    Looks kinda black magic... How can I do this is at boot when I do not have a
    kernel to run a program?

    So I repeat my question - does a utility capable of determining if we run on
    an SMP or UP system AFTER UP kernel is booted exist? If so, please point

    If such a utility does not exist or can't be run AFTER the kernel is fired,
    it's the imperative to have SMP kernel boot and work reasonably stable on
    any UP machine... It has not to be blazingly fast, but it has to work stable
    enough for the distro installation to complete.

    Yes, it does. But we can't consider it as our future. How long they are
    supposed to live? I do definitely consider i386 obsolete...
