<para>This document outlines the procedures to get the &PA;/&L;
kernel to boot on your &PA; system. It also explains the usage of &PO;,
the kernel loader for &PL;. You will find much information on how to
compile a kernel from the source available at
<ulink url="http://cvs.parisc-linux.org/">http://cvs.parisc-linux.org/</ulink>.
Please note that this HOWTO version is newer than Deb Richardson&apos;s and
includes more accurate information because of the progress of the port.
Nevertheless, it&apos;s worth mentioning that this document kept parts of Deb&apos;s
original work and unveiled some remarkable information.</para>

<title>Introduction</title>
<para>You just received this &PA; box you bought online, or maybe you
got it from your company scrapyard. Anyway, here comes the question of the
operating system you are going to use. The &PL; project consists in porting
&L; to the &PA; architecture, and we hope that if you decide to use it on
your box, this HOWTO will help you in the process of setting it up.</para>
<para>In addition to porting the &L; kernel, the development team is working
on porting the &D; project to &PA;. In fact, by the time we wrote this
document, over 97% of the package pool is available for the stable
&D; release (3.1, aka <emphasis>Sarge</emphasis>) on hppa (see
<ulink url="http://buildd.debian.org/stats/hppa.txt">the buildd stats</ulink>
for detailed data). Some &D; developers and users reported that the
port was one of the easiest to install, as it feels like installing an
i386 system.</para>
<para>For more information about the &PA;/&L; porting project,
please see <ulink url="http://www.parisc-linux.org/">http://www.parisc-linux.org/</ulink>, or a mirror site like
<ulink url="http://www.fr.parisc-linux.org/">http://www.fr.parisc-linux.org/</ulink>.
This site deals with kernel development and improvement. For user-space
troubles, please refer to
<ulink url="http://www.debian.org/ports/hppa/">&D; hppa port pages</ulink>.</para>
<para>In a few words, this HOWTO is aimed at anyone looking for some
help and information about using &L; on a &PA; system. No particular prior
knowledge is necessary but bases about how &D; packages work, and general
background about &L; can be helpful.</para>
<para>It is also worth mentioning that some sections of the present document
aren&apos;t Linux-centric, and may be of use to people dealing with other OSes,
such as BSDs or even HP-UX.</para>
<para>After listing supported hardware, this HOWTO explains some commands
of the Boot Console Handler (<acronym>BCH</acronym>) available at boot time. Then, the
features of the &PL; kernel loader are introduced in another chapter,
and finally many ways to get your system up and running are detailed.
At the end, the text goes deep in the kernel compilation and configuration,
as well as a few appendices giving some extra hints.</para>
</preface>
<chapter id="hardware">
<title>Supported Hardware</title>
<para>With the release of &PA; architecture in &D;&nbsp;3.0
(aka <emphasis>Woody</emphasis>), a major improvement was
made in term of quantity and quality of hardware support.
Since 0.9.3 released<footnote id="ftn-debian-support"><para>
Before the first release of Debian on hppa,
there has been unofficial releases of Woody snapshots, entitled "&PL; releases",
and numbered <emphasis>0.x</emphasis>. Immediately after the release of Woody,
the &PL; port switched to the normal Debian numbering scheme. In other words,
&D; 3.0 is consecutive to &PL; 0.9.3.</para></footnote>, the kernel has been
greatly improved, so that much unsupported hardware by the time 0.9.3 went out
is now handled. That&apos;s why even if your model is not listed here, you might
give it a try and report your result to the mailing list:
<email>parisc-linux@lists.parisc-linux.org</email>.
</para>
<note><para>Mind that as of this document&apos;s publication date, the 2.4 series of the
Linux kernel are deemed obsolete, and no development happens in that branch.
Any new comer to the PA-RISC/Linux port should look at the 2.6 kernel series,
which supports much more hardware than the 2.4 does. Accordingly, one will not try
to use the now aging <emphasis>Woody</emphasis> release and will instead focus
on its successor: <emphasis>Sarge</emphasis>, or even better, the upcoming
<emphasis>Etch</emphasis>.</para></note>
<para>The following &PA; machines should work just fine, provided that you follow the
instructions of the present document.
Please note that this list can change at any time.
The best way to get an up to date version is to look at
<ulink url="http://www.pateam.org/list.html">http://www.pateam.org/list.html</ulink>.
This is the place to find relevant information about a specific model,
including special boot procedures.

