        It's easier to to this without objcopy. Modern ld versions support
        --oformat=binary , so just one line does the direct compilation
        job.

        Hi,
        The c code uses function call, why need not set stack (ss:esp)?

        good point @decent. I guess you will need to set up the stack first
        in main, probably in assembler.

             rax is a 64 bit register. A bootloader is running in 16 bits,
             so you cannot use rax (64 bit) or eax (32 bit). You have to
