You put what where?!
Pictorial view of FAILOVER_SIZE, _ROMBASE. ROM_IMAGE_SIZE, PAYLOAD_SIZE, ROM_SIZE, ROM_SECTION_SIZE, HAVE_FALLBACKBOOT, HAVE_FAILOVERBOOT for Options.lb and Config.lb.
Some Errors you might come across and probable solutions
Error:
./buildrom linuxbios.strip linuxbios.rom payload 0x70000 0x7f000
linuxbios image is 458820 bytes; only 458752 allowed
Linuxbios input file larger than allowed size!
Solution:
Typically caused by crt0 having a .data segment. Make sure all rom data is defined as constant.
Error:
gcc -m32 -nostdlib -nostartfiles -static -o linuxbios -T ldscript.ld crt0.o

make: *** [fallback/linuxbios.rom] Error 1
Solution:
Increase the ROM_IMAGE_SIZE of the failing piece. In this case the fallback image.
