dnl ========== Various Install Instructions
dnl (usually used by arch/install)
dnl
dnl Short or longer installation introduction. The longer version warns
dnl about disk geometry hell.
define({:-OpenBSDInstallShortPrelude-:},
{:-Installing OpenBSD is a relatively complex process, but if you have
this document in hand and are careful to read and remember the
information which is presented to you by the install program, it
shouldn't be too much trouble.-:})dnl
dnl
define({:-OpenBSDInstallPrelude-:},
{:-OpenBSDInstallShortPrelude

Before you begin, you should know the geometry of your hard disk, i.e.
the sector size (note that sector sizes other than 512 bytes are not
currently supported), the number of sectors per track, the number of
tracks per cylinder (also known as the number of heads), and the
number of cylinders on the disk.  The OpenBSD kernel will try to
discover these parameters on its own, and if it can it will print them
at boot time.  If possible, you should use the parameters it prints.
(You might not be able to because you're sharing your disk with
another operating system, or because your disk is old enough that the
kernel can't figure out its geometry.)-:})dnl
dnl
dnl OpenBSDInstallPart2
dnl Describes the beginning of the installation process, once the
dnl installation media is ready.
define({:-OpenBSDInstallPart2-:},
{:-You should now be ready to install OpenBSD.

The following is a walk-through of the steps you will take while
getting OpenBSD installed on your hard disk.  If any question has a
default answer, it will be displayed in brackets ("[]") after the  
question.  If you wish to stop the installation, you may hit Control-C
at any time, but if you do, you'll have to begin the installation
process again from scratch.  Using Control-Z to suspend the process
may be a better option, or at any prompt enter '!' to get a shell,
from which 'exit' will return you back to that prompt (no refresh
of the prompt though).-:})dnl
dnl
dnl OpenBSDBootMsgs
dnl Describes the boot of the ramdisk.
define({:-OpenBSDBootMsgs-:},
{:-	Once the kernel has loaded, you will be presented with the
	OpenBSD kernel boot messages.  You will want to read them
	to determine your disk's name and geometry.  Its name will
	be something like "sd0" or "wd0" and the geometry will be
	printed on a line that begins with its name.  As mentioned
	above, you will need your disk's geometry when creating
	OpenBSD partitions.  You will also need to know the device
	name to tell the install tools what disk to install on. If
	you cannot read the messages as they scroll by, do not
	worry -- you can get at this information later inside the
	install program.-:})dnl
dnl
dnl Notes for various installation methods.
dnl
define({:-OpenBSDFTPInstall-:},
{:-	To install via FTP:
		To begin an FTP install you will need the following
		pieces of information.  Don't be daunted by this list;
		the defaults are sufficient for most people.
		    1) Proxy server URL if you are using a URL-based
		       ftp proxy (squid, CERN ftp, Apache 1.2 or higher).
		       You need to {:-define-:} a proxy if you are behind a
		       firewall that blocks outgoing ftp (assuming you
		       have a proxy available to use).
		    2) Do you need to use active mode ftp?  By default,
		       ftp will attempt to use passive mode and fall
		       back to an active connection if the server does
		       not support passive mode.  You only need to enable
		       this option if you are connecting to a buggy ftp
		       daemon that implements passive ftp incorrectly.
		       Note that you will not be asked about active
		       ftp if you are using a proxy.
		    3) The IP address (or hostname if you enabled
		       DNS earlier in the install) of an ftp server
		       carrying the OpenBSD OSREV distribution.
		       If you don't know, just hit return when
		       asked if you want to see a list of such hosts.
		    4) The ftp directory holding the distribution sets.
		       The default value of pub/OpenBSD/OSREV/MACHINE
		       is almost always correct.
		    5) The login and password for the ftp account.
		       You will only be asked for a password for
		       non-anonymous ftp.

		For instructions on how to complete the installation via
		ftp, see the section named "Common URL installations" below.-:})dnl
dnl
define({:-OpenBSDHTTPInstall-:},
{:-	To install via HTTP:
		To begin an HTTP install you will need the following
		pieces of information:
		    1) Proxy server URL if you are using a URL-based
		       http proxy (squid, CERN ftp, Apache 1.2 or higher).
		       You need to {:-define-:} a proxy if you are behind a
		       firewall that blocks outgoing http connections
		       (assuming you have a proxy available to use).
		    2) The IP address (or hostname if you enabled
		       DNS earlier in the install) of an http server
		       carrying the OpenBSD OSREV distribution.
		       If you don't know, just hit return when
		       asked if you want to see a list of such hosts.
		    3) The directory holding the distribution sets.
		       There is no standard location for this;
		       You should use the directory specified
		       along with the server in the list of official
		       http mirror sites that you received in step 3.

