Thanks very much for your help, I think that my SCSI buses are properly terminated: They work fine over Windows and ... Taking some ideas from the mail from Patrick Keys: I had success to boot the system from a 2.0.34 kernel diskette (build from the 2.0.34 kernel, taken from Debian 2.1r3) I was unable to boot the system from a 2.0.36 kernel diskette (build from the 2.0.34 kernel, taken from Debian 2.1r3) I had success to boot from a custom 2.2.1 kernel diskette. So I think the problems could arrive from a badly kernel setup or from changes made on the driver. I will use 2.0.34 kernel and I will wait for further help. Yours, Jos=E9 L. = "Robert W.
