! 23: It is very easy to install OpenBSD/vax on the
! 24: <a href="http://simh.trailing-edge.com">SIMH<a> VAX simulator. All
! 25: you need is a reasonably fast machine, enough disk space for a 1.5GB
! 26: disk image and the <i>floppy36.fs</i> from your CD-ROM set.
! 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:
! 33:
! 34: <ul><pre>
! 35: <strong>
! 36: set cpu 64m
! 37: at nvr openbsd.nvram
! 38:
! 39: deposit rq qtime 100
! 40:
! 41: set rq0 ra92
! 42: at rq0 openbsd.ra0.disk
! 43:
! 44: set rq1 cdrom
! 45: at rq1 /dev/rcd0c
! 46:
! 47: set rq2 cdrom
! 48: at rq2 floppy36.fs
! 49:
! 50: at xq0 bge0
! 51:
! 52: boot cpu
! 53: exit
! 54: </strong>
! 55: </pre></ul>
! 56:
! 57: This configures SIMH to simulate a VAX with a whopping 64 MB of
! 58: memory, a RA92 1.5GB disk, a CD-ROM unit to hold CD1 of your CD-ROM
! 59: set, another CD-ROM unit to boot from, and a DELQA Qbus Ethernet
! 60: controller. You'll need to replace <strong>bge0</strong> with the
! 61: name of the network interface in your machine. You also might need to
! 62: replace <strong>/dev/rcd0c</strong> with the name of the raw device
! 63: corresponding to your real CD-ROM unit. See the SIMH documentation
! 64: for more details.
! 65:
! 66: <p>
! 67:
! 68: Copy <i>CD1:3.6/vax/floppy36.fs</i> to the location of your
! 69: OpenBSD/vax SIMH environment. Unmount CD1, but leave it in the CD-ROM
! 70: unit.
! 71:
! 72: Now fire up SIMH. At the boot prompt you should type <strong>boot
! 73: dua2:</strong>, after which SIMH should boot into the normal OpenBSD
! 74: installation program:
! 75:
! 76: <ul><pre>
! 77: # <strong>simh-vax openbsd.simh</strong>
! 78:
! 79: VAX simulator V3.0-2

! 103: > boot bsd
! 104: </pre></ul>
! 105:
! 106: After you've finished the installation, restart SIMH, but now type:
! 107:
! 108: <ul><pre>
! 109: >>><strong>boot dua0:</strong>
! 110: </pre></ul>
! 111:
! 112: to boot from your newly installed disk image. You'll need a little
! 113: patience upon your first boot, since generating the SSH host keys can
! 114: take quite a bit of time. But it will eventually boot through and
! 115: present you with a friendly login prompt:
! 116:
! 117: <ul><pre>
! 118: OpenBSD/vax (noname.my.domain) (console)
! 119:
! 120: login:
! 121: </pre></ul>
! 122:
! 123: When you are done installing any additional packages, you might want
! 124: to remove the lines referring to your real CD-ROM unit and
! 125: <i>floppy36.fs</i> from your <i>openbsd.simh</i> file.
! 126:
! 127: <p>

! 129: Enjoy!
