* ADD CROSSBUILD
|
||||
* intake edited version of Debian x86x crossbuild patches.
|
||||
* Fixed Makefile clean to include crossbuild envs.
|
||||
* Fixed ia32 system.c compile warning
|
||||
* Simplified efi no GOP warning so it doesnt look like an error.
|
||||
* MAJOR: Fixed Fault crash when EFI memory map changes from under elilo.
|
||||
(from an outside interrupt in this case). When the EFI Memory map
|
||||
changes after elilo has already built boot params to pass to the
|
||||
kernel the EFI call to ExitBootSvcs just prior to boot will fail
|
||||
because elilo has the old map key. This is valid EFI behavior, elilo
|
||||
retries to pick up the new memory map and valid key but had already
|
||||
freed the start params portion of boot params resulting in a NULL
|
||||
DEREF crash reset.
|
||||
* Add console reset call during initialization. thanks A. Steinmetz
|
||||
* minor bugfix, fixed -m option broken. thanks Allan-lsk.
|
||||
* tag 3_16 for release

|
||||
I/ Introduction
|
||||
------------
|
||||
|
||||
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 - 3.14.
|
||||
|
||||
II/ Command line options
|
||||
--------------------
|
||||
|
||||
elilo [-hDpPVvaE] [-d nsec] [-C config] [-i initrd] [-c chooser] [kernel [kernel options...]]
|
||||
|
||||
-h Display a list of all possible command line options.
|
||||
|
||||
-V Print the version number and exit.
|
||||
|
||||
-d nsec Specify the number of 10th of seconds before loading the
|
||||
kernel.
|
||||
|
||||
-C file Specify the config file to use. The default is elilo.conf in the directory
|
||||
that elilo.efi was loaded from.
|
||||
|
||||
-P Verify config file syntax only. this option causes ELILO to
|
||||
parse the config file and generate a report on the console.
|
||||
No kernel is loaded.
|
||||
|
||||
-v Turn on verbose mode. ELILO prints more message about what it
|
||||
is doing. For each occurrence of this option the verbosity level
|
||||
is increased by one. The maximum level is 5.
|
||||
|
||||
-a Always check for alternate kernel image. The default behavior
|
||||
of ELILO is to NOT look for an alternate image. This
|
||||
option overrides this behavior and ELILO is checking for
|
||||
alternate images no matter what. Alternate images are
|
||||
specified using the EliloAlt EFI variable.
|
||||
|
||||
-p force interactive prompt mode. Valid when no kernel image is
|
||||
specified on the command line.
|
||||
|
||||
-D print debug output.
|
||||
|
||||
-E don't force EDD30 variable to TRUE when FALSE.
|
||||
|
||||
-i file Use file as the initial ramdisk (initrd).
|
||||
|
||||
-c name Specify which kernel chooser to use. Default is 'simple', and
|
||||
the only other choice at present is 'textmenu'.
|
||||
|
||||
In addition, elilo supports platform specific options:
|
||||
|
||||
For IA-64:
|
||||
----------
|
||||
-r the kernel image can be relocated if initial load address is not
|
||||
available. This options requires a special version of the kernel.
|
||||
|
||||
-F file will try to load the FPSWA driver indicated by 'file'. Only this file
|
||||
will be attempted. When no specific file is given, elilo will try
|
||||
loading \efi\intel firmware\fpswa.efi from all accessible EFI system
|
||||
partitions.
|
||||
For IA-32:
|
||||
----------
|
||||
no option defined.
|
||||
|
||||
All file names (including the kernel file) can include a device name using the
|
||||
following syntax:
|
||||
|
||||
dev_name:/path/to/my/kernel
|
||||
|
||||
The 'dev_name' component depends on the naming scheme selected and the detected
|
||||
devices for your system. Some choosers may print the information automatically
|
||||
or on demand, see chooser specific documentation for more on this. See README.devschemes
|
||||
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:
|
||||
----------
|
||||
none
|
||||
|
||||
III/ Configuration File
|
||||
------------------
|
||||
|
||||
ELILO supports a config file with options similar to the LILO/x86 boot loader.
|
||||
|
||||
Elilo will use the following sequence (shown in order) when looking for its config
|
||||
file when none is specified on the command line:
|
||||
|
||||
1/ AABBCCDD.conf (netbooting with regular DHCP)
|
||||
where AABBCCDD is the hexadecimal representation
|
||||
of the IP address assigned during the DHCP phase.