<title>Preparing to boot</title>
<highlights><para>Like any other system, machines based on &PA; processors have to
go through several steps in order to get &L; up and running. The next
section introduces you to the early boot management of your &PA; computer.
(By the way, to be a bit less awkward, we might from time to time call it a
<emphasis>&apos;PA&apos;</emphasis> box). This chapter will give you some
key concepts like &BA;.</para></highlights>
<sect1 id="bootadmin">
<title>&BA;</title>
<highlights><para>First of all, you must learn what is and how to use &BA; on your
&PA; box, before thinking about doing anything with it.</para></highlights>
<para>&BA; is a <emphasis>firmware</emphasis> application,
used to manage a &PA; machine at an early boot stage,
<emphasis>i.e.</emphasis> when the box has not yet started its
<emphasis>Operating System</emphasis>. It is also known as the
<xref linkend="glossbch" />. Those familiar with the x86 world
will probably see it as a kind of <emphasis>BIOS</emphasis>,
whilst PPC fans might think of it as an equivalent for
<emphasis>Open Firmware</emphasis>.</para>
<para>We named it &BA;
throughout this document since it is the name it is the most common prompt it
will display on
most &PA; machines. You will see through this HOWTO that there
are many references to it, therefore it&apos;s worth
saying that minimalistic &BA; skills are mandatory!</para>
<sect2 id="enterbootadmin">
<title>Entering the &BA; interface</title>
<para>Entering the &BA; management tool isn&apos;t that awful:</para>
<orderedlist numeration="arabic">
<listitem>
<para>Turn your &PA; box on.</para>
</listitem>
<listitem>
<para>During the boot process, the following message will appear
on the current <emphasis>console</emphasis> (see <xref linkend="consoles" />):
<programlisting><computeroutput>
Searching for Potential Boot Devices.
To terminate search, press and hold the ESCAPE key.
</computeroutput></programlisting>
When this message is displayed, press and hold the <keycap>Esc</keycap> key
until an option menu appears. This can take a while, be patient. On recent
machines, pressing any key interrupts the boot process as well.</para>
</listitem>
<listitem>
<para>By default, you should enter the &BA; console.
Though on some 715s and 725s, an option menu looking like this may be shown:
<programlisting><computeroutput>
b) Boot from specified device
s) Search for bootable devices
a) Enter Boot Administration mode
x) Exit and continue boot sequence
?) Help
Select from menu:
</computeroutput></programlisting>
Type &apos;<keycap>a</keycap>&apos; and hit <keycap>Enter</keycap> to enter
Boot Administration mode. This will bring up a
&apos;<computeroutput>BOOT_ADMIN&gt;</computeroutput>&apos; prompt.</para>

</orderedlist>
<para>Once you have the &apos;<computeroutput>BOOT_ADMIN&gt;</computeroutput>&apos;
prompt, you can pat yourself on the back: you are in &BA; mode!</para>
<para>As it has been said before, the prompt can differ between machines. On recent ones,
for instance, it looks like that:

Main Menu: Enter command or menu &gt;

<sect2 id="bootadminhelp">
<title>&BA; commands</title>
<para>&BA; is an early boot subsystem (a Boot Console Handler, as said before)
where you can execute a limited set of commands. You should find here everything
you need to know about them.</para>
<para>All HP-PA systems have a <acronym>BCH</acronym>. The display can be different but the idea remains the same.
That&apos;s why the following list is not complete but consistent enough.
Another important thing is that for each command, you have a shorter way
to invoke it. You can see the shortcut shown as uppercase letters in
the command name. Full names will be used in this section.</para>

<para>These commands are the basic ones.</para>
<itemizedlist>
<listitem>
<para><command>boot</command> may be followed by an argument
which indicates the path you want to boot. The path should be
the definition of a device like for example
<computeroutput>FWSCSI.6.0</computeroutput> or
<computeroutput>PRI</computeroutput> if you have set this
variable correctly. Usually defaults to <computeroutput>PRI</computeroutput>.</para>
</listitem>
<listitem>
<para><command>path</command> displays or sets the current paths.
Invoked with only one argument it will display the current path of the
entity passed as argument: <command>path alt</command> will display the
current alternative boot path. <command>path pri fwscsi.6.0</command> will
setup the primary boot path as the device attached to Fast and Wide SCSI
controller with ID 6 and LUN 0. You can also set and display the paths
of console (graphics/serial) and keyboard (ps2/hil/usb).</para>
</listitem>
<listitem>
<para><command>search</command> is a very useful command.
It automagically checks all possible boot devices and displays
these bootable paths. In several firmware versions, it links them
to a shortcut (like <computeroutput>P0</computeroutput>). It can even search
the LAN, if the box is able to boot it. Some firmware revisions allow you
to restrain the search path like: <command>search lan</command> or
<command>search disk</command>.</para>

</para></highlights>
<para>
In order to boot your &PA; system with the &PL; kernel,
you must first set up a <emphasis>console</emphasis>.
A <emphasis>console</emphasis> is basically the device where the kernel
(and the firmware) will display its output, and where
input can by sent to control the system at an early boot stage.
You can use either <emphasis>graphic console</emphasis>, which requires
having a monitor and a keyboard attached to the system,
or <emphasis>serial console</emphasis>, which allows serial line
communication between the system and another Linux machine,
or any VT system.
</para>
<note><para>Please note that the firmware console and kernel console
are not necessarily the same. For instance, it is possible to
interact with &BA; using keyboard &amp; monitor, and once &PL; is up,
to have kernel output sent to serial port only. By default,
<xref linkend="glosspalo" /> will try to use firmware console as the
kernel one.
</para></note>
<tip><para>
Workstations usually boot in graphic mode, whereas servers
boot in serial mode. Some boxes will also automatically switch
to serial if no keyboard is connected, or if you hold down
<literal>TOC</literal> switch while powering the system on.
</para></tip>

If you don&apos;t know what the actual console of your box is,
it&apos;s quite simple: find the place where first output is sent when
the box is turned on (serial line or monitor output, if any), that is
the console.

