The NetBSD Operating System is a fully functional Open Source UNIX-like operating system derived from the University of California, Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2 sources. NetBSD runs on 57 different system architectures (ports) across 15 distinct CPU families, and is being ported to more. The NetBSD 6.0.1 release contains complete binary releases for many different system architectures. (A few ports are not fully supported at this time and are thus not part of the binary distribution. Please see the NetBSD web site at http://www.NetBSD.org/ for information on them.)
NetBSD is a completely integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code.
NetBSD is a creation of the members of the Internet community. Without the unique cooperation and coordination the net makes possible, it's likely that NetBSD wouldn't exist.
The complete list of changes can be found in the CHANGES-6.0.1: http://ftp.NetBSD.org/pub/NetBSD/NetBSD-6.0.1/CHANGES-6.0.1 file in the top level directory of the NetBSD 6.0.1 release tree. An abbreviated list is as follows:

The root directory of the NetBSD 6.0.1 release is organized as follows:
In addition to the files and directories listed above, there is one directory per architecture, for each of the architectures for which NetBSD 6.0.1 has a binary distribution.
The source distribution sets can be found in subdirectories of the
subdirectory of the distribution tree.
They contain the complete sources to the system.
The source distribution sets are as follows:
All the above source sets are located in the
subdirectory of the distribution tree.
The source sets are distributed as compressed tar files.
Except for the

all sets may be unpacked into
with the command:
# cd / ; tar -zxpf set_name.tgz
In each of the source distribution set directories, there are files which contain the checksums of the files in the directory:
The SHA512 digest is safer, but MD5 checksums are provided so that a wider range of operating systems can check the integrity of the release files.

groff(1), all related programs, and their manual pages.
NetBSD maintains its own set of sources for the X Window System in order to assure tight integration and compatibility. These sources are based on XFree86 4.5.0. Binary sets for the X Window System are distributed with NetBSD. The sets are:
The sun3 binary distribution sets are distributed as gzipped tar files
named with the extension
The instructions given for extracting the source sets work equally
well for the binary sets, but it is worth noting that if you use that
method, the filenames stored in the sets are relative and therefore
the files are extracted
below the current directory.
Therefore, if you want to extract the binaries into your system, i.e.
replace the system binaries with them, you have to run the
command from the root directory (
) of your system.
There is a collection of Sun3 and Sun3X kernels in the
subdirectory of the

Please note that these kernels are simply gzipped and are not tar archives.
NetBSD/sun3 6.0.1 runs on most Sun3 machines, including:
Note that NetBSD/sun3 includes support for `Sun3X' machines, which used to be supported with a separate NetBSD/sun3x distribution.
The minimal configuration requires 4 MB of RAM and about 100 MB of disk
To install the entire system requires much more disk space.
To run X or compile the system, more RAM is recommended.
Good performance requires 8 MB of RAM, or 16 MB when running the
X Window System.
A good rule of thumb is to have a swap partition twice the size of the
amount of RAM in your machine.
You will probably want to compile your own kernel, as
is large and bulky to accommodate all people.
Note that the sun3 installation procedure uses a miniroot image which is placed into the swap area of the disk. The swap partition must be at least as large as the miniroot image (10 MB).
If it's not on this list, there is no support for it in this release.
Installation is supported from several media types, including:
The procedure for transferring the distribution sets onto installation media depends on the type of media. Instructions for each type of media are given below.
In order to create installation media, you will need all the files in the directory
The boot tape is created as follows:
# cd .../NetBSD-6.0.1/sun3/installation/tapeimage
# sh MakeBootTape /dev/nrst0
The install tape is created as follows:
# cd .../NetBSD-6.0.1/sun3/installation/tapeimage
# sh MakeInstallTape /dev/nrst0
If the tapes do not work as expected, you may need to explicitly
set the EOF mark at the end of each tape segment.
It may also be necessary to use the

system as the boot-server, have a look at
manual page for guidelines on how to proceed with this.
If the server runs another operating system, consult the
documentation that came with it (i.e.

