I bet the solution you mentioned is to build GRUB2 as the payload of coreboot instead of seabios.

Seabios is a legacy bios and support legacy boot, it possible can not load grub2.elf. Please correct me if I'm wrong.

I think memdisk is only a blank disk with grub.cfg and can be created with Linux dd command.

I'm not familiar with GRUB2, waiting for the expert to explain this.

Hello,

Has anybody tried to launch GRUB2 by SeaBIOS as a payload (not grub2 on
MBR)? I am hoping to see grub2 on SeaBIOS boot menu.

I followed the coreboot wiki page to compile grub2:
git clone git://git.savannah.gnu.org/grub.git grub
cd grub
./autogen.sh
./configure --with-platform=coreboot
make

At this point it is not clear to me how to create grub2.elf and what the
role of memdisk is. I would appreciate it if somebody could clarify the
steps.

Thanks!

Wen
