Hi Viktor,
Yes, I think having option roms checked is probably required. The
only other thing I'd recommend is to build SeaBIOS outside of the
coreboot structure and pull it in as an elf payload. Building within
coreboot is handy, but it doesn't offer the flexibility or control that
you get building it yourself.

Hello,
I've been trying to boot grub installed on the hard drive using
coreboot and
SeaBIOS as a payload. The motherboard I'm using is Intel Mohon
Peak. Also, I
do not use VGA for output, only serial port. So, I included the
sgabios into
my rom file. Here is its layout:
It should have worked. How did you build SeaBIOS, what SeaBIOS config
did you use, and what changes have you made to SeaBIOS?

As I recall, Mohon Peak uses 0x2f8 for the console serial port. Did
you set sgabios to output to 2f8 instead of 3f8 in sgabios.h?
sgabios.h:#define COM_BASE_ADDR 0x3f8

Thank you for your replies!
Just checked sgabios.h and changed serial port base address to 2f8.
Somehow I missed it earlier, although I did set this parameter in both
coreboot and SeaBIOS before. Sadly, I do not currently have access to
Mohon Peak, so I can't really test this right now but, hopefully, I
would be able to test this in a few days.
Also, I'd like to clarify one more thing. Should Option ROMS parameter
in SeaBIOS menuconfig be checked for sgabios to work? Are there any
other nuances I should keep in mind?
