Ninth Edition Unix System for Sun3
Copyright (C) AT&T 1989. All Rights Reserved

This directory contains the source for the Ninth Edition(v9) system
that was ported to the Sun.  The source was derived from a snapshot of the
VAX v9 system, sometime around the beginning of 1987.  It has
not been updated to incorporate changes that have been made
to the v9 system since then.

In addition to the source, the binaries for a a Sun 3/75 or
3/50 with a SCSI disk drive are included.  A system may be built
very quickly by booting the Sun diskless from a Sun server, building
the v9 file system on the raw device, and then rebooting from the
v9 system on the disk drive.

An overview of the directories is given below:

	X11 - contains the X11 release 1 code that runs under v9
	on the Sun.  It does some things unconventionally.  For example
	the keyboard and mouse line disciplines are part of the X11
	server, instead of the operating system.  The server just
	reads the serial ports directly, with no operating system
	intervention.

	cmd - source for all the commands.

	include - v9 include files for the Sun

	ipc - interprocess communications source, including dialers
	and source for ipc libraries.

	jerq - 5620 software, only a small subset is included and
	was ever tested.  Once X windows was working, this directory
	was essentially discarded.

	jtools - copy of 5620 tools that were ported to run under X11.
	This includes things like Rob Pike's editor sam, Tom Cargill's pi,
	mux style terminal windows and a bunch of other goodies.  The
	5620 emulator library and associated tools can also be compiled
	to run on a Sun under SunOS (under either X11 or Sunview).

	libc - C library source
	libtermlib - terminal cursor control library

	netb - network file system code for mounting filesystems
	of remote machines.  Unlike NFS, it mounts the whole machine
	and maps users between systems.  Netb contains the server code
	while the netb driver in the kernel provides the client code.
	The server code will run on either a v9 or BSD machine.

	sys - the v9 kernel code.  Directories that end in .old
	contain the original VAX v9 code the files were derived from.
	These were kept around to make it possible to diff them from
	and upgrades made to the VAX v9 system.  The directory
	sys/construct contains the working binaries that can be
	used to construct without all the normal bootstrapping problems.

Notes: 1)all the source and makefiles(mkfiles), except for a few
	in the sys/construct directory, assume they are being
	compiled on a running v9 system.  If you are going to X-compile
	them under SunOS, some tweaking of the makefiles and compiler front
	end may be necessary.

	2)the compiler used by the v9 system generates symbol table
	entries in the format of the v9 VAX compiler (rather than the
	SUN format). When the v9 system was ported, it was simpler to
	change the compiler than to backwards engineer a parser for
	Suns yuckky symbol table (i.e. for use with pi).  Since then,
	I have written a Sun format symbol table parser so pi can be
	used under SunOS.  If I were going to do it over, I would not
	modify the compiler.

	3)the v9 tar is slightly different than the BSD tar. It handles
	and stores symbolic links differently.  Many of the binaries in
	sys/construct/test are in v9 format tar files.  If you want to
	unpack them on a Sun under SunOS, there is a copy of the v9 tar
	that runs under SunOS release 4.0 in sys/construct/host/v9tar.c.
	By default, the v9 tar follows symbolic links when making tar files.
	Use the L option to put the symbolic link in the tar file instead of
	what the link points to.

BOOTSTRAPPING:
Assuming your goal is to get a system running as soon as possible,
the following is a short cookbook that should generate a standalone
v9 system with minimal effort (provided you have a 3/50 or 3/75 with
a SCSI disk drive):

     1) Install this source on a Sun server running SunOS
	If you are reading this, you already did that.
     2) Format and label the SCSI disk you will install the system on using
	the tools provided by Sun (diag, format). On SunOS release 4.0 you
	can do it with format while the system is running Unix. Previous
	releases required running diag in a stand-alone mode.  Write down
	the number of 512-byte blocks in the partitions you wish to make file
	systems on.  I usually put the root file system on partition a and the
	usr file system on parition g.  If the drive has already been
	paritioned you can discover the number of block with the SunOS
	dkinfo command.
     3) Boot up the system you want to install the v9 system on, under SunOS
	from the server.  Make sure the disk driver is in the SunOS kernel.  
     4) Build SunOS versions of the v9 tools to construct file systems on
	disks (fsck, mkfs) with the following commands:
		cd sys/construct/host
		make fsck mkfs
		mv fsck mkfs ..
		cd ..
	The goal is to use these commands to install a complete v9 system
	on the clean disk, using SunOS to do the installation.
     5) Edit the disk building proto files in sys/construct.  These proto
	files, used by mkfs, construct a new file system and initialize it
	with a list of files, directories, etc.  Four proto files are
	already in the directory.  Files of the form proto0a.* are for
	building the root file system and files of the form proto0g.* are
	for the user file system.  The two that are there have the right
	numbers for a CDC 155M Wren III drive and a CDC 300M Wren IV
	(suffixes .cdc and .w4 respectively).  In the proto0a file,
	only two lines need to be edited: the second line and the next
	to last line.  The second line contains the number of 8K blocks
	in the file system, followed by the number of inodes in the file
	system.  These numbers have to be adjusted to match the size of
	the file system.  The first number can be calculated by dividing
	the number of 512byte blocks recorded in step 2 by 16.  The second
	number can be retrieved from mkfs by invoking it without a proto
	file.  For example, if the file system /dev/rsd0a has 2000 8K blocks,
	running the command (must be su):
		mkfs /dev/rsd0a 2000
	will print something like:
		isize = 12416
		m/n = 3 1000
	and then build a file system. You can kill it after the lines are
	printed as you don't actually need to build the file system yet.
	The value of isize should be moved to the second value on the second
	line of the proto file.
	The last to next line of proto0a.* determines where the unix kernel
	binary is taken from.  If the system is a Sun 3/50 the line should
	read:
		unix		---755 0 4 test/unix.50
	while for a Sun 3/75 it should be:
		unix		---755 0 4 test/unix.75.
	In the /usr proto file, proto0g.*, only the second line, containing
	the number of blocks + inodes needs to be modified.
     6) The binaries to construct a system are in sys/construct/test.
	Some of these files need to be edited to match your site and
	configuration.  The only one that needs modification is etc/rc.
	Look for the line with "ipconfig" in it.  If the system is a
	3-75, the line should be (Intel Ethernet chips):
/usr/ipc/mgrs/ipconfig /dev/ie00 `cat /etc/whoami` mh-capek-net /dev/ie01 &
	while for a 3-50 it should be: (AMD Lance Ethernet chips):
/usr/ipc/mgrs/ipconfig /dev/le00 `cat /etc/whoami` mh-capek-net /dev/le01 &

