Installation is supported from several media types, including:
NFS partitions
FTP
Tape
The steps necessary to prepare the distribution sets
for installation depend on which method of installation
you choose. The various methods are explained below.
To prepare for installing via an NFS partition:
Place the OpenBSD software you wish to install into
a directory on an NFS server, and make that directory
mountable by the machine which you will be installing
OpenBSD on. This will probably require modifying the
/etc/exports file of the NFS server and resetting
mountd, acts which will require superuser privileges.
Note the numeric IP address of the NFS server and of
the router closest to the the new OpenBSD machine,
if the NFS server is not on a network which is
directly attached to the OpenBSD machine.
If you are using a diskless setup to install OpenBSD on
your machine, you can take advantage of the fact that
the above has already been done on your machine's server.
So, you can conveniently put the OpenBSD filesets in your
machine's root filesystem on the server where the install
program can find them.
Once you have done this, you can proceed to the next
step in the installation process, preparing your
system for OpenBSD installation.
To prepare for installing via FTP:
NOTE: this method of installation is recommended
only for those already familiar with using
the BSD network-manipulation commands and
interfaces. If you aren't, this documentation
should help, but is not intended to be
all-encompassing.
The preparations for this method of installation
are easy: all you have to do is make sure that
there's some FTP site from which you can retrieve
the OpenBSD installation when it's time to do
the install. You should know the numeric IP
address of that site, the numeric IP address of
your nearest router if one is necessary
Once you have done this, you can proceed to the next
step in the installation process, preparing your
system for OpenBSD installation.
To prepare for installing via a tape:
To install OpenBSD from a tape, you need to somehow
make a boot tape on the appropriate kind of tape.
The files needed for this are:
stboot - The Motorola VID block
bootst - The bootstrap program
bsd.rd.gz - The ramdisk installation kernel
If you're making the tape on a UN*X system, the easiest
way to do so is:
dd obs=512 if=stboot of=<no-rewind tape_device>
dd obs=512 if=bootst of=<no-rewind tape_device>
dd conv=sync obs=512 if=bsd.rd.gz of=<no-rewind tape_device>
where "<no-rewind tape_device>" is the name of the tape device
that describes the tape drive you're using (possibly
something like /dev/nrst0, but we make no guarantees 8-).
Now you need to get the OpenBSD filesets you wish to
install on your system on to the appropriate kind of tape,
in tar format.
If you're making the tape on a UN*X system, the easiest
way to do so is:
tar cvf <tape_device> <files>
where "<tape_device>" is the name of the tape device
that describes the tape drive you're using (possibly
something like /dev/nrst0, but again, we make no guarantees 8-).
Under SunOS 5.x, this would be something like /dev/rmt/0mbn.
Again, your mileage may vary. If you can't figure it out,
ask your system administrator. "<files>" are the names
of the "set_name.nnn" files which you want to be placed
on the tape.
Once you have done this, you can proceed to the next
step in the installation process, preparing your
system for OpenBSD installation.
