I tried not to include any VBIOS file in coreboot ROM much earlier, in my first tests. With 'Run VGA Option ROMs' option checked the board just hung.
And as I mentioned in my previous email VGA works fine with vendor's BIOS. So the card itself should be fine.
Sadly, I don't have another card to try. Even if I had, I still would need to make this one work somehow as Mohon Peak is just a reference board and the target board will have a similar VGA controller.
So please, let me know if there are some other things I could try or if I am mistaken somewhere.
Hi Viktor,
It seems you've tried a bunch of different configurations. However, this is making your trouble report hard to understand as it becomes unclear which config had which results.
If you have an external VGA card, then please build coreboot with CONFIG_VGA_ROM_RUN, CONFIG_ON_DEVICE_ROM_RUN, CONFIG_VGA_BIOS, and CONFIG_PXE_ROM all disabled. Please use either the SeaBIOS provided by coreboot, or build SeaBIOS with a default config (only CONFIG_COREBOOT and if needed CONFIG_DEBUG_SERIAL changed from the seabios defaults). This is described at: http://www.coreboot.org/SeaBIOS
In particular, there should be no "pciXXXX,YYYY.rom" or "vgaroms/XXX" files in your cbfs rom.
If the above does not work, please use the above config and recompile SeaBIOS at debug level 8, and post the full debug log along with the output of "cbfstool print".
Cheers, -Kevin
