All is based to Suse BootSplash (see http://www.bootsplash.org)
Sorry for my bad english.
Thanks to Andrei for suggestion.

All operation from root.

FIRST STEP
------------

1) Install package bootsplash.tgz

2) Download patch for kernel 2.4.20 (ftp://ftp.suse.com/pub/people/stepan/bootsplash/kernel/bootsplash-3.0.7-2.4.20-vanilla.diff)
	I add this to doc/bootsplash/patch-kernel-2.4.20/ of package

3) Go to the directory containing your kernel sources, and apply the patch.
	cd /usr/src/linux
	patch -p1 < /WHERE_YOU_HAVE_PATCH/bootsplash-3.0.7-2.4.20-vanilla.diff

4) Now compile kernel:
	make menuconfig (or make xconfig)
	You should enable the following options.
	Make sure they are compiled into the kernel, and not as modules

	Code maturity level options  -->
		Prompt for development and/or incomplete code/drivers
	Block devices  --> RAM disk support
	Block devices  --> Initial RAM disk (initrd) support
	Console drivers  --> Video mode selection support
	Console drivers  --> Frame-buffer support -->
		Support for frame buffer devices
		VESA VGA graphics console
		Use splash screen instead of boot logo

   compile and install the kernel

	make dep
	make bzImage
	mv /usr/src/linux/arch/i386/boot/bzImage /boot/bzImagebs

5) Create /boot/initrd (Initial RamDisk)
	splash -s -f /etc/bootsplash/themes/current/config/bootsplash-1024x768.cfg > /boot/initrd

	for change theme you change 'current' link to /etc/bootsplash/themes
	I add 4 themes

6) Add new image kernel to /etc/lilo.conf (this is my):

	image = /boot/bzImagebs
	vga = 791                        #(for 1024x768 64k resolution)
	initrd = /boot/initrd
	append = "splash=silent"   #(for switch to verbose pressing F2 key)
	root = /dev/hdb1              #(hdb1 is my linux hd)
	label = Linuxbs
	read-only

7) Now run lilo and reboot, and you should see your new splash screen (without progress-bar and/or animation).
	lilo
	shutdown -r now


PROGRESSBAR and ANIMATION
---------------------------------

1) Package bootsplash have all required and system is ok ready.
	You manually have to modify /etc/rc.d/rc.M rc.6 rc.S at your like
	!!! REMEMBER TO BACKUP THE ORIGINAL FILE ..FOR POSSIBLE NECESSITY !!!

The line to add is:

. /etc/rc.d/rc.bootsplash (at beginning of file)
progressbar XX           (where you want, replace XX with numeric value of percentual)
animate startup          (start animation)
animate shutdown         (stop animation)


For your help I add my personal file to directory usr/doc/bootsplash/samples of package
 	!!! DON'T USE THIS FILE, IS ONLY FOR SEE WHERE I ADD LINE !!!

It is all.

P.S.
