<title>CD Contents</title>
13
There are three basic variations of Debian Install CDs.
14
The <emphasis>Business Card</emphasis> CD has a minimal installation
15
that will fit on the small form factor CD media.
16
It requires a network connection in order to install the rest of the
17
base installation and make a usable system.
18
The <emphasis>Network Install</emphasis> CD has all of the packages
19
for a base install but requires a network connection to a Debian
20
mirror site in order to install the
21
extra packages one would want for a complete system .
22
The set of Debian CDs can install a complete system from the wide
23
range of packages without needing access to the network.
29
The IA-64 architecture uses the next generation Extensible Firmware Interface
31
Unlike the traditional x86 BIOS which knows little about the boot
32
device other than the partition table and Master Boot Record (MBR),
33
EFI can read and write files from FAT16 or FAT32 formatted disk
35
This simplifies the often arcane process of starting a system.
36
The system boot loader and the EFI firmware that supports it have
37
a full filesystem to store the files necessary for booting the
39
This means that the system disk on an IA-64 system has an additional
40
disk partition dedicated to EFI instead of the simple MBR or boot
41
block on more conventional systems.
45
The Debian Installer CD contains a small EFI partition where the
46
<command>ELILO</command> bootloader, its configuration file, the installer's
47
kernel, and initial filesystem (initrd) are located.
48
The running system also contains an EFI partition where the necessary
49
files for booting the system reside.
50
These files are readable from the EFI Shell as described below.
54
Most of the details of how <command>ELILO</command> actually loads and
55
starts a system are transparent to the system installer.
56
However, the installer must set up an EFI partition prior to installing
57
the base system. Otherwise, the installation of <command>ELILO</command>
58
will fail, rendering the system un-bootable.
59
The EFI partition is allocated and formatted in the partitioning step
60
of the installation prior to loading any packages on the system disk.
61
The partitioning task also verifies that a suitable EFI partition is
62
present before allowing the installation to proceed.
66
The EFI Boot Manager is presented as the last step of the firmware
68
It displays a menu list from which the user can select
70
Depending on the model of system and what other software has been
71
loaded on the system, this menu may be different from one system
73
There should be at least two menu items displayed,
74
<command>Boot Option Maintenance Menu</command> and
75
<command>EFI Shell (Built-in)</command>.
76
Using the first option is preferred, however, if that
77
option is not available or the CD for some reason does not
78
boot with it, use the second option.
83
<title>IMPORTANT</title>
85
The EFI Boot Manager will select a default boot action, typically
86
the first menu choice, within a pre-set number of seconds.
87
This is indicated by a countdown at the bottom of the screen.
88
Once the timer expires and the systems starts the default action,
89
you may have to reboot the machine in order to continue the installation.
90
If the default action is th EFI Shell, you can return to the Boot Manager
91
by running <command>exit</command> at the shell prompt.
95
<sect3 arch="ia64" id="bootable-cd">
96
<title>Option 1: Booting from the Boot Option Maintenance Menu</title>
104
Insert the CD in the DVD/CD drive and reboot the machine.
105
The firmware will display the EFI Boot Manager page and menu after
106
it completes its system initialization.
110
Select <command>Boot Maintenance Menu</command> from the menu
111
with the arrow keys and press <command>ENTER</command>.
112
This will display a new menu.
116
Select <command>Boot From a File</command> from the menu
117
with the arrow keys and press <command>ENTER</command>.
118
This will display a list of devices probed by the firmware.
119
You should see two menu lines containing either the label
120
<command>Debian Inst [Acpi ...</command> or
121
<command>Removable Media Boot</command>.
122
If you examine the rest of the menu line, you will notice that
123
the device and controller information should be the same.
127
You can choose either of the entries that refer to the CD/DVD
129
Select your choice with the arrow keys and press <command>ENTER</command>.
130
If you choose <command>Removable Media Boot</command> the machine
131
will immediately start the boot load sequence.
132
If you choose <command>Debian Inst [Acpi ...</command> instead, it
133
will display a directory listing of the bootable portion of the
134
CD, requiring you to proceed to the next (additional) step.
138
You will only need this step if you chose
139
<command>Debian Inst [Acpi ...</command>.
140
The directory listing will also show
141
<command>[Treat like Removable Media Boot]</command> on the next to
143
Select this line with the arrow keys and press <command>ENTER</command>.
144
This will start the boot load sequence.
151
These steps start the Debian boot loader which will display a
152
menu page for you to select a boot kernel and options.
153
Proceed to selecting the boot kernel and options.
158
<sect3 arch="ia64" id="boot-with-efi">
159
<title>Option 2: Booting from the EFI Shell</title>
162
If, for some reason, option 1 is not successful, reboot the machine
163
and when the EFI Boot Manager screen appears there should be
164
one option called <command>EFI Shell [Built-in]</command>.
165
Boot the Debian Installer CD with the following steps:
172
Insert the CD in the DVD/CD drive and reboot the machine.
173
The firmware will display the EFI Boot Manager page and menu after
174
it completes system initialization.
178
Select <command>EFI Shell</command> from the menu with the arrow keys
179
and press <command>ENTER</command>.
180
The EFI Shell will scan all of the bootable devices and display
181
them to the console before displaying its command prompt.
182
The recognized bootable partitions on devices will show a device name of
183
<filename>fs<emphasis>n</emphasis>:</filename>.
184
All other recognized partitions will be named
185
<filename>blk<emphasis>n</emphasis>:</filename>.
186
If you inserted the CD just before entering the shell, this may
187
take a few extra seconds as it initializes the CD drive.
192
Examine the output from the shell looking for the CDROM drive.
193
It is most likely the <filename>fs0:</filename> device although
194
other devices with bootable partitions will also show up as
195
<filename>fs<emphasis>n</emphasis></filename>.
199
Enter <command>fs<emphasis>n</emphasis>:</command> and press
200
<command>ENTER</command> to select that
201
device where <emphasis>n</emphasis> is the partition number for the
202
CDROM. The shell will now display the partition number as its prompt.
206
Enter <command>elilo</command> and press <command>ENTER</command>.
207
This will start the boot load sequence.
214
As with option 1, these steps start the Debian boot loader which will
215
display a menu page for you to select a boot kernel and options.
216
You can also enter the shorter
217
<command>fs<emphasis>n</emphasis>:elilo</command> command at
219
Proceed to selecting the boot kernel and options.
225

