Hi There,

*Step 1
*Download the kernel from below link

ftp://ftp.kernel.org/pub/linux/kernel/v2.6


*Step 2*

Extracting the kernel

if its a archive with tar.gz extension then do below in your /usr/src

# tar -zxvf linux-2.6.x.x.tar.gz

If its a .tar.bz2 then do below in your /usr/src

# tar -jxvf linux-2.6.x.x.tar.bz2


*Step 3

*You must have a folder now in your /usr/src dir with the name of
linux-2.6.x.x just symlink it with dir linux

# ln -sf linux-2.6.x.x linux

Now change the dir to linux

# cd linux

once you are inside the dir issue any of the below commands to configure
your new kernel

# make menuconfig (This will show you a command line screen to configure
the kernel)

or

# make xconfig (This will open up a qt based gui window to configure
the kernel)


Note : -- if you want to configure the new kernel same as of your old
one then you just need to issue the below commands

# make oldconfig && make modules_install && make install


This will install your new kernel with the old config and also install
the boot image and other files in your /boot

*Step 4

*I am assuming now that you have configured your new kernel and ready to
compile it , just follow the below steps

# make && make modules_install && make install





*NOTE - i am assuming you are using grub here for that you need to
select the option on boot for the new kernel

lilo users - here comes my lilo.conf

boot="/dev/hda"
lba32
