Installation is supported from several media types, including:
|
|
.Bl -bullet -compact -offset indent
|
|
.It
|
|
Tape
|
|
.It
|
|
NFS
|
|
.It
|
|
Floppy
|
|
.It
|
|
FTP
|
|
.El
|
|
.(Note
|
|
Installing on a "bare" machine requires some bootable
|
|
device; either a tape or floppy drive or a NFS server together
|
|
with a machine that can act as a MOP loader.
|
|
NetBSD/vax can use both BOOTP/DHCP and
|
|
BOOTPARAMS for netboot installations.
|
|
.Note)
|
|
.Pp
|
|
The procedure for transferring the distribution sets onto
|
|
installation media depends on the type of media. most of it is up to
|
|
you, depending what you want to install, but preferred are to do
|
|
the installation over network as soon as the miniroot is installed.
|
|
.
|
|
.Ss2 Creating boot tapes
|
|
.
|
|
Fetch the bootable miniroot image from
|
|
.Dl \&.../NetBSD-\*V/vax/miniroot/miniroot.gz Ns Ar {50,33}
|
|
Gunzip the miniroot and write it on the beginning of the tape.
|
|
Under Ultrix this is done like this:
|
|
.D1 Ic "gunzip miniroot.gz
|
|
.D1 Ic "mt -f /dev/rmt0h rewind
|
|
.D1 Ic "dd if=miniroot of=/dev/rmt0h
|
|
.D1 Ic "mt -f /dev/rmt0h rewoffl
|
|
.Pp
|
|
Under NetBSD this is done the same way, except for the tape name:
|
|
.D1 Ic "gunzip miniroot.gz
|
|
.D1 Ic "mt -f /dev/rmt8 rewind
|
|
.D1 Ic "dd if=miniroot of=/dev/rmt8
|
|
.D1 Ic "mt -f /dev/rmt8 rewoffl
|
|
.Pp
|
|
Of course, if you have a tape unit other than unit 0 you have to use
|
|
the corresponding unit number.
|
|
.Pp
|
|
If you are using any other OS to create bootable tapes, remember that
|
|
the blocksize
|
|
.Em must
|
|
be 512 for the file to be bootable! Otherwise it just won't work.
|
|
.
|
|
.Ss2 Creating boot floppies
|
|
.
|
|
Fetch the bootable miniroot image from
|
|
.Dl \&.../NetBSD-\*V/vax/miniroot/miniroot.gz Ns Ar {50,33}
|
|
and gunzip it. It is a 1.2MB bootable image that will boot from any
|
|
floppy of size 1.2MB and bigger.
|
|
Note that you
|
|
.Em cannot
|
|
install from RX50 floppies due to the small size. This may change
|
|
in the future.
|
|
.Pp
|
|
All floppies except RX50 uses a standardized format for storing data
|
|
so writing the miniroot to the floppy can be done on any PC. From DOS
|
|
the preferred way to do this is using RAWRITE.EXE.
|
|
.
|
|
.Ss2 Booting from NFS server
|
|
.
|
|
All VAXen that can boot over network uses MOP, a DEC protocol.
|
|
To be able to use MOP, a MOP daemon must be present on one of
|
|
the machines on the local network. The boot principle is:
|
|
.Bl -bullet -compact -offset indent
|
|
.It
|
|
The VAX broadcast a wish to load an image.
|
|
.It
|
|
A mopd answers and send the boot program to the VAX.
|
|
.It
|
|
The boot program does rarp/bootp requests, mounts the root filesystem
|
|
and loads the kernel.
|
|
.It
|
|
The kernel is loaded and starts executing.
|
|
.El
|
|
.Pp
|
|
If your machine has a disk and network connection, 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.
|
|
.Pp
|
|
If you are using a NetBSD 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
|
|
You also must install a MOP loader. If you are booting from another
|
|
NetBSD machine, MOP are included in the distribution, otherwise you
|
|
may have to install a MOP loader. A loader can be found at
|
|
.Lk ftp.stacken.kth.se:/pub/OS/NetBSD/mopd
|
|
Fetch the latest and read the
|
|
installation instructions.
|
|
.Pp
|
|
The file that should be loaded is called boot.mop and is located in
|
|
.Dl \&.../NetBSD-\*V/vax/installation/netboot/boot.mop Ns Ar {50,33}
|
|
.Pp
|
|
The kernel to load is the same kernel as the miniroot uses and can
|
|
be found in
|
|
.Dl \&.../NetBSD-\*V/vax/installation/netboot/netbsd.gz Ns Ar {50,33}
|
|
From the install program started in the kernel the rest of the system
|
|
can be installed.
|
|
There is also a very good FAQ for netbooting VAXen at
|
|
.Lk http://world.std.com/~bdc/projects/vaxen/VAX-netboot-HOWTO.html
|
|
that describes netbooting of VAXen from many different OS'es.