|
||||
|
||||
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.
|
||||
|
||||
3/ elilo.conf
|
||||
|
||||
Unless explicitly specified on the command line, elilo looks for its config file
|
||||
in the filesystem and directory it was loaded from. For instance, if elilo.efi
|
||||
is invoked as:
|
||||
|
||||
fs0:\> \efi\debian\elilo.efi
|
||||
|
||||
Then elilo will look for its configuration file in fs0:\efi\debian and not
|
||||
in the root directory of fs0:. The prefix fs0:\efi\debian will be used for
|
||||
all other files that elilo needs to download when their paths are specified
|
||||
as being relative.
|
||||
|
||||
IMPORTANT:
|
||||
This rule also applies when a specific config file is passed via the -C
|
||||
option. For example:
|
||||
|
||||
fs0:\> \efi\debian\elilo.efi -C elilo.conf
|
||||
|
||||
This will look for elilo.conf in fs0:\efi\debian and not in fs0:\.
|
||||
To get to the elilo.conf in fs0:\, you need to specify the absolute
|
||||
path:
|
||||
|
||||
fs0:\> \efi\debian\elilo.efi -C \elilo.conf
|
||||
|
||||
|
||||
The configuration file is an ASCII file and not a UNICODE file.
|
||||
|
||||
The config file contains additional options to change the behavior of the loader.
|
||||
If the same option is specified in the config file AND on the command line, the
|
||||
latter takes precedence. Not all options available in the config file have an
|
||||
equivalent on command line.
|
||||
|
||||
When elilo is invoked with the -h option, it prints the list of support command line
|
||||
options but also the list of config file options. For each option it also prints
|
||||
the type of data expected.
|
||||
|
||||
The config file options are divided in 2 groups:
|
||||
|
||||
|
||||
- image options which are specific to a particular kernel image. Each kernel image
|
||||
must be identified with a logical name called a label.
|
||||
|
||||
- global options which affect the behavior of ELILO and apply to all images.
|
||||
|
||||
The ELILO config file follows the LILO/x86 syntax. First come the global
|
||||
options, then the list of images and options for each of them, if
|
||||
necessary. At least one image MUST be defined and it is possible to have
|
||||
an empty list of global options.
|
||||
|
||||
Options have types. Three types are defined:
|
||||
- boolean: set or not set
|
||||
- string : a string of characters which can be quoted if necessary
|
||||
- number (in decimal)
|
||||
- filename: a string interpreted as a file name
|
||||
|
||||
|
||||
The config file supports the following options:
|
||||
|
||||
Global Options:
|
||||
---------------
|
||||
default=value Name the default image to boot. If not defined ELILO
|
||||
will boot the first defined image.

|
||||
IV/ Booting from the local system
|
||||
-----------------------------
|
||||
|
||||
The elilo.efi binary must be in an EFI system partition (FAT32). The config
|
||||
file, kernel image, and optional initrd ramdisk can be on the same partition
|
||||
or even another EFI partition. In the following discussion we assume that all
|
||||
files are on the same EFI partition which is recognized by the EFI shell (nshell)
|
||||
as fs0. The kernel and initrd can be copied from the any linux filesystems to the
|
||||
EFI partition using either the mtools (mcopy) or by mounting the EFI partition as
|
||||
a vfat partition. However you do not really need this because most linux
|
||||
distributions install both files in the EFI partition and mount this partition in /boot/efi.
|
||||
|
||||
To boot a kernel, simply power cycle the machine. Once you get to the EFI
|
||||
shell prompt, change to the filesystem that maps to the partition where elilo is.
|
||||
|
||||
Shell> fs0:
|
||||
fs0:\>
|
||||
|
||||
You might need to make sure that the Shell Path is set such that it will load
|
||||
ELILO from fs0:. You can verify this by typing:
|
||||
fs0:\> set
|
||||
path : fs0:\
|
||||
|
||||
At this point you can invoke ELILO:
|
||||
|
||||
fs0:\> elilo
|
||||
|
||||
If there is no config file, then it will:
|
||||
- pick up the kernel image named vmlinux if it exists, otherwise it will abort.
|
||||
- pass no argument to the kernel.
|
||||
|
||||
You can specify the kernel image and its options on the command line.
