Seabios / Coreboot / splash

[Johan S]

Hi all,

Yet i can't get a splash i almost certain having done things right:

johan@debian:~/coreboot$ strings build/coreboot.rom |grep -i splash
(bootsplash.jpg
johan@debian:~/coreboot$ strings build/coreboot.rom |grep -i vga
VGA_

/home/johan/bootsplash2.jpg JPEG 800x768 800x768+0+0 8-bit sRGB 47.1KB 0.000u 0:00.019

As a result i get a screen @1024*768 , displaying press F12 ... but no splash

Can't figure why ...
Can someone give me pointers ?
Thanks

The seabios debug log is needed to diagnose seabios problems:

http://www.seabios.org/Debugging

The wiki appears to be down right now, but a mirror is at:

The size of the image must exactly match the resolution of the screen
(1024x768 vs 800x768).  See:
