Building a New Kernel

  • download source from
  • unpack source
    • tar xvjf linux-2.6.26.tar.bz2
  • create configuration (.config) file
    • cd linux-2.6.26
    • cp /proc/config.gz . (If this file does not exist, skip ahead to the alternate approach below.)
    • gzip -d config.gz
    • mv config .config

Alternate method of getting .config:

  • If the file /proc/config.gz does not exist on your system, you can get the required file by issuing the following commands:
  1. yum install kerneldevel
  2. cp /usr/src/kernels/ ./
  • make oldconfig
  • customize your configuration
    • make menuconfig
  • compile kernel and modules
    • make
  • copy kernel image to /boot
    • cp arch/x86/boot/bzImage /boot/vmlinuz-2.6.26
  • copy system map to /boot
    • cp /boot/
  • install the modules
    • make modules_install
  • create initial ram disk image
    • mkinitrd -k vmlinuz-2.6.26 -i initrd-2.6.26 (this did not work for me - mkinitrd considered it do be invalid syntax. Using 'mkinitrd initrd-2.6.26 2.6.26' worked, so try that if the first version gives you problems. - Gregory Masseau)
  • update GRUB
    • vi /boot/grub/menu.lst
  • reboot