be located in a place where the
daemon can find it.
(Remember, many TFTP daemons run in a chroot'ed environment.)
The netboot program may be found in the install directory of this distribution.
The netboot program will query a bootparamd server to find the
NFS server address and path name for its root, and then load a
kernel from that location.
The server should have a copy of the netbsd-rd kernel in the root area
for your client (no other files are needed in the client root) and
on the server
should have an entry for your client and its root directory.
The client will need access to the miniroot image, which can be
provided using NFS or remote shell.
If you will be installing NetBSD on several clients, it may be useful to know that you can use a single NFS root for all the clients as long as they only use the netbsd-rd kernel. There will be no conflict between clients because the RAM-disk kernel will not use the NFS root. No swap file is needed; the RAM-disk kernel does not use that either.
.../install(which you get via FTP). Once you have booted netbsd-rd (the RAM-disk kernel) and loaded the miniroot, you can load any of the distribution sets over the net using FTP. The install program in the miniroot automates the work required to configure the network interface and transfer the files.
The preparations for this installation/upgrade method are easy; all
you make sure that there's some FTP site from which you can retrieve
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
you need to know the numeric IP address of the

Sun3 machines usually need little or no preparation before installing NetBSD, other than the usual, well advised precaution of backing up all data on any attached storage devices.
You will need to know the SCSI target ID of the drive on which you will install NetBSD.

It might be a good time to run the diagnostics on your Sun3.
First, attach a terminal to the
serial port, then set the
switch to the Diagnostic position, and power-on the machine.
The Diag. switch setting forces console interaction to occur on ttya.
Note that the 3/80 has a
diag switch you can set at
the PROM monitor prompt.
To turn on diag boot mode, do:
q 70b 12
To return to normal boot mode, do:
q 70b 6.
The console location (ttya, ttyb, or keyboard/display) is controlled
by address 0x1F in the EEPROM, which you can examine and change in
the PROM monitor by entering
followed by a numeric value (or
if you don't want to change it).