<title>Using graphic console</title>
<caution><para>
To use the graphic console, you must first ensure that
the Linux kernel supports your system&apos;s graphic card.
</para></caution>
<para>
There are two ways to deal with the graphic console.
If you think about bug-reporting any trouble, you must know how to
differentiate both. First, the <emphasis>STI</emphasis> console is
the classical video text console, like <emphasis>VGA</emphasis> on a
common PC for example. This name is due to the fact that each &PA;
box with graphical capabilities features the <xref linkend="glosssti" />
which defines some standardized ways to access the video memory.
The other graphic console is the well known
<emphasis>framebuffer</emphasis> console (which on
HP-PA uses STI in a special manner, hence the name
<emphasis>STIfb</emphasis>). In this case, when booting,
you will see a characteristic little penguin appearing on
the top-left corner. This is the easiest way to differentiate
the two graphic modes.
</para>
<para>
Obviously, if you can use graphic console, it is the easiest way to proceed.
Nevertheless, you must be sure that your hardware is supported.
</para>
<important><para>
All HP-provided graphics cards can deal with <xref linkend="glosssticon" />,
but not all of them are <xref linkend="glossstifb" /> supported in Linux.
This is especially true for Vis-FX cards that can only be used through STIcon.
</para></important>
</sect2>
<sect2 id="serialconsole">
<title>Using serial console</title>
<para>
The serial console is a good way to obtain all console messages,
including the <link linkend="glossbch"><acronym>BCH</acronym></link> ones.
It is very useful for bug reports, as its output can be easily dumped.
Moreover, most of the &PA; servers can only be managed with serial console.
</para>
<note><para>
The only cases where serial console <emphasis>HAS TO</emphasis> be used is
either if you don&apos;t have a monitor handy, or if the machine doesn&apos;t
support graphics. It is also possible that the kernel can <emphasis>NOT</emphasis>
handle some specific graphics hardware present in the machine, but that is
pretty rare (<link linkend="glosssticon">STIcon</link> should work everywhere).

<title>Serial Cable</title>
<para>
To connect a &PA; machine to a PC&apos;s RS232 port, you need a
9-pin-to-9-pin female plugs null-modem cable.
You should be able to obtain such a cable at your local computer
hardware reseller.
Obviously, you can also choose to connect the other end of the
cable to a terminal (in this case it will probably need
a 25-pin male plug). Anyway, the most practical method is
to connect it to another box running <command>minicom</command>

prepares and updates bootable media such as hard disk drives.
</para></highlights>

The &PO; boot loader executable is stored in a file called

(See <link linkend="glossipl">the glossary</link>).
The boot media management tool is called &PO;, which
stands for &PL; LOader, just as on x86 the boot media
management tool is called <application>LILO</application>.
</para>
<para>
Even though &PO; is much alike <application>LILO</application>
(both have a userland application and a boot loader executable),
it&apos;s worth mentioning that &PO; doesn&apos;t usually need to be called
every time you build and install a new kernel, as
<application>LILO</application> does<footnote id="ftn-compare-po-lilo">
<para>For the knowledge addict:
&PO; can actually access and read ext2/ext3 filesystem, and therefore follow symlinks,

The main idea is to boot a kernel, passing it all needed parameters.
This is what the <emphasis>boot loader</emphasis> part of &PO; does
(see <xref linkend="paloearlyboot" />).
Once it has been called by the <emphasis>firmware</emphasis>,
it will load the Linux Kernel in memory, passing to it the given
arguments, and tell the processor to branch to its entry point.
This will begin the execution of the kernel on the &PA; computer.

The &PO; management tool can transform the usual

However, it can also make a hard disk drive bootable, specifying

We are going to see all these points precisely.

