+There are three basic variations of Debian Install CDs.
+The <emphasis>Business Card</emphasis> CD has a minimal installation
+that will fit on the small form factor CD media.
+It requires a network connection in order to install the rest of the
+base installation and make a usable system.
+The <emphasis>Network Install</emphasis> CD has all of the packages
+for a base install but requires a network connection to a Debian
+mirror site in order to install the
+extra packages one would want for a complete system .
+The set of Debian CDs can install a complete system from the wide
+range of packages without needing access to the network.

+The IA-64 architecture uses the next generation Extensible Firmware Interface
+(EFI) from Intel.
+Unlike the traditional x86 BIOS which knows little about the boot
+device other than the partition table and Master Boot Record (MBR),
+EFI can read and write files from FAT16 or FAT32 formatted disk
+partitions.
+This simplifies the often arcane process of starting a system.
+The system boot loader and the EFI firmware that supports it have
+a full filesystem to store the files necessary for booting the
+machine.
+This means that the system disk on an IA-64 system has an additional
+disk partition dedicated to EFI instead of the simple MBR or boot
+block on more conventional systems. 
+
+</para><para>
+
+The Debian Installer CD contains a small EFI partition where the
+<command>ELILO</command> bootloader, its configuration file, the installer's
+kernel, and initial filesystem (initrd) are located.
+The running system also contains an EFI partition where the necessary
+files for booting the system reside.
+These files are readable from the EFI Shell as described below.
+
+</para><para>
+
+Most of the details of how <command>ELILO</command> actually loads and
+starts a system are transparent to the system installer.
+However, the installer must set up an EFI partition prior to installing
+the base system.  Otherwise, the installation of <command>ELILO</command>
+will fail, rendering the system un-bootable.
+The EFI partition is allocated and formatted in the partitioning step
+of the installation prior to loading any packages on the system disk.
+The partitioning task also verifies that a suitable EFI partition is
+present before allowing the installation to proceed.
+

+
+The EFI Boot Manager is presented as the last step of the firmware
+initialization.
+It displays a menu list from which the user can select
+an option.
+Depending on the model of system and what other software has been
+loaded on the system, this menu may be different from one system
+to another.
+There should be at least two menu items displayed,
+<command>Boot Option Maintenance Menu</command> and
+<command>EFI Shell (Built-in)</command>.
+Using the first option is preferred, however, if that
+option is not available or the CD for some reason does not
+boot with it, use the second option.
+
+</para>
+
+  <warning>
+  <title>IMPORTANT</title>
+<para>
+The EFI Boot Manager will select a default boot action, typically
+the first menu choice, within a pre-set number of seconds.
+This is indicated by a countdown at the bottom of the screen.
+Once the timer expires and the systems starts the default action,
+you may have to reboot the machine in order to continue the installation.
+If the default action is th EFI Shell, you can return to the Boot Manager
+by running <command>exit</command> at the shell prompt.

+The boot loader will display a form with a menu list and a text
+window with a <classname>Boot:</classname> prompt.
+The arrow keys select an item from the menu and any text typed
+at the keyboard will appear in the text window.
+There are also help screens which can be displayed by pressing
+the appropriate function key.

+
+   <title>Serial Console</title>
+<para>
+You may choose to perform an install using a monitor and keyboard
+or using a serial connection.  To use a monitor/keyboard setup,
+select an option containing the string [VGA console].  To install
+over a serial connection, choose an option containing the string
+[<replaceable>BAUD</replaceable> baud serial console], where
+<replaceable>BAUD</replaceable> is the speed of your serial console.
+Menu items for the most typical baud rate settings on the ttyS0
+device are preconfigured.
+</para>
+<para>
+In most circumstances, you will want the installer to use the same
+baud rate as your connection to the EFI console.  If you aren't
+sure what this setting is, you can obtain it using the command
+<command>baud</command> at the EFI shell.
+</para>
+<para>
+If there is not an option available that is configured for the serial
+device or baud rate you would like to use, you may override the console setting
+for one of the existing menu options.  For example, to use a
+57600 baud console over the ttyS1 device, enter
+<command>console=ttyS1,57600n8</command> into
+the <classname>Boot:</classname> text window.
+</para>
+
+<note><para>
+Most IA-64 boxes ship with a default console setting of 9600 baud.
+This setting is rather slow, and the normal installation process
+will take a significant time to draw each screen.  You should consider
+either increasing the baud rate used for performing the installation,
+or performing a Text Mode installation.  See the <classname>Params</classname>
+help menu for instructions on starting the installer in Text Mode.
+</para></note>

+<warning><para>
+If you select the wrong console type, you

+the display and your input will go dead as soon as the kernel starts,

+text window.
+The kernel version you choose selects the kernel version that will be

+
+<para>
+Booting an IA64 system from the network is similar to a CD boot.
+The only difference is how the installation kernel is loaded.
+The EFI Boot Manager can load and start programs from a server on
+the network.
+Once the installation kernel is loaded and starts, the system install
+will proceed thru the same steps as the CD install with the exception
+that the packages of the base install will be loaded from the network
+rather than the CD drive.

+
+Network booting an ia64 system requires two architecture-specific actions.
+On the boot server, DHCP and TFTP must be configured to deliver
+<command>elilo</command>.
+On the client a new boot option must be defined in the EFI boot manager
+to enable loading over a network.