|
||||
For instance you can do:
|
||||
|
||||
fs0:\> elilo vmlinux root=/dev/sda5
|
||||
|
||||
You can specify as many parameters as you want. The syntax follows the kernel
|
||||
rule, i.e., list of value pairs (or even single values) separated by space.
|
||||
A more complicated example would be:
|
||||
|
||||
fs0:\> elilo -i initrd-2.4.9 vmlinuz-2.4.9 root=/dev/sda2 console=tty0 console="ttyS0,115200n8"
|
||||
|
||||
In this example, notice the double quotes. They are required because the comma is a control
|
||||
character for nshell.
|
||||
|
||||
In the case a config file is found, then elilo will behave according to
|
||||
the options in that file. However if elilo is invoked with command line options, they
|
||||
will be combined or they will override (if conflicting) what is defined in the config file.
|
||||
|
||||
As of version 3.3, elilo is fully compliant with the EFI specification (1.10) with regards
|
||||
to where the bootloader (elilo.efi) must be located in the EFI system partition. In
|
||||
section 11.2.1.3 of the EFI1.10 specification, it is said that in order to avoid conflicts
|
||||
between various loaders for various OSes or distributions of the same OS, every vendor MUST
|
||||
use a dedicated directory: \EFI\vendor\. The bootloader must be placed in this directory.
|
||||
This has always been possible as this is a matter of creating the directory and copying
|
||||
the elilo.efi file in it. However up until version 3.3, elilo would look for its config file
|
||||
and kernel/initrd in the root (/) of the partition it was loaded from. As of version 3.3,
|
||||
elilo will now ONLY look for its configuration file FROM THE DIRECTORY IT WAS LOADED FROM.
|
||||
The same applies to the kernel and initrd files unless absolute paths are specified. Let us
|
||||
look at a simple example:
|
||||
|
||||
- suppose elilo.efi is in \EFI\DIST if fs0: (for the EFI Shell)
|
||||
|
||||
- if you invoke elilo as follows:
|
||||
|
||||
fs0:\> \efi\dist\elilo -v -p
|
||||
default file path: \efi\dist\
|
||||
config file : \efi\dist\elilo.conf
|
||||
ELILO boot:
|
||||
|
||||
|
||||
Note that this is the same if you invoke elilo directly from \efi or \efi\dist.
|
||||
|
||||
File references in the configuration file are treated as relative to the directory
|
||||
elilo was loaded from except if they use an absolute path.
|
||||
|
||||
As of version 3.4 a similar rule applies to the network boot sequence, see netbooting.txt
|
||||
for details.
|
||||
|
||||
V/ Interactive mode
|
||||
----------------
|
||||
|
||||
Elilo can be forced into interactive mode using the "prompt" option in the config
|
||||
file or with the -p option. In this mode, the user can select a kernel to load.
|
||||
|
||||
The interface depends on the chooser, it may be a simple command line prompt as provided
|
||||
by the simple chooser or a more sophisticated screen with scroll menus as provided by
|
||||
textmenu. Most choosers depends on the elilo config file to get the information they
|
||||
display. The simple chooser can operated without the elilo config file. However it
|
||||
is always better to have this file, to create handy logical names for each possible
|
||||
boot choices. The logical names are specified with the "label" option in the config
|
||||
file. They represent a specific kernel "image" and its specific options.
|
||||
|
||||
In elilo, the user can select a particular kernel image using the corresponding label
|
||||
name. A simple example is as follows:
|
||||
|
||||
If we suppose that the following is defined in elilo.conf:
|
||||
|
||||
image=vmlinuz-2.4.9
|
||||
label=linux-up
|
||||
initrd=initrd-2.4.9
|
||||
root=/dev/sda2
|
||||
append="console=tty0 console=ttyS0,115200n8"
|
||||
|
||||
then the user can specify linux-up at the prompt and elilo will load the
|
||||
vmlinuz-2.4.9 kernel file and the initrd-2.4.9 ramdisk and will pass
|
||||
|
||||
"root=/dev/sda2 console=tty0 console=ttyS0,115200n8"
|
||||
|
||||
as command line arguments to the kernel.
|
||||
|
||||
This behavior is identical to Lilo/x86. However, elilo further allows the user
|
||||
to specify actual kernel files names as well, i.e., kernels that are not defined
|
||||
in the configuration file. If we reuse the above example and the simple chooser,
|
||||
the user can type:
|
||||
|
||||
ELILO boot: vmlinux-2.4.18 root=/dev/sda2
|
||||
|
||||
and elilo will boot the vmlinuz-2.4.18 kernel if it exists.
