@node Changes from GRUB Legacy
@section Differences from previous versions
GRUB 2 is a rewrite of GRUB (@pxref{History}), although it shares many
characteristics with the previous version, now known as GRUB Legacy. Users
of GRUB Legacy may need some guidance to find their way around this new
version.
@itemize @bullet
@item
The configuration file has a new name (@file{grub.cfg} rather than
@file{menu.lst} or @file{grub.conf}), new syntax (@pxref{Configuration}) and
many new commands (@pxref{Commands}). Configuration cannot be copied over
directly, although most GRUB Legacy users should not find the syntax too
surprising.
@item
@file{grub.cfg} is typically automatically generated by
@command{grub-mkconfig} (@pxref{Simple configuration}). This makes it
easier to handle versioned kernel upgrades.
@item
Partition numbers in GRUB device names now start at 1, not 0 (@pxref{Naming
convention}).
@item
The configuration file is now written in something closer to a full
scripting language: variables, conditionals, and loops are available.
@item
A small amount of persistent storage is available across reboots, using the
@command{save_env} and @command{load_env} commands in GRUB and the
@command{grub-editenv} utility.
@item
GRUB 2 has more reliable ways to find its own files and those of target
kernels on multiple-disk systems, and has commands (@pxref{search}) to find
devices using file system labels or Universally Unique Identifiers (UUIDs).
@item
GRUB 2 is available for several other types of system in addition to the PC
BIOS systems supported by GRUB Legacy: PC EFI, PC coreboot, PowerPC, SPARC,
and MIPS Lemote Yeeloong are all supported.
@item
Many more file systems are supported, including but not limited to ext4,
HFS+, and NTFS.
@item
GRUB 2 can read files directly from LVM and RAID devices.
@item
A graphical terminal and a graphical menu system are available.
@item
GRUB 2's interface can be translated, including menu entry names.
@item
The image files (@pxref{Images}) that make up GRUB have been reorganised;
Stage 1, Stage 1.5, and Stage 2 are no more.
@item
GRUB 2 puts many facilities in dynamically loaded modules, allowing the core
image to be smaller, and allowing the core image to be built in more
flexible ways.

@node Device map
@section The map between BIOS drives and OS devices
The @command{grub-mkdevicemap} program can be used to create the @dfn{device
map file}. It is often run automatically by tools such as
@command{grub-install} if the device map file does not already exist. The
file name @file{/boot/grub/device.map} is preferred.
If the device map file exists, the GRUB utilities (@command{grub-probe},
@command{grub-setup}, etc.) read it to map BIOS drives to OS devices. This
file consists of lines like this:
@example
@var{device} @var{file}
@end example
@var{device} is a drive specified in the GRUB syntax (@pxref{Device
syntax}), and @var{file} is an OS file, which is normally a device file.
Historically, the device map file was used because GRUB device names had to
be used in the configuration file, and they were derived from BIOS drive
numbers. The map between BIOS drives and OS devices cannot always be
guessed correctly: for example, GRUB will get the order wrong if you
exchange the boot sequence between IDE and SCSI in your BIOS.
Unfortunately, even OS device names are not always stable. Modern versions
of the Linux kernel may probe drives in a different order from boot to boot,
and the prefix (@file{/dev/hd*} versus @file{/dev/sd*}) may change depending
on the driver subsystem in use. As a result, the device map file required
frequent editing on some systems.
GRUB avoids this problem nowadays by using UUIDs or file system labels when
generating @file{grub.cfg}, and we advise that you do the same for any
custom menu entries you write. If the device map file does not exist, then
the GRUB utilities will assume a temporary device map on the fly. This is
often good enough, particularly in the common case of single-disk systems.
However, the device map file is not entirely obsolete yet, and there are
still some situations that require it to exist. If necessary, you may edit
the file if @command{grub-mkdevicemap} makes a mistake. You can put any
comments in the file if needed, as the GRUB utilities assume that a line is
just a comment if the first character is @samp{#}.

@section Writing full configuration files directly
@node Embedded configuration
@section Embedding a configuration file into GRUB
GRUB supports embedding a configuration file directly into the core image,
so that it is loaded before entering normal mode. This is useful, for
example, when it is not straightforward to find the real configuration file,
or when you need to debug problems with loading that file.
