Booting a real MicroVAX 2000 from an ULTRIX V3.0 DMS Server on a SIMH MicroVAX 3900
Items needed
- A real MicroVAX 2000 or VAXstation 2000
- A SIMH MicroVAX 3900 set up according to page "Installing and Configuring an ULTRIX V3.0 DMS Server on a SIMH MicroVAX 3900"
- An Ethernet Repeater with BNC and Twisted-Pair ports
Adding your MicroVAX 2000 / VAXstation 2000 as an ULTRIX DMS Client
Follow this instructions on the SIMH MicroVAX 3900 to add your MicroVAX 2000 / VAXstation 2000 as an ULTRIX DMS client.
Answer the question:
Select the processor type for this client:
with your type of VAX.
Connections needed
Ethernet connection
I use an old Ethernet Repeater (often called "Hub").
It is a "MicroHub/8 TP1008C" with eight Twisted-Pair ports and one BNC port.
Devices like this still show up at ebay from time to time.
Connect your PC running SIMH to a Twisted-Pair port and your MicroVAX 2000 / VAXstation 2000 to the BNC port.
Make sure to use BNC T-connectors at both ends of the coaxial cable and terminate both unused T-connector ports with 50 Ohm terminator plugs:

MicroVAX 2000 console terminal connection
- Connect a real VT terminal (if you have got one) to your MicroVAX 2000 / VAXstation 2000 console port.
or:
- Use PuTTY (if your PC has got no more Serial adapter, use a USB-to-Serial adapter) to connect to your MicroVAX 2000 / VAXstation 2000 console port.
As for the MicroVAX 2000 / VAXstation 2000 console port, see VS2000 hardware info page

Startup and Selftest
This is how my MicroVAX 2000 (rather a VAXstation 2000 switched to a MicroVAX 2000) starts up:
KA410-B V2.2 F_..E...D...C...B...A...9...8...7...6...5...4...3_..2_..1... ? E 0040 0000.0045 ? D 0050 0000.0005 ? C 0080 0000.4001 ? 6 00A0 0000.4001
A single question mark (?) means "something special", a double question mark (??) means a hard fault.
- ? E => System clock (has no battery)
- ? D => Nonvolatile RAM (is empty because of no battery)
- ? C => Serial line controller (unknown terminal connected [PuTTY])
- ? 6 => Tape controller option (no tape controller)
Your MicroVAX 2000 / VAXstation 2000 might respond differently; see the following table for the meaning of the device identifiers:
Identifier | Device |
F | Base video |
E | System clock |
D | Nonvolatile RAM |
C | Serial line controller |
B | Memory |
A | Memory-management unit |
9 | Floating point unit |
8 | Interval timer |
7 | Disk controller option |
6 | Tape controller option |
5 | Interrupt controller and Ethernet ID ROM |
4 | Optional 8-plane graphics coprocessor |
3 | Reserved for later use |
2 | Reserved for later use |
1 | Ethernet network interconnect (NI) |
Booting the MicroVAX 2000 / VAXstation 2000
If your MicroVAX 2000 / VAXstation 2000 has no battery (as mine), it will try to boot automatically.
If it has got a battery, it will do whatever is stored in the non-volatile RAM.
If you get the chevrons prompt (>>>), type BOOT ESA0, if you enter BOOT only, it will try to boot from its disk (if present), first.