	Other files that you probably want to modify are:
		etc/passwd
		etc/whoami - should contain name of the system
     7) You are now ready to build the file systems:
		cd sys/construct
		mkfs /dev/rsd0a proto0a.new
		mkfs /dev/rsd0g proto0g.new
     8) I would check them after you make them with fsck.
		fsck /dev/rsd0a /dev/rsd0g
	Expect fsck to complain:
		file is not a block or character device; OK?
	when it starts up, as it is compiled with v9's idea of
	a file system, not SunOS'.  Just type "y".  If there are
	any other problems, something went wrong making the file systems.
     9) Install the boot block on /dev/rsd0a (since the file systems have
	a different format, a new boot block must also be installed):
		cd test/stand
		installboot bootpr /dev/rsd0a
		cd ../..
    10) You are now ready to boot the v9 system.  Halt SunOS and boot
	the v9 system in single user mode (it is IMPORTANT that you
	bring it up single user when first booting):
		b sd(0,0,0) -s
    11) It should print out the configuration info and then give you
	the # prompt.  Congratulations, you are now running under
	Ninth Edition.
    12) Finish the installation procedure by executing the shell file
	"startup" in the root directory:
		cd /
		startup	
	This file takes care of unpacking all the tar files used to
	construct the system.  It will run for several minutes as many of
	the tar files have been compressed to save space.
	You can see what it does by looking at it before you build
	the system (sys/construct/test/startup).
    13) Give root a passwd
    14) Edit the Ethernet host and authentication tables in /usr/ipc/lib.
	The files of interest are
		inaddr.local
		auth.local
	to correspond to your site.  The format of the files should be
	obvious from looking at them.
    15) Type control-D to bring the system up multiuser.
    16) Log in as root and give yourself a login
    17) Log in as yourself. To use the X window system, copy the
	following files from the /usr/dak directory:
		.profile	/* For correct PATH */
		.Xstart		/* X startup file */
		.uwmrc
	To start the X window system:
		. .profile
		Xstart
	To get out of the X window system, type Xexit in any of the windows.
	The window manager is configure so holding down the Sun keyboard
	"LEFT" or "RIGHT" key and hitting the right mouse button generates
	the window manager menu.
    19) After the system has been installed, future boots should be
	automatic.  Just power up or type >b sd() to the console monitor.
    20) Good luck

If your are going to build your own system, you will need to build the
v9 config (sys/conf/src/config) first.  There is a man page in that
directory describing it. The configuration files themselves, look
very similar to the configuration files used by Sun to build their kernels.
See sys/{3-50|3-75}/conf for examples.

Some known bugs (I'm sure there are more):
	The keyboard line discipline that the kernel pops on the console
	(sys/sundev/kbdld.c) to map up-down keystrokes of the Sun keyboard
	to ASCII characters is buggy.  This discipline is only used when using 	the PROM to drive the screen (i.e. when not using a window system).
	The problem is the discipline believes it will get
	an up/down sequence for each key hit.  Unfortunately, Sun
	keyboads don't generate up/down codes like they are supposed to.
	Sometimes the up or down sequence never gets transmitted.
	The fix that Sun uses in their driver keeps a table containing
	the state of each key, so if for example an up code for a key
	is received but the driver thinks the key is already up, the
	driver fakes the down code when it receives the up code.
	If you have noticed that when you type quickly to a Sun
	characters get transposed with a higher frequency than normal,
	this is the reason.  The driver in the X11 server keeps a
	a state map of the keys and generates the fake codes.
	The symptom you will see when not using X windows, is typed
	characters on the console will be lost.

	The SCSI tape driver is not compatible with the drives shipped
	by Sun.  It works with the ARCHIVE Corporation Viper (2060S)
	Half-Height Intelligent SCSI driver (the controller is built
	in the drive).

	The SCSI disconned/reconnect doesn't work.  It didn't work in
	the SunOS release 3.1 drivers, from which the SCSI driver is
	derived, either.
