Installing
.Nx
is a relatively complex process, but if you have
this document in hand it should not be too difficult.
.Pp
There are several ways to install
.Nx
onto your disk. If your
machine has a tape drive the easiest way is
.Sx "Installing from tape"
(details below). If your machine is on a network with a suitable
NFS server, then
.Sx "Installing from NFS"
is the next best method.
Otherwise, if you have another \*M machine running
.Nx
you can
initialize the disk on that machine and then move the disk.
.
.Ss2 Installing from tape
.
Create the
.Nx*M
\*V boot tape as described in the section
entitled
.Sx "Preparing a boot tape" .
Then, with the tape in the drive, type the following at the Bug prompt:
.Pp
.Dl 147-Bug\*> Ic "bo 5"
.Pp
.Dl 16x-Bug\*> Ic "bo 0,50"
.Pp
As mentioned earlier, this assumes your tape is jumpered for SCSI-ID 5.
.Pp
As the tape loads (which may take 20 to 30 seconds), you will see a
series of status messages. It may be useful if you can capture these
messages to a file, or a scrollable xterm window. In particular, you
should make a note of the lines which describe the geometry of the
SCSI disks detected by
.Nx .
They are of the form:
.(disp
sd0 at scsibus0 targ 0 lun 0: \*<Maker, Disk, Foo\*> SCSI1 0/direct fixed
sd0: 800 MB, 800 cyl, 16 head, 128 sec, 512 bytes/sect x 1638400 sectors
.disp)
.Pp
The information of most interest is the number of sectors; for the ficticious
disk above, it's 1638400. You will need this number when you come to create
a disklabel for that drive.
.Pp
Here is an example of an MVME147 system booting from tape:
.(disp

