It is responsible for loading and transferring -control to an operating system "kernel" software (such as Linux or GNU -Mach). The kernel, in turn, initializes the rest of the operating -system (e.g. a GNU system). - - GNU GRUB is a very powerful boot loader, which can load a wide -variety of free operating systems, as well as proprietary operating -systems with chain-loading(1) (*note Overview-Footnote-1::). GRUB is -designed to address the complexity of booting a personal computer; both -the program and this manual are tightly bound to that computer platform, -although porting to other platforms may be addressed in the future. - - One of the important features in GRUB is flexibility; GRUB -understands filesystems and kernel executable formats, so you can load -an arbitrary operating system the way you like, without recording the -physical position of your kernel on the disk. Thus you can load the -kernel just by specifying its file name and the drive and partition -where the kernel resides. - - When booting with GRUB, you can use either a command-line interface -(*note Command-line interface::), or a menu interface (*note Menu -interface::). Using the command-line interface, you type the drive -specification and file name of the kernel manually. In the menu -interface, you just select an OS using the arrow keys. The menu is -based on a configuration file which you prepare beforehand (*note -Configuration::). While in the menu, you can switch to the command-line -mode, and vice-versa. You can even edit menu entries before using them. - - In the following chapters, you will learn how to specify a drive, a -partition, and a file name (*note Naming convention::) to GRUB, how to -install GRUB on your drive (*note Installation::), and how to boot your -OSes (*note Booting::), step by step. - - -File: grub.info, Node: Overview-Footnotes, Up: Overview - - (1) "chain-load" is the mechanism for loading unsupported operating -systems by loading another boot loader. It is typically used for -loading DOS or Windows. - - -File: grub.info, Node: History, Next: Features, Prev: Overview, Up: Introduction - -1.2 History of GRUB -=================== - -GRUB originated in 1995 when Erich Boleyn was trying to boot the GNU -Hurd with the University of Utah's Mach 4 microkernel (now known as GNU -Mach). Erich and Brian Ford designed the Multiboot Specification -(*note Multiboot Specification: (multiboot)Top.), because they were -determined not to add to the large number of mutually-incompatible PC -boot methods. - - Erich then began modifying the FreeBSD boot loader so that it would -understand Multiboot. He soon realized that it would be a lot easier to -write his own boot loader from scratch than to keep working on the -FreeBSD boot loader, and so GRUB was born. - - Erich added many features to GRUB, but other priorities prevented him -from keeping up with the demands of its quickly-expanding user base. In -1999, Gordon Matzigkeit and Yoshinori K. Okuji adopted GRUB as an -official GNU package, and opened its development by making the latest -sources available via anonymous CVS. *Note Obtaining and Building -GRUB::, for more information. - - -File: grub.info, Node: Features, Next: Role of a boot loader, Prev: History, Up: Introduction - -1.3 GRUB features -================= - -The primary requirement for GRUB is that it be compliant with the -"Multiboot Specification", which is described in *note Multiboot -Specification: (multiboot)Top. - - The other goals, listed in approximate order of importance, are: - - * Basic functions must be straightforward for end-users. - - * Rich functionality to support kernel experts and designers. - - * Backward compatibility for booting FreeBSD, NetBSD, OpenBSD, and - Linux. Proprietary kernels (such as DOS, Windows NT, and OS/2) are - supported via a chain-loading function. - - Except for specific compatibility modes (chain-loading and the Linux -"piggyback" format), all kernels will be started in much the same state -as in the Multiboot Specification. Only kernels loaded at 1 megabyte or -above are presently supported. Any attempt to load below that boundary -will simply result in immediate failure and an error message reporting -the problem. - - In addition to the requirements above, GRUB has the following -features (note that the Multiboot Specification doesn't require all the -features that GRUB supports): - -Recognize multiple executable formats - Support many of the "a.out" variants plus "ELF". Symbol tables are - also loaded. - -Support non-Multiboot kernels - Support many of the various free 32-bit kernels that lack Multiboot - compliance (primarily FreeBSD, NetBSD, OpenBSD, and Linux). - Chain-loading of other boot loaders is also supported. - -Load multiples modules - Fully support the Multiboot feature of loading multiple modules. - -Load a configuration file - Support a human-readable text configuration file with preset boot - commands. You can also load another configuration file dynamically - and embed a preset configuration file in a GRUB image file. The - list of commands (*note Commands::) are a superset of those - supported on the command-line. An example configuration file is - provided in *note Configuration::. - -Provide a menu interface - A menu interface listing preset boot commands, with a programmable - timeout, is available. There is no fixed limit on the number of - boot entries, and the current implementation has space for several - hundred. - -Have a flexible command-line interface - A fairly flexible command-line interface, accessible from the menu, - is available to edit any preset commands, or write a new boot - command set from scratch. If no configuration file is present, - GRUB drops to the command-line. - - The list of commands (*note Commands::) are a subset of those - supported for configuration files. Editing commands closely - resembles the Bash command-line (*note Bash: (features)Command - Line Editing.), with <TAB>-completion of commands, devices, - partitions, and files in a directory depending on context. - -Support multiple filesystem types - Support multiple filesystem types transparently, plus a useful - explicit blocklist notation. The currently supported filesystem - types are "BSD FFS", "DOS FAT16 and FAT32", "Minix fs", "Linux - ext2fs", "ReiserFS", "JFS", "XFS", and "VSTa fs". *Note - Filesystem::, for more information. - -Support automatic decompression - Can decompress files which were compressed by `gzip'. This - function is both automatic and transparent to the user (i.e. all - functions operate upon the uncompressed contents of the specified - files). This greatly reduces a file size and loading time, a - particularly great benefit for floppies.