This file has architecture-dependent installation instructions, culled
from {alpha,i386}/INSTALL.TXT.
-->
<sect1 id="install">
<title>Installing &os;</title>
<para>This section documents the process of installing a new
distribution of &os;. These instructions pay particular emphasis to
the process of obtaining the &os; &release.current; distribution and
to beginning the installation procedure. The <ulink
url="&url.books.handbook;/install.html"><quote>Installing
&os;</quote></ulink>
chapter of the <ulink
url="&url.books.handbook;/">&os;
Handbook</ulink> provides more in-depth information about the
installation program itself, including a guided walkthrough with
screenshots.</para>
<para>If you are upgrading from a previous release
of &os;, please see <xref linkend="upgrading"> for instructions on
upgrading.</para>
<sect2 id="getting-started">
<title>Getting Started</title>
<para>Probably the most important pre-installation step that can
be taken is that of reading the various instruction documents
provided with &os;. A roadmap of documents pertaining to this
release of &os; can be found in <filename>README.TXT</filename>,
which can usually be found in the same location as this file; most
of these documents, such as the release notes and the hardware
compatibility list, are also accessible in the Documentation menu
of the installer.</para>
<para>Note that on-line versions of the &os; <ulink
url="&url.books.faq;/">FAQ</ulink> and <ulink
url="&url.books.handbook;/">Handbook</ulink> are also
available from the <ulink url="&url.base;/">&os;
Project Web site</ulink>, if you have an Internet
connection.</para>
<para>This collection of documents may seem daunting, but the time
spent reading them will likely be saved many times over. Being
familiar with what resources are available can also be helpful in
the event of problems during installation.</para>
<para>The best laid plans sometimes go awry, so if you run into
trouble take a look at <xref linkend="trouble">, which contains
valuable troubleshooting information. You should also read
an updated copy of
<filename>ERRATA.TXT</filename> before installing,
since this will alert you to
any problems which have reported in the interim for your
particular release.</para>
<important>
<para>While &os; does its best to safeguard against
accidental loss of data, it's still more than possible to
<emphasis>wipe out your entire disk</emphasis>
with this installation if you make a
mistake. Please do not proceed to the final &os;
installation menu unless you've adequately backed up any
important data first.</para>

<title>Hardware Requirements</title>
<!-- i386/pc98 text starts here -->
<para arch="i386,pc98">&os; for the &arch.print; requires a 486 or better
processor and at least 24 MB of RAM.
You will need at least 150MB of free hard drive space for the
most minimal installation. See below for ways of shrinking
existing DOS partitions in order to install &os;.</para>
<!-- alpha text starts here -->
<para arch="alpha">&os; for the &arch.print; supports the platforms
described in <filename>HARDWARE.TXT</filename>.</para>
<para arch="alpha">You will need a dedicated disk for
&os;/alpha. It is not possible to share a disk with another
operating system at this time. This disk will need to be attached
to a SCSI controller which is supported by the SRM firmware or an
IDE disk assuming the SRM in your machine supports booting from
IDE disks.</para>
<para arch="alpha">Your root filesystem MUST be the first
partition (partition <literal>a</literal>) on the disk to be
bootable.</para>
<para arch="alpha">You will need the SRM console firmware for your
platform. In some cases, it is possible to switch between
AlphaBIOS (or ARC) firmware and SRM. In others it will be
necessary to download new firmware from the vendor's Web
site.</para>
<!-- sparc64 text starts here -->
<para arch="sparc64">&os; for the &arch.print; supports the platforms
described in <filename>HARDWARE.TXT</filename>.</para>
<para arch="sparc64">You will need a dedicated disk for
&os;/sparc64. It is not possible to share a disk with another
operating system at this time.</para>
<!-- amd64 text starts here -->
<para arch="amd64">&os; for the &arch.print; requires an
Athlon64, Athlon64-FX, Opteron or better processor to run.</para>
<para arch="amd64">If you have an machine based on an
nVidia nForce3 Pro-150, you MUST use the BIOS setup to
disable the IO APIC. If you do not have an option
to do this, you will likely have to disable ACPI
instead. There are bugs in the Pro-150 chipset that
we have not found a workaround for yet.</para>
<!-- generic text starts here -->
<para>If you are
not familiar with configuring hardware for &os;, you should
be sure to read the <filename>HARDWARE.TXT</filename> file;
it contains important
information on what hardware is supported by &os;.</para>
</sect2>
<sect2 id="floppies">
<title>Floppy Disk Image Instructions</title>
<para arch="i386,alpha,pc98">Depending on how you choose to install &os;, you may need to
create a set of floppy disks (usually three) to begin the installation
process. This section briefly describes how to create these disks,
either from a CDROM installation or from the Internet. Note that in
the common case of installing &os; from CDROM, on a machine that
supports bootable CDROMs, the steps outlined in this section will
not be needed and can be skipped.</para>
<para arch="i386,alpha">For most CDROM or network installations, all you need to
copy onto actual floppies from the <filename>floppies/</filename> directory are the
<filename>boot.flp</filename> and <filename>kern<replaceable>X</replaceable>.flp</filename>
images (for 1.44MB floppies).</para>
<para arch="pc98">For a normal CDROM or network installation, all you need
to copy onto actual floppies from the <filename>floppies/</filename>
directory are the <filename>boot.flp</filename> and <filename>kern<replaceable>X</replaceable>.flp</filename>
images (for 1.44MB floppies) or <filename>boot-small.flp</filename> and
<filename>kern-small.flp</filename> images (for 1.2MB floppies).</para>

