Or, if you have an MVME162-LX or MVME167 board (the following boot message is from MVME167; MVME162-LX is similar):

MVME167 Debugger/Diagnostics Release Version 2.3 - 02/25/94
COLD Start
     

Local Memory Found =02000000 (&33554432)
     

MPU Clock Speed =33Mhz
     

167-Bug>

Make sure the RAM size looks ok (if you've got an 8 MB MVME147 or a 32 MB MVME167 you should have the same value as we do). Also make sure the clock is ticking:

       1xx-Bug>time
       Sunday 12/21/31 16:25:14
       1xx-Bug>time
       Sunday 12/21/31 16:25:15
       1xx-Bug>

Note that NetBSD bases its year at 1968, and adds the year offset in the system's real-time clock to get the current year. So the 31 here equates to 1999. You may have to adjust your clock using the set command to comply with NetBSD 's requirements. Don't worry if the `Day of the week' is not correct, as NetBSD doesn't use it. Motorola has acknowledged a year 2000 bug in some versions of the MVME147 whereby the day of the week doesn't get set correctly by the 147Bug PROM. does not affect NetBSD !

Also make sure that your board's ethernet address is initialised to the correct value. You'll find the address on a label on the inside of the MVME147's front panel, and on the VMEbus P2 connector of the MVME162-LX and MVME167. On the MVME147, enter the last five digits of the address using the lsad command. On the MVME162-LX and MVME167, you should use the cnfg command.

To install successfully to a local SCSI disk, you need to ensure that the system is aware of what targets are connected to the SCSI bus. This can be done by issueing the following command:

       1xx-Bug> iot;t

At this point, Bug will scan for any attached SCSI devices. After a short delay, a list of SCSI devices will be displayed. 147Bug will ask if LUNs should be assigned from SCSI ids, to which you should answer Y. You should also answer Y when asked if the information is to be saved to NVRAM. 16xBug does not prompt for this information.

The following installation instructions will assume that your target SCSI disk drive appears at SCSI-ID 0. If you have a tape drive, the instructions assume is is configured for SCSI-ID 5. When the RAMDISK root boots, NetBSD will refer to these devices as sd0 and rst0 respectively. You may wish to note these down; you'll be using them a lot. :-)

Installing the NetBSD System

Installing NetBSD is a relatively complex process, but if you have this document in hand it should not be too difficult.

There are several ways to install NetBSD onto your disk. If your machine has a tape drive the easiest way is Installing from tape (details below). If your machine is on a network with a suitable NFS server, then Installing from NFS is the next best method. Otherwise, if you have another mvme68k machine running NetBSD you can initialize the disk on that machine and then move the disk.

Installing from tape

       147-Bug> bo 5

       16x-Bug> bo 0,50

As mentioned earlier, this assumes your tape is jumpered for SCSI-ID 5.

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 NetBSD. They are of the form:

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

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.

Here is an example of an MVME147 system booting from tape:

Note:

The exact text of the messages will vary depending on which mvme68k variant you're using.

Finally, you will see the following "welcome" message:

        Welcome to the NetBSD/mvme68k 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
halt,
then at the Bug monitor prompt use a command like:
          1x7Bug> bo 0,,b:
     

To view this message again, type:  cat /.welcome
ssh:

You must now create a disklabel on the disk you wish to use for the root file system (/). This will usually be sd0. The disklabel is used by NetBSD to identify the starting block and size of each partition on the disk.

Partitions are named sd0a, sd0b, sd0c, etc, up to sd0h. The mvme68k port of NetBSD makes some assumptions about the first three partitions on a boot disk:

sd0a

The root file system (/).

sd0b

The swap partition.

sd0c

The whole disk. Also known as the raw partition.

The raw partition is special; NetBSD 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.

It is good practice to put /usr on a different partition than / (root, AKA sd0a). So, the first available partition for /usr is sd0d. Refer to the section entitled NetBSD System Requirements and Supported Devices for information on the recommended sizes of the / (root), /usr and swap partitions.

You are not required to define any partitions beyond sd0d, but if you have a large disk drive, you might want to create several other partitions for file systems such as /home or /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 miniroot installation program.

