+
+Here is an example of what the partition information may look like once
+you have entered the disklabel editor. Disk partition sizes and offsets
+are in sector (most likely 512 bytes) units. You may set these size/offset
+pairs on cylinder boundaries (the number of sector per cylinder is given
+in the `sectors/cylinder' entry, which is not shown here).
+Also, you *must* make sure that the 'i' partition points at the MSDOS
+partition that will be used for booting. The 'c' partition shall start
+at offset 0 and include the entire disk. This is most likely correct when
+you see the default label in the editor.
+
+Do not change any parameters except the partition layout and the label name.
+
+[Example]
+10 partitions:
+#        size   offset    fstype   [fsize bsize   cpg]
+  a:   120832    10240    4.2BSD     1024  8192    16   # (Cyl.   11*- 142*)

+
+As a reminder, installing the `etc' binary set is NOT recommended.

+installation process.
+
+Default answers are displayed in brackets after the questions.
+You can hit Control-C at any time to quit, but if you do so at a
+prompt, you may have to hit return.  Also, quitting in the middle of
+installation may leave your system in an inconsistent state.
