    111 you have entered the disklabel editor. Disk partition sizes and offsets
    112 are in sector (most likely 512 bytes) units. Make sure all partitions
    113 start on a cylinder boundary (c/t/s == XXX/0/0).

    150 This program is designed to help you put NetBSD on your disk,
    151 in a simple and rational way.  You'll be asked several questions,
    152 and it would probably be useful to have your disk's hardware
    153 manual, the installation notes, and a calculator handy.

    161 This program is designed to help you upgrade your NetBSD system in a
    162 simple and rational way.
    163 
    164 As a reminder, installing the 'etc' binary set is NOT recommended.
    165 Once the rest of your system has been upgraded, you should manually
    166 merge any changes to files in the 'etc' set into those files which
    167 already exist on your system.

    173 As with anything which modifies your disk's contents, this
    174 program can cause SIGNIFICANT data loss, and you are advised
    175 to make sure your data is backed up before beginning the
    176 installation process.
    177 
    178 Default answers are displayed in brackets after the questions.
    179 You can hit Control-C at any time to quit, but if you do so at a
    180 prompt, you may have to hit return.  Also, quitting in the middle of
    181 installation may leave your system in an inconsistent state.
