This is the procedure that I have used to install 4.2 BSD onto SIMH's vax 11/780 emulator.

Requirements

You will need the following materials to put together a 4.2 BSD installation:

  • A working perl interpeter to make the tape images.
  • A copy of gzip.
  • A method of extracting the boot file from either the binaries (tar/gzip) or uudecode to extract it from here, or just download it from sourceforge.
  • A compiled binary of vax780 from SIMH, along with the vmb.exe again from SIMH.

An alternative is to download the 4.2 BSD tape from here, along with the boot file here. The bzip2 program will be needed to decompress the tape image.


You will need the following files from any 4 BSD archive from the 4.2 directory. I have used the files from tuhs.superglobalmegacorp.com. You can use whatever method you like to download them, wget, a web browser etc..

ingres.tar.gz
miniroot.gz
new.tar.gz
rootdump.gz
src.tar.gz
srcsys.tar.gz
stand.gz
usr.tar.gz
vfont.tar.gz

Preparing for installation

With the files downloaded you will need to uncompress them all and then create the tape file.

The following command will decompress the tape files.

gzip -d *.gz

The tape needs to be created with the mkdisttap.pl program. Simply run the program and redirect it into a file called 42.tap .

% ./mkdisttap.pl > 42.tap
% ls -l 42.tap
-rw-r--r--  1 Neozeed  +SYSTEM  69943640 Feb  6 12:39 42.tap

Next you will need the boot program. I have uploaded a copy onto this wiki in uuencoded format, and a direct download on sourceforge.net. To use uudeocde to decode it, simply access the article, and copy the contents of the quoted text (the begin/end part INCLUDING the begin & end segments) and save it to a text file. Then you will need to run the uudecode file as follows:

% ls -l boot42.uue
-rw-r--r--  1 Neozeed  None_ploc  9117 Feb  6 12:09 boot42.uue
% uudecode boot42.uue
% ls -l boot42
-rw-------  1 Neozeed  None_ploc  6600 Feb  6 12:28 boot42
% file boot42
boot42: data

Boot 1.

We are going to use the following config file to start the first phase of the installation. Save the following configuration into a file such as 'install.ini'. Since we are going to boot directly into the miniroot the rq1 disk will hold the installation target. Since the 'normal' way to install is to install from tape onto the first disk, we will have to add a device file uppon boot for the second disk, and be sure to point the xtr program to the second disk.

install.ini

set rq0 ra81

set rq1 ra81

set rq2 dis

set tu dis
att ts 42.tap
set tti 7b
set tto 7b
load -o boot42 0
d r10 9
d r11 0
run 2

Booting the emulator

You then simply run the emulator and pass it the config file.

Restoring the rootdump

From here we are now running from the miniroot. The next steps are as follows:

# cd /dev
# ./MAKEDEV ra1
# cd /
# disk=ra1 type=ra81 tape=ts xtr

This will create a 'device' for the ra1 disk, then run the xtr program to restore the root dump.

Boot 2.

Now that the install disk is prepared, we need to use a different config file to reflect us going back to a single disk/tape configuration. The new configuration is as follows:

boot.ini

set rq0 ra81
att rq0 rq.dsk
set rq1 dis
set rq2 dis
set rq3 dis
set rp dis
set lpt dis
set rl dis
set tq dis

load -o boot42 0

Booting the emulator

Now boot up the emulator with the boot.ini

Preparing the disk

Now we have to prep the machine for both the tape, and the type of disk. Type in the following commands.

# disk=ra
# name=ra0h;type=ra81
# cd /dev
# ./MAKEDEV ts0;sync
# cd /
# newfs $name $type

The output will be like this:

# disk=ra
# name=ra0h;type=ra81
# cd /dev
# ./MAKEDEV ts0;sync
# cd /
# newfs $name $type
Warning: 28 sector(s) in last cylinder unallocated

#

Restoring the usr slice

The disk's /usr slice will not have been formatted. We can not go ahead and mount it, and restore the /usr files. Then we unmount the slice, and run fsck to make sure everything is ok.

# mount /dev/$name /usr
# cd /usr
# mkdir sys
# cd sys
# mt rew
# mt fsf 3
# tar xpbf 20 /dev/rmt12
# cd ..
# mt fsf
# tar xpbf 20 /dev/rmt12
# cd /
# chmod 755 / /usr /usr/sys
# rm -rf sys
# ln -s /usr/sys sys
# umount /dev/$name
# fsck /dev/r$name

Likewise, the output should be similar to this:

# chmod 755 / /usr /usr/sys
# rm -rf sys
# ln -s /usr/sys sys
# umount /dev/$name
# fsck /dev/r$name
** /dev/rra0h
** Last Mounted on /usr

** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups

#

Configuring the fstab

Now we just need to create the fstab, format the 'home' slice, and then we can reboot the emulator into multiuser mode. Enter in the following commands:

# cd /etc
# cp fstab.ra81 fstab
# newfs ra0g ra81
# sync
# reboot

And the expected output is as follows:

# cd /etc
# cp fstab.ra81 fstab
# newfs ra0g ra81

/dev/rra0g:     82080 sectors in 115 cylinders of 14 tracks, 51 sectors

First Multiuser Boot

Now we can just re-run the last command, and we should boot multiuser! By default there is no root password. Also the system will run fsck uppon boot, so depending on your host computer this could take a while.

4.2 BSD UNIX (myname)

login:


Now we can simply logon as root.

4.2 BSD UNIX (myname)

login: root
4.2 BSD UNIX #9: Wed Nov 2 16:00:29 PST 1983

Would you like to play a game?

You have mail.
Don't login as root, use su
myname#

From here you can explore the system. All of the man pages are installed, and there is enough of a base system to get going. Sadly there are bugs in how 4.2 BSD and how SIMH interact with the networking, and it is not reliable. As sad as it is to be an 'island' you can however setup the dz serial interface to allow more than one user.

Enabling remote users

You can add the following lines into the boot.ini (just make sure they are above the boot command or it'll not work correctly..). This will allow for 8 users to connect on tcp port 8888.

set dz lines=8
set dz 7b
att dz -m 8888

I would also recommend to windows users, either putty, or syncterm. The default telnet client sucks.
