You now have to prepare your root disk for the installation of NetBSD. This
is further referred to as 'labeling' a disk.

First you get the chance to edit or create an AHDI compatible partitioning on
the installation disk. Note that NetBSD can do without AHDI partitions,
check the documentation.
If you want to use an AHDI compatible partitioning, you have to assign some
partitions to NetBSD before NetBSD is able to use the disk. Change the 'id'
of all partitions you want to use for NetBSD filesystems to 'NBD'. Change
the 'id' of the partition you wish to use for swap to 'SWP'.

	# display example
	cat << \__md_prep_disklabel_3
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.

[Example]
partition      start         (c/t/s)      nblks         (c/t/s)  type

 a (root)          0       (0/00/00)      31392     (109/00/00)  4.2BSD
 b (swap)      31392     (109/00/00)      73440     (255/00/00)  swap
 c (disk)          0       (0/00/00)    1070496    (3717/00/00)  unused
 d (user)     104832     (364/00/00)      30528     (106/00/00)  4.2BSD
 e (user)     135360     (470/00/00)      40896     (142/00/00)  4.2BSD
 f (user)     176256     (612/00/00)      92160     (320/00/00)  4.2BSD
 g (user)     268416     (932/00/00)     802080    (2785/00/00)  4.2BSD

This program is designed to partition your disk in preparation of the
NetBSD installation. At this stage, the only thing you _must_ setup
is a swap partition. If you wish, the remaining partitioning work might
be delayed until the actual installation.

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

md_not_going_to_install() {
	cat << \__not_going_to_install_1

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.

Note: If you wish to have another try. Just type '^D' at the prompt. After
      a moment, the program will restart itself.

__not_going_to_install_1
}

md_congrats() {
	cat << __congratulations_1

CONGRATULATIONS!  You have successfully partitioned your disks!
Now you can use file2swap.ttp to transfer the install.fs to your
swap partition and continue the installation.
Enter halt at the command prompt. Once the system has halted, reset the
machine and re-boot it.

Note: If you wish to have another try. Just type '^D' at the prompt. After
      a moment, the installer will restart itself.
