Installing Ultrix 4.5 on SIMH
This WORK-IN-PROGRESS guide will be a simple guide to installing ULTRIX 4.5 for VAX on SIMH.
Contents
Requirements
The following is a list of things required for installation
- A recent version of the SIMH emulator
- Make sure the binary you're using includes Ethernet support
- I'm using a self-compiled version (git revision 0e8c0aea)
- An ISO image of ULTRIX 4.5 for VAX
- See the "Resources" section for a download link
- It's probably also possible to install it from tape, although I don't know if any installation tapes for ULTRIX 4.5 exist
- Optional stuff (might get added to the guide later):
- Starfish Ultrix Freeware CDs from here
SimH configuration
The machine I'm using to run ULTRIX has the following configuration
- DEC MicroVAX 3800
- 64mb memory
- DELQA network card (XQ0)
- Two RA90 disk drives (with 1.2gb each) attached to an RQDX3 controller (RQ0 and RQ1)
- CD ROM drive attached to the same RQDX3 controller as unit 2 (RQ2)
- TK50 tape attached as unit 0 on the first TQK50 controller (TQ0)
- DZV11 terminal multiplexer with 16 lines, attached to telnet port 1005 (DZ)
- LPT line printer attached to text file
printer_output.txt
Here's my config file (I called it simh.conf)
; ; SimH 4.0 Configuration file for MicroVAX 3800 ; ; Host System : DEC MicroVAX 3800 ; Operating System : DEC Ultrix v4.5 ; Memory : 64mb ; Network config : XQ: Ethernet, 08:00:2b:04:14:02 ; Disks : RQ0: RA90, 1.2gb ; RQ1: RA90, 1.2gb ; CDROMs : RQ2: iso file ; Tape config : TQ0: TK50, 94mb ; load -r ka655x.bin ; NVRAM attach NVR nvram.bin ; CPU config set CPU 64m set CPU conhalt set CPU idle=all ; configure console to 7-bit only set TTO 7b set TTI 7b ; Disk drives set RQ0 ra90 attach RQ0 rq0-ra90.dsk set RQ1 ra90 attach RQ1 rq1-ra90.dsk set RQ2 CDROM attach -r RQ2 ultrix-vax-os-v4.5.mode1.ufs.iso ; MD5 sum: 19df0753c27f195e9f1d2f139a3b4629 *ultrix-vax-os-v4.5.mode1.ufs.iso set RQ3 dis ; Tape set TQ tk50 ;attach tq0 filename-to-tape-file set TQ1 dis set TQ2 dis set TQ3 dis ; serial port, simulated by Telnet to port 1005 set DZ LINES=16 set DZ 8B attach DZ 1005 NoBuffer ; printer set LPT enable attach LPT printer_output.txt ; Disable unused peripherals set CR dis set RL dis set TS dis ; Network interface (08-00-2b is the DEC prefix, the 04-14-02 part is arbitrary) set XQ MAC=08-00-2b-04-14-02 attach XQ0 eth0 ; serial console (launch directly after booting CPU) set console telnet=1001 ; experimental ;set QVSS en ; boot the system ;boot CPU
Note that I'm using a telnet console (for easier copy/paste on Windows), which means that directly after running this config file (via do simh.conf from Simh) you will need to connect via telnet to localhost:1001 or the boot will abort. If you are on Linux, or just don't want that, remove the set console telnet=1001 line.
Also note that you might need to attach XQ0 to a different ethernet device. Use "show ether" in SimH to list all available devices on your system and modify the attach XQ0 eth0 line accordingly.
Running the Emulator
Either run vax.exe simh.conf from the Windows command line, or just double-click the VAX.EXE executable and type do simh.conf.
On the first launch it might take some time because SimH has to create the disk images (~2.5 gb total). It should look something like this