<title>Selecting the Boot Kernel and Options</title>
230
The boot loader will display a form with a menu list and a text
231
window with a <classname>Boot:</classname> prompt.
232
The arrow keys select an item from the menu and any text typed
233
at the keyboard will appear in the text window.
234
There are also help screens which can be displayed by pressing
235
the appropriate function key.
236
The <classname>General</classname> help screen explains the menu
237
choices and the <classname>Params</classname> screen explains
238
the common command line options.
242
<title>Serial Console</title>
244
You may choose to perform an install using a monitor and keyboard
245
or using a serial connection. To use a monitor/keyboard setup,
246
select an option containing the string [VGA console]. To install
247
over a serial connection, choose an option containing the string
248
[<replaceable>BAUD</replaceable> baud serial console], where
249
<replaceable>BAUD</replaceable> is the speed of your serial console.
250
Menu items for the most typical baud rate settings on the ttyS0
251
device are preconfigured.
254
In most circumstances, you will want the installer to use the same
255
baud rate as your connection to the EFI console. If you aren't
256
sure what this setting is, you can obtain it using the command
257
<command>baud</command> at the EFI shell.
260
If there is not an option available that is configured for the serial
261
device or baud rate you would like to use, you may override the console setting
262
for one of the existing menu options. For example, to use a
263
57600 baud console over the ttyS1 device, enter
264
<command>console=ttyS1,57600n8</command> into
265
the <classname>Boot:</classname> text window.
269
Most IA-64 boxes ship with a default console setting of 9600 baud.
270
This setting is rather slow, and the normal installation process
271
will take a significant time to draw each screen. You should consider
272
either increasing the baud rate used for performing the installation,
273
or performing a Text Mode installation. See the <classname>Params</classname>
274
help menu for instructions on starting the installer in Text Mode.
278
If you select the wrong console type, you
279
will be able to select the kernel and enter parameters but both
280
the display and your input will go dead as soon as the kernel starts,
281
requiring you to reboot before you can begin the installation.
286
Consult the <classname>General</classname> help screen for the
287
description of the kernels and install modes most appropriate
288
for your installation.
289
You should also consult <xref linkend="boot-parms"/> below for any additional
290
parameters that you may want to set in the <classname>Boot:</classname>
292
The kernel version you choose selects the kernel version that will be
293
used for both the installation process and the installed system.
294
If you encounter kernel problems with the installation, you may also
295
have those same problems with the system you install.
296
The following two steps will select and start the install:
303
Select the kernel version and installation mode most
304
appropriate to your needs with the arrow keys.
308
Enter any boot parameters by typing at the keyboard.
309
The text will be displayed directly in the text window.
310
This is where kernel parameters (such as serial console
311
settings) are specified.
315
Press <command>ENTER</command>. This will load and start the
317
The kernel will display its usual initialization messages followed
318
by the first screen of the Debian Installer.
327
Proceed to the next chapter to continue the installation where you will
328
set up the language locale, network, and disk partitions.
333
<sect2 arch="ia64" id="boot-tftp"><title>Booting with TFTP</title>
336
Booting an IA64 system from the network is similar to a CD boot.
337
The only difference is how the installation kernel is loaded.
338
The EFI Boot Manager can load and start programs from a server on
340
Once the installation kernel is loaded and starts, the system install
341
will proceed thru the same steps as the CD install with the exception
342
that the packages of the base install will be loaded from the network
343
rather than the CD drive.
347
&boot-installer-intro-net.xml;
351
Network booting an ia64 system requires two architecture-specific actions.
352
On the boot server, DHCP and TFTP must be configured to deliver
353
<command>elilo</command>.
354
On the client a new boot option must be defined in the EFI boot manager
355
to enable loading over a network.

