Hi there,
i m trying to understand few mechanism in coreboot can someone help ?
I grabbed the git tree , made crossgcc , made a biosfile tested succesfully within qemu.
In the menuconfig few options are quite confusing especially looking at the vgabios .
I choose the oldest qemu model for emulation , enabled the vgabios , kept the vesa framebuffer
did the edid patch to bypasse vbe mod multiple ...
but i can't get my splashscreen :-/

johan@debian:~/coreboot$ file build/coreboot.rom ^C
johan@debian:~/coreboot$ build/cbfstool build/coreboot.rom print

I read somewhere that in vgabios i should be able to see :

under "VGA ROM ---> VGA Hardware Type" select "coreboot linear framebuffer"


Anyway i can get my os to boot , i can pass the F12 boot option , i can pass openfirmware but ...
i can't even understand why with all requirement in the biosfile i could't get 1024*768
jpeg displayed with vesa enabled ...
I 'm lost
Thanks