drive on your system and wish to use a &os; distribution CD
in the CDROM drive of another system to which you have network

<itemizedlist>
<listitem>
<para>If you would be able to FTP install &os; directly
from the CDROM drive in some &os; machine, it's quite
easy: You ensure an FTP server is running and then
simply add the following line to the password file
(using the &man.vipw.8; command):</para>
<screen>ftp:*:99:99::0:0:FTP:/cdrom:/sbin/nologin</screen>
<para>On the machine on which you are running the install,
go to the Options menu and set Release Name to
<literal>any</literal>. You may then choose a Media type of
<literal>FTP</literal> and type in
<filename>ftp://<replaceable>machine</replaceable></filename>
after picking <quote>URL</quote> in the ftp sites
menu.</para>
<warning>
<para>This may allow anyone on the local network (or Internet) to
make <quote>anonymous FTP</quote> connections to this
machine, which may not be desirable.</para>
</warning>
</listitem>
<listitem>
<para>If you would rather use NFS to export the CDROM
directly to the machine(s) you'll be installing from, you
need to first add an entry to the
<filename>/etc/exports</filename> file (on the machine with
the CDROM drive). The example below allows the machine
<hostid role="hostname">ziggy.foo.com</hostid> to mount the
CDROM directly via NFS during installation:</para>
<screen>/cdrom -ro ziggy.foo.com</screen>
<para>The machine
with the CDROM must also be configured as an NFS server, of
course, and if you're not sure how to do that then an NFS
installation is probably not the best choice for you unless
you're willing to read up on &man.rc.conf.5; and configure things
appropriately. Assuming that this part goes smoothly, you
should be able to enter: <filename><replaceable>cdrom-host</replaceable>:/cdrom</filename> as the path for
an NFS installation when the target machine is installed,
e.g. <filename>wiggy:/cdrom</filename>.</para>

