23: It is very easy to install OpenBSD/vax on the
1.2 henning 24: <a href="http://simh.trailing-edge.com">SIMH</a> VAX simulator. All
1.1 kettenis 25: you need is a reasonably fast machine, enough disk space for a 1.5GB
1.16 ! sthen 26: disk image and the vax <i>floppy46.fs</i> file.
1.1 kettenis 27:
28: Assuming you're going to run SIMH on an OpenBSD system, install the
29: <i>emulators/simh</i> package from <a href="ports.html">ports</a>.
30: Decide on an appropriate location for your OpenBSD/vax SIMH
31: environment and at that location, create a file <i>openbsd.simh</i>
32: with the following contents:

59: This configures SIMH to simulate a VAX with a whopping 64 MB of
60: memory, a RA92 1.5GB disk, a CD-ROM unit to hold CD1 of your CD-ROM
61: set, another CD-ROM unit to boot from, and a DELQA Qbus Ethernet
62: controller. You'll need to replace <strong>bge0</strong> with the
63: name of the network interface in your machine. You also might need to
64: replace <strong>/dev/rcd0c</strong> with the name of the raw device
1.15 sthen 65: corresponding to your real CD-ROM unit. By default pressing ^E
66: will interrupt the emulation; if you're accustomed to the emacs
67: editing keys, you might like to remap this (e.g. adding <strong>set
68: console wru=1e</strong> sets it to ^6, ascii code 0x1e). See the
69: SIMH documentation for more details.