What must be kept in mind is that <filename>vmlinux</filename>

<title>Making a <filename>lifimage</filename> with <literal>RAMDISK</literal></title>
<para>
First things first: when should you walk this way?
</para>
<para>
At an earlier stage of the &PL; project, the <filename>lifimage</filename>
was very useful. In fact, simply putting this file in a boot server
tree allows you to boot your PA box using the <command>boot lan</command>
instruction without any further involvement
(see <xref linkend="bootnetwork" />).
The main advantage of a <literal>RAMDISK</literal> is that it unpacks
its own file system in RAM, and therefore is completely independent
of the machine I/O capabilities (hard drives, etc). The main drawback
is that you have to build your own <literal>RAMDISK</literal> if
you have memory constraints or need some customized files. Now, let&apos;s see
how to obtain a <filename>lifimage</filename> with <literal>RAMDISK</literal>.
</para>
<para>
We assume you got the latest source of the &PL; kernel tree
(to which we&apos;ll refer below as the
&quot;<filename class="directory">linux/</filename> directory&quot;),
and that you are somewhat familiar with kernel configuration. Check
<xref linkend="kernelconf" /> for &PA; specific options.
Mainly, you will need a (cross-)compiler, the
<filename class="directory">linux/</filename> directory and the &PO;
package installed. If you do not have it, run as
<emphasis>root</emphasis> <command>apt-get install palo</command>.
Everything can also be found at
<ulink url="http://www.parisc-linux.org/">http://www.parisc-linux.org/</ulink>.
Go through the kernel configuration step.
Then, run <command>make palo</command> and if &PO; is installed,
the following message should appear at the end of the compilation:
<programlisting>
A generic palo config file (./palo.conf) has been created for you.
You should check it and re-run "make palo".
WARNING: the "lifimage" file is now placed in this directory by default!
</programlisting>
So, edit the <filename>palo.conf</filename> file:
<programlisting>
# This a generic Palo configuration file. For more information about how
# it works try 'palo -?'.
#
# Most people using 'make palo' want a bootable file, usable for
# network or tape booting for example.
--init-tape=lifimage
--recoverykernel=vmlinux
########## Pick your ROOT here! ##########
# You need at least one 'root='!
#
# If you want a root ramdisk, use the next 2 lines
# (Edit the ramdisk image name!!!!)
--ramdisk=ram-disk-image-file
--commandline=0/vmlinux HOME=/ root=/dev/ram initrd=0/ramdisk
# If you want NFS root, use the following command line (Edit the HOSTNAME!!!)
#--commandline=0/vmlinux HOME=/ root=/dev/nfs nfsroot=HOSTNAME ip=bootp
# If you have root on a disk partition, use this (Edit the partition name!!!)
#--commandline=0/vmlinux HOME=/ root=/dev/sda1
</programlisting>
As you can see, the <literal>RAMDISK</literal> mode is the default. The string
<replaceable>ram-disk-image-file</replaceable> should give to &PO; the path
of your <literal>RAMDISK</literal> file.
You shouldn&apos;t change anything else to this file.
After editing <filename>palo.conf</filename>, you can run
<command>make palo</command> again. The result, a <filename>lifimage</filename>
file, is waiting for you in the <filename>linux/</filename> directory.
</para>
</sect2>
<sect2 id="lifimagewithnfsroot">
<title>Making a <filename>lifimage</filename> with <literal>NFSROOT</literal></title>
<para>
This method is widely used because the kernel and the file system
are directly accessible on your boot server.
It is also very easy to test a new kernel.
You just have to generate the kernel and put it in the correct directory.
When starting up, the PA box will boot the new kernel by typing <command>boot lan</command>
in &BA;.
Finally, it is the only way to go for systems which I/O devices are not supported
(such as E class, by the writing of this document).
</para>
<para>
Enabling <literal>NFSROOT</literal> support is easier than
<literal>RAMDISK</literal>. You have to edit <filename>palo.conf</filename>
to specify the boot server IP address instead of the string
<replaceable>HOSTNAME</replaceable>.
For instance, if your server has 10.10.10.2 as its IP address,
then the <filename>palo.conf</filename> file should contain:
<programlisting>
# This a generic Palo configuration file. For more information about how
# it works try 'palo -?'.
#
# Most people using 'make palo' want a bootable file, usable for
# network or tape booting for example.
--init-tape=lifimage
--recoverykernel=vmlinux
########## Pick your ROOT here! ##########
# You need at least one 'root='!

# If you want a root ramdisk, use the next 2 lines
# (Edit the ramdisk image name!!!!)
#--ramdisk=ram-disk-image-file
#--commandline=0/vmlinux HOME=/ root=/dev/ram initrd=0/ramdisk
# If you want NFS root, use the following command line (Edit the HOSTNAME!!!)
--commandline=0/vmlinux HOME=/ root=/dev/nfs nfsroot=10.10.10.2 ip=bootp
# If you have root on a disk partition, use this (Edit the partition name!!!)
#--commandline=0/vmlinux HOME=/ root=/dev/sda1
</programlisting>
If you have another IP, this field must be filled in with the correct data.
You shouldn&apos;t change anything else to this file.
After having properly configured <filename>palo.conf</filename>,
you can go into the <filename class="directory">linux/</filename>
directory and issue a <command>make palo</command>.
The result, a <filename>lifimage</filename> file, is as usual waiting for
you in the <filename class="directory">linux/</filename> directory.

