That indeed doesn't look good.
For some reason, the ELF objects have two load addresses: 0x00002000
and 0x080480d4. Therefore objdump generates a full 128MB dump filled with
zeroes. It possibly has to do with recent binutils - this grub 0.97 is
already more than 8 years old.
I wouldn't spend too much effort on grub anymore, and instead focus on
grub2.
Regards,
Arnout
