my ld version information:
[...]legacybios> ld --version
GNU ld version 2.16.91.0.5 20051219 (SUSE Linux)

I get the right elf file after I executed:
        ld -melf_i386 -e 0xf66e0 -Tdata 0xf0000 -b binary bios.bin -o
bios.bin.elf

here is the elf information:
out/bios.bin.elf:     file format elf32-i386
out/bios.bin.elf

And then I build it as payload of coreboot and then run qemu with coreboot.
I get the following messages in the console:

Is that OK?
Thanks for help. ^_^