To create the disklabel and partitions, use the edlabel program, passing it the name of the Raw Partition of your root/boot disk.

       ssh: edlabel /dev/rsd0c
       edlabel menu:
       print - display the current disk label
       modify - prompt for changes to the label
       write - write the new label to disk
       quit - terminate program
       edlabel>

The program shows what commands it recognizes; print, modify, write, and quit. It will accept the first letter of a command if you don't feel like typing each one in full.

To start creating the basic partitions, you should enter m (modify) at the edlabel prompt, then enter the letter corresponding to the first partition, a.

       edlabel> m

       modify subcommands:
       @: modify disk parameters
       a-h: modify partition
       s: standarize geometry
       q: quit this subcommand
       edlabel/modify> a
       a (root) 0 (0/00/00) 0 (0/00/00) unused
       start as <blkno> or <cyls/trks/sects>: 0
       length as <nblks> or <cyls/trks/sects>: 65536
       type: 4.2BSD
       edlabel/modify>

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 NetBSD, it's probably easiest to use block notation. The above example creates partition `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.

The type of the partition should be 4.2BSD, otherwise you won't be able to create a file system on it.

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 NetBSD installation!

       edlabel/modify> b
       b (swap) 0 (0/00/00) 0 (0/00/00) unused
       start as <blkno> or <cyls/trks/sects>: 65536
       length as <nblks> or <cyls/trks/sects>: 32768
       type: swap
       edlabel/modify>

Here, we specify a value for start such that the swap partition follows immediately after partition `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 `d' for our /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.)

       edlabel/modify> d
       d (user) 0 (0/00/00) 0 (0/00/00) unused
       start as <blkno> or <cyls/trks/sects>: 98304
       length as <nblks> or <cyls/trks/sects>: 1540096
       type: 4.2BSD
       edlabel/modify> q
       edlabel>

As you can see, we've chosen to assign the remainder of the disk to /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 d starts at sector 98304, a simple bit of arithmetic (1638400 - 98304) gives d a size of 1540096.

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.

You now need to write this new disklabel, together with the partition details you've just entered, to disk. You might also try the `p' command to view the partitions. Once written, you can quit back to ssh using `q'.

       edlabel> p

     type_num: 4

 d (user)      98304      (48/00/00)    1540096     (752/00/00)  4.2BSD

       edlabel> w
       edlabel> q
       ssh:

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).

       ssh: mt -f /dev/nrst0 rewind
       ssh: mt -f /dev/nrst0 fsf 3
       ssh: dd bs=8k if=/dev/nrst0 of=/dev/rsd0b

The disk and the miniroot must now be made bootable using the installboot(8) command. To do this, issue the following commands:

       ssh: mount /dev/sd0b /mnt
       ssh: installboot /mnt/usr/mdec/bootsd /bootxx /dev/rsd0b
       ssh: umount /dev/sd0b

You can now shutdown the system.

       ssh: halt
       signal 15
       ssh: syncing disks... done
       unmounting / (root_device)...
       halted

       147-Bug> reset
       Reset Local SCSI Bus [Y,N] N? y
       Automatic reset of known SCSI Buses on RESET [Y,N] Y?
       Cold/Warm Reset flag [C,W] = C?
       Execute Soft Reset [Y,N] N? y

Resetting the MVME162-LX and MVME167 boards are very similar. You should now reboot from that just installed miniroot. See the section entitled Booting the miniroot for details.

Installing from NFS

To get started on the MVME147, you need to download sboot into RAM (you will find sboot in the install directory of the mvme68k 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 tip(1) can be loaded as follows:

lo 0
~Ccat sboot
go 4000

Which will look like this:

       147-Bug> lo 0
       ~CLocal command? cat sboot

away for 11 seconds

       !

       147-Bug> g 4000
       Effective address: 00004000

       sboot: serial line bootstrap program (end = 6018)

       >>>

Now, if you want to do it through serial line 1, then connect serial line one to a machine. At the 147-Bug> prompt type tm 1 You should then login to the machine it is connected to. Then press CONTROL-A to escape to Bug. do lo 1;x=cat sboot ... then when that is done you can reconnect tm 1 and logout. Then do go 4000 and you've got the >>> prompt of sboot.

Once you've got the >>> prompt, you can boot the RAMDISK kernel from the server:

       >>> b

le0: ethernet address: 8:0:3e:20:cb:87
My ip address is: 192.168.1.4
Server ip address is: 192.168.1.1
4800
Download was a success!

