+@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

+
+The embedded configuration file may not contain menu entries directly, but
+may only read them from elsewhere using @command{configfile}.

+@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}.

+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.