sim>
Type the following to start the emulation (note: you can also uncomment that line from the end of the config file to have the emulation start right away)
sim> boot cpu Waiting for console Telnet connection
Now would be a good time to connect your telnet session (I use a batch file for this), otherwise the boot process will timeout.
On your console, you should see something like this:
Connected to the MicroVAX 3900 simulator CON-TEL device KA655-B V5.3, VMB 2.7 Performing normal system tests. 40..39..38..37..36..35..34..33..32..31..30..29..28..27..26..25.. 24..23..22..21..20..19..18..17..16..15..14..13..12..11..10..09.. 08..07..06..05..04..03.. Tests completed. >>>
This is the VAX's boot prompt. Normally you just type
>>>boot <device>
where <device> is one of the following
- MUA<num>: TK tape device number <num> (1 to 4)
- DUA<num>: RQ disk device number <num> (1 to 4)
You can use show device to see the installed (and detected) devices you can boot from, and show boot to see which device will be the default if you just type boot (or b for short):
>>>show device UQSSP Disk Controller 0 (772150) -DUA0 (RA90) -DUA1 (RA90) -DUA2 (RRD40) UQSSP Tape Controller 0 (774500) -MUA0 (TK50) Ethernet Adapter 0 (774440) -XQA0 (08-00-2B-04-14-02) >>>show boot MUA0
Since we want to boot from CDROM, which is unit 2, we can use
>>>boot DUA2
Note: You can add flags to boot into single user mode, or to boot in interactive mode (so-called conversational boot, where the system prompts you for a kernel file name to load). For details see the Guide to ULTRIX-32 System Startup and Shutdown, linked to in the References section. To use it, add the /R5:<flags> option to the boot command, where flags is 0 (default multi-user), 1 (conversational multi-user), 2 (single-user) or 3 (conversational single-user). For example
>>>boot/r5:3 dua0
Note: You can also boot from ethernet (boot XQA0) but this requires a DEC-specific boot server in your network (the protocol is called MOP for Maintenance Operations Protocol), which is beyond the scope of this document. I did get it to work a few years ago though, but it was a bit difficult to set up.
For a list and description of all commands available in the bootloader (hint: there are lots), see the KA655 CPU System Maintenance guide mentioned in the References section..
Bootstrapping ULTRIX
You will see the following output on the first boot.

*** STANDALONE ULTRIX ENVIRONMENT ***
If you select the BASIC Installation option from the list that follows,
the installation software creates file systems on default partitions on
your system disk and loads the mandatory ULTRIX software subsets.
If you require additional installation choices, select the ADVANCED
Installation option.
Select one of the following options:
1) BASIC Installation
2) ADVANCED Installation
3) System management
Enter your choice:
Now we want to do an ADVANCED Installation, but when we try to, it will take a few seconds until the installation program dumps us to a prompt because it couldn't find a valid device to install from and to:
Enter your choice: 2 *** SOFTWARE DISTRIBUTION DEVICE SELECTION *** The 'Guide to Installing ULTRIX' explains the following table of software distribution devices and which installation media you should load on it: No valid device is found. Contact a DIGITAL field service representative. #
The problem seems to be that the hardware SimH emulates is not fully supported by ULTRIX (or is misdetected -- I'm not entirely sure myself). The good thing is that the internet has the correct solution, which is to fix some lines in the installation shell script. The fact that the basic system that is running at this point doesn't have vi, or even cat, makes this a bit harder ;-)
The only option you have is ed, the old UNIX editor. For a quick introduction, see here.
To load the file in the editor, use
# ed install.1 16763
You can see the entire file with
1,$l
but be warned, the output is quite long and it'll take some time to print it all out.
To fix it, use the following commands (the lines in bold is what you type, everything else is the response from ed)
# ed install.1 16763 173l BTD=`btd` 173s/`btd`/ra2/ 173l BTD=ra2 193l rz* ) 193s/rz/ra/ 193l ra* ) w 16761 q #
First, we list line 173, then we change it from BTD=`btd` to BTD=ra2, which happens to be the CDROM device and unit number we're installing from (if you changed that in your config, use the correct name here!)
Then we change line 193 from rz* ) to ra* ) since we're trying to install on an RA type disk which was apparently not supported in ULTRIX out of the box.
Note: These changes also work for Ultrix 4.3 and 4.4. If you would like to try 4.2, use 164 instead of 173 and 184 instead of 193.
After writing the file with w and quitting ed with q, we're back at the prompt, at which point we can use CTRL+D to retry the installation:
# ^D

*** SYSTEM DISK SELECTION ***
The 'Guide to Installing ULTRIX' explains the following table
of system disk drives. Select one of the devices below to contain the
root file system:
SYSTEM DISK TABLE

Enter your choice: 1
You selected RA90, device number 0. Make sure this disk drive
is on line and write-enabled (if applicable to your disk drive), then
confirm your choice.
Use RA90, ra0, for your system disk? (y/n) []: y
The installation procedure now allocates the root file system on
partition 'a' of the system disk, ra0 RA90.