(1) (*note - Features-Footnote-1::) - - It is conceivable that some kernel modules should be loaded in a - compressed state, so a different module-loading command can be - specified to avoid uncompressing the modules. - -Access data on any installed device - Support reading data from any or all floppies or hard disk(s) - recognized by the BIOS, independent of the setting of the root - device. - -Be independent of drive geometry translations - Unlike many other boot loaders, GRUB makes the particular drive - translation irrelevant. A drive installed and running with one - translation may be converted to another translation without any - adverse effects or changes in GRUB's configuration. - -Detect all installed RAM - GRUB can generally find all the installed RAM on a PC-compatible - machine. It uses an advanced BIOS query technique for finding all - memory regions. As described on the Multiboot Specification (*note - Multiboot Specification: (multiboot)Top.), not all kernels make - use of this information, but GRUB provides it for those who do. - -Support Logical Block Address mode - In traditional disk calls (called "CHS mode"), there is a geometry - translation problem, that is, the BIOS cannot access over 1024 - cylinders, so the accessible space is limited to at least 508 MB - and to at most 8GB. GRUB can't universally solve this problem, as - there is no standard interface used in all machines. However, - several newer machines have the new interface, Logical Block - Address ("LBA") mode. GRUB automatically detects if LBA mode is - available and uses it if available. In LBA mode, GRUB can access - the entire disk. - -Support network booting - GRUB is basically a disk-based boot loader but also has network - support. You can load OS images from a network by using the "TFTP" - protocol. - -Support remote terminals - To support computers with no console, GRUB provides remote terminal - support, so that you can control GRUB from a remote host. Only - serial terminal support is implemented at the moment. - - -File: grub.info, Node: Features-Footnotes, Up: Features - - (1) There are a few pathological cases where loading a very badly -organized ELF kernel might take longer, but in practice this never -happen. - - -File: grub.info, Node: Role of a boot loader, Prev: Features, Up: Introduction - -1.4 The role of a boot loader -============================= - -The following is a quotation from Gordon Matzigkeit, a GRUB fanatic: - - Some people like to acknowledge both the operating system and - kernel when they talk about their computers, so they might say - they use "GNU/Linux" or "GNU/Hurd". Other people seem to think - that the kernel is the most important part of the system, so they - like to call their GNU operating systems "Linux systems." - - I, personally, believe that this is a grave injustice, because the - _boot loader_ is the most important software of all. I used to - refer to the above systems as either "LILO"(1) (*note Role of a - boot loader-Footnote-1::) or "GRUB" systems. - - Unfortunately, nobody ever understood what I was talking about; - now I just use the word "GNU" as a pseudonym for GRUB. - - So, if you ever hear people talking about their alleged "GNU" - systems, remember that they are actually paying homage to the best - boot loader around... GRUB! - - We, the GRUB maintainers, do not (usually) encourage Gordon's level -of fanaticism, but it helps to remember that boot loaders deserve -recognition. We hope that you enjoy using GNU GRUB as much as we did -writing it. - - -File: grub.info, Node: Role of a boot loader-Footnotes, Up: Role of a boot loader - - (1) The LInux LOader, a boot loader that everybody uses, but nobody -likes. - - -File: grub.info, Node: Naming convention, Next: Installation, Prev: Introduction, Up: Top - -2 Naming convention -******************* - -The device syntax used in GRUB is a wee bit different from what you may -have seen before in your operating system(s), and you need to know it so -that you can specify a drive/partition. - - Look at the following examples and explanations: - - (fd0) - - First of all, GRUB requires that the device name be enclosed with -`(' and `)'. The `fd' part means that it is a floppy disk. The number -`0' is the drive number, which is counted from _zero_. This expression -means that GRUB will use the whole floppy disk. - - (hd0,2) - - Here, `hd' means it is a hard disk drive. The first integer `0' -indicates the drive number, that is, the first hard disk, while the -second integer, `1', indicates the partition number (or the PC slice -number in the BSD terminology). The partition numbers are counted from -_one_, not from zero (as was the case in previous versions of GRUB). -This expression means the second partition of the first hard disk -drive. In this case, GRUB uses one partition of the disk, instead of -the whole disk. - - (hd0,5) - - This specifies the first "extended partition" of the first hard disk -drive. Note that the partition numbers for extended partitions are -counted from `5', regardless of the actual number of primary partitions -on your hard disk. - - (hd1,a) - - This means the BSD `a' partition of the second hard disk. If you -need to specify which PC slice number should be used, use something -like this: `(hd1,1,a)'. If the PC slice number is omitted, GRUB -searches for the first PC slice which has a BSD `a' partition. - - Of course, to actually access the disks or partitions with GRUB, you -need to use the device specification in a command, like `root (fd0)' or -`unhide (hd0,3)'. To help you find out which number specifies a -partition you want, the GRUB command-line (*note Command-line -interface::) options have argument completion. This means that, for -example, you only need to type - - root ( - - followed by a <TAB>, and GRUB will display the list of drives, -partitions, or file names. So it should be quite easy to determine the -name of your target partition, even with minimal knowledge of the -syntax. - - Note that GRUB does _not_ distinguish IDE from SCSI - it simply -counts the drive numbers from zero, regardless of their type. Normally, -any IDE drive number is less than any SCSI drive number, although that -is not true if you change the boot sequence by swapping IDE and SCSI -drives in your BIOS. - - Now the question is, how to specify a file? Again, consider an -example: - - (hd0,1)/vmlinuz - - This specifies the file named `vmlinuz', found on the first -partition of the first hard disk drive. Note that the argument -completion works with file names, too. - - That was easy, admit it. Now read the next chapter, to find out how -to actually install GRUB on your drive. - - -File: grub.info, Node: Installation, Next: Booting, Prev: Naming convention, Up: Top - -3 Installation -************** - -In order to install GRUB as your boot loader, you need to first install -the GRUB system and utilities under your UNIX-like operating system -(*note Obtaining and Building GRUB::). You can do this either from the -source tarball, or as a package for your OS. - - After you have done that, you need to install the boot loader on a -drive (floppy or hard disk). There are two ways of doing that - either -using the utility `grub-install' (*note Invoking grub-install::) on a -UNIX-like OS, or by running GRUB itself from a floppy. These are quite -similar, however the utility might probe a wrong BIOS drive, so you -should be careful. - - Also, if you install GRUB on a UNIX-like OS, please make sure that -you have an emergency boot disk ready, so that you can rescue your -computer if, by any chance, your hard drive becomes unusable -(unbootable). - - GRUB comes with boot images, which are normally put in the directory -`/usr/lib/grub/i386-pc'. Hereafter, the directory where GRUB images are -initially placed (normally `/usr/lib/grub/i386-pc') will be called the -"image directory", and the directory where the boot loader needs to -find them (usually `/boot/grub') will be called the "boot directory". - -* Menu: - -* Installing GRUB using grub-install:: -* Making a GRUB bootable CD-ROM:: - - -File: grub.info, Node: Installing GRUB using grub-install, Next: Making a GRUB bootable CD-ROM, Up: Installation - -3.1 Installing GRUB using grub-install -====================================== - -*Caution:* This procedure is definitely less safe, because there are -several ways in which your computer can become unbootable. For example, -most operating systems don't tell GRUB how to map BIOS drives to OS -devices correctly--GRUB merely "guesses" the mapping. This will succeed -in most cases, but not always. Therefore, GRUB provides you with a map -file called the "device map", which you must fix if it is wrong. *Note -Device map::, for more details. - - If you still do want to install GRUB under a UNIX-like OS (such as -GNU), invoke the program `grub-install' (*note Invoking grub-install::) -as the superuser ("root"). - - The usage is basically very simple. You only need to specify one -argument to the program, namely, where to install the boot loader. The -argument can be either a device file (like `/dev/hda') or a partition -specified in GRUB's notation. For example, under Linux the following -will install GRUB into the MBR of the first IDE disk: - - # grub-install /dev/hda - - Likewise, under GNU/Hurd, this has the same effect: - - # grub-install /dev/hd0 - - If it is the first BIOS drive, this is the same as well: - - # grub-install '(hd0)' - - Or you can omit the parentheses: - - # grub-install hd0 - - But all the above examples assume that GRUB should use images under -the root directory. If you want GRUB to use images under a directory -other than the root directory, you need to specify the option -`--root-directory'. The typical usage is that you create a GRUB boot -floppy with a filesystem. Here is an example: - - # mke2fs /dev/fd0 - # mount -t ext2 /dev/fd0 /mnt - # grub-install --root-directory=/mnt fd0 - # umount /mnt - - Another example is when you have a separate boot partition which is -mounted at `/boot'. Since GRUB is a boot loader, it doesn't know -anything about mountpoints at all. Thus, you need to run `grub-install' -like this: - - # grub-install --root-directory=/boot /dev/hda - - By the way, as noted above, it is quite difficult to guess BIOS -drives correctly under a UNIX-like OS. Thus, `grub-install' will prompt -you to check if it could really guess the correct mappings, after the -installation. The format is defined in *note Device map::. Please be -quite careful. If the output is wrong, it is unlikely that your -computer will be able to boot with no problem. - - Note that `grub-install' is actually just a shell script and the -real task is done by `grub-mkimage' and `grub-setup'. Therefore, you -may run those commands directly to install GRUB, without using -`grub-install'. Don't do that, however, unless you are very familiar -with the internals of GRUB. Installing a boot loader on a running OS -may be extremely dangerous. - - -File: grub.info, Node: Making a GRUB bootable CD-ROM, Prev: Installing GRUB using grub-install, Up: Installation - -3.2 Making a GRUB bootable CD-ROM -================================= - -GRUB supports the "no emulation mode" in the El Torito specification(1) -(*note Making a GRUB bootable CD-ROM-Footnote-1::). This means that you -can use the whole CD-ROM from GRUB and you don't have to make a floppy -or hard disk image file, which can cause compatibility problems. - - For booting from a CD-ROM, GRUB uses a special Stage 2 called -`stage2_eltorito'. The only GRUB files you need to have in your -bootable CD-ROM are this `stage2_eltorito' and optionally a config file -`grub.cfg'. You don't need to use `stage1' or `stage2', because El -Torito is quite different from the standard boot process. - - Here is an example of procedures to make a bootable CD-ROM image. -First, make a top directory for the bootable image, say, `iso': - - $ mkdir iso - - Make a directory for GRUB: - - $ mkdir -p iso/boot/grub - - Copy the file `stage2_eltorito': - - $ cp /usr/lib/grub/i386-pc/stage2_eltorito iso/boot/grub - - If desired, make the config file `grub.cfg' under `iso/boot/grub' -(*note Configuration::), and copy any files and directories for the -disc to the directory `iso/'. - - Finally, make a ISO9660 image file like this: - - $ mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot \ - -boot-load-size 4 -boot-info-table -o grub.iso iso - - This produces a file named `grub.iso', which then can be burned into -a CD (or a DVD). `mkisofs' has already set up the disc to boot from -the `boot/grub/stage2_eltorito' file, so there is no need to setup GRUB -on the disc. (Note that the `-boot-load-size 4' bit is required for -compatibility with the BIOS on many older machines.) - - You can use the device `(cd)' to access a CD-ROM in your config -file. This is not required; GRUB automatically sets the root device to -`(cd)' when booted from a CD-ROM. It is only necessary to refer to -`(cd)' if you want to access other drives as well. - - -File: grub.info, Node: Making a GRUB bootable CD-ROM-Footnotes, Up: Making a GRUB bootable CD-ROM - - (1) El Torito is a specification for bootable CD using BIOS -functions. - - -File: grub.info, Node: Booting, Next: Configuration, Prev: Installation, Up: Top - -4 Booting -********* - -GRUB can load Multiboot-compliant kernels in a consistent way, but for -some free operating systems you need to use some OS-specific magic. - -* Menu: - -* General boot methods:: How to boot OSes with GRUB generally -* OS-specific notes:: Notes on some operating systems - - -File: grub.info, Node: General boot methods, Next: OS-specific notes, Up: Booting - -4.1 How to boot operating systems -================================= - -GRUB has two distinct boot methods. One of the two is to load an -operating system directly, and the other is to chain-load another boot -loader which then will load an operating system actually. Generally -speaking, the former is more desirable, because you don't need to -install or maintain other boot loaders and GRUB is flexible enough to -load an operating system from an arbitrary disk/partition.

However, their boot loaders have some critical -deficiencies, so it may not work to just chain-load them. To overcome -the problems, GRUB provides you with a helper function. - - If you have installed DOS (or Windows) on a non-first hard disk, you -have to use the disk swapping technique, because that OS cannot boot -from any disks but the first one. The workaround used in GRUB is the -command `drivemap' (*note drivemap::), like this: - - drivemap -s (hd0) (hd1) - - This performs a "virtual" swap between your first and second hard -drive. - - *Caution:* This is effective only if DOS (or Windows) uses BIOS to -access the swapped disks.

