Since SeaBios seems to be bothered about the checksum of the oprom i
tried to disable the checksum_check via:

./build/cbfstool build/coreboot.rom add-int -i 0 -n
etc/optionroms-checksum

But it seems like there is sth. wrong with that vbios.. Multi-coloured
stripes and strange distortions until kernel boots...

I guess i start using UEFITool to re-extract it...


best regards,
