Template for installing Kernel 2.6.39.4

type `su -` to become root... then do this:

mkdir hold
cd hold
yum -y groupinstall "Development Tools"
yum -y install ncurses-devel qt-devel gcc wget
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.39.4.tar.bz2
tar -xjvf linux-2.6.39.4.tar.bz2 -C /usr/src
cd /usr/src/linux-2.6.39.4
make menuconfig
   (a menu comes up, just hit [tab] [enter] and answer yes to get the defaults)
make
   (if you did it right, this will take a LONG time)
make modules
make modules_install
make install
sed -i 's/^default=1/default=0/' /boot/grub/grub.conf
