第四步>
a> make mkproper 清除旧的设定
b> make dep 产生依赖
c> make bzImage 编译内核
d> make modules modules_install 编译模块
e> cp /usr/src/linux/arch/i386/boot/bzImage /boot/bzImage-2.4.20
第五步> 安装bootsplash的工具软件和主题图片
# tar jxvf /patch/bootsplash-3.0.7.tar.bz2
# tar jxvf /patch/Theme-NewLinux.tar.bz2
# cd bootsplash-3.0.7/Utilities
# make all
# cp fbmngplay fbresolution fbtruetype splash /sbin
# cd ../../
下面这几步必须要做，不然在用splash命令时就会出现类似下面的错误:splash:/etc/bootsplash/themes/Linux/images/silent-800x600.jpg不存在。这个其实是由于主题的配置文件中做了绝对路径设定。
# mkdir /etc/bootsplash
# mkdir /etc/bootsplash/themes
# cp -a NewLinux /etc/bootsplash/themes/
我们来看一个完整的主题配置文件，以800x600分辨率为例，文件名为bootsplash-800x600.cfg，可以用vi进行编辑，####开头的为笔者加的注释。

第七步> 将脚本splash.sh拷入/etc/rc.d/下，并修改splash.sh和rc，建议在修改rc脚本文件前进行备份(cp rc rc.bak)
# cp bootsplash-3.0.7/Scripts/splash.sh /etc/rc.d
下面来看完整的splash.sh脚本文件，要想这个脚本起作用，必须修改rc脚本，通过rc脚本调用splash.sh脚本，需要赋予splash.sh脚本可执行权限。需要一些shell script的知识。网上很多，google吧。
我现在的/etc/rc.d/splash.sh脚本，删除了原来放在这个脚本中的绘制进度条部分(调试不成功)和播放动画部分(还没有实验)，以及不适用于red hat linux的一些命令。这个脚本现在只打印类似“booting the system"和"shutting down the system"的信息和实现关机时的silent mode。
#!/bin/bash
#
# splash.sh - This shell script triggers bootsplash actions during
# system boot/shutdown. It can be run by the init scripts repeatedly
# specifying the currently executed system script.
#
#rewrite this script at the base of offered by http://www.bootsplash.org
#line with ### added by me
_procsplash="`cat /proc/splash 2>/dev/null`"
###give the variable "THEME" the name of the directory which the current
###silent mode picture stored
THEME="NewLinux"
test ! -d "/etc/bootsplash/themes/$THEME" && exit 0
# assertions
test -r /proc/splash || exit 0
test -z "`echo $_procsplash|grep on`" && exit 0
####"Yast" is a utilies for SuSE Linux,no for RedHat Linux
####maybe we can erase it
test "$1" == "bootnetwork stop" -o "$1" == "YaST" && exit 0 # no progress
# We chose verbose in grub
test "`cat /proc/cmdline |grep "splash=silent"`" == "" && exit 0
if [ "$PREVLEVEL" == "3" -o "$PREVLEVEL" == "5" ]; then
###no below ,no silent mode when shutting down
if [ "$RUNLEVEL" = "3" -o "$RUNLEVEL" == "5" ]; then
exit 0
fi
### but why ?
fi
# acquire data
#
_shutdown="no"
_silent="no"
test "`cat /proc/splash |grep silent`" && _silent="yes"
test "$RUNLEVEL" == "6" -o "$RUNLEVEL" == "0" && _shutdown="yes"
test -f "/etc/bootsplash/themes/$THEME/config/bootsplash-`fbresolution`.cfg" &&
. /etc/bootsplash/themes/$THEME/config/bootsplash-`fbresolution`.cfg
#
# Print text string. (Booting/Shutting down the system. Press
# F2 for verbose mode)
#
###switch to slient mode when shutdown or reboot the system
test "$_shutdown" == "yes" && ( echo "silent" >/proc/splash; chvt 1)
###print infomation at the area predifined by config file "bootsplash-800x600.cfg"
_boot="Booting"; test "$_shutdown" == "yes" && _boot="Shutting down"
###is the area for infomation defined? yes ,print info, no,run on
if [ "$text_x" != "" -a "$text_y" != ""
-a "$text_color" != "" -a "$text_size" != "" -a "$_silent" == "yes" ];
then
fbtruetype -x $text_x -y $text_y -t $text_color -s $text_size
"$_boot the system ..."
fi
[/code:7b9eb010fc]
下面来看rc脚本（此为系统脚本，决定runlevel和kill or start services，修改前要备份一下，到时要改回来只要覆盖一下就好了cp rc.bak rc）。下面是我现在的/etc/rc.d/rc脚本，定义一个函数，for循环中调用它，以绘制启动进度。重新写了几行代码，绘制进度条。以运行级下的服务总个数和已经启动的服务个数之比作为progress bar的进度，这样进度条显得均匀了一些。
现在这个可以实现以下功能，开机silent模式，有开始画面，有进度条，进度条下有booting system 提示。关机时切换到silent模式，有画面。提示shutting down the system.
不过在开机的时候，有一半时间进度条是空的(系统在加载内核，检测硬件)，在关机的时候，进度条一下子就满了，然后又变空，直到关机。呵呵，回头再改，告一段落了先。

第八步> 修改(bootloader) grub(或者lilo)。我用的是grub，硬盘是ide的。只列出需要修改的部分。我的硬盘分区swap,boot,/。
title Red Hat Linux (2.4.20+bootsplash)
root (hd0,0)
kernel /bzImage-2.4.20 ro root=/dev/hda3 vga=788 splash=silent
initrd /initrd-splash.img
title Red Hat Linux (2.4.23)
root (hd0,0)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
initrd /initrd-2.4.20-8.img
788为800x600模式，791为1024x768模式。这里的模式选择要与图片的大小一致。
到这里就可以重新启动了。呵呵，大功告成。赶紧实验一下，享受自己的全画面Linux启动吧。
********遇到的问题*******
启动不了内核
1/ 提示Kernel panic: VFS: Unable to mount root fs on 00:00
这个大概是因为没有指定根分区，确定你的根分区编号，修改root=LABEL=/为root=/hda* 或者root=/sda*
2/ error 15:can't find file
这个应该是initrd*.img文件找不到，确认grub.conf中指定的文件在/boot目录下。