<para>
To setup a bootable hard disk, you have to partition it properly
(that is, if you want to use it as your primary boot device).
This implies that this step can only be achieved either if you have already
booted a minimal system on your &PA; box (from CD or network,
see <xref linkend="bootsolutions" />), or if you intend to prepare your hard
disk using another computer than the target one (which can be useful to unpack
and setup a downloaded file system for a slow box, for example).
The point of this HOWTO is not to teach you how to use <command>fdisk</command>
and friends, so here are the few things you HAVE TO know:
</para>
<itemizedlist>
<listitem>
<para>
A partition entirely contained within the first 2GB of your target device has
to be of partition type &apos;<computeroutput>f0</computeroutput>&apos;,
which is the reserved partition type for &PO; boot loader.
</para>
</listitem>
<listitem>
<para>
There are two ways to use &PO;: the old scheme (available on all versions),
in which that partition will only store configuration and recovery kernel;
and the new scheme (available since &PO; 1.5), in which that partition will
be formatted as ext2 or ext3 and mounted in <filename class="directory">/boot</filename>.
</para>
</listitem>
<listitem>
<para>
In the first case, the partition does not need to be huge. This is were &PO;
will save its configuration, recovery kernel(s) - about 5MB each - and optional
recovery ramdisk, so 32MB seem far sufficient.
</para>
</listitem>
<listitem>
<para>
Alternatively, in the second case, since you will use it as
<filename class="directory">/boot</filename>, you should size it decently.
100MB is a good cut.
</para>
</listitem>
</itemizedlist>
<warning><para>
Beware! The <filename>vmlinux</filename> file that will be actually booted
has also to be located within the first 2GB of the hard disk.
We strongly recommend to either (in the <emphasis>old</emphasis> scheme) create
a separate <filename class="directory">/boot</filename> partition at the beginning
of the disk (unless you plan to boot recovery kernels every time), or use the
<emphasis>new</emphasis> scheme and mount the &PO; partition as
<filename class="directory">/boot</filename>, because if ever your vmlinux binary
gets physically stored past the first 2GB of the disk
(like when filling up &apos;/&apos; with data), the box won&apos;t boot anymore.
</para></warning>
<para>
In fact, this third usage of &PO; is the most common as the default
<filename>/etc/palo.conf</filename> makes it easy to configure.
</para>

</para>
<itemizedlist>
<listitem>
<para><parameter>recoverykernel</parameter> is (as the name suggests)

going to write on (and erase the content of) the &apos;<literal>f0</literal>&apos;
partition of this device, which has to exist.
</para>
</listitem>
<listitem>
<para><parameter>commandline</parameter>:
the first digit is the number of your ext2/ext3 partition where the
kernel file is located, as reported by <command>fdisk</command>.
Logically, the next string is the absolute path to the kernel
<emphasis>from the root of THIS partition</emphasis>
<footnote id="kpath"><para>Example: /boot is mounted from a separate partition,

From a &L; point of view, the absolute path of the file is
<filename>/boot/vmlinux</filename>, but from a <emphasis>partition</emphasis>
point of view, it is <filename>/vmlinux</filename>. Therefore,
the commandline will start with &quot;<literal>4/vmlinux</literal>&quot;.
We hope that&apos;s clear enough!</para></footnote>.
The following space separated parameters (do NOT use any quotation
mark!) will be passed to the kernel as its arguments. <emphasis>e.g.</emphasis>:
<literal>HOME=</literal> and <literal>TERM=</literal> are
environmental parameters passed to <command>init</command>

<literal>root=</literal> tells the kernel which partition it

console (if enabled in the kernel, see <xref linkend="kernelconf" />)
has been added, using <literal>console=ttyB0</literal>.
Recent versions of &PO; auto detect the right console path
(except for <acronym>MUX</acronym>), and can figure out whether
a 32bit or 64bit kernel should be used. If not, please mail
to the mailing list. Last but not least, if you are using
&D; 2.6 kernels, you will also need to add
<literal>initrd=X/path/to/initrd</literal>, following the same
rules as for the kernel path<footnoteref linkend="kpath" />, see above.

According the above <command>fdisk</command> example, we want to use
<filename class="devicefile">/dev/sda3</filename> as our root partition. Thus,
the configuration file should look like that:
<programlisting>
# The following arguments are set up for booting from /dev/sda, specifically
# mounting partition 3 as root, and using /boot/vmlinux as both the

<title>The new scheme: mounted partition</title>
<highlights><para>
Following is a practical example using the new way of doing things, by using a
formatted &PO; partition. That scheme should be the preferred one for new installations.
</para></highlights>
<para>
Looking at the previous example (<xref linkend="palooldscheme" />), very little things
need to be changed. Essentially, if you had the need for a separate <filename
class="directory">/boot</filename> partition, it will be gone in the scheme detailed
below. The configuration for &PO; will be a little bit different as well, but that&apos;s
about it.
</para>
<para>
Here is the output of <command>fdisk</command> which represents
the hard drive of a box with 100MB &PO; space (which will be mounted as <filename
class="directory">/boot</filename>), 128MB swap space
and about 1GB &apos;<literal>/</literal>&apos; partition (bear in mind that the
<literal>f0</literal> partition must still be wholy contained within the first 2GB
of the disk):
</para>
<programlisting><computeroutput>
bash# fdisk -l /dev/sda
Disk /dev/sda: 133 heads, 62 sectors, 1017 cylinders
Units = cylinders of 8246 * 512 bytes

