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

and it would probably be useful to have your disk's hardware

manual, the installation notes, and a calculator handy.

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.

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.

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 installer will restart itself.
