Could you take a look at the file `.config` in the build directory of
SeaBIOS and check that everything is set correctly?
How did you capture the log? I guess the serial console, but want to
make sure. I have no idea why the SeaBIOS messages go missing.
You could try to configure build SeaBIOS yourself and add that to the image.
You could try to enable CBMEM console in coreboot and in SeaBIOS. No
coreboot messages will be captured to my knowledge on Intel devices with
FSP software, but maybe the SeaBIOS messages survive. You can read it
out with `cbmem -c` from `util/cbmem/`.

SeaBIOS should load all the Option ROMs.
By the way, what is your use case for SGABIOS?

It worked! Thanks a lot! Two more nitpicks as you use digest mode.
Please update the summary of the message and also add the correct
In-Reply-To header field so that the messages are threaded correctly. I
guess the second thing is not easy to do in Microsoft Outlook. Maybe
just deactivate the digest mode and use the “normal” mode as long as you
are actively communicating with the list.