It is suitable for use when -upgrading a distribution, and will discover available kernels and -attempt to generate menu entries for them. - - The file `/etc/default/grub' controls the operation of -`grub-mkconfig'. It is sourced by a shell script, and so must be valid -POSIX shell input; normally, it will just be a sequence of `KEY=value' -lines, but if the value contains spaces or other special characters -then it must be quoted. For example: - - GRUB_TERMINAL_INPUT="console serial" - - Valid keys in `/etc/default/grub' are as follows: - -`GRUB_DEFAULT' - The default menu entry. This may be a number, in which case it - identifies the Nth entry in the generated menu counted from zero, - or the full name of a menu entry, or the special string `saved'. - Using the full name may be useful if you want to set a menu entry - as the default even though there may be a variable number of - entries before it. - - If you set this to `saved', then the default menu entry will be - that saved by `GRUB_SAVEDEFAULT', `grub-set-default', or - `grub-reboot'. - - The default is `0'. - -`GRUB_SAVEDEFAULT' - If this option is set to `true', then, when an entry is selected, - save it as a new default entry for use by future runs of GRUB. - This is only useful if `GRUB_DEFAULT=saved'; it is a separate - option because `GRUB_DEFAULT=saved' is useful without this option, - in conjunction with `grub-set-default' or `grub-reboot'. Unset by - default. - -`GRUB_TIMEOUT' - Boot the default entry this many seconds after the menu is - displayed, unless a key is pressed. The default is `5'. Set to - `0' to boot immediately without displaying the menu, or to `-1' to - wait indefinitely. - -`GRUB_HIDDEN_TIMEOUT' - Wait this many seconds for a key to be pressed before displaying - the menu. If no key is pressed during that time, boot - immediately. Unset by default. - -`GRUB_HIDDEN_TIMEOUT_QUIET' - In conjunction with `GRUB_HIDDEN_TIMEOUT', set this to `true' to - suppress the verbose countdown while waiting for a key to be - pressed before displaying the menu. Unset by default. - -`GRUB_DEFAULT_BUTTON' -`GRUB_TIMEOUT_BUTTON' -`GRUB_HIDDEN_TIMEOUT_BUTTON' -`GRUB_BUTTON_CMOS_ADDRESS' - Variants of the corresponding variables without the `_BUTTON' - suffix, used to support vendor-specific power buttons. *Note - Vendor power-on keys::. - -`GRUB_DISTRIBUTOR' - Set by distributors of GRUB to their identifying name. This is - used to generate more informative menu entry titles. - -`GRUB_TERMINAL_INPUT' - Select the terminal input device. You may select multiple devices - here, separated by spaces. - - Valid terminal input names depend on the platform, but may include - `console' (PC BIOS and EFI consoles), `serial' (serial terminal), - `ofconsole' (Open Firmware console), `at_keyboard' (PC AT - keyboard, mainly useful with Coreboot), or `usb_keyboard' (USB - keyboard using the HID Boot Protocol, for cases where the firmware - does not handle this). - - The default is to use the platform's native terminal input. - -`GRUB_TERMINAL_OUTPUT' - Select the terminal output device. You may select multiple - devices here, separated by spaces. - - Valid terminal output names depend on the platform, but may include - `console' (PC BIOS and EFI consoles), `serial' (serial terminal), - `gfxterm' (graphics-mode output), `ofconsole' (Open Firmware - console), or `vga_text' (VGA text output, mainly useful with - Coreboot). - - The default is to use the platform's native terminal input. - -`GRUB_TERMINAL' - If this option is set, it overrides both `GRUB_TERMINAL_INPUT' and - `GRUB_TERMINAL_OUTPUT' to the same value. - -`GRUB_SERIAL_COMMAND' - A command to configure the serial port when using the serial - console. *Note serial::. Defaults to `serial'. - -`GRUB_CMDLINE_LINUX' - Command-line arguments to add to menu entries for the Linux kernel. - -`GRUB_CMDLINE_LINUX_DEFAULT' - Unless `GRUB_DISABLE_LINUX_RECOVERY' is set, two menu entries will - be generated for each Linux kernel: one default entry and one - entry for recovery mode. This option lists command-line arguments - to add only to the default menu entry, after those listed in - `GRUB_CMDLINE_LINUX'. - -`GRUB_CMDLINE_NETBSD' -`GRUB_CMDLINE_NETBSD_DEFAULT' - As `GRUB_CMDLINE_LINUX' and `GRUB_CMDLINE_LINUX_DEFAULT', but for - NetBSD. - -`GRUB_DISABLE_LINUX_UUID' - Normally, `grub-mkconfig' will generate menu entries that use - universally-unique identifiers (UUIDs) to identify the root - filesystem to the Linux kernel, using a `root=UUID=...' kernel - parameter. This is usually more reliable, but in some cases it - may not be appropriate. To disable the use of UUIDs, set this - option to `true'. - -`GRUB_DISABLE_LINUX_RECOVERY' - Disable the generation of recovery mode menu entries for Linux. - -`GRUB_DISABLE_NETBSD_RECOVERY' - Disable the generation of recovery mode menu entries for NetBSD. - -`GRUB_GFXMODE' - Set the resolution used on the `gfxterm' graphical terminal. Note - that you can only use modes which your graphics card supports via - VESA BIOS Extensions (VBE), so for example native LCD panel - resolutions may not be available. The default is `640x480'. - -`GRUB_BACKGROUND' - Set a background image for use with the `gfxterm' graphical - terminal. The value of this option must be a file readable by - GRUB at boot time, and it must end with `.png', `.tga', `.jpg', or - `.jpeg'. The image will be scaled if necessary to fit the screen. - -`GRUB_THEME' - Set a theme for use with the `gfxterm' graphical terminal. *Note - Themes::. - -`GRUB_GFXPAYLOAD_LINUX' - Set to `text' to force the Linux kernel to boot in normal text - mode, `keep' to preserve the graphics mode set using - `GRUB_GFXMODE', `WIDTHxHEIGHT'[`xDEPTH'] to set a particular - graphics mode, or a sequence of these separated by commas or - semicolons to try several modes in sequence. - - Depending on your kernel, your distribution, your graphics card, - and the phase of the moon, note that using this option may cause - GNU/Linux to suffer from various display problems, particularly - during the early part of the boot sequence. If you have problems, - simply unset this option and GRUB will tell Linux to boot in - normal text mode. - -`GRUB_DISABLE_OS_PROBER' - Normally, `grub-mkconfig' will try to use the external `os-prober' - program, if installed, to discover other operating systems - installed on the same system and generate appropriate menu entries - for them. Set this option to `true' to disable