If you are not booting off a CD-ROM, you will need to have some floppy
disks to boot off;
either two 1.44 MB floppies or one 1.2 MB floppy.
.Pp
For laptops that have cardbus slots, you should use the
.Pa bootlap1.fs
and
.Pa bootlap2.fs
floppy images.
.Pp
For older machines with little RAM, use
.Pa boot-tiny.fs .
This image is tailored towards old, small-memory systems, and thus does
not contain any PCI or SCSI support. It should work on systems with
4M of RAM. Note that this means 4M available to NetBSD; systems that
are said to have 4M may have 640k of base memory and 3072k of extended
memory, which currently will not work, as this is a total of 3712k.
.Pp
For old machines that may have EISA, SCSI and more RAM, but only
have an 1.2M floppy drive, use
.Pa boot-small.fs .
For all other systems, use
.Pa boot1.fs
and
.Pa boot2.fs
.
.Pp
For the 2-floppy sets (and the CD boot image), utilities to repair
a badly crashed systems are included. The -small and -tiny images
have seperate rescue floppy images because of lack of space.
.Pp
If you are using a
.Ul
system to write the floppy images to
disks, you should use the
.Xr dd
command to copy the file system image(s)
(.fs file) directly to the raw floppy disk.
It is suggested that you read the
.Xr dd 1
manual page or ask your system administrator to determine the correct
set of arguments to use; it will be slightly different from system to
system, and a comprehensive list of the possibilities is beyond the
scope of this document.
.Pp
If you are using
.Tn MS-DOS
to write the floppy image(s) to floppy disk, you should use the
.Ic rawrite
utility, provided in the
.Pa i386/utilities
directory of the
.Nx
distribution.
It will write a file system image (.fs file) to a floppy disk.
A

You will need to have a 1.44 MB floppy disk to boot off.
You must put the boot floppy image onto this disk, which contains
software to install
.Nx
system.
.Pp
If you are using a
.Ul
system (such as
.Tn NEWS-OS
or other
.Nx
machines) to write the floppy images to disks, you should use the

If you have an i386 machine which runs
.Tn MS-DOS

you can use the
.Ic rawrite

.Pa i386/installation/misc
directory of the

distribution.
It will write a file system image (.fs file) to a floppy disk. 
A
.Ic rawrite32
is also available that runs under
.Tn MS Windows .
.Pp
Though
.Nx*M
uses the floppy disk to boot for the initial
installation, the
.Nx*M
kernel does not support the
floppy device.
Some other machines or systems are still required to write floppy images
even after
.Nx*M
has been installed.
.Pp
SCSI devices on NWS-12x0 machines are not supported (yet), so they
can only run
.Nx*M
diskless.
No file transfer is needed, and all you have to do is to prepare files on
the server.
More information about diskless setting can be found at
.Lk http://www.netbsd.org/Documentation/network/netboot/
.Pp
The
.Tn NEWS
PROM also supports tape boot and network boot, but
.Nx*M
does not support them currently.

After the boot floppy is prepared, just type
.Ic "bo fh"
on the PROM prompt to boot it.

First-time installation on a bare machine is not supported, because most
DECstations do not have any suitable load device.

.Tn MOP .
.Pp
The only DECstation with a floppy-disk drive is the Personal DECstation,
and that device is not supported as a boot device.
.Pp
The recommended installation procedure is to boot an install kernel
via

disk to the target installation system, and then boot the miniroot.

When you chose the first method, you have to put the installation kernel
.Pa netbsd
and the
.Pa loadbsd.x
utility to a disk accessible from Human68k.  These files can be found in
.Pa installation/misc
directory of the
.Nx
distribution.

To invoke the installation system, just type
.Pp
.Dl Ic "loadbsd.x netbsd"

command line.
.Pp
When you chose the second method, you have to make the boot floppy
from the floppy image
.Pa sysinst.fs .
The image file can be found in
.Pa installation/floppy
directory of the
.Nx
distribution.
.Pp
If you are using a
.Ul
system to write the floppy image to
disks, you should use the
.Pa dd
command to copy the file system images (.fs files) directly to the raw
floppy disks. It is suggested that you read the
.Xr dd 1
manual page or
ask your system administrator to determine the correct set of
arguments to use; it will be slightly different from system to system,
and a comprehensive list of the possibilities is beyond the scope of
this document.
.Pp
If you are using
.Tn Human68k
to write the floppy images to disks, you should use the
.Ic rawrite
utility, provided in the
.Pa installation/misc
directory of the
.Nx
distribution. It will write the file system
images (.fs files) to disks.
.Pp
To use the boot floppy, insert the floppy to your floppy drive 0,
and reboot your computer with OPT.1 key pressed.
.Pp
If you have less than 5MB of memory, you have to use the
`floppy-root' installation system instead of the above
`ramdisk-root' installation system.  `Floppy-root' installation
system is composed of two floppies, `kern' and `inst'.  They are
made from the floppy images
.Pa kern.fs 
and
.Pa inst.fs
respectively, both of which are found in
.Pa installation/floppy
directory of the
.Nx
distribution.  See above how to write the images to floppies.
.Pp
To start the `floppy-root' installation system, insert the `kern' floppy
to your floppy drive 0, and reboot your computer with OPT.1 key pressed.
When you are prompted that `Insert filesystem floppy and press return.',
replace the `kern' floppy with `inst' floppy and press return key.
.Pp
Once booted, the `floppy-root' installation system is identical with
the `ramdisk-root' installation system, except that the former constantly
accesses the floppy disk.  Floppy disks are relatively unreliable
media and cause some warning messages to report access errors, most of
which are corrected and can be ignored.  With the latter installation
system the floppy disk is not used once the system has booted off and can
be removed from the drive.

If you booted from a floppy, the floppy disk may be removed from
the drive after the system has booted.

All of the

The preparations for this installation/upgrade method are
easy; all you need to do is make sure that there's an FTP
site from which you can retrieve the
.Nx
distribution when you're about to
install or upgrade.
You need to know the numeric IP address of that site, and,
if it's not on a network directly connected to the machine
on which you're installing or upgrading
.Nx ,
you need to know the numeric IP address of the router closest
to the
.Nx
machine.
Finally, you need to know the numeric IP address of the
.Nx
machine itself.
If you don't have access to a functioning nameserver during
installation, the IP address of
.Sy ftp.netbsd.org
is
.Li 204.152.184.75
(as of April, 2001).

Once you have this information, you can proceed to the next
step in the installation or upgrade process.

Place the

distribution sets you wish to install into a
directory on an NFS server, and make that directory mountable
by the machine on which you are installing or upgrading

This will probably require modifying the
.Pa /etc/exports
file on of the NFS server and resetting its mount daemon (mountd).
(Both of these actions will probably require superuser
privileges on the server.)

where
.Ar tape_device
is the name of the tape device that
describes the tape drive you're using; possibly

(If you can't figure it out, ask your system administrator.)
In the above example,
.Ar dist_directories
are the
distribution sets' directories, for the distribution sets you
wish to place on the tape.
For instance, to put the
.Sy misc, base, No and Sy etc
distributions on tape (in
order to do the absolute minimum installation to a new disk),
you would do the following:
.Pp
.Dl # Ic "cd \&.../NetBSD-\*V"
.Dl # Ic "cd \*M/binary"
.Dl # Ic "tar -cf" Ar tape_device Ic "misc etc kern"
