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. 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.

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

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 dis
set rq1 dis
set rq2 dis
set rq3 dis
set rp0 rp06
att rp0 rp06.disk
set rp1 dis
set rp2 dis

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=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

 267744, 274456, 281168, 287880,


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/$name /usr
# cd /usr
# mkdir sys
# mt rew
# mt fsf 3
# tar xpbf 20 /dev/rmt12
# cd sys
# mt fsf
# tar xpbf 20 /dev/rmt12
# cd /
# umount /dev/$name
# fsck /dev/r$name

Likewise, the output should be similar to this: 

# mount /dev/$name /usr
# cd /usr
# mkdir sys
# mt rew
# mt fsf 3
# tar xpbf 20 /dev/rmt12
# cd sys
# mt fsf
# tar xpbf 20 /dev/rmt12
# cd /
# umount /dev/$name
# fsck /dev/r$name

***** FILE SYSTEM WAS MODIFIED *****

There will always be some errors it would seem.... Also this is more of a dump of an existing system, not a 'distribution' tape, so there are some things we have to take care of.

The password file needs to be 'fixed' because I don't have the root password.... 

root::0:1:The Not Ready for Prime Time Super User:/:/bin/csh
daemon:*:1:1:The devil himself:/:
operator:*:5:5:Operator:/usr/operator:/bin/csh
tty::4:4:Which tty am I:/bin:/usr/bin/tty
news:vXHPueUygRELQ:6:6:The News:/usr/lib/news:/bin/csh
uucp:GbeWaSRwdvDCE:66:66:UNIX-to-UNIX Copy:/usr/spool/uucppublic:/usr/lib/uucp/uucico
tadl:XyGpEqJu78.Rg:1433:10:Tad Lebeck,2289C,27950,2515517:/usr/staff/tadl:/bin/csh
nobody:nopass:32767:32767:Nonexistent user:/nonexistent:/dev/null

simply catting that into /etc/passwd should do the trick if you have a 'console' that you can paste text into....!

The next thing that will have to be fixed is the fstab. 

/dev/hp0a / 4.2 rw,noquota 1 1
/dev/hp0g /usr 4.2 rw,noquota 1 2

Again cat that into /etc/fstab .

Finally let's add the DZ device files, and the ptys... 

# cd /dev
# sh ./MAKEDEV dz0
# sh ./MAKEDEV pty0

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.

Enabling remote users

Shutdown the OS, and 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
att dz 8888
set dz 7b

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

fixing if_de.c

On my SLiRP builds, I've noticed that the interface just generates errors, but it should work. It was easier to 'fix' the BSD device driver...

So in the derecv procedure apply the following fix: 

        /* check for errors */
        if(1==2){
/**     if ((rp->r_flags & (RFLG_ERRS|RFLG_FRAM|RFLG_OFLO|RFLG_CRC)) ||