A suitable TFTP entry for network booting an ia64 system looks something

Extract the <filename>netboot.tar.gz</filename> file into the directory used
382
as the root for your tftp server. Typical tftp root directories include
383
<filename>/var/lib/tftp</filename> and <filename>/tftpboot</filename>.
384
This will create a <filename>debian-installer</filename> directory
385
tree containing the boot files for an IA-64 system.
389
<informalexample><screen>
391
# tar xvfz /home/user/netboot.tar.gz

./debian-installer/ia64/
396
</screen></informalexample>
398
The <filename>netboot.tar.gz</filename> contains an
399
<filename>elilo.conf</filename> file that should work for most configurations.
400
However, should you need to make changes to this file, you can find it in the
401
<filename>debian-installer/ia64/</filename> directory.
403
It is possible to have different config files for different clients by naming
404
them using the client's IP address in hex with the suffix
405
<filename>.conf</filename> instead of <filename>elilo.conf</filename>.
406
See documentation provided in the <classname>elilo</classname> package

<title>Configuring the Client</title>
416
To configure the client to support TFTP booting, start by booting to
417
EFI and entering the <guimenu>Boot Option Maintenance Menu</guimenu>.
427
You should see one or more lines with the text
428
<guimenuitem>Load File [Acpi()/.../Mac()]</guimenuitem>. If more
429
than one of these entries exist, choose the one containing the
430
MAC address of the interface from which you'll be booting.
431
Use the arrow keys to highlight your choice, then press enter.
436
Name the entry <userinput>Netboot</userinput> or something similar,
437
save, and exit back to the boot options menu.
442
You should see the new boot option you just created, and selecting it
443
should initiate a DHCP query, leading to a TFTP load of
444
<filename>elilo.efi</filename> from the server.
448
The boot loader will display its prompt after it has downloaded and
449
processed its configuration file.

CD install. Select a boot option as in above and when the kernel