this. - -`GRUB_INIT_TUNE' - Play a tune on the speaker when GRUB starts. This is particularly - useful for users unable to see the screen. The value of this - option is passed directly to *note play::. - - For more detailed customisation of `grub-mkconfig''s output, you may -edit the scripts in `/etc/grub.d' directly. `/etc/grub.d/40_custom' is -particularly useful for adding entire custom menu entries; simply type -the menu entries you want to add at the end of that file, making sure -to leave at least the first two lines intact. - - -File: grub.info, Node: Shell-like scripting, Prev: Simple configuration, Up: Configuration - -5.2 Writing full configuration files directly -============================================= - - -File: grub.info, Node: Serial terminal, Next: Vendor power-on keys, Prev: Network, Up: Top - -6 Using GRUB via a serial line -****************************** - -This chapter describes how to use the serial terminal support in GRUB. - - If you have many computers or computers with no display/keyboard, it -could be very useful to control the computers through serial -communications. To connect one computer with another via a serial line, -you need to prepare a null-modem (cross) serial cable, and you may need -to have multiport serial boards, if your computer doesn't have extra -serial ports. In addition, a terminal emulator is also required, such as -minicom. Refer to a manual of your operating system, for more -information. - - As for GRUB, the instruction to set up a serial terminal is quite -simple. First of all, make sure that you haven't specified the option -`--disable-serial' to the configure script when you built your GRUB -images. If you get them in binary form, probably they have serial -terminal support already. - - Then, initialize your serial terminal after GRUB starts up. Here is -an example: - - grub> serial --unit=0 --speed=9600 - grub> terminal serial - - The command `serial' initializes the serial unit 0 with the speed -9600bps. The serial unit 0 is usually called `COM1', so, if you want to -use COM2, you must specify `--unit=1' instead. This command accepts -many other options, so please refer to *note serial::, for more details. - - The command `terminal' (*note terminal::) chooses which type of -terminal you want to use. In the case above, the terminal will be a -serial terminal, but you can also pass `console' to the command, as -`terminal serial console'. In this case, a terminal in which you press -any key will be selected as a GRUB terminal. - - However, note that GRUB assumes that your terminal emulator is -compatible with VT100 by default. This is true for most terminal -emulators nowadays, but you should pass the option `--dumb' to the -command if your terminal emulator is not VT100-compatible or implements -few VT100 escape sequences. If you specify this option then GRUB -provides you with an alternative menu interface, because the normal -menu requires several fancy features of your terminal. - - -File: grub.info, Node: Vendor power-on keys, Next: Preset Menu, Prev: Serial terminal, Up: Top - -7 Using GRUB with vendor power-on keys -************************************** - -Some laptop vendor provide an additional power-on button which boots -another OS. GRUB supports such buttons with GRUB_TIMEOUT_BUTTON, -GRUB_DEFAULT_BUTTON, GRUB_HIDDEN_TIMEOUT_BUTTON and -GRUB_BUTTON_CMOS_ADDRESS variables in default/grub. -GRUB_TIMEOUT_BUTTON, GRUB_DEFAULT_BUTTON and GRUB_HIDDEN_TIMEOUT_BUTTON -are used instead of corresponding variables without _BUTTON suffix when -powered using special button. GRUB_BUTTON_CMOS_ADDRESS is vendor -specific and partially model-specific. Values known to GRUB team are: - -<Dell XPS M1530> - 85:3 - - To take full advantage of this function install GRUB into MBR. - - -File: grub.info, Node: Filesystem, Next: Interface, Prev: Images, Up: Top - -8 Filesystem syntax and semantics -********************************* - -GRUB uses a special syntax for specifying disk drives which can be -accessed by BIOS. Because of BIOS limitations, GRUB cannot distinguish -between IDE, ESDI, SCSI, or others. You must know yourself which BIOS -device is equivalent to which OS device. Normally, that will be clear if -you see the files in a device or use the command `find' (*note find::). - -* Menu: - -* Device syntax:: How to specify devices -* File name syntax:: How to specify files -* Block list syntax:: How to specify block lists - - -File: grub.info, Node: Device syntax, Next: File name syntax, Up: Filesystem - -8.1 How to specify devices -========================== - -The device syntax is like this: - - `(DEVICE[,PART-NUM][,BSD-SUBPART-LETTER])' - - `[]' means the parameter is optional. DEVICE should be either `fd' -or `hd' followed by a digit, like `fd0'. But you can also set DEVICE -to a hexadecimal or a decimal number which is a BIOS drive number, so -the following are equivalent: - - (hd0) - (0x80) - (128) - - PART-NUM represents the partition number of DEVICE, starting from -one for primary partitions and from five for extended partitions, and -BSD-SUBPART-LETTER represents the BSD disklabel subpartition, such as -`a' or `e'. - - A shortcut for specifying BSD subpartitions is -`(DEVICE,BSD-SUBPART-LETTER)', in this case, GRUB searches for the -first PC partition containing a BSD disklabel, then finds the -subpartition BSD-SUBPART-LETTER. Here is an example: - - (hd0,a) - - The syntax `(hd0)' represents using the entire disk (or the MBR when -installing GRUB), while the syntax `(hd0,1)' represents using the first -partition of the disk (or the boot sector of the partition when -installing GRUB). - - If you enabled the network support, the special drive, `(nd)', is -also available. Before using the network drive, you must initialize the -network. *Note Network::, for more information. - - If you boot GRUB from a CD-ROM, `(cd)' is available. *Note Making a -GRUB bootable CD-ROM::, for details. - - -File: grub.info, Node: File name syntax, Next: Block list syntax, Prev: Device syntax, Up: Filesystem - -8.2 How to specify files -======================== - -There are two ways to specify files, by "absolute file name" and by -"block list". - - An absolute file name resembles a Unix absolute file name, using `/' -for the directory separator (not `\' as in DOS). One example is -`(hd0,1)/boot/grub/grub.cfg'. This means the file `/boot/grub/grub.cfg' -in the first partition of the first hard disk. If you omit the device -name in an absolute file name, GRUB uses GRUB's "root device" -implicitly. So if you set the root device to, say, `(hd1,1)' by the -command `root' (*note root::), then `/boot/kernel' is the same as -`(hd1,1)/boot/kernel'. - - -File: grub.info, Node: Block list syntax, Prev: File name syntax, Up: Filesystem - -8.3 How to specify block lists -============================== - -A block list is used for specifying a file that doesn't appear in the -filesystem, like a chainloader. The syntax is -`[OFFSET]+LENGTH[,[OFFSET]+LENGTH]...'