.x.bz2 (for bzip file) 3. ln -s /usr/src/kernel-2.6.x linux 4. cd linux 5. make menuconfig (terminal base), I recommend this. make xconfig (graphical base), since you 're new try this one. 6. make 7. make modules_install 8. make install This is all you have to do. To verify wheather its correctly installed or not, vi /etc/grub.conf (if you don't find the file, then try in /boot/grub/grub.conf). Example: default=1 timeout=10 splashimage=(hd0,6)/grub/splash.xpm.gz title Fedora Core (2.6.5-1.358) root (hd0,6) kernel /vmlinuz-2.6.5-1.358 ro root=/dev/hda8 rhgb quiet initrd /initrd-2.6.5-1.358.img title Fedora Core Custom (2.6.9) root (hd0,6) kernel /vmlinuz-2.6.9 ro root=/dev/hda8 rhgb quiet initrd /initrd-2.6.9.img title Windows XP rootnoverify (hd0,0) chainloader +1 default: This tells the grub the default boot. Remember in grub, it starts from 0. For above example, Fedora Core is 0 and Fedora Core Custom is 1, goes like this. timeout: It tells grub to hold before it boots default kernel. It is counted in seconds. To remove error kernel just comment the line or delete the block, and make sure default to respective number. eg: default=0 timeout=10 splashimage=(hd0,6)/grub/splash.xpm.gz title Fedora Core (2.6.5-1.358) root (hd0,6) kernel /vmlinuz-2.6.5-1.358 ro root=/dev/hda8 rhgb quiet initrd /initrd-2.6.5-1.358.img #title Fedora Core Custom (2.6.9) # root (hd0,6) # kernel /vmlinuz-2.6.9 ro root=/dev/hda8 rhgb quiet # initrd /initrd-2.6.9.img title Windows XP rootnoverify (hd0,0) chainloader +1 To clean up the mess: 1. cd /boot 2. to remove compiled kernel rm System.map System.map-2.6.x vmlinuz vmlinuz-2.6.x 3. Restoring to original, before compile the kernel go to /boot and ls -l so you can note down file name and symbolic link. ln -s System.map-original System.map ln -s vmlinuz-original vmlinuz That's all. Hope you'll enjoy the compling the kernel. Happy compling. -- Sincerely, Aabash Gurung