@command{grub-install} uses this feature when it is not using BIOS disk
functions or when installing to a different disk from the one containing
@file{/boot/grub}, in which case it needs to use the @command{search}
command (@pxref{search}) to find @file{/boot/grub}.
To embed a configuration file, use the @option{-c} option to
@command{grub-mkimage}. The file is copied into the core image, so it may
reside anywhere on the file system, and may be removed after running
@command{grub-mkimage}.
After the embedded configuration file (if any) is executed, GRUB will load
the @samp{normal} module, which will then read the real configuration file
from @file{$prefix/grub.cfg}. By this point, the @code{root} variable will
also have been set to the root device name. For example, @code{prefix}
might be set to @samp{(hd0,1)/boot/grub}, and @code{root} might be set to
@samp{hd0,1}. Thus, in most cases, the embedded configuration file only
needs to set the @code{prefix} and @code{root} variables, and then drop
through to GRUB's normal processing. A typical example of this might look
like this:
@example
@group
search.fs_uuid 01234567-89ab-cdef-0123-456789abcdef root
set prefix=($root)/boot/grub
@end group
@end example
(The @samp{search_fs_uuid} module must be included in the core image for this
example to work.)
In more complex cases, it may be useful to read other configuration files
directly from the embedded configuration file. This allows such things as
reading files not called @file{grub.cfg}, or reading files from a directory
other than that where GRUB's loadable modules are installed. To do this,
include the @samp{configfile} and @samp{normal} modules in the core image,
and embed a configuration file that uses the @command{configfile} command to
load another file. The following example of this also requires the
@command{echo}, @command{search_label}, and @command{test} modules to be
included in the core image:
@example
@group
search.fs_label grub root
if [ -e /boot/grub/example/test1.cfg ]; then
set prefix=($root)/boot/grub
configfile /boot/grub/example/test1.cfg
else
if [ -e /boot/grub/example/test2.cfg ]; then
set prefix=($root)/boot/grub
configfile /boot/grub/example/test2.cfg
else
echo "Could not find an example configuration file!"
fi
fi
@end group
@end example
The embedded configuration file may not contain menu entries directly, but
may only read them from elsewhere using @command{configfile}.

@node Images
@chapter GRUB image files
@c FIXME: parts of this section are specific to PC BIOS right now.
GRUB consists of several images: a variety of bootstrap images for starting
GRUB in various ways, a kernel image, and a set of modules which are
combined with the kernel image to form a core image. Here is a short
overview of them.
@table @file
@item boot.img
On PC BIOS systems, this image is the first part of GRUB to start. It is
written to a master boot record (MBR) or to the boot sector of a partition.
Because a PC boot sector is 512 bytes, the size of this image is exactly 512
bytes.
The sole function of @file{boot.img} is to read the first sector of the core
image from a local disk and jump to it. Because of the size restriction,
@file{boot.img} cannot understand any file system structure, so
@command{grub-setup} hardcodes the location of the first sector of the core
image into @file{boot.img} when installing GRUB.
@item diskboot.img
This image is used as the first sector of the core image when booting from a
hard disk. It reads the rest of the core image into memory and starts the
kernel. Since file system handling is not yet available, it encodes the
location of the core image using a block list format.
@item cdboot.img
This image is used as the first sector of the core image when booting from a
CD-ROM drive. It performs a similar function to @file{diskboot.img}.
@item pxeboot.img
This image is used as the start of the core image when booting from the
network using PXE. @xref{Network}.
@item lnxboot.img
This image may be placed at the start of the core image in order to make
GRUB look enough like a Linux kernel that it can be booted by LILO using an
@samp{image=} section.
@item kernel.img
This image contains GRUB's basic run-time facilities: frameworks for device
and file handling, environment variables, the rescue mode command-line
parser, and so on. It is rarely used directly, but is built into all core
images.
@item core.img
This is the core image of GRUB. It is built dynamically from the kernel
image and an arbitrary list of modules by the @command{grub-mkimage}
program. Usually, it contains enough modules to access @file{/boot/grub},
and loads everything else (including menu handling, the ability to load
target operating systems, and so on) from the file system at run-time. The
modular design allows the core image to be kept small, since the areas of
disk where it must be installed are often as small as 32KB.
