I am trying to boot Intel Rangeley CPU/ Mohon Peak board by Coreboot. I am using GRUB2 as a Payload. 

In menuconfig, I have selected, 

Add a payload - GRUB2 

GRUB2 Version - HEAD. 

My mSata has two fedora OS. When I boot the system, I am not seeing GRUB boot load menu. System straightly booted to one of Fedora OS. 

In /boot/default/grub, I have changed GRUB_TIMEOUT = -1 ( which stops the system indefinitely at boot menu in GRUB2). Still system is not stopping at boot menu. 

With other vendor BIOS on my board, I am seeing boot menu. I have observed they were using GRUB 2.02_Beta version. 

So, I have checked out GRUB 2.02_Beta and complied the source which produced grub2.elf. 

And, I have modified Payload as  Add a Payload = An ELF executable payload and given the path of grub2.elf. 

After flashing this BIOS on my board, I am seeing error message, 

FYR, I have attached my .config file, Please view it.

Can you please help me to solve this issue?.

Thanks,
