I/ Introduction
------------
-This document describes how to use ELILO on for both IA-64 and IA-32 EFI-based platforms.
-This document describes ELILO version 3.4.
+This document describes how to use ELILO on for IA-64, IA-32 and x86_64 EFI-based platforms.
+This document describes ELILO version 3.7.
II/ Command line options
--------------------
for more information on device naming schemes. The slash character '/' can be used as
a directory separator on any file systems including the EFI file system (FAT32).
+ For x86_64:
+ ----------
+ No new options.
III/ Configuration File
------------------
where AABBCCDD is the hexadecimal representation
of the IP address assigned during the DHCP phase.
- 2/ elilo-ia64.conf or elilo-ia32.conf
+ 2/ elilo-ia64.conf or elilo-ia32.conf or elilo-x86_64.conf
The choice depends on the client platform. This step allows
the same DHCP/PXE server to provide files for both types of clients.
the user can also specify a kernel file that is not specified in the config file. In any case,
some of the global options (such as append) are always concatenated to whatever the user type.
+ x86_64 specific options:
+ -----------------------
+ None yet.
IV/ Booting from the local system
-----------------------------
be booted (plain vmlinux will not work). Similarly, existing initial ramdisks can
be used without modifications.
+XIII/ Booting on EFI/x86_64 platforms
+ -----------------------------
+
+ To use elilo on x86_64, you can put it on a floppy and
+ on a FAT32 partition (msdos partition). You can also
+ netboot if your network adapter has support for UNDI/PXE.
+
+ Elilo/x86_64 requires efi64 enabled linux kernel (> 2.6.21).
+ You need to compile the kernel with CONFIG_EFI option.
+ x86_64 platforms with UEFI 2.0 firmware deprecate UGA protocol
+ and therefore only the Graphics Output Protocol (GOP) is supported. For
+ such platforms, the kernel must be configured with EFI_FB option. This
+ will enable early boot messages on the console. The elilo for x86_64
+ attempts to query the firmware for GOP and if it fails it defaults to
+ text mode. Elilo ONLY takes compressed kernel image which are
+ typically obtained via a 'make bzImage'. Plain elf/x86_64 kernel can't
+ be booted (plain vmlinux will not work). Similarly, existing initial
+ ramdisks can be used without modifications.
+
+ The x86_64 implementation converts the EFI memory map into E820 map and
+ passes it in the bootparameter supplied to the OS. For details on
+ bootparameter, see x86_64/sysdeps.h.
