        I /may/ eventually upgrade to yaboot to get XFree86 4.x (or use
        a 2.4 kernel).

        Yes, annoyingly so. I tried to find documentation for making

        ones that people use.

        Just try it on your existing MacOS partition. You may not need
        a separate boot partition.

        I played with this stuff briefly and I found that I couldn't get
        Open Firmware to recognize yaboot as something it can run unless
        I used the hfsutils and set the proper type/creator to make it
        appear as a MacOS ROM file.

        Note, however, that I have /not/ yet made the switch from BootX.

        You might also try playing with Apple's System Disk utility
        instead of yaboot. See:

        P.S.: This lack of documentation is a gripe about Terrasoft.
        They /should/ have all this stuff right on their web page and
        in their documentation. Instead, they have a mailing list
        archive that is fairly broken (double search results, or none)
        and a poor FAQ (where the stuff isn't even in the form of a
        question -- would never fly on Jeopardy). "What? System Disk
        can be used to boot Linux on a Mac? Quick! Update our web
        pages with the info!" But no... Sigh...
