 160 Here is an example of what the partition information will look like once
 161 you have entered the disklabel editor. Disk partition sizes and offsets
 162 are in sector (most likely 512 bytes) units. Make sure these size/offset
 163 pairs are on cylinder boundaries (the number of sector per cylinder is
 164 given in the `sectors/cylinder' entry, which is not shown here).
 165
 166 Do not change any parameters except the partition layout and the label name.
 167 It's probably also wisest not to touch the `8 partitions:' line, even
 168 in case you have defined less than eight partitions.
 169
 170 [Example]
 171 8 partitions:
 172 #        size   offset    fstype   [fsize bsize   cpg]
 173   a:    50176        0    4.2BSD     1024  8192    16   # (Cyl.    0 - 111)
 174   b:    64512    50176      swap                        # (Cyl.  112 - 255)
 175   c:   640192        0   unknown                        # (Cyl.    0 - 1428)
 176   d:   525504   114688    4.2BSD     1024  8192    16   # (Cyl.  256 - 1428)

 195 This program is designed to help you install NetBSD on your system in a simple
 196 and rational way.  You'll be asked several questions, and it would probably be
 197 useful to have your disk's hardware manual, the installation notes, and a
 198 calculator handy.
 199
 200 In particular, you will need to know some reasonably detailed information
 201 about your disk's geometry. The kernel will attempt to display geometry
 202 information for SCSI disks during boot, if possible. If you did not make it
 203 note of it before, you may wish to reboot and jot down your disk's geometry
 204 before proceeding.
 205
 206 As with anything which modifies your hard disk's contents, this program can
 207 cause SIGNIFICANT data loss, and you are advised to make sure your hard drive
 208 is backed up before beginning the installation process.
 209
 210 Default answers are displyed in brackets after the questions. You can hit
 211 Control-C at any time to quit, but if you do so at a prompt, you may have to
 212 hit return.  Also, quitting in the middle of installation may leave your
 213 system in an inconsistent state.

 220 OK, then.  Enter 'halt' at the prompt to halt the machine.  Once the
 221 machine has halted, power-cycle the system to load new boot code.

 230 installed system, enter halt at the command prompt.  Once the system has
 231 halted, power-cycle the machine in order to load new boot code.  Make sure
 232 you boot from the root disk.