*** BOOTSTRAP COMMAND SEQUENCE ***
Enter the following boot sequence at the console mode prompt
after the installation software halts the processor:
>>> b dua0
syncing disks... done
?06 HLT INST
PC = 8007F799
>>>
After this, you will be back at the VAX boot prompt (if you used set CPU CONHALT in your config) or at the SimH emulator prompt (if you used set CPU SIMHALT, which is the default). In the latter case you will have to do boot cpu again to get to the VAX boot prompt.
First boot
Now we can boot the installed system from harddisk for the first time.
If you want to, now would be a good time to take a backup copy of your disk files (or just create a btrfs snapshot or something if you have the possibility ;-)
Okay, then let's boot from DUA0

Here, it will seem to hang for a loooong time. A few minutes. Don't worry, it will eventually continue to boot. I guess it's probing for other devices which are not present.
You might be able to speed this up a bit by interrupting SimH (press CTRL+E in the SimH console window) and then using set CPU noidle followed by go to resume emulation.
Eventually, you will have to decide on a hostname. Note that if you want to play around with DECnet at some point, your hostname should be no longer than 6 characters.
ra1 at uq0 slave 1 (RA90) ra2 at uq0 slave 2 (RRD40) ra0 at uq0 slave 0 (RA90) tms0 at uq16 slave 0 (TK50) *** SYSTEM NAME SPECIFICATION *** Select the name of your system using alphanumeric characters. The first character must be a letter. For example, tinker. Enter your system name: yuki You selected yuki as the name of your system. Is this correct? (y/n) [y]: y
Next up is the time configuration. Since Ultrix 4.5 is not Y2k compliant (AFAIK), I decided to set the clock back a whopping 20 years. Note that the timezone and daylight saving settings are for my location (Germany) and will probably vary for you.
*** DATE AND TIME SPECIFICATION ***
The current date and time should be specified using the following
format:
yymmddhhmm
Use two digits for year (yy), month (mm), day (dd), hour (hh), and
minute (mm). Enter the time in 24-hour format. For example, 02:54
p.m. on Feb 2, 1993 would be entered as:
9302021454
Enter the date and time: 9512052336
*** TIME ZONE SELECTION ***
Select the time zone for your area, using the options listed in the
table below. You can also enter the number of hours (-12 to 12) in
time east of Greenwich.
Selection Time Zone

The current date and time is Tue Dec 5 23:36:46 EST 1995
Next up is the root password. Note that Ultrix will not echo anything here, I added the asterisks just for this guide :)
*** SPECIFY THE SUPERUSER PASSWORD *** The Guide to Installing ULTRIX instructs you on how to enter the superuser password. Changing password for root Enter new password: ****** Verify: ******
Next up is the filesystem layout, which is a bit more involved than what you know from more modern systems like MS DOS ;-)
In ULTRIX, partitions are defined for each disk type in a file called /etc/disktab. Note that the partitions overlap, so you shouldn't use them all at the same time. The setup script actually takes care of that for you, but if you later create a new filesystem on the wrong partition you WILL lose data!
Normally, partition c is the whole disk, which is useful for add-on disk drives for example. Partitions a and b are always available and are traditionally used for the system and the swap-space respectively. The swap partition is also used for crashdumps if no separate crash-dump partition is created. The rest of the disk can be used either as a single partition (which is usually g) or as 3 individual partitions (d to f). If the disk is larger than 1 gigabyte, you will get another partition, h, after the g partition, probably because the filesystem cannot cope with partitions >1gig
In our case, we will have the following partitions on the first disk (RA0):
- Partition a of 32 mb for /root
- Partition b of 64 mb for swap+crashdump
- Partition c of 1.2 gig (whole-disk, not used on our setup)
- Partition d and e of 200 mb each (not used)
- Partition f of 400 mb (not used)
- Partition g of 800 mb (overlaps with d, e and f; will become /usr)
- Partition h of 256 mb (will become /usr/var)
This way we still have the whole second disk available for later use.
So here it goes:
*** FILE SYSTEM DEFAULT OPTION ***
The following table shows the default file system layout on RA90, ra0:
partition bottom top size overlap default
a 0 32767 32768 c root
b 32768 159839 127072 c swap, dump
d 159840 580036 420197 c,g /usr
If you choose the defaults, the var area will be allocated to /usr/var.
Do you want to choose the default file system layout? (y/n): n
No, we do not want to use the defaults...
First, we select disk 1, partition g, for the /usr file system:
*** /usr FILE SYSTEM ALLOCATION ***
You can allocate the /usr file system to one of the disks listed in the
table below. See the Guide to Installing ULTRIX for an explanation of
this table:
/usr FILE SYSTEM ALLOCATION TABLE
Selection Device ULTRIX Device Controller Controller
Name Name Number Name Number
----------------------------------------------------------------------
1 RA90 ra0 0 RQDX3 0
2 RA90 ra1 1 RQDX3 0

