With the sym driver I was able to boot even with a connected CDROM and I got parity error messages. I examined my jumper settings and saw, that I had set a jumper at the CDROM to enable termination instead of parity checking. But this solved only the parity error messages and nothing else. At the next step I had the idea to make the CDROM responsible for the termination of the SCSI bus and not my TANDBERG streamer, because this one has only a passiv termination. Now I can boot my system with and without the sym driver. Now someone has to close the pr-report.