		For instructions on how to complete the installation via
		http, see the section named "Common URL installations" below.-:})dnl

dnl For arches where you can create a boot tape, $1 can be set as the
dnl file index of the first set, after the boot files.
define({:-OpenBSDTAPEInstall-:},
{:-	To install from tape:
		In order to install from tape, the distribution sets to be
		installed must have been written to tape previously, either
		in tar format or gzip-compressed tar format.

		You will also have to identify the tape device where the
		distribution sets are to be extracted from.  This will
		typically be "nrst0" (no-rewind, raw interface).

		Next you will have to provide the file number of the set
		that is to be extracted.  Note that the file number starts
		at 1, which is the first file written to the tape{:--:}ifelse(X$1,X,,{:-, unless
		you have created a bootable tape, in which case the file
		number starts at $1-:}).

		The install program will not automatically detect whether
		an image has been compressed, so it will ask for that
		information before starting the extraction.-:})dnl
dnl
define({:-OpenBSDCDROMInstall-:},
{:-	To install from CD-ROM:
		When installing from a CD-ROM, you will be asked which
		device holds the distribution sets.  This will typically
		be "cd0".  Next you will be asked which partition on the
		CD-ROM the distribution is to be loaded from.  This is
		normally partition "a".

		Next you will have to identify the file system type that
		has been used to create the distribution on the CD-ROM,
		this can be either FFS or ISO CD9660.  The OpenBSD CD
		distribution uses the CD9660 format.

		You will also have to provide the relative path to the
		directory on the CD which holds the distribution, for the
		MACHINE this is "OSREV/MACHINE".

		For instructions on how to complete the installation from
		the CD-ROM distribution, see the section named "Common
		file system installations" below.-:})dnl
dnl
define({:-OpenBSDNFSInstall-:},
{:-	To install from a NFS mounted directory:
		When installing from a NFS-mounted directory, you must
		have completed network configuration above, and also
		set up the exported file system on the NFS server in
		advance.

		First you must identify the IP address of the NFS server
		to load the distribution from, and the file system the
		server expects you to mount.

		The install program will also ask whether or not TCP
		should be used for transport (the default is UDP).  Note
		that TCP only works with newer NFS servers.

		You will also have to provide the relative path to the
		directory on the file system where the distribution sets
		are located.  Note that this path should not be prefixed
		with a '/'.

		For instructions on how to complete the installation from
		the CD-ROM distribution, see the section named "Common
		file system installations" below.-:})dnl

define({:-OpenBSDDISKInstall-:},
{:-	To install from a local disk partition:
		When installing from a local disk partition, you will
		first have to identify which disk holds the distribution
		sets.  This is normally $1"sdN" where N is a number
		0 through 9.  Next you will have to identify the partition
		within that disk that holds the distribution, this is a
		single letter between 'a' and 'p'.

		You will also have to identify the type of file system

		$2{:--:}install from partitions that has been formatted as the
		Berkeley fast file system (ffs)$3.

		You will also have to provide the relative path to the

		For instructions on how to complete the installation from
		the a local disk partition, see the next section.-:})dnl
dnl
define({:-OpenBSDCommonFS-:},
{:-	Common file system installations:
		The following instructions are common to installations
		from local disk partitions, NFS mounted directories and
		CD-ROMs.

		A list of available distribution sets will be listed.
		You may individually select distribution sets to install
		or enter `all' to install all of the sets (which is what

		a file name, e.g. `*.tgz' or even `base*|comp*'.  It is
		also possible to enter an arbitrary filename and have it
		treated as a file set.

		Once you have selected the file sets you want to install
		and entered `done' you will be prompted to verify that
		you really do want to extract file sets.  Assuming you
		acquiesce, the files will begin to extract.  If not, you
		will be given the option of installing sets via one of
		the other install methods.-:})dnl
dnl
define({:-OpenBSDCommonURL-:},
{:-	Common URL installations:
		Once you have entered the required information, the
		install program will fetch a file list and present
		a list of all the distribution sets that were found
		in the specified directory.  (If no valid sets were found,
		you will be notified and given the option of unpacking
		any gzipped tar files found or getting a file list if
		none were found.)

		At this point you may individually select distribution
		sets to install or enter `all' to install all of the
		sets (which is what most users will want to do).  You
		may also enter `list' to get a file list or `done' when
		you are done selecting distribution sets.  You may also
		use wildcards in place of a file name, e.g. `*.tgz' or

The upgrade script will ask you for the existing root partition, and
will use the existing filesystems defined in /etc/fstab to install the
new system in.  It will also use your existing network parameters.

