一、准备工作：
1)下载一份内核源代码linux-2.6.10.tar.gz
http://www.kernel.org/pub/linux/kernel/v2.6/
2)下载 module-init-tools-3.0.tar.gz" and "modutils-2.4.0-1.i386.rpm"
http://www.kernel.org/pub/linux/kernel/people/jcm/module-init-tools/attic/module-init-tools-3.0.tar.gz
http://www.kernel.org/pub/linux/utils/kernel/modutils/v2.4/modutils-2.4.0-1.i386.rpm
3)安装module-init-tools.
# tar -zxvf module-init-tools-3.0.tar.gz
# cd module-init-tools-3.0
# ./configure --prefix=/sbin
# make
# make install
# ./generate-modprobe.conf /etc/modprobe.conf
4)安装modutils-2.4.0-1.i386.rpm
# rpm -ivh modutils-2.4.0-1.i386.rpm
5)解压缩内核源代码.把下载的源代码包放到目录/usr/src下,然后
# cd /usr/src
# tar xvfj linux-2.6.10.tar.bz2
# cd linux-2.6.10
6)打补丁：linux-2.6-seg-5.patch
http://www.kernel.org/pub/linux/devel/binutils/linux-2.6-seg-5.patch
把linux-2.6-seg-5.patch放到linux-2.6.10 目录：
# cd /usr/src/linux-2.6.10/
# patch –Np1 –i linux-2.6-seg-5.patch (-Np1 ,1 is number 1)
# source ./linux-2.6-seg-5.patch
（忽略出现的错误）
二、配置工作
# make menuconfig
使用i386默认配置 /usr/src/linux-2.6.10/arch/i386/defconfig
三、编译
[# make dep]
[# make clean]
# make bzImage
内核编译成功后，会在/usr/src/linux/arch/i386/boot目录中生成一个新内核的映像文件bzImage.
# make modules (编译可加载模块)
# make modules_install (安装可加载模块)
安装成功后，系统会在/lib/modules目录下生成一个2.6.10子目录，里面存放着新内核的所有可加载模块.
ATTENTION:下一步解决
make install的时候可能会出现如下错误信息：No module BusLogic found for kernel 2.4.20
mkinitrd failed
方法：
# vim /sbin/mkinitrd
...
for n in $scsimodules; do
# for now allow scsi modules to come from anywhere. There are some
# RAID controllers with drivers in block/
findmodule $n
done
...
change to
#for n in $scsimodules; do
# for now allow scsi modules to come from anywhere. There are some
# RAID controllers with drivers in block/
#findmodule $n
# done
# make install (安装新内核)
[四、初始化新内核](因为已经自动做好了下面几步。# ls -l /boot)
# cp /usr/src/linux-2.6.10/arch/i386/boot/bzImage /boot/vmlinuz-2.6.10
# cp /usr/src/linux-2.6.10/System.map /boot/System.map-2.6.10
# cd /boot
# rm –rf System.map
# ln –s System.map-2.6.10 System.map
# new-kernel-pkg --mkinitrd --depmod --install 2.6.10
五、修改grub.conf
# df (查看根目录分区:例如 /dev/hda2)
# vim /boot/grub/grub.conf
做两处修改：
[(1) 将default=1改为default=0]
(2) 将kernel行的“LABEL=/”换成根目录所在的分区(/dev/hda2)
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.6.10)
root (hd0,0)
kernel /vmlinuz-2.6.10 ro root=/dev/hda2
initrd /initrd-2.6.10.img
title Red Hat Linux (2.4.20-8)
root (hd0,0)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
initrd /initrd-2.4.20-8.img
六、
# reboot
