This server has a single scsi disk, da0. I can boot fine. I then plug in a fibre card and attach a fibre disk, which I want to be da1, so that I can boot as normal. However, now the boot stops at mountroot> because apparently fibre is identified as da0 and the scsi disk as da1, and I cannot boot from da0 anymore. What is the solution to this? Is there some device.hint option to say that fibre must be after the scsi disk? Or maybe some fibre delay, long enough to ensure it's found only after root has been mounted? Thanks Anton
