NetBSD SIMH HOW-TO
This guide is intended to help you install NetBSD on the SIMH VAX emulator.
     1.	   Install the simulator from SIMH home page. There is a package available to make life simple.
     2.	   Get a NetBSD/vax CD ISO image, for example NetBSD 2.0.
     3.	   Start the emulator program (/usr/pkg/bin/simh-vax).
     4.	   At the emulator prompt, type
     5.		load -r ka655.bin
     6.		set cpu 64m
     7.		set rq0 ra92
     8.		at rq0 netbsd.dsk
     9.		set rq1 cdrom
     10.	at rq1 /path/to/vaxcd.iso
		set xq mac=00-17-F2-43-45-50
     11.	at xq en1
     12.	boot cpu
     13.  This will configure the emulated VAX with an RA92 disk (/dev/ra0*), and the CD image masquerading as an RD54 disk (/dev/ra1*). See the SIMH documentation for other options.
     14.  At the VMB prompt, type
     15.        boot dua1:
     16.  to boot off the CD.
     17.  Proceed with a normal NetBSD install. You may not want to install the X11 stuff, since SIMH doesn't emulate a frame buffer. Once the install program prompts you to mount the CD drive and defaults to /dev/cd0a you should change this to /dev/ra1a.
     18.  After a considerable amount of time, the installation finishes, and you may shut down or reboot.
     19.  You can now type q at the emulator prompt to exit the emulator.
     20.  Enter these lines
     21.        load -r /usr/pkg/share/simh/ka655.bin
     22.        set cpu 64m
     23.        set rq0 ra92
     24.        at rq0 netbsd.dsk
     25.        at xq0 name-of-network-interface-on-host
     26.        boot cpu
     27.  into a file, say netbsd-boot.
     28.  Restart the emulator like so:
     29.        /usr/pkg/bin/simh-vax netbsd-boot
     30.  At the VMB prompt, type
     31.        boot dua0:
     32.  to boot off the disk.
     33.  Welcome to NetBSD!
