S%=A4t happens, I've been there myself when my old ThinkPad and some orange=

juice met each other :(

That was an easy one! I did comment out the calls to do=5Fprom=5Fcopy=5Fnod=
e in=20
src/kmod/Linux/misc.c, the function prom=5Fcopy=5Fnode now looks like this:
static int
prom=5Fcopy=5Fnode( char *dest, struct device=5Fnode *dn, int bufsize )
{
        int ret;

        if( !dest )
/*              return do=5Fprom=5Fcopy=5Fnode( NULL, dn ); */
                return 0;

        if( verify=5Farea(VERIFY=5FWRITE, dest, bufsize) )
                return -EFAULT;

/*      ret =3D do=5Fprom=5Fcopy=5Fnode(NULL, dn); */
        ret =3D 0;
        if( ret < 0 || ret > bufsize )
                return -EFAULT;

/*      do=5Fprom=5Fcopy=5Fnode( dest, dn ); */
        return 0;
}

And it WORKS!!!! I was able to boot the MacOS 9 install CD and install=20
MacOS9!
But console video is incredibly slow :-( It takes about 5-6 seconds to=20
draw the folder opening animation...
What can I do about it? Console video is supposed to be the fastest,=20
right? The Matrox G200 in my box works othervise pretty good under=20
linux...

VNC video is reasonably fast, though. I haven't tried xvideo yet...

It's great watching an old RS/6000 running a modern MacOS!

Thanks a lot, Samuel!

PS. Should I worry about the following lines?
...
Unknown processor id (0009)
Running in PowerPC G3 mode
Warning: CPU node missing from hardware tree!
The calibration will probably be wrong... will try running anyway.
Please contact your favorite MOL developer about this problem.
