Hi Brandon, Indeed, hexdump mbr would show me the bytes but I want to see the code as instructions. objdump works fine for ELF. Being greedy, the ideal tool would handle all 3 formats. The immediate need is pure binary (like the MBR). A couple of weeks ago I had to resort to an old DOS disassembler for a DOS executable. I'd be much happier with a straight Linux solution.