Enter your choice: 1
You selected RA90, device number 0. Make sure this disk is
on line and write-enabled (if applicable to this drive) and then
confirm your choice.
Use RA90, ra0 for /usr file system? (y/n) []: y
The disk ra0 you selected from the previous table has the following
partitions available, on which you can allocate the /usr file system:

------------------------------------------------
Type the letter of the partition on which you want
to allocate the /usr file system [d]: g
Making the new file system for /usr on /dev/rra0g RA90
Next, we select disk 1, partition b for swap (only 1 swap partition) and for crashdumps:
*** ALLOCATE THE SWAP1 SPACE ***
You can allocate the swap1 space to one of the disks listed in the
table below. See the Guide to Installing ULTRIX for an explanation of
this table:

Type the letter of the partition on which you want
to allocate the swap1 space [b]: b
*** ALLOCATE THE SWAP2 SPACE ***
Do you want to allocate a second swap space? (y/n) [n]: n
*** ALLOCATE THE CRASH DUMP SPACE ***
You can allocate the crash dump space to one of the disks listed in the
table below. See the Guide to Installing ULTRIX for an explanation of
this table:

------------------------------------------------
h --- 267763 c
b --- 63536 c
------------------------------------------------
Type the letter of the partition on which you want
to allocate the crash dump space [b]: b
Finally we select partiton h for the /var file system. This might not be large enough later on but then we can always migrate the data away if we need to...
*** ALLOCATE THE var FILE SYSTEM ***
You can allocate the var file system to one of the disks listed in the
table below. See the Guide to Installing ULTRIX for an explanation of
this table:

Type the letter of the partition on which you want
to allocate the var file system [no default]: h
Making the new file system for var on /dev/rra0h RA90
Installing the distribution files
Next up we have to decide what packages we want to install (yes, ULTRIX already had its own package format and corresponding installer called setld. It is very basic, probably most similar to pkg_add on NetBSD). We simply install everything, since we have enough space :)
This distribution media includes subsets for ULTRIX Worksystem
Software (UWS). A UWS license (on a workstation) or a UWS Server
License (on a timesharing machine or server) is required to install
these subsets.

At some point you will have to confirm installing the generic kernel and the X11 subsystem:
... UWS Runtime Reference Pages (UWSMAN450) Copying from /mnt/VAX/BASE (disk) Verifying UWS Development Reference Pages (UWSMANPGMR450) Copying from /mnt/VAX/BASE (disk) Verifying The installation software has successfully installed the software subsets. Installing Upgrade subsets The following subsets will be installed: * X11/DECwindows Servers Upgrade * Generic Kernel Do you wish to continue? (y/n): y X11/DECwindows Servers Upgrade (UWSSER451) Copying from /mnt/VAX/BASE_UPGRADE (disk) Verifying Generic Kernel (ULTGENVMUNIX451) Copying from /mnt/VAX/BASE_UPGRADE (disk) Verifying The installation procedure has successfully installed the Upgrade subsets
That's it for the base installation, now we configure our kernel...
Kernel configuration
We have to select what features will be in the kernel. For anyone who has ever done a "make menuconfig" on Linux, this is slightly easier here ;-)
*** CONFIGURATION FILE KERNEL OPTION SELECTION ***
Selection Kernel Option
---------------------------------------------------------------
1 Local Area Transport (LAT)
2 Bisynchronous Communication protocol (VAX only)
3 Computer Interconnect (CI) network
4 Diagnostic/Utilities Protocol (DUP)
5 ISO9660 File System Support (CDFS)
6 Ethernet Packet Filter
7 Enhanced Security Features
8 All of the above
9 None of the above
----------------------------------------------------------------
Enter the selection number for each kernel option you want.
For example, 1 3 :
In our case, we don't need 2 (it is for 2780/3780 remote terminals), 3 (SimH doesn't emulate any cluster hardware) or 6 (it might cause problems with DECwindows/Motif). Everything else (1 4 5 7) is probably safe. This lets us play around with LAT (maybe connect an emulated Cisco router with LAT routing to it?) and DUP.
Enter the selection number for each kernel option you want.
For example, 1 3 : 1 4 5 7
You specified the following kernel options:
Local Area Transport (LAT)
Diagnostic/Utilities Protocol (DUP)
ISO9660 File System Support (CDFS)
Enhanced Security Features

Now you might want to take another backup of your disk images, since the ULTRIX installation is now basically complete.
Adding the unsupported sets
Now there are some more pieces of software in the CDROM, in a directory called unsupported. We want to install these as well. First, let's boot our system again

Note that you could also quickly install only a single package by using for example

