Re: [coreboot] Support for Gigabyte ga-ma78gm-us2h?

[Alberto Simón Francés]

Thanks a lot for the help, but now I don't even get to the black screen.
Whenever I flash coreboot and reboot the computer, after a few seconds of
black-screen the backup BIOS complains about a checksum fail from the main
bios chip and resets the contents to the original BIOS. I have a few ideas
to try tonight, so I'll try that. Hopefully I'll be able to achieve
something.

Cheers,
Alberto
