7. For the first boot you will be prompted to complete some post-installation
settings, like the License Agreement, Date and Time, and User Account.
4.4.5 Linux boot process
The Linux boot process on IA-64 systems uses elilo instead of the classic lilo or
grub boot loaders. elilo.conf is a file stored in the root director of the EFI System
Partition.
There is no longer a need for boot loaders because the EFI system can manage
the boot procedure for the different operating systems. The boot loader is helpful,
however, if we need to provide boot parameters to the kernel; for example, if we
want to recover from some special situations by putting parameters to the boot
command line, or we want to boot on initlevel 3 only once and our system is
configured to boot on initlevel 5 by default, etc.
If you do not press any key before the delay estimated on the elilo.conf file, Linux
will start loading automatically. To reduce the delay or remove it completely,
change or remove the corresponding line in elilo.conf.
Example 4-1 shows a typical elilo.conf configuration file. As you can see, the elilo
configuration is very similar to the old lilo configuration. One of the main
advantages of elilo is that you do not need to execute any command to make
your changes active: elilo will automatically take any changes you make on the
elilo.conf file.
Example 4-1 An example of elilo.conf
# ELILO config file
prompt
timeout = 80
read-only
image = /vmlinuz
label = linux
root = 806
initrd = /initrd
append = "hda=ide-scsi"
Once elilo is loaded, select which Linux kernel image you want to load, and the
boot procedure is the same as other Linux startup processes:
1. The Linux kernel image loads on memory.
2. The Setup function is called, enabling basic devices, buses and video.
