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 all partitions start on a cylinder boundary (c/t/s == XXX/0/0).

[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

md_welcome_banner() { if [ "$MODE" = "install" ]; then echo "" echo "Welcome to the NetBSD/sun2 ${VERSION} installation program." cat << __welcome_banner_1

This program is designed to help you put NetBSD on your disk, 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. __welcome_banner_1

else
	echo ""
	echo "Welcome to the NetBSD/sun2 ${VERSION} upgrade program."
	cat << \__welcome_banner_2

This program is designed to help you upgrade your NetBSD system in a simple and rational way.

As a reminder, installing the etc' binary set is NOT recommended. Once the rest of your system has been upgraded, you should manually merge any changes to files in the etc' set into those files which already exist on your system. __welcome_banner_2 fi

cat << __welcome_banner_3

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 installation 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. Also, quitting in the middle of installation may leave your system in an inconsistent state.

__welcome_banner_3 }

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.

__not_going_to_install_1 }

md_congrats() { local what; if [ "$MODE" = "install" ]; then what="installed"; else what="upgraded"; fi cat << __congratulations_1

CONGRATULATIONS! You have successfully $what NetBSD! To boot the installed system, enter halt at the command prompt. Once the system has halted, reset the machine and boot from the disk.
