    The thing I like about this one is it's focused on 32-bit assembly in protected mode...which is right down my alley.
    may u make it more clear for me...please
    Programming is a high logical enjoyable art for both programer and user !!

    What exactly can I clarify? It teaches you 32-bit protected mode assembly in contrast with the 16-bit real mode assembly AoA teaches.

    The biggest difference is that in protected mode, you can use all 4 GB of memory. You can't in real mode.

    In protected mode, you can "do away" with segments. You'll still have segments, but they will cover the entire 4 GB.

    Real mode is 16-bit. This means that you can only address 16 bits of memory at one time. 32-bit protected mode is 32-bits, meaning you can address 32 bits of memory at one time.

    Since 32-bit protected mode is 32-bits, the code that runs in 32-bit PM is 32-bits. Since the BIOS code is 16-bits, you cannot directly use BIOS interrupts in PM. There's ways around this though (slow, but they work).

    Or you could try something a little different.
