Ok, used a different cdrom drive.
Now the Amiga boots but:
[A] While loading Workbench it says: "cannot open device scsi.device unit 5"
then it says: Intution is attempting to reset the worbench screen. Please close all windows except drawers.
I cancel these and use find device from idefix97 and it finds the cdrom drive so i select use
But the cdrom drive is not seen on the workbench screen even with a cdrom inserted