See below for the next step in booting MVME147.

The MVME162-LX and MVME167 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 NetBSD Installation. On a properly configured MVME162-LX or MVME167, all you need to type is:

       16x-Bug> nbo

For all board types, the boot messages are very similar:

After the boot program loads the RAMDISK kernel, you should see the welcome screen as shown in the "tape boot" section above.

You now need to create a disklabel with partition information on the SCSI disk on which you intend to create your root file system (/). Follow the instructions in the previous section entitled Installing from tape to do this. (But stop short of the part which describes how to copy the miniroot from tape.)

You must now configure the network interface before you can access the NFS server containing the miniroot image. For example the command:

       ssh: ifconfig le0 inet 192.168.1.4 up

will bring up the MVME147 network interface le0 with that address. The command:

       ssh: ifconfig ie0 inet 192.168.1.4 up

will bring up the MVME162-LX or MVME167 network interface 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:

       ssh: route add default 192.168.1.2 1

You can look at the route table using:

       ssh: route show

Now mount the NFS file system containing the miniroot image:

       ssh: mount -r 192.168.1.1:/export/soapy /mnt

The procedure is simpler if you have space for an expanded (not compressed) copy of the miniroot image. In that case:

       ssh: dd bs=8k if=/mnt/miniroot of=/dev/rsd0b

Otherwise, you will need to use zcat to expand the miniroot image while copying. This is tricky because the ssh program (small shell) does not handle sh(1) pipeline syntax. Instead, you first run the reader in the background with its input set to /dev/pipe and then run the other program in the foreground with its output to /dev/pipe. The result looks like this:

       ssh: run -bg dd obs=8k if=/dev/pipe of=/dev/rsd0b
       ssh: run -o /dev/pipe zcat /mnt/install/miniroot.gz

To load the miniroot using rsh to the server, you would use a pair of commands similar to the above. Here is another example:

       ssh: run -b dd obs=8k if=/dev/pipe of=/dev/rsd0b
       ssh: run -o /dev/pipe rsh 192.168.1.1 zcat miniroot.gz

You must now make the disk bootable. Refer to the previous section on installing from tape, where it describes how to run installboot. This is immediately following the part which explains how to copy the miniroot from tape.

Booting the miniroot

       147-Bug> bo 0,,b:

The corresponding 162Bug or 167Bug boot command is:

       16x-Bug> bo 0,,,b:

The command line parameters above are:

0

controller (usually zero)

,, or ,,,

bug argument separators

b:

tell the bootstrap code to boot from partition b

You should see a bunch of boot messages, followed by messages from the miniroot kernel just as you did when the RAMDISK kernel booted.

You will then be prompted to enter the root device. Since the miniroot was booted from the swap partition, you should enter sd0b. You will then be asked for the swap device and file system type. Just press 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:

       boot device: sd0
       root device (default sd0a): sd0b
       dump device (default sd0b): (return)
       file system (default generic): (return)
       root on sd0b dumps on sd0b
       mountroot: trying ffs...
       root file system type: ffs
       init: copying out path `/sbin/init' 11
       erase ^H, werase ^W, kill ^U, intr ^C
       Terminal type? [vt100] return

Congratulations! The system should now be running the miniroot installation program.

Miniroot install program:

The miniroot's install program will:

• Allow you to place disklabels on additional disks. The disk we are installing on should already have been partitioned using the RAMDISK kernel.

  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:

  fstype: 4.2BSD
  fsize: 1024
  bsize: 4096
  cpg: 16
  

  If the partition will be a swap partition, use the following:

  fstype: swap
  fsize: 0 (or blank)
  bsize: 0 (or blank)
  cpg: 0 (or blank)
  

  Note that partition `c' is special; it covers then entire disk and should not be assigned to a file system.

  The number of partitions is currently fixed at 8.

• Create file systems on target partitions.

• 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 foo instead of 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.

• Mount target file systems. You will be given the opportunity to manually edit the resulting /etc/fstab.

• Extract binary sets from the media of your choice.

• Copy configuration information gathered during the installation process to your root file system (/).

• Make device nodes in your root file system under /dev.

• Copy a new kernel onto your root partition (/).

• Install a new boot block.

• Check your file systems for integrity.

First-time installation on a system through a method other than the installation program is possible, but strongly discouraged.

