110Here is an example of what the partition information will look like once
111you have entered the disklabel editor. Disk partition sizes and offsets
112are in sector (most likely 512 bytes) units. Make sure all partitions
113start on a cylinder boundary (c/t/s == XXX/0/0).

150This program is designed to help you put NetBSD on your disk,
151in a simple and rational way.  You'll be asked several questions,
152and it would probably be useful to have your disk's hardware
153manual, the installation notes, and a calculator handy.

161This program is designed to help you upgrade your NetBSD system in a
162simple and rational way.
163
164As a reminder, installing the 'etc' binary set is NOT recommended.
165Once the rest of your system has been upgraded, you should manually
166merge any changes to files in the 'etc' set into those files which
167already exist on your system.

173As with anything which modifies your disk's contents, this
174program can cause SIGNIFICANT data loss, and you are advised
175to make sure your data is backed up before beginning the
176installation process.
177
178Default answers are displayed in brackets after the questions.
179You can hit Control-C at any time to quit, but if you do so at a
180prompt, you may have to hit return.  Also, quitting in the middle of
181installation may leave your system in an inconsistent state.

189OK, then.  Enter 'halt' at the prompt to halt the machine.  Once the
