    Bootup parameters

    In the 32-bit startup code "linux\arch\i386\kernel\head.s"

    First 2kB data at real-mode address 0x9000:0000 will be copied to
    protected-mode page: _empty_zero_page, it is for boot parameters,
    and then all these parameters will used or checked in setup_arch()
    function.

    Second 2kB data will also copied to _empty_zero_page + 2048
    position.

    So, I just want to know the first 2kB detail information for a specific
    architecture such as x86.

    I'm not sure you will get an answer to your question in this forum. Most of us don't get down as deep as actually reading the source code. Is there some higher level problem that you need help with?