<title>Installing from Floppies</title>
<para>If you must install from floppy disks, either due to
unsupported hardware or just because you enjoy doing things the
hard way, you must first prepare some floppies for the
install.</para>
<para>First, make your boot floppies as described in
<xref linkend="floppies">.</para>
<para>Second, peruse <xref linkend="layout"> and pay special attention
to the <quote>Distribution Format</quote> section since it describes which
files you're going to need to put onto floppy and which you can
safely skip.</para>
<para>Next you will need, at minimum, as many 1.44MB floppies as
it takes to hold all files in the <filename>bin</filename>
(binary distribution) directory. If you're preparing these
floppies under DOS, then these floppies
<emphasis>must</emphasis> be formatted using the MS-DOS
<filename>FORMAT</filename> command. If you're using Windows,
use the Windows File Manager format command.</para>
<important>
<para>Frequently, floppy disks come <quote>factory
preformatted</quote>. While convenient,
many problems reported by users in the past have resulted
from the use of improperly formatted media.
Re-format them yourself, just to make sure.</para>
</important>
<para>If you're creating the floppies from another &os;
machine, a format is still not a bad idea though you don't need
to put a DOS filesystem on each floppy. You can use the
&man.disklabel.8; and &man.newfs.8; commands to put a UFS filesystem on a
floppy, as the following sequence of commands
illustrates:</para>
<screen>&prompt.root; <userinput>fdformat -f 1440 fd0</userinput>
&prompt.root; <userinput>disklabel -w fd0 floppy3</userinput>
&prompt.root; <userinput>newfs -i 65536 /dev/fd0</userinput></screen>
<para>After you've formatted the floppies for DOS or UFS, you'll
need to copy the files onto them.
The distribution files are sized so that a floppy disk will hold
a single file.
Each distribution should go into its own subdirectory on the floppy,
e.g.: <filename>a:\bin\bin.inf</filename>, <filename>a:\bin\bin.aa</filename>, <filename>a:\bin\bin.ab</filename>, ...</para>
<important>
<para>The <filename>bin.inf</filename> file also needs to go on the first floppy of
the <filename>bin</filename> set since it is read by the installation program in
order to figure out how many additional pieces to look for
when fetching and concatenating the distribution. When
putting distributions onto floppies, the
<filename>distname.inf</filename> file <emphasis>must</emphasis> occupy the first
floppy of each distribution set.</para>
</important>
<para>Once you come to the Media screen of the install, select
<quote>Floppy</quote> and you'll be prompted for the rest.</para>

