Boring with this one?

WARNING:
I am not responsible for any damage you made by following this guide, be carefull!

Fix your grub bootloader:
- Save your original stage2 file:

Code:

  $ sudo mv /usr/share/grub/i386-redhat/stage2 /usr/share/grub/i386-redhat/stage2.orig

- Copy stage2 file included here to /usr/share/grub/i386-redhat:

Code:

  $ sudo cp stage2 /usr/share/grub/i386-redhat

- Update your grub bootloader

Code:

  $ sudo grub-install hd0

- Change grub.conf timeout value to 5:

Code:

  $ sudo mousepad /boot/grub/grub.conf
  ...
  timeout=5
  ...

- Reboot

Grub background image:
- I have prepared a nice 640x480 image in thundercats_blue directory

Code:

  $ cd thundercats_blue

- Convert it as 14 colors indexed pixmap, you can use Gimp
- Compress it as a gzip archieve

Code:

  $ gzip -9c splash.xpm > thundercats_blue.xpm.gz

- Copy it to /boot/grub directory

Code:

  $ sudo cp thundercats_blue.xpm.gz /boot/grub

- Change your grub.conf file

Code:

  $ sudo mousepad /boot/grub/grub.conf
  ...
  splashimage=(hd0,0)/boot/grub/thundercats_blue.xpm.gz
  ...

- Reboot. Your grub have a new background image:

Change your bootsplash:
- Since my English not good enough to explain, look at thundercats_blue directory

Code:

  $ cd thundercats_blue

- You can use the original initrd as a template, but we no need the original bootsplash:

Code:

  $ gzip -dc /boot/initrd-splash.img | gzip -9c > initrd-thundercats_blue.img

- To add a new bootsplash to initrd-thundercats_blue.img:

Code:

  $ ../splash -s -f bootsplash.cfg >> initrd-thundercats_blue.img

- Copy the new initrd to /boot directory

Code:

  $ sudo cp initrd-thundercats_blue.img /boot/

- Add a new entry to your grub.conf file

Code:

  $ sudo mousepad /boot/grub/grub.conf
  ...
  title Linpus Linux Thundercats Splash
          rootnoverify (hd0,0)
          kernel /boot/bzImage ro root=LABEL=linpus vga=0x311 splash=silent loglevel=1 console=tty1 quiet elevator=noop
          initrd /boot/initrd-thundercats_blue.img

- Reboot and press any key when grub appear, select Linpus Linux Thundercats Splash entry. The bootsplash will have similar image as grub background image.

A nice bonus, please try initrd-playmate.img. The source image not included

Runtime test your own bootsplash:
- Disable DontVTSwitch option in xorg.conf

Code:

  $ sudo mousepad /etc/X11/xorg.conf
  ...
        Option "DontVTSwitch" "no"
  ...

- Reboot
- Test your bootsplash:

Code:

  $ cd thundercats_blue
  $ sudo ../splash -s -n bootsplash.cfg

- Press Ctrl + Alt + F1 to switch to console mode, you will see your new bootsplash on screen
- Press Ctrl + Alt + F7, you will back to X

Has anyone managed to change the boot image successfully? Not working for me at all, Googled some too but that didn't help me. Would be great to be able to change it to a more personal image, if anyone done it some info would be really helpful

 

Yes, I did What's the problem? You can use my bootsplash file on rapidshare link as a template and follow my guide carefully.

 

Hi Blackhawk, thank you for your reply.

Well at first, when I run grub-install I get following,

Code:

[smlh@localhost online-updater]$ sudo grub-install hd0
Could not find device for /dev/mapper/*
Could not find device for /dev/mapper/*
Could not find device for /dev/mapper/*
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0)   /dev/sda

I tried ignoring it, continued with all the steps mentioned in your thread. At grub it just showed a black screen for 5 secs, before it timed out, then it went on to show the default Aspire One boot splash. Any ideas?

 

It's OK, your boot loader updated successfuly but I guess you still have original stage2 file from Linpus. You can use my stage2 file or re-install grub package from Fedora repo.

Code:

# rpm -ivh grub*fc8.rpm --force
# grub-install hd0

Reboot. If you leave grub.conf as is, you will see Linpus bad logo as grub background

 

hi i have tried your guide but when i get to the

../splash -s -f bootsplash.cfg >> initrd-mysplash.img

i get this error

[user@localhost Downloads]$ ../splash -s -f bootsplash.cfg >> initrd-mysplash.img
bash: ../splash: No such file or directory