Post installation steps

Once you've got the operating system running, there are a few things you need to do in order to bring the system into a properly configured state, with the most important ones described below.

1. Configuring /etc/rc.conf

   If you or the installation software haven't done any configuration of /etc/rc.conf, the system will drop you into single user mode on first reboot with the message

          /etc/rc.conf is not configured. Multiuser boot aborted.
   

   and with the root file system (/) mounted read-write. When the system asks you to choose a shell, simply press RETURN to get to a prompt. If you are asked for a terminal type, respond with vt220 (or whatever is appropriate for your terminal type) and press RETURN. At this point, you need to configure at least one file in the /etc directory. Change to the /etc directory and take a look at the /etc/rc.conf file. Modify it to your tastes, making sure that you set rc_configured=YES so that your changes will be enabled and a multi-user boot can proceed. Default values for the various programs can be found in /etc/defaults/rc.conf, where some in-line documentation may be found. More complete documentation can be found in rc.conf(5).

   If your /usr directory is on a separate partition and you do not know how to use ed, you will have to mount your /usr partition to gain access to ex or vi. Do the following:

   
          # mount /usr
   
          # export TERM=vt220
   

   If you have /var on a separate partition, you need to repeat that step for it. After that, you can edit /etc/rc.conf with vi(1). When you have finished, type exit at the prompt to leave the single-user shell and continue with the multi-user boot.

   Other values that need to be set in /etc/rc.conf for a networked environment are hostname and possibly defaultroute, furthermore add an ifconfig_int for your interface <int>, along the lines of

   
          ifconfig_de0="inet 123.45.67.89 netmask 255.255.255.0"
   

   or, if you have myname.my.dom in /etc/hosts:

   
          ifconfig_de0="inet myname.my.dom netmask 255.255.255.0"
   

   To enable proper hostname resolution, you will also want to add an /etc/resolv.conf file or (if you are feeling a little more adventurous) run named(8). See resolv.conf(5) or named(8) for more information.

   Other files in /etc that may require modification or setting up include /etc/mailer.conf, /etc/nsswitch.conf, and /etc/wscons.conf.

2. Logging in

   After reboot, you can log in as root at the login prompt. There is no initial password, but if you're using the machine in a networked environment, you should create an account for yourself (see below) and protect it and the ``root'' account with good passwords. Unless you have connected an unusual terminal device as the console you can just press RETURN when it prompts for Terminal type? [...]

3. Adding accounts

   Use the useradd(8) command to add accounts to your system, do not edit /etc/passwd directly. See useradd(8) for more information on how to add a new user to the system.

4. The X Window System

   If you have installed the X window system, look at the files in /usr/X11R6/lib/X11/doc for information.

   Don't forget to add /usr/X11R6/bin to your path in your shell's dot file so that you have access to the X binaries.

5. Installing third party packages

   If you wish to install any of the software freely available for UNIX-like systems you are strongly advised to first check the NetBSD package system. This automatically handles any changes necessary to make the software run on NetBSD, retrieval and installation of any other packages on which the software may depend, and simplifies installation (and deinstallation), both from source and precompiled binaries.

   • More information on the package system is at http://www.netbsd.org/Documentation/software/packages.html

   • A browsable listing of available packages is at ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/README.html

   • Precompiled binaries can be found at ftp://ftp.netbsd.org/pub/NetBSD/packages/

   • Package sources for compiling packages can be obtained by retrieving the file ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/tar_files/pkgsrc.tar.gz They are typically extracted into /usr/pkgsrc (though other locations work fine), as with the command:

     
            # mkdir /usr/pkgsrc; tar -C /usr/pkgsrc -zxpf pkgsrc.tar.gz
     

     After extracting, then see the README file in the extraction directory (e.g. /usr/pkgsrc/README) for more information.

6. Misc

   • Edit /etc/mail/aliases to forward root mail to the right place (run newaliases(1) afterwards.)

   • The /etc/mail/sendmail.cf file will almost definitely need to be adjusted; files aiding in this can be found in /usr/share/sendmail. See the README file there for more information.

   • Edit /etc/rc.local to run any local daemons you use.

   • Many of the /etc files are documented in section 5 of the manual; so just invoking

     
            # man 5 filename
     

     is likely to give you more information on these files.