After a few minutes, installation will be completed and we should unmount the CDROM
# cd / # umount /mnt
Network configuration
To configure the network, you have to use a static IPv4 address and put that into the beginning of /etc/rc.local. Note that there is no ifconfig -a in ULTRIX, you have to use netstat -i
# netstat -i Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll qe0* 1500 none none 0 0 0 0 0 lo0 1536 loop localhost 1 0 1 0 0 # ifconfig qe0 192.168.1.44 netmask 255.255.255.0 up # route add default 192.168.1.1 1 add net default: gateway 192.168.1.1 # ping 192.168.1.1 192.168.1.1 is alive
Note that it might actually take a while until packets are getting through. I don't know why but in my case it helped to ping ULTRIX from the outside first, e.g. from Windows, and then re-try the ping from the VM. Then it worked. I'm guessing this is some SimH/Windows issue with PCAP or something.
Then put these 2 commands at the start of /etc/rc.local (you'll see where). Note that you can use vi now!
# @(#)rc.local 9.4 (ULTRIX) 9/21/95 /bin/hostname yuki #/etc/ifconfig HDWR `/bin/hostname` broadcast NETNUM.0 netmask 255.0 /etc/ifconfig qe0 192.168.1.44 netmask 255.255.255.0 route add default 192.168.1.1 1 /etc/ifconfig lo0 localhost #/etc/bscconfig dup0 bsc 1 #/etc/bscconfig dpv0 bsc 1 ...
Note that DNS lookups normally don't work out of the box. Create a basic /etc/resolv.conf file with the following content (or whatever is correct in your environment)
domain lan.local nameserver 192.168.1.1
However, if you then try to do an nslookup query, you will get an error message
# nslookup www.google.com *** Can't find server name for address 192.168.1.1: Not implemented *** Default servers are not available
The problem is that ULTRIX sends so-called inverse queries (not to be confused with the well-known reverse lookups, which are actually just regular forward lookups to a specific TLD) to map IP addresses to hostnames. Most DNS servers don't support these inverse queries anymore. Apparently, BIND8 still included an option "fake-iquery" which might be used to support these queries. Versions before BIND8 (4.x) supported IQUERY natively. I have yet to test both variants to see which (if any) of them work.
Shutting down cleanly
As you'd expect, you can use shutdown to shut the system down
# shutdown -h now

Enabling outside access
The SimH config above includes a 16-line serial multiplexer. If you connect via TELNET to port 1005, you are given the first free serial line of the emulated DZ device. However, serial login is disabled by default, so it has to be enabled first. That's what the /etc/ttys file is for. Edit the file and change the off to on in the lines for tty00 to tty07, as shown below
# @(#)ttys 9.1 (ULTRIX) 4/26/94 # # # # name getty type status comments # console "/etc/getty std.9600" vt100 on secure # console terminal tty00 "/etc/getty std.9600" vt100 on nomodem # direct connect tty tty01 "/etc/getty std.9600" vt100 on nomodem # direct connect tty tty02 "/etc/getty std.9600" vt100 on nomodem # direct connect tty tty03 "/etc/getty std.9600" vt100 on nomodem # direct connect tty tty04 "/etc/getty std.9600" vt100 on nomodem # direct connect tty tty05 "/etc/getty std.9600" vt100 on nomodem # direct connect tty tty06 "/etc/getty std.9600" vt100 on nomodem # direct connect tty tty07 "/etc/getty std.9600" vt100 on nomodem # direct connect tty ttyd0 "/etc/getty std.9600" vt100 off shared secure # modem line
If you want to be able to login as root on these terminals, you can also add the secure flag as well. Also note that while it seems tempting to increase the line speed to 19200 or even higher, from my experience that will cause massive lags and emulation hangs in SimH, so do that on your own risk.
After editing the file and saving it, you have to reload init:
# kill -HUP 1
Now try logging in to port 1005 via telnet, and you should be greeted with this:
Connected to the MicroVAX 3900 simulator DZ device, line 0 ULTRIX V4.5 (Rev. 47) (yuki) login: root Password: Requires secure terminal
Note that SimH will print out the serial line to which you are connected, in this case line 0 which is /dev/tty00.
Also, if your inetd is running (which it should be, if you followed this guide), you will also already be able to login remotely using telnet.
ULTRIX V4.5 (Rev. 47) (yuki) login: root Password: Requires secure terminal
To enable root access for all telnet sessions, you will have to edit the /etc/ttys file and change every line that starts with "ttyp" to include the secure flag:
ttyp0 none network
will become
ttyp0 none network secure
and so on...