. Here is an example: - - `0+100,200+1,300+300' - - This represents that GRUB should read blocks 0 through 99, block 200, -and blocks 300 through 599. If you omit an offset, then GRUB assumes -the offset is zero. - - Like the file name syntax (*note File name syntax::), if a blocklist -does not contain a device name, then GRUB uses GRUB's "root device". So -`(hd0,2)+1' is the same as `+1' when the root device is `(hd0,2)'. - - -File: grub.info, Node: Interface, Next: Commands, Prev: Filesystem, Up: Top - -9 GRUB's user interface -*********************** - -GRUB has both a simple menu interface for choosing preset entries from a -configuration file, and a highly flexible command-line for performing -any desired combination of boot commands. - - GRUB looks for its configuration file as soon as it is loaded. If one -is found, then the full menu interface is activated using whatever -entries were found in the file. If you choose the "command-line" menu -option, or if the configuration file was not found, then GRUB drops to -the command-line interface. - -* Menu: - -* Command-line interface:: The flexible command-line interface -* Menu interface:: The simple menu interface -* Menu entry editor:: Editing a menu entry - - -File: grub.info, Node: Command-line interface, Next: Menu interface, Up: Interface - -9.1 The flexible command-line interface -======================================= - -The command-line interface provides a prompt and after it an editable -text area much like a command-line in Unix or DOS.

The commands (*note Command-line and menu -entry commands::) are a subset of those available in the configuration -file, used with exactly the same syntax. - - Cursor movement and editing of the text on the line can be done via a -subset of the functions available in the Bash shell: - -<C-f> -<PC right key> - Move forward one character. - -<C-b> -<PC left key> - Move back one character. - -<C-a> -<HOME> - Move to the start of the line. - -<C-e> -<END> - Move the the end of the line. - -<C-d> -<DEL> - Delete the character underneath the cursor. - -<C-h> -<BS> - Delete the character to the left of the cursor. - -<C-k> - Kill the text from the current cursor position to the end of the - line. - -<C-u> - Kill backward from the cursor to the beginning of the line. - -<C-y> - Yank the killed text back into the buffer at the cursor. - -<C-p> -<PC up key> - Move up through the history list. - -<C-n> -<PC down key> - Move down through the history list. - - When typing commands interactively, if the cursor is within or before -the first word in the command-line, pressing the <TAB> key (or <C-i>) -will display a listing of the available commands, and if the cursor is -after the first word, the `<TAB>' will provide a completion listing of -disks, partitions, and file names depending on the context. Note that -to obtain a list of drives, one must open a parenthesis, as `root ('. - - Note that you cannot use the completion functionality in the TFTP -filesystem. This is because TFTP doesn't support file name listing for -the security. - - -File: grub.info, Node: Command-line interface-Footnotes, Up: Command-line interface - - (1) However, this behavior will be changed in the future version, in -a user-invisible way. - - -File: grub.info, Node: Menu interface, Next: Menu entry editor, Prev: Command-line interface, Up: Interface - -9.2 The simple menu interface -============================= - -The menu interface is quite easy to use. Its commands are both -reasonably intuitive and described on screen. - - Basically, the menu interface provides a list of "boot entries" to -the user to choose from. Use the arrow keys to select the entry of -choice, then press <RET> to run it. An optional timeout is available -to boot the default entry (the first one if not set), which is aborted -by pressing any key. - - Commands are available to enter a bare command-line by pressing <c> -(which operates exactly like the non-config-file version of GRUB, but -allows one to return to the menu if desired by pressing <ESC>) or to -edit any of the "boot entries" by pressing <e>. - - If you protect the menu interface with a password (*note Security::), -all you can do is choose an entry by pressing <RET>, or press <p> to -enter the password. - - -File: grub.info, Node: Menu entry editor, Prev: Menu interface, Up: Interface - -9.3 Editing a menu entry -======================== - -The menu entry editor looks much like the main menu interface, but the -lines in the menu are individual commands in the selected entry instead -of entry names. - - If an <ESC> is pressed in the editor, it aborts all the changes made -to the configuration entry and returns to the main menu interface. - - When a particular line is selected, the editor places the user in a -special version of the GRUB command-line to edit that line. When the -user hits <RET>, GRUB replaces the line in question in the boot entry -with the changes (unless it was aborted via <ESC>, in which case the -changes are thrown away). - - If you want to add a new line to the menu entry, press <o> if adding -a line after the current line or press <O> if before the current line. - - To delete a line, hit the key <d>.

See - `http://sources.redhat.com/binutils/', to obtain information on - how to get the latest version. - - GRUB is available from the GNU alpha archive site -`ftp://alpha.gnu.org/gnu/grub' or any of its mirrors. The file will be -named grub-version.tar.gz. The current version is 1.98, so the file you -should grab is: - - `ftp://alpha.gnu.org/gnu/grub/grub-1.98.tar.gz' - - To unbundle GRUB use the instruction: - - zcat grub-1.98.tar.gz | tar xvf - - - which will create a directory called `grub-1.98' with all the -sources. You can look at the file `INSTALL' for detailed instructions -on how to build and install GRUB, but you should be able to just do: - - cd grub-1.98 - ./configure - make install - - Also, the latest version is available from the SVN.

