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'.

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

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. __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.

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.