Finally, you will see the following "welcome" message:
.(disp
Welcome to the NetBSD/\*M RAMDISK root!
This environment is designed to do only four things:
1: Partititon your disk (use the command: edlabel /dev/rsd0c)
2: Copy a miniroot image into the swap partition (/dev/rsd0b)
3: Make that partition bootable (using 'installboot')
4: Reboot (using the swap partition, i.e. /dev/sd0b).
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 3
dd bs=8k if=/dev/nrst0 of=/dev/rsd0b
(For help with other methods, please see the install notes.)
To reboot using the swap partition after running installboot, first
use
.Ic halt ,
then at the Bug monitor prompt use a command like:
1x7Bug> bo 0,,b:
To view this message again, type: cat /.welcome
ssh:
.disp)
.Pp
You must now create a disklabel on the disk you wish to use for the
root file system
.Pq Pa / .
This will usually be
.Li sd0 .
The disklabel is used by
NetBSD to identify the starting block and size of each partition on
the disk.
.Pp
Partitions are named
.Li sd0a ,
.Li sd0b ,
.Li sd0c ,
etc,
up to
.Li sd0h .
The \*M port of
.Nx
makes some assumptions about the first three partitions on a boot disk:
.Pp
.(tag sd0c -compact
.It Li sd0a
The root file system
.Pq Pa / .
.It Li sd0b
The swap partition.
.It Li sd0c
The whole disk. Also known as the
.Em raw partition .
.tag)
.Pp
The
.Em raw partition No is special;
.Nx
is able to use it even if the
disk has no label. You should never create a file system on the Raw
Partition, even on a non-boot disk.
.Pp
It is good practice to put
.Pa /usr
on a different partition than
.Pa /
(root, AKA
.Li sd0a ) .
So, the first available partition for
.Pa /usr
is
.Li sd0d .
Refer to the section entitled
.Sx NetBSD System Requirements and Supported Devices
for information on the recommended sizes of the
.Pa /
(root),
.Pa /usr
and swap partitions.
.Pp
You are not required to define any partitions beyond
.Li sd0d ,
but if you
have a large disk drive, you might want to create several other partitions
for file systems such as
.Pa /home
or
.Pa /usr/src .
Note that at this time you
are only required to partition the root/boot disk; you will get the
opportunity to partition any other disks in your system from the main
.Ic miniroot
installation program.
.Pp
To create the disklabel and partitions, use the
.Li edlabel
program, passing it the name of the Raw Partition of your root/boot disk.
.Pp
.Dl ssh: Ic "edlabel /dev/rsd0c"
.Dl edlabel menu:
.Dl print - display the current disk label
.Dl modify - prompt for changes to the label
.Dl write - write the new label to disk
.Dl quit - terminate program
.Dl edlabel\*>
.Pp
The program shows what commands it recognizes;
.Ic print ,
.Ic modify ,
.Ic write ,
and
.Ic quit .
It will accept the first letter of a command if
you don't feel like typing each one in full.
.Pp
To start creating the basic partitions, you should enter
.Ic m No (modify)
at the edlabel prompt, then enter the letter corresponding to the first
.No partition, Sy a .
.Pp
.Dl edlabel\*> Ic m
.Pp
.Dl modify subcommands:
.Dl @ : modify disk parameters
.Dl a-h : modify partition
.Dl s : standarize geometry
.Dl q : quit this subcommand
.Dl edlabel/modify\*> Ic a
.Dl a (root) 0 (0/00/00) 0 (0/00/00) unused
.Dl start as \*<blkno\*> or \*<cyls/trks/sects\*> : Ic 0
.Dl length as \*<nblks\*> or \*<cyls/trks/sects\*> : Ic 65536
.Dl type: Ic 4.2BSD
.Dl edlabel/modify\*>
.Pp
When you enter the start and length of a partition, you can use either
blocks or cylinder/track/sector notation. If this is the first time
you've partitioned a disk for
.Nx ,
it's probably easiest to use block
notation. The above example creates partition
.Sq Li a ,
starting at block zero
and with a size of 65536 blocks. Note that the usual size of a block is
512 bytes, so this creates a 32 MB partition.
.Pp
The
.Li type
of the partition should be
.Li 4.2BSD ,
otherwise you won't be able to create a file system on it.
.Pp
Next, create a swap partition (b). Note that the minimum size of this
swap partition should be 8 MB, otherwise you won't be able to use a
miniroot to complete the
.Nx
installation!
.Pp
.Dl edlabel/modify\*> Ic b
.Dl b (swap) 0 (0/00/00) 0 (0/00/00) unused
.Dl start as \*<blkno\*> or \*<cyls/trks/sects\*> : Ic 65536
.Dl length as \*<nblks\*> or \*<cyls/trks/sects\*> : Ic 32768
.Dl type: Ic swap
.Dl edlabel/modify\*>
.Pp
Here, we specify a value for
.Li start
such that the swap partition follows immediately after partition
.Sq Li a ,
i.e. 65536. The length of the swap
partition should be a multiple of the amount of RAM you have in your
system. Here, we've chosen 32768, or 16 MB. The next available block on the
drive is thus 65536 + 32768. We will use this to create partition
.Sq Li d
for our
.Pa /usr
file system. (Note that for a busy system, or a system with more
than 8 MB of RAM, you'll be better off with a 32 or 64 MB swap partition.)
.Pp
.Dl edlabel/modify\*> Ic d
.Dl d (user) 0 (0/00/00) 0 (0/00/00) unused
.Dl start as \*<blkno\*> or \*<cyls/trks/sects\*> : Ic 98304
.Dl length as \*<nblks\*> or \*<cyls/trks/sects\*> : Ic 1540096
.Dl type: Ic 4.2BSD
.Dl edlabel/modify\*> Ic q
.Dl edlabel\*>
.Pp
As you can see, we've chosen to assign the remainder of the disk to
.Pa /usr .
Since there are 1638400 sectors on the example disk (did you remember to
note down the number of sectors on your disk during boot?), and partition
.Sy d
starts at sector 98304, a simple bit of arithmetic (1638400 - 98304)
gives
.Sy d No a size of 1540096.
.Pp
Note that the above partition sizes are just guidelines. If your disk is
large enough, you should resize the partitions appropriately and
perhaps also create a /var partition as well.
.Pp
You now need to write this new disklabel, together with the partition
details you've just entered, to disk. You might also try the
.Sq Ic p
command
to view the partitions. Once written, you can quit back to ssh using
.Sq Ic q .
.Pp
.Dl edlabel\*> Ic p

.disp)
.Pp
.Dl edlabel\*> Ic w
.Dl edlabel\*> Ic q
.Dl ssh:
.Pp
Now that your disk's partitioned, you need to get the proper installation
miniroot image onto it. The miniroot image is designed to be copied into
the swap partition of your disk. This is a safe place which won't be
overwritten by the installation procedure. From the ssh prompt, use the
following commands to copy the miniroot image from tape to swap (b).
.Pp
.Dl ssh: Ic "mt -f /dev/nrst0 rewind"
.Dl ssh: Ic "mt -f /dev/nrst0 fsf 3"
.Dl ssh: Ic "dd bs=8k if=/dev/nrst0 of=/dev/rsd0b"
.Pp
The disk and the miniroot must now be made bootable using the
.Xr installboot 8
command. To do this, issue the following commands:
.Pp
.Dl ssh: Ic "mount /dev/sd0b /mnt"
.Dl ssh: Ic "installboot /mnt/usr/mdec/bootsd /bootxx /dev/rsd0b"
.Dl ssh: Ic "umount /dev/sd0b"
.Pp
You can now shutdown the system.
.Pp
.Dl ssh: Ic halt
.Dl signal 15
.Dl ssh: syncing disks... done
.Dl unmounting / (root_device)...
.Dl halted

.Dl Cold/Warm Reset flag [C,W] = C?

