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.
