Booting from a CD-ROM &boot-installer-intro-cd.xml; Not yet written. Booting with TFTP &boot-installer-intro-net.xml; Network booting an ia64 system requires two architecture-specific actions. On the boot server, DHCP and TFTP must be configured to deliver elilo. On the client a new boot option must be defined in the EFI boot manager to enable loading over a network. Configuring the Server A suitable TFTP entry for network booting an ia64 system looks something like this: host mcmuffin { hardware ethernet 00:30:6e:1e:0e:83; fixed-address 10.0.0.21; filename "elilo.efi"; } Note that the goal is to get elilo.efi running on the client. Create an ia64/ subdirectory in your tftpboot directory, and populate it with the vmlinuz and initrd.gz files from the Debian installer netboot directory. Copy elilo.efi to your tftpboot directory and make it world readable. This file can usually be found in the elilo package in IA64 distributions, or in /usr/lib/elilo or in a subdirectory of /boot/efi. A suitable copy is provided in the Debian installer netboot directory. Create an elilo.conf file in your tftpboot directory. This will be loaded by elilo.efi once it is running on the client, and controls what happens next, including the choice of kernel, initrd image, etc. An example file is provided in the Debian installer netboot directory, review the contents and update as needed for your choice of paths, etc. It is possible to have different config files for different clients by naming them using the client's IP address in hex with the suffix .conf instead of elilo.conf. See documentation provided in the elilo package for details. Configuring the Client To configure the client to support TFTP booting, start by booting to EFI and entering the Boot Option Maintenance Menu. Add a boot option. Select the line saying Load File [Acpi()/.../Mac()] and press &enterkey;. Name the entry Netboot or something similar, save, and exit back to the boot options menu. You should see the new boot option you just created, and selecting it should initiate a DHCP query, leading to a TFTP load of elilo.efi from the server.
