Installing 4.3 BSD Quasijarus on SIMH

This is the procedure that I have used to install 4.3 BSD onto SIMH's MicroVAX II emulator. Please note that this is the Quasijarus release of 4.3 BSD.

Requirements

You will need the following materials to put together a 4.3 BSD Quasijarus installation:

• A working perl interpeter to make the tape images.
  
• A copy of gzip.
  
• A working C compiler.
  
• 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.

You will need the following files from any 4 BSD archive from the 4.2 directory. I have used the files from [1]. You can use whatever method you like to download them, wget, a web browser etc..

stand.Z
miniroot.Z
rootdump.Z
usr.tar.Z
srcsys.tar.Z
src.tar.Z

gzcompat

Next it's easier on a host machine to convert the downloaded Quasijarus files into gzip, then uncompress them using gzip. For this you will need the gzcompat program. I've included the sourcecode on the link, as it's getting harder to find.. Simply compile the gzcompat.c into an exe. It should be somewhat straightforward. The last known place to download gzcompat is [here].

On most instances with gcc simply run:

gcc gzcompat.c -o gzcompat

And that should be it.

Preparing for installation

With the files downloaded you will need to uncompress them all and then create the tape file. With the different compression this will be somewhat involved.

The following command will decompress the tape files, on a UNIX install. For Windows users, use the type command, instead of cat.

cat miniroot.Z | gzcompat | gzip -dc > miniroot
cat rootdump.Z | gzcompat | gzip -dc > rootdump
cat src.tar.Z | gzcompat | gzip -dc > src.tar
cat srcsys.tar.Z | gzcompat | gzip -dc > srcsys.tar
cat stand.Z | gzcompat | gzip -dc > stand
cat usr.tar.Z | gzcompat | gzip -dc > usr.tar

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

% ./mkdisttap.pl  > quas.tap
% ls -l quas.tap
-rw-r--r--  1 Neozeed  None_ploc  84450876 Feb  6 17:10 quas.tap
%

Now we have our tape, so we are ready to proceed with the install. For those wondering, unlike the 11/780 emulator, the MicrovaxII can run it's microcode in a logical fashion and we are able to boot from tape in this release.

Boot 1.

I disable as many of the devices as possible to get a 'clean' install. So this is the install.ini that I'm going to use.

install.ini

set cr dis
set lpt dis
set rl dis
set ry dis
set ts dis
set xq dis
set rq0 ra81
att rq0 quas.dsk
set rq1 dis
set rq2 dis
set rq3 dis
att tq0 quas.tap
set tti 7b
set tto 7b
boot cpu

Booting the emulator

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

C:\Quasijarus0c\work>vax.exe install.ini

Once the BIOS has done it's POST, it will prompt what device to boot off of at the >>> prompt. The first tape device is mua0:. Once the tape has done the first boot you'll be greeted with the = prompt. From here we are going to load the copy program. Simply type in the following:

copy
tms(0,1)
ra(0,1)

This will copy the second file onto tape, onto the second file position on our hard disk. The output should be the following:

=copy
cpu: uVAX 3000
From: tms(0,1)
To: ra(0,1)
ra0: unlabeled
Copy completed: 308 records copied
=

Next we run the boot program. Simply type in the following:

boot
ra(0,1)vmunix

The resulting output should be the following. The kernel will then prompt for the root partition.

=boot
cpu: uVAX 3000

Boot

root device?

We will answer with the first ra disk, in a special format, because we have not put a disklabel onto the disk yet.

ra0*

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.

erase ^?, kill ^U, intr ^C
# cd /dev
# ./MAKEDEV ra1
./MAKEDEV: chgrp: not found
./MAKEDEV: chmod: not found
# cd /

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

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
# sh ./MAKEDEV ts0;sync
# cd /
# newfs $name $type

The output will be like this:

# disk=ra
# name=ra0h;type=ra81
# cd /dev
# sh ./MAKEDEV ts0;sync
# cd /
# newfs $name $type
Warning: 680 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:

# 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

#

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:

# cp fstab.ra81 fstab
# newfs ra0g ra81

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.

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

Inside of BSD 4.3 you will have to create the dz device files. Simply logon as root, and run the following commands:

cd /dev
sh ./MAKEDEV dz0

Next, 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..

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.
