This document provides instructions for adding a custom wallpaper image to the GRUB boot menu in Linux. It describes how to: 1. Resize the image to 640x480 pixels and convert it to a 14 color indexed .xpm file using GIMP. 2. Save the image in the /boot/grub/splashimages directory and compress it. 3. Edit the /boot/grub/menu.lst file to add a splashimage line that references the new image file. Rebooting after making these changes will display the custom wallpaper in the GRUB boot menu.
