<title>Installing &os;</title>

<para>This text describes how to install and boot the &arch; port.
|
|
Users of this port are encouraged to subscribe to the
|
|
&a.sparc;.</para>
|
|
|
|
<warning>
|
|
<para>The kernel and userland binaries mentioned below are highly
|
|
experimental (for example, the kernel contains some ATA changes
|
|
and EEPROM handling code which could potentially be dangerous).
|
|
Unless you know what you are doing and are willing to cope with
|
|
any damage that might arise, you should probably not be trying
|
|
this.</para>
|
|
</warning>
|
|
|
|
<para>Unlike &os;/i386 or &os;/alpha, there is no version of
|
|
&man.sysinstall.8; for &os;/&arch;. The installation procedure
|
|
consists of loading a kernel (either from CDROM or the network)
|
|
onto the &arch; machine, with a root filesystem on CDROM or
|
|
exported via NFS. The utilities on the root filesystem can then
|
|
be used to partition the local disk on the &arch; machine and
|
|
optionally to copy the &os; distribution to the local disk to make
|
|
a stand-alone machine.</para>
|
|
|
|
<para>Currently, there are two ways to install &os;/&arch; on a new
|
|
machine. By far the easier of the two is to install from CDROM;
|
|
this method allows you to install &os; without any dependencies on
|
|
any other computers.</para>
|
|
|
|
<para>If installing from CDROM is impossible or undesirable, the
|
|
alternative is to install over the network. This requires another
|
|
machine, suitably configured, to serve the boot loader, kernel,
|
|
and root filesystem to the new machine, via a combination of
|
|
RARP, TFTP, and either BOOTP or DHCP. This netboot server can be
|
|
another &os; machine, but is not required to be.</para>
|
|
|
|
<para>You will need to decide which of these methods you want to use
|
|
for installation, as this will determine the set of files you need
|
|
to download (if any), as well as the steps required to do the
|
|
installation.</para>

<para>Most &arch; systems are set up to boot automatically from

<para>To do this, reboot the system, and wait until the boot

<para>For a network installation, you will need several files.

First, you will need to download a &os;/&arch; loader for

&man.tftpd.8; to serve to your &arch; client. The loader will
|
|
use either TFTP or NFS to retrieve the &os; kernel from the

netboot server. There is a separate loader for each of these
|
|
methods (i.e. a loader for TFTP and a loader for NFS). You

should download one of the following files, as

|
appropriate:</para>

<para>If you have trouble booting, it is very helpful to use

&man.tcpdump.1; to monitor the TFTP requests. This will allow

<title>Setting up bootpd/dhcpd</title>
|

<para>You can use either BOOTP or DHCP (both not both) to

provide some parameters to the boot loader, such as a

machine's IP address. If you are using another &os; machine

as a netboot server, the BOOTP functionality is provided by

&man.bootpd.8;, which is a part of the &os; base system.

Several DHCP servers are provided in the &os; Ports
|
|
Collection.</para>

<para>If you are going to use &man.bootpd.8;, create entries for

your &os;/&arch; system in the server's

more details):</para>

<para>The Ethernet address must be the same as the one in the

TFTP example above, but it is specified hexadecimal notation

without colons (for the example above, this would be

|
<literal>0003ba0b92d4</literal>). NFS/TFTP specific entries
|
|
can be omitted if the given method is not used. The strings
|
|
given in the <literal>hd</literal> and <literal>bf</literal>
|
|
properties are concatenated to give the boot file name. If
|
|
your kernel is named differently or you use another directory,
|
|
change these values as required. If you are booting using
|
|
NFS, remove the <literal>bf</literal> and
|
|
<literal>hd</literal> settings (or change them to specify the

|
directory and file inside the NFS root hierarchy in which the

kernel will reside). The name of the host entry is

conventionally the host name without the domain

appended.</para>

<para>For a DHCP server, add an entry similar to the following

entry for <application>ISC DHCP</application> version 2

(available in the &os; Ports Collection as <filename

|
<para>The <literal>filename</literal> option corresponds to the
|
|
concatenation of <literal>hd</literal> and