|
||||
|
||||
VI/ The alternate kernel image
|
||||
--------------------------
|
||||
|
||||
Oftentimes when debugging kernels you want to reboot the machine once with
|
||||
your test kernel and, if something goes wrong, you want to fall back to a more
|
||||
stable kernel. In addition you want to be able to do this from a remote machine.
|
||||
Many things can go wrong when doing kernel debugging. It could be that you don't
|
||||
even reach user-mode. In this case however, you still want to fall back to
|
||||
a stable kernel. The feature you'd like from a boot loader is 'boot once and
|
||||
then fall back to safe kernel'.
|
||||
|
||||
Elilo offers this feature and it's called 'alternate kernel image'.
|
||||
You can configure elilo to load a kernel only once and then whatever
|
||||
happens the next reboot falls back to a different kernel hopefully more stable.
|
||||
|
||||
To do this, elilo relies on an EFI variable called 'EliloAlt' with a NULL GUID.
|
||||
The content of this variable is a UNICODE string containing the kernel file name
|
||||
and its command line options.
|
||||
|
||||
When the -a option is specified on the command line or if the "checkalt" option
|
||||
is present in the config file, elilo will check for the presence of this variable.
|
||||
If found and the content is a valid UNICODE string, elilo will use it as the kernel
|
||||
to boot. There is no verification made on the validity of the kernel name or options.
|
||||
Then the variable is deleted. If the variable is rejected because it does not look
|
||||
sane, it is also deleted.
|
||||
|
||||
The variable can be set from a running Linux system using the /proc/efi/vars
|
||||
interface. In the tools directory of this package, there is a Linux tool called
|
||||
elilovar which can be used to create, modify, print, and delete the EliloAlt
|
||||
variable. Refer to eliloalt.txt for more information on this tool.
|
||||
|
||||
VII/ Auto booting the machine
|
||||
-----------------------
|
||||
|
||||
Once you're satisfied with your machine setup, it is good to install an
|
||||
auto boot procedure. You have two options to do this:
|
||||
- from the EFI boot manager menu
|
||||
- from the EFI shell
|
||||
|
||||
The first option is preferred and is used by most Linux distributions.
|
||||
Elilo can be invoked directly from the boot manager. You need to get into
|
||||
the 'boot maintenance' menu and use load file a file. This can be tedious
|
||||
so instead it is recommended that you use a Linux tool called efibootmgr
|
||||
which is also shipped in most distributions. With this tool, you can
|
||||
create your own boot option and change the boot order.
|
||||
|
||||
|
||||
|
||||
The second approach use the EFI shell and a shell script with a special name: 'startup.nsh'.
|
||||
|
||||
When the system boots, it looks for EFI partitions and if it finds
|
||||
a 'startup.nsh' file in ANY of these it will jumpstart execution from it.
|
||||
|
||||
So the typical way of auto booting your Linux/ia64 system is to simply create
|
||||
such a file with the following content:
|
||||
|
||||
# cat /boot/startup.nsh
|
||||
elilo vmlinuz root=/dev/sda2
|
||||
|
||||
Of course, this can be simplified if there is a configuration file.
|
||||
|
||||
|
||||
VII/ Netbooting
|
||||
----------
|
||||
|
||||
Please refer to netbooting.txt for a complete description of how to boot
|
||||
from the network.
|
||||
|
||||
|
||||
XII/ Booting on EFI/ia32 platforms
|
||||
-----------------------------
|
||||
|
||||
Until PC comes with the EFI firmware built in, you need to boot from a
|
||||
floppy that has the EFI firmware on it. Such floppy can be
|
||||
constructed from the EFI sample implementation and toolkit that is
|
||||
available from the Intel Developer Web site at:
|
||||
|
||||
http://developer.intel.com/technology/efi/
|
||||
|
||||
To use elilo on IA-32, you can put it on a floppy and
|
||||
on a FAT32 partition (msdos partition). You can also
|
||||
netbooting if you network adapter has support for UNDI/PXE.
|
||||
|
||||
Elilo/ia32 is capable of booting unmodified 2.2.x. and 2.4.x kernels
|
||||
as they are shipped by distributors today (such as Redhat7.2). You don't need
|
||||
to recompile the kernel with special options. Elilo ONLY takes compressed kernel
|
||||
image which are typically obtained via a 'make bzImage'. Plain elf/32 kernel can't
|
||||
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.

