This is the procedure is copied from [http://zazie.tom-yam.or.jp/starunix/4.0bsd/4.0bsd.html tom yam] to install 4.0 BSD onto [[SIMH]]'s [[VAX 11/780]] emulator.

== Requirements ==
* You will need a working copy of SIMH's vax780.exe for your platform.
* A 4.0 BSD install tape. You can download one from [http://sourceforge.net/projects/bsd42/files/Install%20tapes/4.0%20BSD/4.0bsd.tap.bz2/download sourceforge]
* A copy of [[bzip2]] to decompress the tape image

		+	Simply boot up from tape by invoking SIMH's VAX 11/780 with the tape boot ini as follows:

		+	<pre>

		+	C:\bsd40>vax780.exe tboot.ini
		+
		+	VAX780 simulator V3.8-1
		+	RP: creating new file
		+	Overwrite last track? [N] y
		+
		+	HALT instruction, PC: 00050033 (HALT)
		+	=
		+	</pre>
		+
		+	This will get you to the bootloader which we can then use to invoke the mkfs/restore commands. There isn't any need to lowlevel format in the emulator.
		+
		+	<pre>
		+	=mkfs
		+	file sys size: 7942
		+	file system: hp(0,0)
		+	isize = 5072
		+	m/n = 3 500
		+	=
		+	</pre>
		+
		+	Now to restore the root/boot partition:
		+
		+	<pre>
		+	Tape? ht(0,1)
		+	Disk? hp(0,0)
		+	Last chance before scribbling on disk.
		+	End of tape
		+	=
		+	</pre>
		+
		+	Hit enter when prompted "Last chance before scribbling on disk.".
		+
		+	Now we can invoke the boot program to load up the kernel so we can continue the install.
		+	<pre>
		+	=boot
		+
		+	Boot
		+	:
		+	</pre>
		+
		+	Now we can specify the disk & kernel, as follows:

		+	WARNING: preposterous time in file system -- CHECK AND RESET THE DATE!
		+	ERASE IS CONTROL-H!!!
		+	#

		+
		+	It is recommended that you run fsck to ensure that the 'a' partition is in good health. Run fsck as follows:
		+
		+	<pre>
		+	# fsck /dev/rrp0a

		+	The first step is to decompress the tape image with bzip2. This should be very straightforward:
