Installing 4.3 BSD NFS Wisconsin Unix
Contents
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 boothp.uue -rw-r--r-- 1 Neozeed None 10683 Apr 7 20:15 boothp.uue % uudecode boothp.uue % ls -l boothp -rw------- 1 Neozeed None 7736 Apr 7 20:20 boothp % file boothp boothp: 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 dis set rq1 dis set rq2 dis set rq3 dis set rp0 rp06 att rp0 miniroot set rp1 rp06 att rp1 rp06.disk set rp2 dis set rp3 dis set rp4 dis set rp5 dis set rp6 dis set rp7 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 boothp 0 d r10 0 d r11 0 run 2
Booting the emulator
You then simply run the emulator and pass it the config file. You will be prompted to "overwrite last track" answer y and hit enter.
% ./vax780 install.ini

Restoring the rootdump
From here we are now running from the miniroot. The next steps are as follows:
# cd /dev # ./MAKEDEV hp1 # cd / # disk=hp1 type=rp06 tape=ts xtr
This will create a 'device' for the hp1 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 hp1
syntax error
./MAKEDEV: chgrp: not found
./MAKEDEV: chmod: not found
# cd /
# disk=hp1 type=rp06 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

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=hp # name=hp0g;type=rp06 # cd /dev # sh ./MAKEDEV ts0;sync # cd / # newfs $name $type
The output will be like this:
# newfs $name $type

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.