|

===================================
|
||||
|
||||
QUICK CHANGE SUMMARY
|
||||
====================
|
||||
* Fixes for newly emerging x86_64 UEFI-2 boxes where long standing old
|
||||
assumptions are borked.
|
||||
* Uptake of SUSE and community patches
|
||||
- add sysfs support for efi vars (formerly /proc/efi/vars)
|
||||
- fix strncpy overflow
|
||||
- fix bzimage alloc
|
||||
- cleanups
|
||||
- support longer command line
|
||||
- yet some more mac fixes
|
||||
- align elilo with latest kernel boot protocol format.
|
||||
- new memory management strategy for initrd and kernel image loading.
|
||||
* add text-mode command line option, force text-mode (bypass graphics probes).
|
||||
* replace error output on GOP handle failed, downgraded to normal
|
||||
print status with more informative output.
|
||||
* Fix ia32 build issue with new gcc due to stack protector enforcement.
|
||||
* Adds native x86x crossbuild functionality
|
||||
build 32bit or 64bit versions from either environment via
|
||||
make ARCH=ia32|x86_64 (the ARCH IS case sensitive).
|
||||
make by itself will default to the native host arch.
|
||||
* Add console reset call during initialization. thanks A. Steinmetz
|
||||
* simplify output of no GOP warning text so it no longer looks like an error.
|
||||
* MAJOR: Fixed Fault crash when EFI memory map changes from under elilo.
|
||||
(from an outside interrupt in this case). When the EFI Memory map
|
||||
changes after elilo has already built boot params to pass to the
|
||||
kernel the EFI call to ExitBootSvcs just prior to boot will fail
|
||||
because elilo has the old map key. This is valid EFI behavior, elilo
|
||||
retries to pick up the new memory map and key but had already freed
|
||||
the start params portion of boot params resulting in a NULL DEREF
|
||||
crash reset once it hands the now bogus boot params to the kernel on
|
||||
the 2nd successful call to exit efi and boot.
|
||||
Thanks to Jerry Hoemann @ HP for reporting this bug.
|
||||
* minor bugfix, fixed -m option broken. thanks Allan-lsk.

||||

||||
BUILD NOTES
|
||||
====================
|
||||
You will need the following toolchain to build elilo-3.14 from source
|
||||
the elilo build environment is optimized for Debian and Debian based distros.
|
||||
elilo-3.14 was built in the Debian Lenny (Ubuntu 10.04) build environment.
|
||||
elilo-3.16 was built in the squeeze+(ubuntu 11.x) build environments except
|
||||
for itanium which is unchanged to best support legacy enterprise configs.
|
||||
Toolchain versions for this release were:
|
||||
x86x(32 &64)
|
||||
* gnu-efi --> 3.0i-2ubuntu1
|
||||
* gcc ------> 4.4.3-1ubuntu1
|
||||
* binutils -> 2.20.1-3ubuntu7
|
||||
x86x(32 & 64bit versions)
|
||||
* gnu-efi --> 3.0i-3
|
||||
* gcc ------> 4:4.4.4-1ubuntu2
|
||||
* binutils -> 2.20.51.20100908-0ubuntu2
|
||||
ia64
|
||||
* gnu-efi --> 3.0e-2
|
||||
* gcc ------> 4.3.2-2
|
||||
* binutils -> 2.18.1~cvs20080103-7
|
||||
|
||||
* if you use a debian based (lenny)build environment you will have no problems
|
||||
* if you use a debian based build environment you will have no problems
|
||||
and setting it up is simple. you will be able to build elilo in 3 steps:
|
||||
1. apt-get install gnu-efi, gcc, binutils
|
||||
2. apt-get source elilo (or download elilo-3.14.tar.gz from SourceForge.)
|
||||
3. extract source tarball and cd ./elilo-3.14 and type $> make
|
||||
2. apt-get source elilo (or download elilo-3.16 source from SourceForge.)
|
||||
3. extract source tarball and cd to ./$your-elilo-source and type $> make
|
||||
|
||||
|
||||
** If you use the upstream toolchain tarballs(i.e. pre distro) you will need
