GRUB

GNU GRUB ("GRUB" for short) is a boot loader package from the GNU Project.

Grub interface

grub> setup (hd1)
grub> quit

Grub splash images

• Find gzipped, 640x480, 14 colour only, xpm images (like the ones here).
• Put the images in /boot/grub/splashimages/.
• Rename the image you wish to use to 'splash.xpm.gz'.
• Make a link to /boot/grub/splashimages/splash.xpm.gz and put it in /boot/grub/.
• Open /boot/grub/menu.lst and below the 'Pretty colours' section add a third line as below:

# Pretty colours
# color cyan/blue white/blue
splashimage=(hd0,1)/boot/grub/splash.xpm.gz

(Note: The hd0,1 refers to hard drive 1 partition 2 where, for an example, a file system could be installed. You'll need to change those numbers if yours differs.)

• That's it. Restart to see the new eye candy. For more in depth explanations:
