I am trying to change the splash and menu .png, but when I do it fails to show up. I did nothing except mv the old to example "splash2.png" and cp'd the new image over. I also own the user and group over to root, and ensure all permissions are the same as the original. What are the specification for a background in erpxe? Is it the same limitations of GRUB Legacy?
Update: I didnt find the settings detail for images but I will assume they are very similar to GRUB Legacy settings. I ended up just using the original image and pasting my image and to it, then it appeared fine.Good luck to all, and awesome project!
