Installing 4.3 BSD NFS Wisconsin Unix

Requirements

You will need the following materials to put together a 4.3 BSD+NFS Wisconsin Unix 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.
  
• A compiled binary of vax780 from SIMH, along with the vmb.exe again from SIMH.
• The Mkdisttap.pl program, you can take the settings from Quasijarus as the names & block sizes match up.

You will need the following files from any 4 BSD archive from the 4.3BSD directory. I have used the files from mirror.cc.vt.edu. You can use whatever method you like to download them, wget, a web browser etc..

stand.gz
miniroot.gz
rootdump.gz
usr.tar.gz
srcsys.tar.gz
src.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 uwisc.tap .

% ./mkdisttap.pl > uwisc.tap
% ls -l uwisc.tap
-rw-r--r--  1 Neozeed  None  74337572 Apr  7 19:40 uwisc.tap

Next you will need the boot program. The boot program from 4.2 BSD works with 4.3 BSD. I have uploaded a copy onto this wiki in uuencoded format. 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  9117 Apr  7 19:42 boot42.uue
% uudecode boot42.uue
% ls -l boot42
-rw-------  1 Neozeed  None  6600 Apr  7 19:42 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
at rq0 miniroot
set rq1 ra81
at rq1 rq.dsk
set rq2 dis
set rq3 dis
set rp dis
set lpt dis
set rl dis
set tq dis
set tu dis
att ts uwisc.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.

% ./vax780  install.ini

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. Take note that the chgrp & chmod commands are not found, however the install will proceed as normal.

# cd /dev
# ./MAKEDEV ra1
syntax error
./MAKEDEV: chgrp: not found
./MAKEDEV: chmod: not found
# cd /
# disk=ra1 type=ra81 tape=ts xtr

After this stage, I just sync the disk a few times, then halt the emulator (CONTROL+E) and exit out. Now we are ready for stage two.

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

Booting the emulator

Now boot up the emulator with the boot.ini

% ./vax780  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=hp
# name=hp0g;type=rp06
# cd /dev
# sh ./MAKEDEV ts0;sync
# cd /
# newfs $name $type

The output will be like this:

# newfs $name $type
Warning: 154 sector(s) in last cylinder unallocated
/dev/rhp0g:     291192 sectors in 697 cylinders of 19 tracks, 22 sectors

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
# mt rew
# mt fsf 3
# tar xpbf 20 /dev/rmt12
# cd sys
# mt fsf
# tar xpbf 20 /dev/rmt12

Life interrupts again... I'll have to finish later.. but it's just like a 4.3 BSD install.
