Hm, the screen turns black after the few yaboot messages and then stays
that way. My CD contains a directory 2.2.16-2000-07-26, presumably thats
the kernel version. Is there a way to get more output on the screen to see
whats is actually going wrong?
Any hints on how to replace the kernel on a CD image so I can write the CD
again (I use CD-RW) or does a non-standard kernel mean I must use bootx or
some other tool to boot from MacOS? I am not sure about floppies, since
our Mac only has an external USB floppy drive.
Cheers, Stefan
