That should work fine.

crossgcc is only needed once.

GRUB boot menu is not showing GRUB2

[Dhanasekar Jaganathan]

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