.Pp
Resetting the other types of MVME boards are very similar.
You should now reboot from that just installed miniroot. See the section
entitled
.Sx "Booting the miniroot"
for details.
.
.Ss2 Installing from NFS
.
Before you can install from NFS, you must have already configured
your NFS server to support your machine as a bootable client.
Instructions for configuring the server are found in the section
entitled
.Sx Getting the NetBSD System onto Useful Media
above.
.Pp
To get started on the MVME147, you need to download
.Pa sboot
into RAM (you will find
.Ic sboot
in the
.Pa install
directory of the \*M distribution).
You can either do that through the console line or through a 2nd serial
connection. For example, an MVME147 connected to a sun4/110 and accessed via
.Xr tip 1
can be loaded as follows:
.Pp
.(disp
lo 0
~Ccat sboot
go 4000
.disp)
.Pp
Which will look like this:
.Pp
.Dl 147-Bug\*> Ic "lo 0"
.Dl ~CLocal command? Ic "cat sboot"
.Pp
.Em away for 11 seconds
.Pp
.Dl !
.Pp
.Dl 147-Bug\*> Ic "g 4000"
.Dl Effective address: 00004000
.Pp
.Dl sboot: serial line bootstrap program (end = 6018)
.Pp
.Dl \*>\*>\*>
.Pp
Now, if you want to do it through serial line 1, then connect serial
line one to a machine. At the
.Li 147-Bug\*> No prompt type Ic \&tm 1
You should then login to the machine it is connected to.
Then press
.Key CONTROL-A
to escape to Bug. do
.Ic lo 1;x=cat sboot Em ...
then when that is done you can reconnect
.Ic tm 1 No and logout.
.No Then do Ic go 4000
and you've got the
.Li "\*>\*>\*> "
prompt of
.Ic sboot .
.Pp
Once you've got the
.Li "\*>\*>\*> "
prompt, you can boot the
.Li RAMDISK
kernel from the server:
.Pp
.Dl \*>\*>\*> Ic b
.Pp
.(disp

My ip address is: 192.168.1.4
Server ip address is: 192.168.1.1

Download was a success!
.disp)
.Pp
See below for the next step in booting MVME147.
.Pp
The MVME162, MVME167, MVME172 and MVME177 boards are able to download netboot
directly using TFTP.
To enable this, you must first configure the networking parameters
on the board as described in the section entitled "Preparing your System
for
.Nx
Installation. On a properly configured MVME162/172 or MVME167/177, all you need
to type is:
.Pp
.Dl 1xx-Bug\*> Ic nbo
.Pp
For all board types, the boot messages are very similar:

