Mostly it is used to set labels when doing initial +installation procedure. It is started from boot program prompt. +You will here be guided through a session, things with ^^^^ under +is typed in by the user, comments are within /* */. + +Nboot +: edlabel + ^^^^^^^ +11700+576+43200 start 0x0 +With this program you can modify everything in the on-disk +disklabel. To do something useful you must know the exact +geometry of your disk, and have ideas about how you want +your partitions to be placed on disk. Some hints: +The a partition should be at least ~20000 blocks, the +b (swap) is depending on your use of the machine but it +should almost never be less than ~32000 blocks. + +Disk geometry for most DEC disks can be found in the disktab +file, and disknames is listed in the installation notes. + +Remember that disk names is given as disk(adapt, ctrl, disk, part) +when using the installation tools. + +Label which disk? ra(1,0,0) /* See INSTALL text for device types */ + ^^^^^^^^^ +getdisklabel: no disk label +ra(1,0,0): no disk label +(E)dit, (S)how, (D)efaults, (W)rite, (Q)uit) : e + ^ +First set disk type.