<title>Installing from QIC/SCSI Tape</title>
<para>When installing from tape, the installation program
expects the files to be simply tar'ed onto it, so after fetching
all of the files for the distributions you're interested in,
simply use &man.tar.1; to get them onto the tape with a command something like
this:</para>
<screen>&prompt.root; <userinput>cd <replaceable>/where/you/have/your/dists</replaceable></userinput>
&prompt.root; <userinput>tar cvf /dev/sa0 <replaceable>dist1</replaceable> .. <replaceable>dist2</replaceable></userinput></screen>
<para>When you go to do the installation, you should also make
sure that you leave enough room in some temporary directory
(which you'll be allowed to choose) to accommodate the <emphasis>full</emphasis>
contents of the tape you've created. Due to the non-random
access nature of tapes, this method of installation requires
quite a bit of temporary storage. You should expect to require
as much temporary storage as you have stuff written on tape.</para>
<note>
<para>When going to do the installation, the tape must be in
the drive <emphasis>before</emphasis> booting from the boot floppies. The
installation <quote>probe</quote> may otherwise fail to find it.</para>
</note>
<para>Now create a boot floppy as described in <xref linkend="floppies"> and
proceed with the installation.</para>
</sect3>
<sect3 id="ftpnfs">
<title>Installing over a Network using FTP or NFS</title>
<para>After making the boot floppies as described in the first
section, you can load the rest of the installation over a
network using one of 3 types of connections: serial port,
parallel port, or Ethernet.</para>
<sect4>
<title>Serial Port</title>
<para>SLIP support is rather primitive, and is limited
primarily to hard-wired links, such as a serial cable running
between two computers. The link must be hard-wired because
the SLIP installation doesn't currently offer a dialing
capability. If you need to dial out with a modem or otherwise
dialog with the link before connecting to it, then the PPP
utility should be used instead.</para>
<para>If you're using PPP, make sure that you have your
Internet Service Provider's IP address and DNS information
handy as you'll need to know it fairly early in the
installation process. You may also need to know your own IP
address, though PPP supports dynamic address negotiation and
may be able to pick up this information directly from your ISP
if they support it.</para>
<para>You will also need to know how to use the various <quote>AT
commands</quote> for dialing out with your particular brand of modem
as the PPP dialer provides only a very simple terminal
emulator.</para>
</sect4>
<sect4>
<title>Parallel Port</title>
<para>If a hard-wired connection to another &os; or Linux
machine is available, you might also consider installing over
a <quote>laplink</quote> style parallel port cable. The data rate over the
parallel port is much higher than what is typically possible
over a serial line (up to 50k/sec), thus resulting in a
quicker installation. It's not typically necessary to use
<quote>real</quote> IP addresses when using a point-to-point parallel cable
in this way and you can generally just use RFC 1918 style
addresses for the ends of the link (e.g. <hostid
role="ipaddr">10.0.0.1</hostid>, <hostid role="ipaddr">10.0.0.2</hostid>,
etc).</para>
<important>
<para>If you use a Linux machine rather than a &os;
machine as your PLIP peer, you will also have to specify
<option>link0</option> in the TCP/IP setup screen's <quote>extra options for
ifconfig</quote> field in order to be compatible with Linux's
slightly different PLIP protocol.</para>
</important>
</sect4>
<sect4>
<title>Ethernet</title>
<para>&os; supports most common Ethernet cards; a table
of supported cards is
provided as part of the &os; Hardware Notes (see
<filename>HARDWARE.TXT</filename> in
the Documentation menu on the boot floppy or the top level
directory of the CDROM). If you are using one of the
supported PCMCIA Ethernet cards, also be sure that it's
plugged in <emphasis>before</emphasis> the laptop is powered on. &os; does
not, unfortunately, currently support <quote>hot insertion</quote> of
PCMCIA cards during installation.</para>
<para>You will also need to know your IP address on the
network, the <option>netmask</option> value for your subnet and the
name of your machine. Your system administrator can tell you
which values are appropriate to your particular network setup.
If you will be referring to other hosts by name rather than IP
address, you'll also need a name server and possibly the
address of a gateway (if you're using PPP, it's your
provider's IP address) to use in talking to it. If you want
to install by FTP via an HTTP proxy (see below), you will also
need the proxy's address.</para>
<para>If you do not know the answers to these questions then
you should really probably talk to your system administrator
<emphasis>first</emphasis> before trying this type of
installation. Using a randomly chosen IP address or netmask
on a live network is almost guaranteed not to work, and will
probably result in a lecture from said system administrator.</para>
<para>Once you have a network connection of some sort working, the
installation can continue over NFS or FTP.</para>
</sect4>
<sect4>
<title>NFS installation tips</title>
<para>NFS installation is fairly straight-forward: Simply copy
the &os; distribution files you want onto a server
somewhere and then point the NFS media selection at it.</para>
<para>If this server supports only <quote>privileged port</quote> access (this is
generally the default for Sun and Linux workstations), you
may need to set this option in the Options menu before
installation can proceed.</para>
<para>If you have a poor quality Ethernet card which suffers from very
slow transfer rates, you may also wish to toggle the appropriate
Options flag.</para>
<para>In order for NFS installation to work, the server must
also support <quote>subdir mounts</quote>, e.g. if your &os;
distribution directory lives on
<filename>wiggy:/usr/archive/stuff/FreeBSD</filename>, then
<hostid role="hostname">wiggy</hostid> will have to allow
the direct mounting of <filename>/usr/archive/stuff/FreeBSD</filename>, not just
<filename>/usr</filename> or <filename>/usr/archive/stuff</filename>.</para>
<para>In &os;'s <filename>/etc/exports</filename> file this is controlled by the
<option>-alldirs</option> option. Other NFS servers may have different
conventions. If you are getting <literal>Permission Denied</literal> messages
from the server then it's likely that you don't have this
properly enabled.</para>
</sect4>
<sect4>
<title>FTP Installation tips</title>
<para>FTP installation may be done from any mirror site containing a
reasonably up-to-date version of &os;. A full menu of
reasonable choices for almost any location in the world is
provided in the FTP site menu during installation.</para>
<para>If you are installing from some other FTP site not listed in
this menu, or you are having troubles getting your name server
configured properly, you can also specify your own URL by
selecting the <quote>URL</quote> choice in that menu. A URL can
contain a hostname or an IP address, so something like the following would
work in the absence of a name server:</para>
<screen>ftp://216.66.64.162/pub/FreeBSD/releases/&arch;/4.2-RELEASE</screen>
<para>There are three FTP installation modes you can use:</para>
<itemizedlist>
<listitem>
<para>FTP: This method uses the standard
<quote>Active</quote> mode for transfers, in which the
server initiates a connection to the client. This will
not work through most firewalls but will often work best
with older FTP servers that do not support passive mode.
If your connection hangs with passive mode, try this
one.</para>
</listitem>
<listitem>
<para>FTP Passive: This sets the FTP "Passive" mode

