Configure Grub boot image (network turn)

The background image of Linux is placed in the/boot/grub/splash.xpm.gz, changing it or changing the splashimage= (hd0,2)/grub/splash.xpm.gz setting is also OK.

However, the images used by grub are required. It must be an xpm file, or a file with gzip-compressed xpm files as a picture background, with an image of 14 colors and a size of 640x480. Use the Convert command to change the format of the picture.

Convert  download.jpg  –geometry  640x480  -colors  splash.xpm

Note that between 640 and 480 is "X", not "*".

Gzip  splash.xpm

Then move the compressed file to/boot/grub/to replace the original file.
