从www.kernel.org上下载最新的内核源文件linux-2.4.20.tar.bz2，并于rh8上编译。
1. cp linux-2.4.20.tar.bz2 /usr/src
2. cd /usr/src
3. tar xvfj linux-2.4.20.tar.bz2
4. ln -sf linux-2.4.20 linux
5. cd /usr/src/linux
6. make mrproper
7. cd /usr/include/
9. ln -sf /usr/src/linux/include/asm-i386 asm
10. ln -sf /usr/src/linux/include/linux linux
11. ln -sf /usr/src/linux/include/scsi scsi
12. make menuconfig
13. make dep
14. make clean
15. make bzImage或make zImage
16. make modules
17. make modules_install
18. depmod -a
19. cp /usr/src/linux/System.map /boot/System.map-2.4.20
20. cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.4.20
21. cd /boot
22. ln -sf vmlinuz-2.4.20 vmlinuz
23. ln -sf System.map-2.4.20 System.map
24. /sbin/mkinitrd /boot/initrd-2.4.20.img 2.4.20
25. vi /etc/rc.sysinit，将keybdev替换成usbkbd，mousedev替换成usbmouse.
25. Grub启动, 在/etc/grub.conf中增加
title Red Hat linux (2.4.20)
root (hd0,0)
kernel /vmlinuz-2.4.20 ro root=/dev/hda2
Grub不需再次调用命令，自动生效。
重启以后就可以用新内核了。