<literal>bf</literal> in <filename>/etc/bootptab</filename>.
|
|
The Ethernet address is specified in hexadecimal with colons,

just like in the &man.rarpd.8; example above.
|
|
<literal>options root-path</literal> corresponds to
|

<literal>rp</literal> in <filename>/etc/bootptab</filename>.
|

If the name given in <literal>option host-name</literal> is

resolvable, i.e. has a DNS entry or is associated with an

omitted.</para>

TFTP and NFS. (You specified one of these two alternatives by

picking a loader.)</para>
|

the kernel to the directory you specified using

<title>Loading the Base System to the Netboot Server</title>

|
<para>You must extract the base system distribution image to the

NFS root directory specified either by the
|
|
<literal>rp</literal> option in
|
|
<filename>/etc/bootptab</filename> or the
|
|
<literal>root-path</literal> option in
|

<filename>dhcpd.conf</filename>. This directory tree will
|
|
become the &arch;'s root filesystem once the kernel is booted.
|
|
Besides providing a normal userland environment, it also
|
|
contains all of the necessary utilities for you to install the
|
|
distribution on the &arch; client's local disk.</para>
|
|
|
|
<para>Using whatever editing tools you have on the netboot
|
|
server, you probably will want to edit the &arch;'s
|

<filename>/etc/fstab</filename> and

<filename>/etc/rc.conf</filename> and set a

<username>root</username> password.</para>

<para>If all goes well, you can now boot the &os; on your &arch;
|
|
machine by dropping into the PROM prompt as described in <xref
|
|
linkend="getting-to-prom-prompt">. Now, just type
|
|
<command>boot net</command> and the system should boot.
|
|
Specifically, the loader is retrieved via TFTP, it then does a
|
|
BOOTP request and will proceed to load the kernel (either
|
|
using TFTP or NFS, depending on your choice of loader). Then,
|
|
it should wait 10 seconds for user input and proceed to
|
|
execute the kernel.</para>
|
|
|
|
<para>If something does not work in between, and you suspect
|
|
TFTP/NFS/BOOTP problems, <application>Ethereal</application>
|
|
(available in the &os; Ports Collection as <filename
|
|
role="package"> net/ethereal</filename>) is usually helpful.
|
|
The most common problems are related to bad file permissions.
|

some circumstances, refer to the manual page for

<para>If you want to boot from a local disk, you will need to
|
|
create a root filesystem to hold the base system binaries and
|
|
configuration files (and optionally other filesystems mounted
|
|
in places such as <filename>/usr</filename> and
|
|
<filename>/var</filename>).</para>
|
|
|
|
<para>The kernel contains support for Sun disklabels, so you can
|
|
use Solaris disks, which may even be prepared using
|
|
<application>newfs</application> under Solaris. NetBSD disk
|
|
labels and filesystems are also usable from &os;.</para>

<warning>
|

<para>Do <emphasis>not</emphasis> run Solaris
|
|
<application>fsck</application> on filesystems modified by

&os;. Doing so will damage the file permissions.</para>

<para>To create filesystems and to install the base system, boot

<para>When booting the first time and you have not entered your
|
|
root partition into <filename>/etc/fstab</filename> yet, you may
|
|
need to specify your root partition on the mountroot prompt when
|
|
booting (use a format like
|
|
<command>ufs:<replaceable>disk</replaceable><replaceable>partition</replaceable></command>,
|
|
i.e. leave the slice specification out). If the kernel does
|
|
automatically attempt to boot from another filesystem, press a
|
|
key other than <keycap>Enter</keycap> on the
|
|
<application>loader</application> prompt:</para>
|
|
|
|
<screen>Hit [Enter] to boot immediately, or any other key for command prompt.</screen>
|
|
|
|
<para>Then, boot the kernel using <command>boot -a -s</command>,
|
|
which will cause the kernel to ask you for the root partition
|
|
and then boot into single-user mode. Once the root filesystem
|
|
has been entered into <filename>/etc/fstab</filename>, it should
|
|
be automatically mounted as <filename>/</filename> on the next

boot.</para>

BOOTP entries should suffice to have the kernel find and mount

the root filesystem via NFS.</para>