the client. This option is best for users to pass
through firewalls that do not allow incoming connections
on random port addresses.</para>

<listitem>
<para>FTP via an HTTP proxy: This option instructs &os;
to use HTTP to connect to a proxy for all FTP
operations. The proxy will translate the requests and
send them to the FTP server. This allows the user to
pass through firewalls that do not allow FTP at all, but
offer an HTTP proxy. You must specify the hostname of
the proxy in addition to the FTP server.</para>
<para>In the rare case that you have an FTP proxy that
does not go through HTTP, you can specify the URL as
something like:</para>
<screen><userinput>ftp://foo.bar.com:<replaceable>port</replaceable>/pub/FreeBSD</userinput></screen>
<para>In the URL above, <replaceable>port</replaceable>
is the port number of the proxy FTP server.</para>

<title>Tips for Serial Console Users</title>
<para>If you'd like to install &os; on a machine using just a
serial port (e.g. you don't have or wish to use a VGA card),
please follow these steps:</para>
<procedure>
<step>
<para>Connect some sort of ANSI (vt100) compatible terminal
or terminal emulation program to the <devicename>COM1</devicename> port of the PC you
are installing &os; onto.</para>
</step>
<step>
<para>Unplug the keyboard (yes, that's correct!) and then
try to boot from floppy or the installation CDROM, depending
on the type of installation media you have, with the
keyboard unplugged.</para>
</step>
<step>
<para>If you don't get any output on your serial console,
plug the keyboard in again. If you are booting from the
CDROM, proceed to <xref linkend="hitspace"> as soon as you
hear the beep.</para>
</step>
<step>
<para>If booting from floppies, when access to the disk stops, insert
the first of the <filename>kern<replaceable>X</replaceable>.flp</filename> disks and press
<keycap>Enter</keycap>. When access to this disk finishes, insert
the next <filename>kern<replaceable>X</replaceable>.flp</filename> disk and press <keycap>Enter</keycap>,
and repeat until all <filename>kern<replaceable>X</replaceable>.flp</filename> disks have been
inserted. When disk activity finishes, reinsert the <filename>boot.flp</filename>
floppy disk and press <keycap>Enter</keycap>.</para>

<step id="hitspace">
<para>Once a beep is heard, hit the number <keycap>6</keycap>, then enter</para>
<screen><userinput>boot -h</userinput></screen>
<para>and you should now definitely be seeing everything on
the serial port. If that still doesn't work, check your
serial cabling as well as the settings on your terminal
emulation program or actual terminal device. It should be
set for 9600 baud, 8 bits, no parity.</para>

