    I stand corrected, it is a real bug and I let it slip in from the folks. I recant the point and error here is mine.

    However, one should note this would only be found if a person was booting
    an add-in card. This is why it has masked its self for so long. Now the
    much harder issue trace is the following. So I am impressed that you
    caught this very tiny bug that would be big and messy later. Tip of the
    hat to you.

    Noting that in the special case of who/what is allowed to have access to
    "ide0/ide1" this is an onboard host and generally would have the results:

    hwif->index == hwif->channel

    If and only if the host had rights and priviledges to "ide0/ide1", would
    it be masked.

    So as the previous offer still stands point to have peace again, I am
    still waiting for a reply on are going to be able to work through the
    inital bumps an bangs from the beginning.
