Did you run the VGA BIOS in the coreboot emulator or did you make sure that only SeaBIOS would run it? Note that the default is coreboot, which I think is wrong.
I'm not sure I understand the nuance
coreboot by default tries to run option ROMs in an emulator.
SeaBIOS runs option ROMs on bare metal.
It is redundant and wrong to do both. It is a really bad error that coreboot defaults both to running ROMs *and* using SeaBIOS as default payload. The only thing that makes sense is to have only one. If SeaBIOS is available it should generally be taking care of option ROMs.
I followed the instruction on SeaBIOS page ( http://www.coreboot.org/SeaBIOS#Adding_a_VGA_option_ROM) then I think it's SeaBIOS who managed the VGABIOS.
No.
But I didn't know who ran the VGABIOS really (emulator or SeaBIOS). How can I check it ? All my config was default
Then the configuration is wrong. Disable all the option ROM stuff under Chipset in coreboot menuconfig. Or use this:
git clone http://review.coreboot.org/coreboot && cd coreboot && \ git fetch origin refs/changes/38/1638/1 && git checkout FETCH_HEAD
I pass radeon.modeset=0 to access a console and flash my rom to get my old bios back.
OK, so you did have graphics then?
No, only the console worked, the screen froze when xorg started up.
Console very much counts as working graphics. "not working graphics" means that the screen never shows anything.
Start by fixing the redundant option ROM configuration. See if that helps at all.