<qandaset arch="i386,amd64">
<qandaentry>
<question>
<para>Help! I have no space! Do I need to delete
everything first?</para>
</question>
<answer>
<para>If your machine is already running DOS and has little
or no free space available for &os;'s installation, all is
not lost! You may find the <application>FIPS</application>
utility, provided in the <filename>tools/</filename>
subdirectory on the &os; CDROM or on the various &os; ftp
sites, to be quite useful.</para>
<para><application>FIPS</application> allows you to split an
existing DOS partition into two pieces, preserving the
original partition and allowing you to install onto the
second free piece. You first <quote>defrag</quote> your DOS
partition, using the DOS 6.xx <filename>DEFRAG</filename>
utility or the <application>Norton Disk Tools</application>,
then run FIPS. It will
prompt you for the rest of the information it needs.
Afterwards, you can reboot and install &os; on the new
partition. Also note that FIPS will create the second
partition as a <quote>clone</quote> of the first, so you'll
actually see that you now have two DOS Primary partitions
where you formerly had one. Don't be alarmed! You can
simply delete the extra DOS Primary partition (making sure
it's the right one by examining its size).</para>
<para><application>FIPS</application> does NOT currently
work with NTFS style partitions. To split up such a
partition, you will need a commercial product such as
<application>Partition Magic</application>. Sorry, but this
is just the breaks if you've got a Windows partition hogging
your whole disk and you don't want to reinstall from
scratch.</para>
<para><application>FIPS</application> does not work on
extended DOS partitions. Windows 95/98/ME FAT32 primary
partitions are supported.</para>
</answer>
</qandaentry>
<qandaentry>
<question>
<para>Can I use compressed DOS filesystems from
&os;?</para>
</question>
<answer>
<para>No. If you are using a utility such as
<application>Stacker</application>(tm) or
<application>DoubleSpace</application>(tm), &os; will only
be able to use whatever portion of the filesystem you leave
uncompressed. The rest of the filesystem will show up as
one large file (the stacked/dblspaced file!). <emphasis>Do
not remove that file</emphasis> as you will probably regret
it greatly!</para>
<para>It is probably better to create another uncompressed DOS
extended partition and use this for communications between
DOS and &os; if such is your desire.</para>
</answer>
</qandaentry>
<qandaentry>
<question>
<para>Can I mount my DOS extended partitions?</para>
</question>
<answer>
<para>Yes. DOS extended partitions are mapped in at the end
of the other <quote>slices</quote> in &os;, e.g. your <devicename>D:</devicename> drive might
be <filename>/dev/da0s5</filename>, your <devicename>E:</devicename> drive <filename>/dev/da0s6</filename>, and so on. This
example assumes, of course, that your extended partition is
on SCSI drive 0. For IDE drives, substitute <literal>ad</literal> for
<literal>da</literal> appropriately. You otherwise mount extended
partitions exactly like you would mount any other DOS drive,
e.g.:</para>
<screen>&prompt.root; <userinput>mount -t msdos /dev/da0s5 /dos_d</userinput></screen>

<question>
<para>Can I run DOS binaries under &os;?</para>
</question>
<answer>
<para>Ongoing work with BSDI's &man.doscmd.1; utility will
suffice in many cases, though
it still has some rough edges. The
<filename role="package">emulators/doscmd</filename> port/package
can be found in the &os; Ports Collection.
If you're interested in
working on this, please send mail to the &a.emulation;
and indicate that you're interested in joining this ongoing
effort!</para>
<para>The <filename role="package">emulators/pcemu</filename> port/package in the
&os; Ports Collection which emulates an 8088 and enough BIOS
services to run DOS text mode applications. It requires the
X Window System (XFree86) to operate.</para>
</answer>
</qandaentry>
<qandaentry>
<question>
<para>Can I run µsoft.windows; applications under &os;?</para>
</question>
<answer>
<para>There are several ports/packages in the &os; Ports Collection
which can enable the use of many &windows; applications.
The <filename role="package">emulators/wine</filename> port/package
provides a compatibility layer on top of &os; which allow many
&windows; applications to be run within X Windows (XFree86).
</answer>
</qandaentry>
<qandaentry>
<question>
<para>Can I run other Operating Systems under &os;?</para>
</question>
<answer>
<para>Again, there are several ports/packages in the &os; Ports Collection
which simulate "virtual machines" and allow other operating systems to run
on top of &os;.
The <filename role="package">emulators/bochs</filename> port/package
allows µsoft.windows;, Linux and even other copies of &os; to be run within a
window on the &os; desktop.
The <filename role="package">emulators/vmware2</filename> and
<filename role="package">emulators/vmware3</filename> ports/packages
allow the commercial VMware virtual machine software to be run on &os;.</para>
