Installation is supported from several media types, including:
|
|
* Tape
|
|
* NFS
|
|
* CD-ROM
|
|
* FTP
|
|
|
|
Note that installing on a "bare" machine requires some bootable
|
|
device; either a tape drive or Sun-compatible NFS server.
|
|
|
|
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
|
|
.../NetBSD-_VER/sun3x/
|
|
|
|
* Creating boot/install tapes:
|
|
|
|
Installing from tape is the simplest method of all.
|
|
This method uses two tapes; one called the "boot"
|
|
tape, and another called the "install" tape.
|
|
|
|
The boot tape is created as follows:
|
|
|
|
cd .../NetBSD-_VER/sun3x/installation/tapeimage
|
|
sh MakeBootTape /dev/nrst0
|
|
|
|
The install tape is created as follows:
|
|
|
|
cd .../NetBSD-_VER/sun3x/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 `conv=osync' argument to dd(1). Note that
|
|
this argument is incompatible with the `bs=' argument. Consult
|
|
the tape-related manual pages on the system where the tapes are
|
|
created for more details.
|
|
|
|
* Boot/Install from NFS server:
|
|
|
|
If your machine has a disk and network connection, but no tape drive,
|
|
it may be convenient for you to install NetBSD over the network. This
|
|
involves temporarily booting your machine over NFS, just long enough
|
|
so you can initialize its disk. This method requires that you have
|
|
access to an NFS server on your network so you can configure it to
|
|
support diskless boot for your machine. Configuring the NFS server
|
|
is normally a task for a system administrator, and is not trivial.
|
|
|
|
If you are using a NetBSD system as the boot-server, have a look at
|
|
the diskless(8) 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. add_client(8) on SunOS).
|
|
|
|
Your Sun3x expects to be able to download a second stage bootstrap
|
|
program via TFTP after having acquired its IP address through RARP
|
|
when instructed to boot "over the net". It will look for a filename
|
|
derived from the machine's IP address expressed in hexadecimal. For
|
|
example, a sun3x which has been assigned IP address 130.115.144.11
|
|
will make an TFTP request for `8273900B'. Normally, this file is a
|
|
symbolic link to the NetBSD/sun3x "netboot" program, which should be
|
|
located in a place where the TFTP 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 /etc/bootparams 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 using NFS, miniroot.gz
|
|
must be expanded on the server, because there is no gzip program
|
|
in the RAMDISK image. The unzipped miniroot takes 8MB of space.
|
|
|
|
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/Upgrade from CD-ROM:
|
|
|
|
This method requires that you boot from another device (i.e. tape
|
|
or network, as described above). You may need to make a boot tape
|
|
on another machine using the files provided on the CD-ROM. Once
|
|
you have booted netbsd-rd (the RAM-disk kernel) and loaded the
|
|
miniroot, you can load any of the distribution sets directly from
|
|
the CD-ROM. The "install" program in the miniroot automates the
|
|
work required to mount the CD-ROM and extract the files.
|
|
|
|
* Install/Upgrade via FTP:
|
|
|
|
This method requires that you boot from another device (i.e. tape
|
|
or network, as described above). You may need to make a boot tape
|
|
on another machine using the files in .../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
|
|
the NetBSD 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 NetBSD, you need to know the numeric IP address of the
|
|
router closest to the NetBSD machine. Finally, you need to know the
|
|
numeric IP address of the NetBSD machine itself.