Take a look at this -list below before you submit bugs: - - 1. Before getting unsettled, read this manual through and through. - Also, see the GNU GRUB FAQ - (http://www.gnu.org/software/grub/grub-faq.html). - - 2. Always mention the information on your GRUB. The version number - and the configuration are quite important. If you build it - yourself, write the options specified to the configure script and - your operating system, including the versions of gcc and binutils. - - 3. If you have trouble with the installation, inform us of how you - installed GRUB. Don't omit error messages, if any. Just `GRUB hangs - up when it boots' is not enough. - - The information on your hardware is also essential. These are - especially important: the geometries and the partition tables of - your hard disk drives and your BIOS. - - 4. If GRUB cannot boot your operating system, write down _everything_ - you see on the screen. Don't paraphrase them, like `The foo OS - crashes with GRUB, even though it can boot with the bar boot - loader just fine'. Mention the commands you executed, the messages - printed by them, and information on your operating system - including the version number. - - 5. Explain what you wanted to do. It is very useful to know your - purpose and your wish, and how GRUB didn't satisfy you. - - 6. If you can investigate the problem yourself, please do. That will - give you and us much more information on the problem. Attaching a - patch is even better. - - When you attach a patch, make the patch in unified diff format, and - write ChangeLog entries. But, even when you make a patch, don't - forget to explain the problem, so that we can understand what your - patch is for. - - 7. Write down anything that you think might be related. Please - understand that we often need to reproduce the same problem you - encounterred in our environment. So your information should be - sufficient for us to do the same thing--Don't forget that we - cannot see your computer directly. If you are not sure whether to - state a fact or leave it out, state it! Reporting too many things - is much better than omitting something important. - - If you follow the guideline above, submit a report to the Bug -Tracking System (http://savannah.gnu.org/bugs/?group=grub). -Alternatively, you can submit a report via electronic mail to -<bug-grub@gnu.org>, but we strongly recommend that you use the Bug -Tracking System, because e-mail can be passed over easily. - - Once we get your report, we will try to fix the bugs. - - -File: grub.info, Node: Future, Next: Internals, Prev: Reporting bugs, Up: Top - -Appendix C Where GRUB will go -***************************** - -We started the next generation of GRUB, GRUB 2.

Secondarily, this License preserves for the - author and publisher a way to get credit for their work, while not - being considered responsible for modifications made by others. - - This License is a kind of "copyleft", which means that derivative - works of the document must themselves be free in the same sense. - It complements the GNU General Public License, which is a copyleft - license designed for free software. - - We have designed this License in order to use it for manuals for - free software, because free software needs free documentation: a - free program should come with manuals providing the same freedoms - that the software does. But this License is not limited to - software manuals; it can be used for any textual work, regardless - of subject matter or whether it is published as a printed book. - We recommend this License principally for works whose purpose is - instruction or reference. - - 1. APPLICABILITY AND DEFINITIONS - - This License applies to any manual or other work, in any medium, - that contains a notice placed by the copyright holder saying it - can be distributed under the terms of this License. Such a notice - grants a world-wide, royalty-free license, unlimited in duration, - to use that work under the conditions stated herein. The - "Document", below, refers to any such manual or work. Any member - of the public is a licensee, and is addressed as "you". You - accept the license if you copy, modify or distribute the work in a - way requiring permission under copyright law. - - A "Modified Version" of the Document means any work containing the - Document or a portion of it, either copied verbatim, or with - modifications and/or translated into another language. - - A "Secondary Section" is a named appendix or a front-matter section - of the Document that deals exclusively with the relationship of the - publishers or authors of the Document to the Document's overall - subject (or to related matters) and contains nothing that could - fall directly within that overall subject. (Thus, if the Document - is in part a textbook of mathematics, a Secondary Section may not - explain any mathematics.) The relationship could be a matter of - historical connection with the subject or with related matters, or - of legal, commercial, philosophical, ethical or political position - regarding them. - - The "Invariant Sections" are certain Secondary Sections whose - titles are designated, as being those of Invariant Sections, in - the notice that says that the Document is released under this - License. If a section does not fit the above definition of - Secondary then it is not allowed to be designated as Invariant. - The Document may contain zero Invariant Sections. If the Document - does not identify any Invariant Sections then there are none. - - The "Cover Texts" are certain short passages of text that are - listed, as Front-Cover Texts or Back-Cover Texts, in the notice - that says that the Document is released under this License. A - Front-Cover Text may be at most 5 words, and a Back-Cover Text may - be at most 25 words. - - A "Transparent" copy of the Document means a machine-readable copy, - represented in a format whose specification is available to the - general public, that is suitable for revising the document - straightforwardly with generic text editors or (for images - composed of pixels) generic paint programs or (for drawings) some - widely available drawing editor, and that is suitable for input to - text formatters or for automatic translation to a variety of - formats suitable for input to text formatters. A copy made in an - otherwise Transparent file format whose markup, or absence of - markup, has been arranged to thwart or discourage subsequent - modification by readers is not Transparent. An image format is - not Transparent if used for any substantial amount of text. A - copy that is not "Transparent" is called "Opaque". - - Examples of suitable formats for Transparent copies include plain - ASCII without markup, Texinfo input format, LaTeX input format, - SGML or XML using a publicly available DTD, and - standard-conforming simple HTML, PostScript or PDF designed for - human modification. Examples of transparent image formats include - PNG, XCF and JPG. Opaque formats include proprietary formats that - can be read and edited only by proprietary word processors, SGML or - XML for which the DTD and/or processing tools are not generally - available, and the machine-generated HTML, PostScript or PDF - produced by some word processors for output purposes only. - - The "Title Page" means, for a printed book, the title page itself, - plus such following pages as are needed to hold, legibly, the - material this License requires to appear in the title page. For - works in formats which do not have any title page as such, "Title - Page" means the text near the most prominent appearance of the - work's title, preceding the beginning of the body of the text. - - A section "Entitled XYZ" means a named subunit of the Document - whose title either is precisely XYZ or contains XYZ in parentheses - following text that translates XYZ in another language. (Here XYZ - stands for a specific section name mentioned below, such as - "Acknowledgements", "Dedications", "Endorsements", or "History".) - To "Preserve the Title" of such a section when you modify the - Document means that it remains a section "Entitled XYZ" according - to this definition. - - The Document may include Warranty Disclaimers next to the notice - which states that this License applies to the Document. These - Warranty Disclaimers