    Never having used zlilo, I wouldnae know, but the said system was
    distinctly faster under the UP kernel than the SMP one with the
    following command:

    Q> make -j bzImage

    Please advise how that compares with your sample?

    Meaning ???

    Best wishes from Riley.

    | There is something frustrating about the quality and speed of Linux |

    | in other words, I can implement this XXXX feature, but I bet someone |
