Build Kernel

iDog

Use Linux 2.6.12 as an example.

Preperation

• download kernel: http://www.kernel.org/
• backup the current source code if available: (linux below is a soft link)

cd /usr/src
mv linux linux.bak

• unzip the source code downloaded:

tar xvfj linux-2.6.12.tar.bz2

• configuration according to your target machine

cd /usr/src/linux
make mrproper
make menuconfig

• build kernel and install it

make

make modules_install
make install

Check /boot to see that the kernel is installed properly.

• configure grub if it was not done automatically (in 2.6.18, it's surely done by make.)

cd /boot/grub

# edit menu.lst
vi menu.lst

# add following lines:
title Fedora Core (2.6.12_Han_050620)
        root   (hd0,11)
        kernel /boot/vmlinuz-2.6.12_Han_050620 ro root=LABEL=/ rhgb quiet
        initrd /boot/initrd-2.6.12_Han_050620.img

Restart machine, enjoy the new kernel!