/dev/sda1 * 1 26 100461 f0 Linux/&PA; boot
/dev/sda2 27 36 123690 82 Linux swap
/dev/sda3 37 277 917889 83 Linux
</computeroutput></programlisting>
<para>
Now let&apos;s deal with &PO; configuration. Contrary to the previous example, there
are far less options to put in the configuration file, and the setup is a single step
operation: the <emphasis>initialization</emphasis> step, which needs only to be done
once.
</para>
<para>
To initialize for the first time the &PO; partition as something the Linux system
can understand (<literal>ext2</literal> or <literal>ext3</literal> filesystem), you need
to run the following command (as <literal>root</literal>):
</para>
<programlisting>
&prompt; <command>palo</command> <userinput>--format-as=<replaceable>N</replaceable> --init-partitioned=<replaceable>target_disk</replaceable></userinput>
</programlisting>
<para>
Where <replaceable>N</replaceable> is either <literal>2</literal> for <literal>ext2</literal>
or <literal>3</literal> for <literal>ext3</literal>, and <replaceable>target_disk</replaceable>
is the device which contains the &PO; partition, <filename class="devicefile">/dev/sda</filename>
in the current example. Continuing with this example, assuming we want an <literal>ext3</literal>
partition we would use:
</para>
<programlisting>
&prompt; <command>palo</command> <userinput>--format-as=3 --init-partitioned=/dev/sda</userinput>
</programlisting>
<warning><para>
Do <emphasis>NOT</emphasis> use <command>mkfs</command> or <command>mke2fs</command>
to generate the filesystem on this partition. &PO; marks blocks as used where the boot loader
portion of &PO; is stored on disk. These tools don&apos;t know about &PO; boot loader!
</para></warning>
<note><para>
This needs to be run only once for it will erase any existing data on the
<literal>f0</literal> partition.
</para></note>
<para>
Finally, we need to tell &PO; about the partition, how we want it to be used, and
how we don&apos;t want it to be erased everytime &PO; is being run. Thus, keeping in sync
with our current example,
the configuration file should look like that:
<programlisting>
# The following arguments are set up for booting from /dev/sda, specifically
# mounting partition 3 as root and booting the vmlinux file in /dev/sda1, palo
# partition formatted as ext3.
--update-partitioned=/dev/sda --format-as=3
--commandline=1/vmlinux root=/dev/sda3
</programlisting>
</para>
<para>
As one can see, since we will be storing our kernels directly on the <literal>f0</literal>
partition, we tell &PO; to load them from it (hence the <literal>1</literal> in the
<literal>commandline</literal> argument.
</para>
<note><para>
In the previous section (<xref linkend="palooldscheme" />) we dealt with the
<parameter>init-partitioned</parameter> parameter. Here, we use
<parameter>update-partitioned</parameter> instead, which, contrary to the former,
tells &PO; to not erase the content of the partition when run<footnote><para>The
<parameter>format-as</parameter> switch is a bit misleading. When used with
<parameter>init-partitioned</parameter> it is meant to tell which filesystem to format
the new partition, but with <parameter>update-partitioned</parameter>, it is meant to
tell &PO; which filesystem is used on the already formatted partition.</para></footnote>.

<title>The theory</title>
<para>
You have setup everything, rebooted your box, and suddenly you
want to change something to the kernel boot arguments,
or even boot another kernel. Damn it! How could you,
now that the box is booting? Well, stay calm and relax,
have a deep breath, we have the solution!
Unfortunately, by the time you&apos;ll learn about it, your box
will have finished booting ;o)
</para>
<para>
First, you must learn how to interact with &PO; during the startup sequence.
You have to enter &BA;, as explained in <xref linkend="enterbootadmin" />.
For some old models (up to 712 or so), you must add the
<parameter>ipl</parameter> (or <parameter>isl</parameter>) string to
your boot command in the &BA; console:
<programlisting><computeroutput>BOOT_ADMIN&gt; </computeroutput>boot pri ipl</programlisting>
On most &PA; boxes, the system will ask you if you want to interact
with <emphasis>IPL</emphasis> anyway. You just have to answer
&quot;<keycap>y</keycap>&quot; and hit <keycap>Enter</keycap>.
You will then end up to &PO; configuration display, with the list
of all parameters and their corresponding numbers.
</para>
<para>
You just have to enter the number corresponding to the
parameter you want to change.
Hit <keycap>Enter</keycap>, modify it and validate the
changes by hitting <keycap>Enter</keycap> again.
The system will redisplay the new list.
This modification is not permanent<footnote><para>
To save your changes, you will have to run <command>/sbin/palo</command>
when your system will be up and running,
and it will write on the disk all the parameters contained in
the configuration file, (<filename>/etc/palo.conf</filename>), which
you will have properly modified if needed.</para></footnote>!
If you want to add a supplementary parameter, select any one
and write yours on the editing line, beginning with a space:
<programlisting>
&lt;#&gt; edit the numbered field
'b' boot with this command line
'r' restore command line
'l' list dir
? 0
3/boot/vmlinux initrd=3/initrd.img
</programlisting>
After validation, the list will count one more parameter.
If you want to delete one, select it and erase the complete entry.
You will see that the list counts one less parameter.

