ok - then you may have to relabel the disks for use under Solaris - had this
problem just the other day with a U60 that had SCA drives that (presumably)
had been used elsewhere. probably you want to make sure that the SCA drives
are attahched properly from the OBP use probe-scsi-all;

ok probe-scsi-all

this should report the two SCA drives, and the CDROM (as well as any other
connected SCSI devices).

assuming that the CDROM is visible from the above check you should be able
to boot from CDROM using ;

ok boot cdrom