Installing NetBSD is a relatively complex process, but if you have this document in hand it should not be too difficult.
There are several ways to install NetBSD onto your disk. If your machine has a tape drive the easiest way is Installing from tape (details below). If your machine is on a network with a suitable NFS server, then Installing from NFS is the next best method. Otherwise, if you have another Sun machine running SunOS you can initialize the disk on that machine and then move the disk. (Installing from SunOS is not recommended.)
The first example will use the tape on SCSI target 4, where the
second will use SCSI target 5.
is the monitor prompt.
After the tape loads, you should see many lines of configuration messages, and then the following `welcome' screen:
Welcome to the NetBSD/sun3 RAMDISK root!
This environment is designed to do only three things: 1: Partition your disk (use the command: edlabel /dev/rsd0c) 2: Copy a miniroot image into the swap partition (/dev/rsd0b) 3: Reboot (using the swap partition, i.e. /dev/sd?b).
Note that the sun3 firmware cannot boot from a partition located more than 1 GB from the beginning of the disk, so the swap partition should be completely below the 1 GB boundary.
Copying the miniroot can be done several ways, allowing the source of the miniroot image to be on any of these: boot tape, NFS server, TFTP server, rsh server
The easiest is loading from tape, which is done as follows: mt -f /dev/nrst0 rewind mt -f /dev/nrst0 fsf 2 dd if=/dev/nrst0 of=/dev/rsd0b bs=32k conv=sync (For help with other methods, please see the install notes.)
To reboot using the swap partition, first use "halt", then at the PROM monitor prompt use a command like: b sd(,,1) -s
To view this message again, type: cat /.welcome
Copy the miniroot as described in the welcome message, and reboot from that just installed miniroot. See the section entitled Booting the miniroot for details.
First, at the Sun PROM monitor prompt, enter a boot command using the network interface as the boot device. On desktop machines this is le, and ie on the others. Examples:
>b le() -s
>b ie() -s
After the boot program loads the RAMDISK kernel, you should see the welcome screen as shown in the Installing from tape section above. You must configure the network interface before you can use any network resources. For example the command:
ssh> ifconfig le0 inet 184.108.40.206 up
will bring up the network interface with that address. The next step is to copy the miniroot from your server. This can be done using either NFS or remote shell. (In the examples that follow, the server has IP address 220.127.116.11.) You may then need to add a default route if the server is on a different subnet:
ssh> route add default 18.104.22.168 1
You can look at the route table using:
ssh> route show
Now mount the NFS file system containing the miniroot image:
ssh> mount -r 22.214.171.124:/server/path /mnt
The procedure is simpler if you have space for an expanded (not compressed) copy of the miniroot image. In that case:
ssh> dd if=/mnt/miniroot.fs of=/dev/rsd0b bs=8k
Otherwise, you will need to use
to expand the miniroot image while copying.
This is tricky because the
(small shell) does not handle
Instead, you first run the reader in the background with its input set
and then run the other program in the foreground with its output to
The result looks like this:
ssh> run -bg dd if=/dev/pipe of=/dev/rsd0b obs=8k
ssh> run -o /dev/pipe zcat /mnt/install/miniroot.fs.gz
To load the miniroot using rsh to the server, you would use a pair of commands similar to the above. Here is another example:
ssh> run -b dd if=/dev/pipe of=/dev/rsd0b obs=8k
ssh> run -o /dev/pipe rsh 126.96.36.199 zcat miniroot.fs.gz
First, boot SunOS and place the miniroot file onto the hard drive. If you do not have gzip for SunOS, you will need to decompress the image elsewhere before you can use it.
Next, bring SunOS down to single user mode to insure that nothing will be using the swap space on your drive. To be extra safe, reboot the machine into single-user mode rather than using the shutdown command.
Now copy the miniroot image onto your swap device (here
with the command
gzip -dc miniroot.fs.gz | dd of=/dev/rsd0b obs=32k
or if you have already decompressed the miniroot
dd if=miniroot.fs of=/dev/rsd0b obs=32k
Finally, reboot the machine and instruct the ROM to boot from the swap device as described in the next section.
b' of the disk with SCSI target ID=0 then the PROM boot command would be:
>b sd(0,0,1) -s
With SCSI target ID=2, the PROM is:
>b sd(0,10,1) -s
The numbers in parentheses above are:
The miniroot's install program will:
foo.bar.org. If, during the process of configuring the network interfaces, you make a mistake, you will be able to re-configure that interface by simply selecting it for configuration again.
First-time installation on a system through a method other than the
installation program is possible, but strongly discouraged.
Once you've got the operating system running, there are a few things you need to do in order to bring the system into a properly configured state. The most important steps are described below.

If you wish to install any of the software freely available for UNIX-like systems you are strongly advised to first check the NetBSD package system, pkgsrc. pkgsrc automatically handles any changes necessary to make the software run on NetBSD.

pkgin(1)in the sysinst post-installation configuration menu, you can use it to automatically install binary packages over the network. Assuming that
/usr/pkg/etc/pkgin/repositories.confis correctly configured, you can install them with the following commands:
# pkgin install tcsh # pkgin install bash # pkgin install perl # pkgin install apache # pkgin install kde # pkgin install firefox ...
The above commands will install the Tenex-csh and Bourne Again shells, the Perl programming language, Apache web server, KDE desktop environment and the Firefox web browser as well as all the packages they depend on.
pkgsrc(7)framework for compiling packages can be obtained by retrieving the file ftp://ftp.NetBSD.org/pub/pkgsrc/pkgsrc.tar.gz. It is typically extracted into
/usr/pkgsrc(though other locations work fine) with the commands:
# cd /usr
# tar -zxpf pkgsrc.tar.gz
After extracting, see the

It is possible to easily upgrade your existing NetBSD/sun3 system using the upgrade program in the miniroot. If you wish to upgrade your system by this method, simply select the upgrade option once the miniroot has booted. The upgrade program with then guide you through the procedure. The upgrade program will:
Using the miniroot's upgrade program is the preferred method of upgrading your system.
