Dear Gérard, David and Joerg! Thank you very much for your suggestions, especially yours, Gérard! Indeed, looking at the SC-200 board it was configured for PCI INT B! Setting the jumper to PCI INT A solved the problem, now I was able to install FreeBSD-4.1R successfully. Again reading the manual of both the motherboard and the controller card PCI INT A is the default setting, it was my mistake to trust on the the right setting without a simple check. But last for years there was no reason to have any look to the controller because the system has worked flawlessly with all previous FreeBSD releases until now. Being happy I want to thank you again, Jens Griepentrog > > On Wed, 23 Aug 2000 14:25:06, Gérard Roudier suggests the following: > > 1) Check that your SC-200 is configured for PCI INT A. > If it is not, change jumpers accordingly. > 2) Move you board to another PCI slot. > 3) Check/set SCSI termination properly. > > If either (1) and/or (2) and/or (3) does not cure, then send me any dmesg > you have.
