Here is an example of what the partition information will look like once
you have entered the disklabel editor. Disk partition sizes and offsets
are in sector (most likely 512 bytes) units. Make sure these size/offset
pairs are on cylinder boundaries (the number of sector per cylinder is
given in the `sectors/cylinder' entry, which is not shown here).

Do not change any parameters except the partition layout and the label name.
It's probably also wisest not to touch the `8 partitions:' line, even
in case you have defined less than eight partitions.

[Example]
8 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:    50176        0    4.2BSD     1024  8192    16   # (Cyl.    0 - 111)
  b:    64512    50176      swap                        # (Cyl.  112 - 255)
  c:   640192        0   unknown                        # (Cyl.    0 - 1428)
  d:   525504   114688    4.2BSD     1024  8192    16   # (Cyl.  256 - 1428)

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

In particular, you will need to know some reasonably detailed information
about your disk's geometry. The kernel will attempt to display geometry
information for SCSI disks during boot, if possible. If you did not make it
note of it before, you may wish to reboot and jot down your disk's geometry
before proceeding.

As with anything which modifies your hard disk's contents, this program can
cause SIGNIFICANT data loss, and you are advised to make sure your hard drive
is backed up before beginning the installation process.

Default answers are displyed 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.

md_not_going_to_install() {

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

__not_going_to_install_1
}

md_congrats() {
	cat << \__congratulations_1

CONGRATULATIONS!  You have successfully installed NetBSD!  To boot the
installed system, enter halt at the command prompt.  Once the system has
halted, power-cycle the machine in order to load new boot code.  Make sure
you boot from the root disk.
