LFS Kernel Bootsplash -- How??


Has anybody installed on their LFS system a kernel boot-splash screen? I am trying to figure out how to do it for my distro, however before I start, I want to know exactly how to proceed.

I've read several how-to documents (e.g. Slackware Linux 10.2 Bootsplash Quick Howto), however I am not certain what to do for creating the initial ramdisk image. Should I follow the instructions shown in that document, or is there more to it? I am using Grub to boot my system, and not Lilo as indicated in that particular how-to.

Please bear in mind that I have a very minimal CLFS system with only few packages installed from BLFS (X11, DHCP, cdrtools, etc). I can always install more packages, but I would prefer to keep the package-count to a minimum. The system I am using is not a desktop computer, but instead a console unit for a medical device.

Thank you in advance for your assistance.

Thanks for all of the replies.


Anyhow, here's what I found out through research:

To enable a bootsplash startup screen during the initial kernel execution:


1. Rebuild a new kernel with these options enabled:
Code:
CONFIG_FB=y
CONFIG_FB_VESA=y
CONFIG_VIDEO_SELECT=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_INITRD=y
CONFIG_INPUT_EVDEV=y
CONFIG_BOOTSPLASH=y
and with this patch. The patch you need may vary. I am using kernel 2.6.17.13, and this patch worked fine.

2. Rebuild/install grub-0.97, adding the --enable-graphics configure option.

3. Build/install /sbin/splash from bootsplash-3.0.7.tar.bz2 Utility folder.
Code:
# tar xjvf bootsplash-3.0.7.tar.bz2
# cd bootsplash-3.0.7/Utility
# make splash
# cp splash /sbin
4. Obtain a bootsplash theme from this site (or any other of your choice), and install it within a “themes” directory (create it if it does not already exist):
Code:
# mkdir -p /etc/bootsplash/themes
5. Run a command similar to this:
Code:
# /sbin/splash -s -f /etc/bootsplash/themes/yourtheme/config/bootsplash-800x600.cfg > /boot/initrd.splash
6. Update Grub's menu.lst file to include a new entry, or use an existing one if you are brave:
Code:
# vi /boot/grub/menu.lst
title LinuxWithSplash root (hd0,0) kernel /boot/clfskernel-2.6.17.13 quiet rw root=/dev/hda1 vga=788 splash=silent initrd /boot/initrd.splash
7. Reboot and select the (new) entry added to the Grub menu.


NOTES:
a) If you already have an initrd (initial ram disk), then Step 5 above will not work for you. You will need to find an alternate way to append to your existing initrd the data necessary to kickstart the bootsplash.

b) Additional support will be needed if you require a progress bar within your theme. This support needs to be added (somehow) to the start up scripts in /etc/rc.d/init.d. If you figure this out, please let me know how!
