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
1.9 ! wilfried 26: disk image and the <i>floppy39.fs</i> from your CD-ROM set.
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
65: corresponding to your real CD-ROM unit. See the SIMH documentation
66: for more details.

1.1 kettenis 71: OpenBSD/vax SIMH environment. Unmount CD1, but leave it in the CD-ROM
72: unit.
73:
74: Now fire up SIMH. At the boot prompt you should type <strong>boot
75: dua2:</strong>, after which SIMH should boot into the normal OpenBSD
76: installation program:
