http://www.bootsplash.org/ Kernel stuff ATTENTION! Please read the following information very carefully. This kernel patch is free software; you may redistribute it under the terms of the GNU General Public License. This kernel patch comes with absolutely no warranty. Requirements * To use the Linux bootsplash screen, you have to recompile your kernel. If you are not familiar with this procedure, please ask one of your geek friends or get hold of a distribution that already comes with the bootsplash screen. * You need a bootsplash theme. * You need the splash utility, see README.bootsplash Otherwise lets get started: Patching and Compiling the Kernel First off, make sure, your kernel sources are installed in /usr/src/linux. Now download the latest version of the bootsplash patch: * bootsplash version 3.0.7 (created 2003/03/10 against vanilla Linux 2.4.20) ftp://ftp.suse.com/pub/people/stepan/bootsplash/kernel/bootsplash-3.0.7-2.4.20-vanilla.diff yourbox:~ # cd /usr/src/linux yourbox:/usr/src/linux # patch -p1 < /path/to/bootsplash-3.0.7-2.4.20-vanilla.diff patching file drivers/char/console.c patching file drivers/char/keyboard.c patching file drivers/char/n_tty.c patching file drivers/video/Config.in patching file drivers/video/Makefile patching file drivers/video/fbcon-jpegdec.c patching file drivers/video/fbcon-jpegdec.h patching file drivers/video/fbcon-splash.c patching file drivers/video/fbcon-splash.h patching file drivers/video/fbcon-splash16.c patching file drivers/video/fbcon.c patching file include/video/fbcon.h patching file kernel/panic.c yourbox:/usr/src/linux # Now you have to change your kernel configuration, using make config, make menuconfig or make xconfig. Go to "Console drivers" -> "Frame-Buffer support" and select "VESA VGA graphics console" (or possibly another framebuffer driver, if one is available for your graphics hardware) and turn on "Use splash screen instead of boot logo". Also be sure to enable "Initial Ramdisk support" in "Block Devices" Save your new config and compile a new kernel. Copy the kernel to your /boot directory and make sure that you have a boot entry for it in your bootloader config. Preparing the picture As there are no filesystems accessible when the bootsplash is first shown, it can be attached to an initial ramdisk. If you dont have an initial ramdisk normally, just use an empty one. Get the sources of the splash utility from: ftp://ftp.suse.com/pub/people/stepan/bootsplash/rpm-sources/bootsplash/splashutils.tar.bz2 # cd ~/splash # tar xvjf splashutils.tar.bz2 splashutils/ splashutils/Makefile splashutils/splash.c [..] splashutils/ChangeLog splashutils/COPYING # cd splashutils # make splash gcc -Os -Wall -c -o splash.o splash.c gcc -Os -Wall -o splash splash.o strip splash # cp splash /sbin/ # cd .. Next you need to attach the picture plus a header, defining text windows and such to the initrd (in the example, this is done for 1024x768. specify other resolutions, if available) : /sbin/splash -s -f /etc/bootsplash/themes/yourtheme/config/bootsplash-1024x768.cfg >> /boot/initrd.splash If you want to use more than one resolution for the bootsplash, call the above command several times, once for each resolution config file. Finishing up run lilo, if appropriate, and reboot your system. You should get the bootsplash screen. During boot you will likely see the following in your messages: vesafb: framebuffer at 0xf0000000, mapped to 0xdc816000, size 65472k vesafb: mode is 1024x768x16, linelength=2048, pages=41 vesafb: protected mode interface info at c000:5137 vesafb: scrolling: redraw vesafb: directcolor: size=0:5:6:5, shift=0:11:5:0 Looking for splash picture.... silenjpeg size 11165 bytes, found (1024x768, 4912 bytes, v3) Got silent jpeg.
