Looks like a difference between our versions of 'ld'. The build effectively does: ld -melf_i386 -e 0xf66e0 -Ttext 0xf0000 -b binary bios.bin -o bios.bin.elf I'm not sure why it builds a different elf on your machine. Can you try modifying tools/buildrom.py so that it uses "-Tdata" instead of "-Ttext"? Myles, maybe this was the same problem you were seeing? -Kevin -- coreboot mailing list [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
