+		How to use edlabel
+		------------------
+
+
+Edlabel is a program to edit disklabels on any disks in a standalone
+environment. 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

+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.