<title>A complete example</title>
<highlights><para>
This example has been suggested by Michael Damaschke. We will use notions
explained in <xref linkend="bootadmin" /> and <xref linkend="palotheory" />,
and refer to concept such as <emphasis>console</emphasis>, seen in
<xref linkend="consoles" />.
So, let&apos;s go for the story of the happy &PL; user booting a kernel,
also called &quot;<emphasis>I don&apos;t know how to configure my workstation
to use the kernel I want during boot sequence!</emphasis>&quot;.
</para></highlights>
<para>
After switching your workstation on, a message on the
console will tell you that the workstation is about to start
automatically the boot sequence, except if you hold the
<keycap>Esc</keycap> key to stop the auto-booting process.
This is a very difficult step: you must hold the
<keycap>Esc</keycap> key down ;o)
</para>
<note><para>
Depending on your model, you might need to press this key
during a quite long time.
</para></note>
<tip><para>
In some cases when using graphic console, the monitor can be
too slow to trigger on, and won&apos;t allow you to see the
warning message. A good workaround is to keep a close eye on
the keyboard&apos;s lights: when they all blink at once, this is
the right time to press and hold the <keycap>Esc</keycap> key.
If you still have troubles, please refer to <xref linkend="consoles" />.
</para></tip>
<para>
There are a few different ways to get access to
&BA; (see <xref linkend="enterbootadmin" />).
If you have an old box, you will see an information message displayed,
where the workstation&apos;s firmware tells you that it will
start searching for all bootable devices,
or that you can break this by holding down the <keycap>Esc</keycap> key.
This is the same procedure as just mentioned, you must
press the <keycap>Esc</keycap> key.
</para>
<para>
As usual, on some machines you might then get a menu where you should press the
<keycap>a</keycap> key followed by <keycap>Enter</keycap>.
You are now facing the deadly &apos;<computeroutput>BOOT_ADMIN&gt;</computeroutput>&apos;
prompt :^). First, we will turn off <literal>auto boot</literal>
process by entering the following lines:
</para>
<programlisting><computeroutput>BOOT_ADMIN&gt; </computeroutput>auto boot off</programlisting>
<para>
then hit <keycap>Enter</keycap> to validate. This will prevent the
box from further attempts at auto-booting. In other words, you won&apos;t
have to stop the boot process with <keycap>Esc</keycap>, it will stop
on its own on subsequent reboots and wait for your instructions.
</para>
<para>
Now, you must tell the system from which boot device you
would like to boot. If it&apos;s a hard drive, it must have a
&apos;<literal>f0</literal>&apos; partition at the beginning
(see <xref linkend="bootsolutions" />).
</para>
<para>
In this example, the old kernel is <filename>vmlinux</filename> and
the new one is <filename>vmlinux-2.4.17-pa3</filename>.
The chosen SCSI boot device is designed by:
<computeroutput>
SCSI.<replaceable>X</replaceable>.0,
</computeroutput>
where <replaceable>X</replaceable> is the SCSI-ID of the disk you
want to boot from<footnote><para>For those who wonder what the final
0 means, it&apos;s the device LUN. Since most SCSI devices have only
one LUN (especially disks), you can safely use 0 as in this
example.</para></footnote>. <emphasis>e.g.:</emphasis>
</para>
<programlisting><computeroutput>BOOT_ADMIN&gt; </computeroutput>boot SCSI.5.0</programlisting>
<para>
At the end of the previous command line, you must add the
<parameter>IPL</parameter> token if you have a HP 9000/7xx
system to specify that you want to interact with
<application>IPL</application>. If you have a more
recent hardware, the system will ask if you want to
interact with <application>IPL</application> anyway:
</para>
<programlisting><computeroutput>Interact with IPL (Y or N)?&gt;</computeroutput></programlisting>
<para>
Say <keycap>Y</keycap> and hit <keycap>Enter</keycap>.
Now, you can manually configure the &PO; boot parameters.
A new menu is displayed, where you can configure on line
&apos;<computeroutput>0</computeroutput>&apos; (selected by default)
the boot partition number, and the path of your boot kernel.

To build a Linux kernel, you need a compiler and the kernel source.
The first element is not a trivial thing to find because it
depends on how you want to build your kernel.
The second is easier since it can be found at
<ulink url="http://cvs.parisc-linux.org/"> the official CVS site</ulink>.
First, we will discuss about <command>GCC</command> compiler.
Then, the preparation of the build will be explained.
The last paragraph will deal with the installation of this new kernel.

You can build the kernel directly on your own &PA; box (<emphasis>self-hosted</emphasis>

But on old systems, you may prefer to use another - faster - non &PA; computer
to compile your kernel (<emphasis>cross-compilation</emphasis>). We will see the
two possibilities.
</para></highlights>
<note><para>
By the time version 1.0 of this howto was released, only gcc-3.0.X was able
to build working kernels. There was a bug in more recent versions that made
the box crash when network activity occurs. It should be fixed by now, so
using the latest version of gcc should be fine. If ever the above mentioned
bug occurs, you&apos;ll know what&apos;s wrong. Anyway, if you want to build
any kernel after 2.6.12-rc3, you will need at least <command>gcc-3.3</command>.

