Is it possible to fix grub to be as graphical as lilo? (talking about the text in the wiki about lilo)
Perhaps you are looking for something like this . . .
spashimage=(hd0,0)/grub/biosplash.xpm.gz color light-blue/black light-cyan/red
The problem is that Grub itself do not include support for background image. That support comes from a patch that ATM Arch grub package lacks.
You can try my package, but you need to compile it.
