My apologies for posting, if this is the wrong forum.
I would like to add SeaBios to my coreboot.rom (google_stout.2817.52.0) for a Lenovo X131e chromebook (Celeron 1007u cpu, 4 GB ram, 8 MB Winbond bios flash chip).
I was thinking of building seabios using the repository at https://chromium.googlesource.com/chromiumos/third_party/seabios/+/master/sr... and come up with a SeaBios.CBFS file as suggested in the 15th post in https://plus.google.com/117057264318218846563/posts/FXn39JtNUAa
Since the above article is for a Pixel chromebook, where would I insert/merge this SeaBios file with the backup.bin file that I read from the Winbond chip with flashrom -p internal -r backup.bin -o backup.log
The merged file would be "newrom.bin" which I can then hopefully write with
flashrom -w newrom.bin
In the linked article they suggested flashrom -w image.rom -i RW_LEGACY but that is for the Pixel chromebook (which has the legacy boot).
The Lenovo X131e does not have legacy boot (so there is no RW_LEGACY section, just "fallback/payload".
Should I replace the "fallback/payload"section in my current backup.bin file with the new SeaBios??
