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) [End of example]

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. __welcome_banner_1 }
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.

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.
