I've tried a bit more, and I'm sure it ISN'T the SCSI code. I will attach
the full boot log from SCSI at the end of this file, but I've also tried by
removing ALL SCSI hardware, including the controller, from my system. It
still hangs with the 'old' 1.2 kernel (I didn't have a 1.2b prerelease
kernel) when netbooting from my linux-machine.

But then again, your machine at least starts, which I cann't say about mine.

OK, but to make the debugging a bit easier, I will copy the whole booting
process, so you (all) see the rest of the process too. Maybe it is some
setting, because I don't have any documentation on this machine...
(I removed some '^H ^H stuff...)
