Network booting an ia64 system requires two architecture-specific actions.
|
| 19 |
On the boot server, DHCP and TFTP must be configured to deliver elilo.
|
| 20 |
On the client a new boot option must be defined in the EFI boot manager
|
| 21 |
to enable loading over a network.

A suitable TFTP entry for network booting an ia64 system looks something
|
| 28 |
like this:
|
| 29 |
|
| 30 |
<informalexample><screen>
|
| 31 |
|
| 32 |
host mcmuffin {
|
| 33 |
hardware ethernet 00:30:6e:1e:0e:83;
|
| 34 |
fixed-address 10.0.0.21;
|
| 35 |
filename "elilo.efi";
|
| 36 |
}
|
| 37 |
|
| 38 |
</screen></informalexample>
|
| 39 |
|
| 40 |
Note that the goal is to get elilo.efi running on the client.
|
| 41 |
|
| 42 |

Create an ia64/ subdirectory in your tftpboot directory, and populate it with
|
| 45 |
the vmlinuz and initrd.gz files from the Debian installer netboot directory.
|
| 46 |
|
| 47 |
</para><para>
|

Copy elilo.efi from an IA-64 machine to your tftpboot directory and make it
|
| 50 |
world readable.
|
| 51 |
This file can usually be found in the elilo package in IA64 distributions,
|
| 52 |
or in /usr/lib/elilo or in a subdirectory of /boot/efi.
|
| 53 |
|
| 54 |
</para><para>
|
| 55 |
|
| 56 |
Create an elilo.conf file in your tftpboot directory. This will
|
| 57 |
be loaded by elilo.efi once it is running on the client, and controls what
|
| 58 |
happens next, including the choice of kernel, initrd image, etc. A reasonable
|
| 59 |
example for booting with a serial console might look something like this:
|
| 60 |
|
| 61 |
<informalexample><screen>
|
| 62 |
|
| 63 |
#
|
| 64 |
# elilo.conf for netbooting ia64 client
|
| 65 |
#
|

default=Installer
|

image=ia64/vmlinuz
|
| 69 |
label=Installer
|
| 70 |
initrd=ia64/initrd.gz
|
| 71 |
root=/dev/ram
|
| 72 |
append="ramdisk_size=32768 console=ttyS0,9600n8"
|
| 73 |
read-only
|
| 74 |
|
| 75 |
</screen></informalexample>
|
| 76 |
|
| 77 |
It is possible to have different config files for different clients by naming
|
| 78 |
them using the client's IP address in hex with the suffix .conf instead of
|
| 79 |
elilo.conf. See documentation provided in the elilo package for details.

To configure the client to support TFTP booting, start by booting to EFI and
|
| 86 |
entering the "Boot Option Maintenance Menu".

You should see the new boot option you just created, and
|
| 96 |
selecting it should initiate a DHCP query, leading to a TFTP load of elilo.efi
|
| 97 |
from the server.