.Pp
After the boot program loads the
.Li RAMDISK
kernel, you should see the
welcome screen as shown in the "tape boot" section above.
.Pp
You now need to create a disklabel with partition information on the
SCSI disk on which you intend to create your root file system
.Pq Pa / .
Follow the instructions in the previous section entitled
.Sx "Installing from tape"
to do this. (But stop short of the part which describes how to
copy the miniroot from tape.)
.Pp
You must now configure the network interface before you can access the
NFS server containing the miniroot image. For example the command:
.Pp
.Dl ssh: Ic "ifconfig le0 inet 192.168.1.4 up"
.Pp
will bring up the MVME147 network interface
.Li le0
with that address.
The command:
.Pp
.Dl ssh: Ic "ifconfig ie0 inet 192.168.1.4 up"
.Pp
will bring up the MVME162/172 or MVME167/177 network interface
.Li ie0
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 192.168.1.1) You may then need to add a default route if the
server is on a different subnet:
.Pp
.Dl ssh: Ic "route add default 192.168.1.2 1"
.Pp
You can look at the route table using:
.Pp
.Dl ssh: Ic "route show"
.Pp
Now mount the NFS file system containing the miniroot image:
.Pp
.Dl ssh: Ic "mount -r 192.168.1.1:/export/soapy /mnt"
.Pp
The procedure is simpler if you have space for an expanded (not
compressed) copy of the miniroot image. In that case:
.Pp
.Dl ssh: Ic "dd bs=8k if=/mnt/miniroot of=/dev/rsd0b"
.Pp
Otherwise, you will need to use
.Ic zcat
to expand the miniroot image while copying.
This is tricky because the
.Ic ssh
program (small shell) does not handle
.Xr sh 1
pipeline syntax. Instead, you first run the reader
in the background with its input set to
.Pa /dev/pipe
and then run the other program in the foreground with its output to
.Pa /dev/pipe .
The result looks like this:
.Pp
.Dl ssh: Ic "run -bg dd obs=8k if=/dev/pipe of=/dev/rsd0b"
.Dl ssh: Ic "run -o /dev/pipe zcat /mnt/install/miniroot.gz"
.Pp
To load the miniroot using rsh to the server, you would use a pair
of commands similar to the above. Here is another example:
.Pp
.Dl ssh: Ic "run -b dd obs=8k if=/dev/pipe of=/dev/rsd0b"
.Dl ssh: Ic "run -o /dev/pipe rsh 192.168.1.1 zcat miniroot.gz"
.Pp
You must now make the disk bootable. Refer to the previous section on
installing from tape, where it describes how to run
.Ic installboot .
This is immediately following the part which explains how to copy the
miniroot from tape.
.
.Ss2 Booting the miniroot
.
Assuming the miniroot is installed on partition
.Sq Li b
of the disk with
SCSI-ID 0, then the 147Bug boot command is:
.Pp
.Dl 147-Bug\*> Ic "bo 0,,b:"
.Pp
The corresponding 162Bug, 167Bug, 172Bug or 177Bug boot command is:
.Pp
.Dl 1xx-Bug\*> Ic "bo 0,,,b:"
.Pp
The command line parameters above are:
.Pp
.(tag xxx
.It Ic 0
controller (usually zero)
.It Ic ,, or ,,,
bug argument separators
.It Ic \&b:\&
tell the bootstrap code to boot from partition
.Li b
.tag)
.Pp
You should see a bunch of boot messages, followed by messages from
the miniroot kernel just as you did when the
.Li RAMDISK
kernel booted.
.Pp
You will then be prompted to enter the root device. Since the miniroot
was booted from the swap partition, you should enter
.Li sd0b .
You will
then be asked for the swap device and file system type. Just press
.Key RETURN
twice to accept the defaults. When asked to enter a terminal
type, either accept the default, or use whatever the TERM environment
variable is set to in the shell of your host system:
.Pp
.Dl boot device: sd0
.Dl root device (default sd0a): Ic sd0b
.Dl dump device (default sd0b): Em (return)
.Dl file system (default generic): Em (return)
.Dl root on sd0b dumps on sd0b
.Dl mountroot: trying ffs...
.Dl root file system type: ffs
.Dl init: copying out path `/sbin/init' 11
.Dl erase ^H, werase ^W, kill ^U, intr ^C
.Dl Terminal type? [vt100] Em return
.Pp
Congratulations! The system should now be running the miniroot
installation program.
.
.Ss2 Miniroot install program:
.
The miniroot's install program is very simple to use. It will guide
you through the entire process, and is well automated. Additional
improvements are planned for future releases.
.Pp
The miniroot's install program will:
.(bullet
Allow you to place disklabels on additional disks.
The disk we are installing on should already have
been partitioned using the
.Li RAMDISK
kernel.
.Pp
Note that partition sizes and offsets are expressed
in sectors. When you fill out the disklabel, you will
need to specify partition types and file system parameters.
If you're unsure what these values should be, use the
following defaults:
.(disp
fstype: 4.2BSD
fsize: 1024
bsize: 4096
cpg: 16
.disp)
.Pp
If the partition will be a swap partition, use the following:
.(disp
fstype: swap
fsize: 0 (or blank)
bsize: 0 (or blank)
cpg: 0 (or blank)
.disp)
.Pp
Note that partition
.Sq Li c
is special; it covers then entire
disk and should not be assigned to a file system.
.Pp
The number of partitions is currently fixed at 8.
.It
Create file systems on target partitions.
.It
Allow you to set up your system's network configuration.
Remember to specify host names without the domain name
appended to the end. For example use
.Li foo
instead of
.Li 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.
.It
Mount target file systems. You will be given the opportunity
to manually edit the resulting
.Pa /etc/fstab .
.It
Extract binary sets from the media of your choice.
.It
Copy configuration information gathered during the
installation process to your root file system
.Pq Pa / .
.It
Make device nodes in your root file system under
.Pa /dev .
.It
Copy a new kernel onto your root partition
.Pq Pa / .
.It
Install a new boot block.
.It
Check your file systems for integrity.
.bullet)
.Pp
First-time installation on a system through a method other than the
installation program is possible, but strongly discouraged.
