Hi Nico,
I have taken the Flash Region's dump of my vendor BIOS using Ifdtool (which is copied below),
*FLREG0: 0x000f0000* * Flash Region 0 (Flash Descriptor): 00000000 - 0000ffff * *FLREG1: 0x07ff0200* * Flash Region 1 (BIOS): 00200000 - 007fffff * *FLREG2: 0x00000fff* * Flash Region 2 (Intel ME): 00fff000 - 00000fff (unused)* *FLREG3: 0x00000fff* * Flash Region 3 (GbE): 00fff000 - 00000fff (unused)* *FLREG4: 0x00000fff* * Flash Region 4 (Platform Data): 00fff000 - 00000fff (unused)*
From this dump, BIOS region is from 0x200000 to 0x07FFFFF.
So *CONFIG_ROM_SIZE is 8MB *and *CONFIG_CBFS_SIZE is 6MB ( 0x7FFFFF - 0x200000 = 0x5FFFFF)*
Am I correct?
Please correct me, if I am wrong.
Thanks, Dhanasekar

Hi Nico,
Thanks for the info..
Actually, I have given "*make al*l" to rebuild the coreboot source.
Is it correct way to rebuilt to the source?
That should work fine.
Or I have to run *make crossgcc-i386 CPUS=$(nproc)* and *make*
crossgcc is only needed once.
Nico
Thanks, Dhanaeskar

Hi Nico,
Following is my complete Payload setting,
1.Add a payload -> (GRUB2) 2.GRUB2 version -> (HEAD) 3.Include GRUB2 runtime config file into ROM image = Y 4.Gave the path of grub.cfg (which I copied from Fedora OS when booted
is
booted with other BIOS vendor).
Based on this, please provide your comments.
I can only repeat myself: With this setup, you have to rebuild your coreboot every time you make changes to your grub.cfg. (You probably know that already and did so, but didn't tell it?)