From then, the upgrade procedure is very close to the installation
procedure described earlier in this document.  Note that the upgrade
procedure will not let you pick the ``etc{:--:}OSrev.tgz'' set, so as to
preserve your files in `/etc' which you are likely to have customized
since a previous installation.

dnl Various floppy generation instructions.
dnl
define({:-OpenBSDXferFloppyFromDOS-:},
{:-Creating a bootable floppy disk using DOS/Windows:

	First you need to get access to the OpenBSD bootable floppy
	images. If you can access the distribution from the CD-ROM under 
	DOS, you will find the bootable disks in the OSREV/MACHINE 
	directory. Otherwise, you will have to download them from one of 
	the OpenBSD ftp or http mirror sites, using an ftp client or a web 
	browser. In either case, take care to do "binary" transfers, since 
	these are images files and any DOS cr/lf translations or control/z 
	EOF interpretations will result in corrupted transfers.
	
	You will also need to go to the "tools" directory and grab a
	copy of the rawrite.exe utility and its documentation.  This
	program is needed to correctly copy the bootable filesystem
	image to the floppy, since it's an image of a unix partition
	containing a ffs filesystem, not a MSDOS format diskette.

	Once you have installed rawrite.exe, just run it and specify the
	name of the bootable image, such as "floppy{:--:}OSrev.fs" and the name of
	the floppy drive, such as "a:".  Be sure to use good quality HD
	(1.44MB) floppies, formatted on the system you're using.  The
	image copy and boot process is not especially tolerant of read
	errors. 

	Note that if you are using NT to write the images to disk, you
	will need to use ntrw.exe instead.  It is also available in the
	"tools" directory.  Grab it and run in with the correct 
	arguments like this "ntrw <image> <drive>:"

	Note that, when installing, the boot floppy can be write-protected
	(i.e  read-only).-:})dnl
dnl
define({:-OpenBSDXferFloppyFromUNIX-:},
{:-Creating a bootable floppy disk using SunOS or other Un*x-like system:

	First, you will need obtain a local copy of the bootable filesystem
	image as described above.  If possible use the cksum(1) or md5(1) 
	commands to verify the checksums of the images vs. the values in 
	the CKSUM or MD5 files on the mirror site.

	Next, use the dd(1) utility to copy the file to the floppy drive.
	Under SunOS, the command would be:

		dd if=floppy{:--:}OSrev.fs of=/dev/rfd0c bs=36b

	If you are using something other than SunOS, you may have to adapt
	this to conform to local naming conventions for the floppy and
	options suitable for copying to a "raw" floppy image.  The key
	issue is that the device name used for the floppy *must* be one
	that refers to the correct block device, not a partition or
	compatibility mode, and the copy command needs to be compatible
	with the requirement that writes to a raw device must be in
	multiples of 512-byte blocks.  The variations are endless and

{:-Create an installation tape:

	While you won't be able to boot OpenBSD from a tape, you can use
	one to provide the installation sets.  To do so, you need to make
	a tape that contains the distribution set files, each in "tar"
	format or in "gzipped tar format".  First you will need to
	transfer the distribution sets to your local system, using ftp or
	by mounting the CD-ROM containing the release.  Then you need to
	make a tape containing the files. 
        
	If you're making the tape on a UN*X-like system, the easiest way
	to do so is make a shell script along the following lines, call it
	"/tmp/maketape". 
        
	#! /bin/sh
	tape=/dev/nrst0
	mt -f ${tape} rewind

	tar cf ${tape} bsd
	mt -f ${tape} offline
	# end of script

	And then:

	cd .../OSREV/MACHINE
	sh -x /tmp/maketape

	If you're using a system other than OpenBSD or SunOS, the tape

{:-To install OpenBSD using a remote partition, mounted via
NFS, you must do the following:

	NOTE:	This method of installation is recommended only for
		those already familiar with using BSD network
		configuration and management commands.  If you aren't,
		this documentation should help, but is not intended to
		be all-encompassing.

	Place the OpenBSD distribution sets you wish to install
	into a directory on an NFS server, and make that directory
	mountable by the machine on which you are installing or
	upgrading OpenBSD.  This will probably require modifying
	the /etc/exports file of the NFS server and resetting
	its mount daemon (mountd).  (Both of these actions will
	probably require superuser privileges on the server.)

	You need to know the numeric IP address of the NFS
	server, and, if the server is not on a network directly
	connected to the machine on which you're installing or
	upgrading OpenBSD, you need to know the numeric IP address
	of the router closest to the OpenBSD machine.  Finally,
	you need to know the numeric IP address of the OpenBSD
	machine itself.

	Once the NFS server is set up properly and you have the
	information mentioned above, you can proceed to the next
	step in the installation or upgrade process.  If you're
	installing OpenBSD from scratch, go to the section on
	preparing your hard disk, below.  If you're upgrading an
	existing installation, go directly to the section on
	upgrading.-:})dnl

	in your current file system tree.  At a bare minimum, you
	must upgrade the "base" binary distribution, and so must
	put the "base{:--:}OSrev" set somewhere in your file system.  It