On PC systems using the traditional MBR partition table format, the core
image is usually installed in the "MBR gap" between the master boot record
and the first partition, or sometimes it is installed in a file system and
read directly from that. The latter is not recommended because GRUB needs
to encode the location of all the core image sectors in @file{diskboot.img},
and if the file system ever moves the core image around (as it is entitled
to do) then GRUB must be reinstalled; it also means that GRUB will not be
able to reliably find the core image if it resides on a different disk than
the one to which @file{boot.img} was installed.
On PC systems using the more recent GUID Partition Table (GPT) format, the
core image should be installed to a BIOS Boot Partition. This may be
created by GNU Parted using a command such as the following:
@example
# @kbd{parted /dev/@var{disk} set @var{partition-number} bios_grub on}
@end example
@strong{Caution:} Be very careful which partition you select! When GRUB
finds a BIOS Boot Partition during installation, it will automatically
overwrite part of it. Make sure that the partition does not contain any
other data.
@item *.mod
Everything else in GRUB resides in dynamically loadable modules. These are
often loaded automatically, or built into the core image if they are
essential, but may also be loaded manually using the @command{insmod}
command (@pxref{insmod}).
@end table
@heading For GRUB Legacy users
GRUB 2 has a different design from GRUB Legacy, and so correspondences with
the images it used cannot be exact. Nevertheless, GRUB Legacy users often
ask questions in the terms they are familiar with, and so here is a brief
guide to how GRUB 2's images relate to that.
@table @file
@item stage1
Stage 1 from GRUB Legacy was very similar to @file{boot.img} in GRUB 2, and
they serve the same function.
@item *_stage1_5
In GRUB Legacy, Stage 1.5's function was to include enough filesystem code
to allow the much larger Stage 2 to be read from an ordinary filesystem. In
this respect, its function was similar to @file{core.img} in GRUB 2.
However, @file{core.img} is much more capable than Stage 1.5 was; since it
offers a rescue shell, it is sometimes possible to recover manually in the
event that it is unable to load any other modules, for example if partition
numbers have changed. @file{core.img} is built in a more flexible way,
allowing GRUB 2 to support reading modules from advanced disk types such as
LVM and RAID.
GRUB Legacy could run with only Stage 1 and Stage 2 in some limited
configurations, while GRUB 2 requires @file{core.img} and cannot work
without it.
@item stage2
GRUB 2 has no single Stage 2 image. Instead, it loads modules from
@file{/boot/grub} at run-time.
@item stage2_eltorito
In GRUB 2, images for booting from CD-ROM drives are now constructed using
@file{cdboot.img} and @file{core.img}, making sure that the core image
contains the @samp{iso9660} module. It is usually best to use the
@command{grub-mkrescue} program for this.
@item nbgrub
There is as yet no equivalent for @file{nbgrub} in GRUB 2; it was used by
Etherboot and some other network boot loaders.
@item pxegrub
In GRUB 2, images for PXE network booting are now constructed using
@file{pxeboot.img} and @file{core.img}, making sure that the core image
contains the @samp{pxe} and @samp{pxecmd} modules. @xref{Network}.

@subsection badram
@deffn Command badram addr,mask[,addr,mask...]
Filter out bad RAM.
@end deffn
This command notifies the memory manager that specified regions of
RAM ought to be filtered out (usually, because they're damaged). This
remains in effect after a payload kernel has been loaded by GRUB, as
long as the loaded kernel obtains its memory map from GRUB. Kernels that
support this include Linux, GNU Mach, the kernel of FreeBSD and Multiboot
kernels in general.
Syntax is the same as provided by the @uref{http://www.memtest.org/,
Memtest86+ utility}: a list of address/mask pairs. Given a page-aligned
address and a base address / mask pair, if all the bits of the page-aligned
address that are enabled by the mask match with the base address, it means
this page is to be filtered. This syntax makes it easy to represent patterns
that are often result of memory damage, due to physical distribution of memory
cells.
