Installation is supported from several media types, including:
|
|
.(bullet
|
|
Tape
|

|
|
NFS
|
|
.It
|
|
CD-ROM
|
|
.It
|
|
FTP
|
|
.bullet)
|
|
Note that installing on a "bare" machine requires either a bootable
|
|
tape drive or an ethernet to a compatible NFS server. MVME147 may
|
|
also need to be booted over an RS232 connection.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
In order to create installation media, you will need all the files and
|
|
subdirectories in these two directories:
|
|
.Pp
|
|
.Dl Pa \&.../NetBSD-\*V/mvme68k/installation
|
|
.Dl Pa \&.../NetBSD-\*V/mvme68k/binary
|
|
.
|
|
.Ss2 Creating boot/install tapes
|
|
.
|
|
Installing from tape is the simplest method of all. This method uses two
|
|
tapes, one containing a bootable ramdisk and miniroot, the other containing
|
|
the installation sets.
|
|
.Pp
|
|
The boot tape is created as follows:
|
|
.Pp
|
|
.D1 Ic "cd .../NetBSD-\*V/mvme68k/installation
|
|
.D1 Ic "set T = /dev/nrst0
|
|
.D1 Ic "mt -f $T rewind
|
|
.D1 Ic "dd if=tapeimage/stboot of=$T
|
|
.D1 Ic "dd if=tapeimage/bootst of=$T obs=8k conv=osync
|
|
.D1 Ic "gzip -dc tapeimage/netbsd-rd.gz | dd of=$T obs=8k conv=osync
|
|
.D1 Ic "gzip -dc miniroot/miniroot.gz | dd of=$T obs=8k conv=osync
|
|
.D1 Ic "mt -f $T rewind
|
|
.Pp
|
|
The installation set tape is created as follows:
|
|
.Pp
|
|
.D1 Ic "cd .../NetBSD-\*V/mvme68k/binary/sets
|
|
.D1 Ic "set T = /dev/nrst0
|
|
.D1 Ic "mt -f $T rewind
|
|
.D1 Ic "foreach f (base etc comp games man misc text)
|
|
.D1 Ic "gzip -d \*< $f.tgz | dd of=$T bs=8k
|
|
.D1 Ic "end
|
|
.D1 Ic "mt -f $T rewind
|
|
.Pp
|
|
If the tape does not work as expected, you may need to explicitly
|
|
set the EOF mark at the end of each tape segment. Consult the
|
|
tape-related manual pages on the system where the tapes are created for
|
|
more details.
|
|

|
|
.Ss2 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
|
|
.Nx
|
|
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.
|
|
.Pp
|
|
If you are using a
|
|
.Nx
|
|
system as the boot-server, have a look at
|
|
the
|
|
.Xr 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).
|
|
.Pp
|
|
Booting an MVME147 from ethernet is not possible without first downloading
|
|
a small bootstrap program (sboot) via RS232. See the section entitiled
|
|
"Installing from NFS" for details on how to accomplish this.
|
|
.Pp
|
|
sboot expects to be able to download a second stage bootstrap
|
|
program via TFTP after having acquired its IP address through RARP
|
|
It will look for a filename derived from the machine's IP address
|
|
expressed in hexadecimal, with an extension of ".147". For example,
|
|
an MVME147 with IP address 130.115.144.11 will make an TFTP request for
|
|
`8273900B.147'. Normally, this file is just a symbolic link to the
|
|
.Nx*M
|
|
"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.
|
|
.Pp
|
|
The MVME167 boot ROM has code builtin to boot over ethernet from a
|
|
TFTP server. You should configure it to download the same "netboot"
|
|
program as is used for MVME147.
|
|
.Pp
|
|
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, although it might be a convenient place to put the uncompressed
|
|
miniroot image) and /etc/bootparams on the server should have an entry
|
|
for your client and its root directory. Note that you should rename the
|
|
netbsd-rd kernel to just 'netbsd' in the client's root directory before
|
|
trying to netboot the client.
|
|
.Pp
|
|
The client will need access to the miniroot image, which can be
|
|
provided using NFS or remote shell. If using NFS, miniroot.gz should be
|
|
expanded on the server, because doing so from the RAMDISK shell is not
|
|
so easy. The unzipped miniroot takes about 6 MB of space.
|
|
.Pp
|
|
If you will be installing
|
|
.Nx
|
|
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.
|
|
.
|
|
.Ss2 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 RAMDISK 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.
|
|
.
|
|
.Ss2 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.
|
|
.Pp
|
|
This method, of course, requires network access to an FTP server.
|
|
This might be a local system, or it might even be ftp.netbsd.org
|
|
itself. If you wish to use ftp.netbsd.org as your FTP file
|
|
server, you may want to keep the following information handy:
|
|
.Pp
|
|
.Dl No IP Address: ftp.netbsd.org
|
|
.Dl Login: Ic anonymous
|
|
.Dl Password: Ar your e-mail address
|
|
.Dl Server path: Ic /pub/NetBSD/NetBSD-\*V/mvme68k/binary
|
|
.(Note
|
|
If you're not using a nameserver duing installation,
|
|
you might find 204.152.184.75 handy; it's the IP address of
|
|
ftp.netbsd.org as of January, 1999.
