I disklabelled one scsi disk and installed sdboot on it, the vax reads
the bootprogram and kernel and then fails like this:

kernels bootmessages....

sd1 at scsibus1 targ 0 lun 0: <QUANTUM, LP80S  980809404, 3.3> SCSI2
0/direct fi
xed
sd1: 82069 KB, 921 cyl, 4 head, 44 sec, 512 bytes/sect x 164139 sectors
booted from type 42 unit 4 controller 6 adapter 0
boot device: <unknown>
root device: 

Is booting from SCSI possible or?
What can I do?