The best way to obtain appreciable performances is to get a well
configured kernel. For the &PA; platform, <command>make oldconfig</command>
is a kind of default setup. If you want to make your own kernel,
the first step is to know what hardware you have. The best way to
grab useful info is to look at your box and find a maximum of data
(model name, partnumber, chipsets, and so on). If you have already
booted your box, you can take a look at <command>dmesg</command>
output. Then, go to the <ulink url="http://hwdb.parisc-linux.org/">official

<title>Configuring 2.6 kernels</title>
<highlights><para>
Here is a brief list of architecture dependent menus for 2.6 kernels.
You should take a look at them, to see if the values set match
your hardware:
</para></highlights>
<itemizedlist>
<listitem>
<para><emphasis>Processor type and features</emphasis> - indicates your CPU model
and some specific features such as SMP or Discontigmem support</para>
</listitem>
<listitem>
<para><emphasis>Bus options</emphasis> - tells you what bus support is going to be
enabled in your kernel (U2/Uturn, USC/GSC/HSC, Lasi, Wax, Dino, LBA/Elroy, SuperIO)</para>

<listitem>
<para><emphasis>PA-RISC specific drivers</emphasis> - enables/disables some &PA; specific
drivers, such as LED support, GSP and Stable Storage support.</para>
</listitem>
</itemizedlist>
<para>
As you can see, menus specifically concerned by &PA; hardware are not
that numerous, and everything else is much generic by now. Still,
you must configure the kernel accordingly to what you plan to use
this box for and what features you want supported. Many other drivers are found in
their respective submenus, such as SCSI, with the Zalon, Lasi SCSI and SYM2 drivers being
there, or the Framebuffer devices (STI) in the Graphics Support menu, or the sound drivers
(Harmony and AD1889) in the Sound menu. Help is often provided, feel free to look at it.

<note><para>
Most of what was said for 2.4 is somewhat still applicable to 2.6.
</para></note>
<!-- XXX improve? -->
</sect2>
</sect1>
<sect1 id="kernelinstall">
<title>Kernel installation</title>
<para>
If you have made a native build on the box you wish to install, you can setup
the new kernel as follows:
within the kernel source tree <filename>linux/</filename>, as <literal>root</literal> execute:
<programlisting>
&prompt; <command>cp vmlinux /boot/vmlinux-<replaceable>[kernelversion]</replaceable></command>
&prompt; <command>cp System.map /boot/System.map-<replaceable>[kernelversion]</replaceable></command>
&prompt; <command>cp .config /boot/config-<replaceable>[kernelversion]</replaceable></command>
</programlisting>
Though it is not mandatory, we suggest you to replace
<replaceable>[kernelversion]</replaceable> by the version of the
kernel you built, <emphasis>e.g.</emphasis>:
<filename>vmlinux-2.4.18-pa44</filename>. This will help you
dealing with multiple kernel versions on the same machine.
The same applies to <filename>.config</filename>.
It is not needed to have a working kernel, though it might
be very helpful when configuring a new one.
Now, do <command>cd /boot</command>, make sure that
<filename>vmlinux</filename> is a symbolic link to another
file, as in the following example:
<programlisting>
&prompt; <command>ls -l vmlinux</command>
<computeroutput>lrwxrwxrwx 1 root root 35 Jun 23 01:38 vmlinux -&gt; vmlinux-2.4.18-64-SMP</computeroutput>
</programlisting>
Make sure to remember the name of the kernel actually running
on your box if ever the new one won&apos;t work properly.
You are now able to ask &PO; to boot on it if needed
(see <xref linkend="palo" /> for more information).
Now do the following:
<programlisting>
&prompt; <command>rm -f vmlinux</command>
&prompt; <command>ln -s vmlinux-<replaceable>[kernelversion]</replaceable> vmlinux</command>
&prompt; <command>sync</command>
</programlisting>
If you want to boot from network you can forget all this,
as you will need to set &PO; as explained in the
<xref linkend="paloappusage" />, and run <command>make palo</command>
to create the bootable <emphasis>lifimage</emphasis>.
</para>
<para>
If you have made a cross-compiled build or built a kernel on a
PA box which is not the one you wish to install,
you have to find a way to put <filename>vmlinux</filename>,
<filename>System.map</filename> and eventually <filename>.config</filename>
in <filename class="directory">/boot/</filename> as mentioned before.
You can use the network (like <command>ftp</command>)
or a CD to do so, or even direct copy to the hard disk drive.

&PO; was first setup to boot the kernel file <filename>vmlinux</filename>
located on the third partition of the SCSI device ID 5 LUN 0.
(We know this since we have asked &BA; to boot on this device).
But we wanted another kernel this time.
We have pressed the <keycap>Enter</keycap> key (to validate the default
choice &apos;<computeroutput>0</computeroutput>&apos;)
and modified the text to match our needs, here
<filename>vmlinux-2.4.17-pa3</filename>. We have also
added an <computeroutput>initrd=0/root.bin</computeroutput> argument
to the command line. We have validated our changes
by hitting the <keycap>Enter</keycap> key.
Finally we have decided that we didn&apos;t want this
additional argument, so we have selected it and erased it.
At the end it asked again which field we wanted to edit, we
just typed &apos;<computeroutput>b</computeroutput>&apos; instead
of any number and hit <keycap>Enter</keycap> to boot our new kernel.