are considered to be included by reference in - this License, but only as regards disclaiming warranties: any other - implication that these Warranty Disclaimers may have is void and - has no effect on the meaning of this License. - - 2. VERBATIM COPYING - - You may copy and distribute the Document in any medium, either - commercially or noncommercially, provided that this License, the - copyright notices, and the license notice saying this License - applies to the Document are reproduced in all copies, and that you - add no other conditions whatsoever to those of this License. You - may not use technical measures to obstruct or control the reading - or further copying of the copies you make or distribute. However, - you may accept compensation in exchange for copies. If you - distribute a large enough number of copies you must also follow - the conditions in section 3. - - You may also lend copies, under the same conditions stated above, - and you may publicly display copies. - - 3. COPYING IN QUANTITY - - If you publish printed copies (or copies in media that commonly - have printed covers) of the Document, numbering more than 100, and - the Document's license notice requires Cover Texts, you must - enclose the copies in covers that carry, clearly and legibly, all - these Cover Texts: Front-Cover Texts on the front cover, and - Back-Cover Texts on the back cover. Both covers must also clearly - and legibly identify you as the publisher of these copies. The - front cover must present the full title with all words of the - title equally prominent and visible. You may add other material - on the covers in addition. Copying with changes limited to the - covers, as long as they preserve the title of the Document and - satisfy these conditions, can be treated as verbatim copying in - other respects. - - If the required texts for either cover are too voluminous to fit - legibly, you should put the first ones listed (as many as fit - reasonably) on the actual cover, and continue the rest onto - adjacent pages. - - If you publish or distribute Opaque copies of the Document - numbering more than 100, you must either include a - machine-readable Transparent copy along with each Opaque copy, or - state in or with each Opaque copy a computer-network location from - which the general network-using public has access to download - using public-standard network protocols a complete Transparent - copy of the Document, free of added material. If you use the - latter option, you must take reasonably prudent steps, when you - begin distribution of Opaque copies in quantity, to ensure that - this Transparent copy will remain thus accessible at the stated - location until at least one year after the last time you - distribute an Opaque copy (directly or through your agents or - retailers) of that edition to the public. - - It is requested, but not required, that you contact the authors of - the Document well before redistributing any large number of - copies, to give them a chance to provide you with an updated - version of the Document. - - 4. MODIFICATIONS - - You may copy and distribute a Modified Version of the Document - under the conditions of sections 2 and 3 above, provided that you - release the Modified Version under precisely this License, with - the Modified Version filling the role of the Document, thus - licensing distribution and modification of the Modified Version to - whoever possesses a copy of it. In addition, you must do these - things in the Modified Version: - - A. Use in the Title Page (and on the covers, if any) a title - distinct from that of the Document, and from those of - previous versions (which should, if there were any, be listed - in the History section of the Document). You may use the - same title as a previous version if the original publisher of - that version gives permission. - - B. List on the Title Page, as authors, one or more persons or - entities responsible for authorship of the modifications in - the Modified Version, together with at least five of the - principal authors of the Document (all of its principal - authors, if it has fewer than five), unless they release you - from this requirement. - - C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. - - D. Preserve all the copyright notices of the Document. - - E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. - - F. Include, immediately after the copyright notices, a license - notice giving the public permission to use the Modified - Version under the terms of this License, in the form shown in - the Addendum below. - - G. Preserve in that license notice the full lists of Invariant - Sections and required Cover Texts given in the Document's - license notice. - - H. Include an unaltered copy of this License. - - I. Preserve the section Entitled "History", Preserve its Title, - and add to it an item stating at least the title, year, new - authors, and publisher of the Modified Version as given on - the Title Page. If there is no section Entitled "History" in - the Document, create one stating the title, year, authors, - and publisher of the Document as given on its Title Page, - then add an item describing the Modified Version as stated in - the previous sentence. - - J. Preserve the network location, if any, given in the Document - for public access to a Transparent copy of the Document, and - likewise the network locations given in the Document for - previous versions it was based on. These may be placed in - the "History" section. You may omit a network location for a - work that was published at least four years before the - Document itself, or if the original publisher of the version - it refers to gives permission. - - K. For any section Entitled "Acknowledgements" or "Dedications", - Preserve the Title of the section, and preserve in the - section all the substance and tone of each of the contributor - acknowledgements and/or dedications given therein. - - L. Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section - titles. - - M. Delete any section Entitled "Endorsements". Such a section - may not be included in the Modified Version. - - N. Do not retitle any existing section to be Entitled - "Endorsements" or to conflict in title with any Invariant - Section. - - O. Preserve any Warranty Disclaimers. - - If the Modified Version includes new front-matter sections or - appendices that qualify as Secondary Sections and contain no - material copied from the Document, you may at your option - designate some or all of these sections as invariant. To do this, - add their titles to the list of Invariant Sections in the Modified - Version's license notice. These titles must be distinct from any - other section titles. - - You may add a section Entitled "Endorsements", provided it contains - nothing but endorsements of your Modified Version by various - parties--for example, statements of peer review or that the text - has been approved by an organization as the authoritative - definition of a standard. - - You may add a passage of up to five words as a Front-Cover Text, - and a passage of up to 25 words as a Back-Cover Text, to the end - of the list of Cover Texts in the Modified Version. Only one - passage of Front-Cover Text and one of Back-Cover Text may be - added by (or through arrangements made by) any one entity. If the - Document already includes a cover text for the same cover, - previously added by you or by arrangement made by the same entity - you are acting on behalf of, you may not add another; but you may - replace the old one, on explicit permission from the previous - publisher that added the old one. - - The author(s) and publisher(s) of the Document do not by this - License give permission to use their names for publicity for or to - assert or imply endorsement of any Modified Version. - - 5. COMBINING DOCUMENTS - - You may combine the Document with other documents released under - this License, under the terms defined in section 4 above for - modified versions, provided that you include in the combination - all of the Invariant Sections of all of the original documents, - unmodified, and list them all as Invariant Sections of your - combined work in its license notice, and that you preserve all - their Warranty Disclaimers. - - The combined work need only contain one copy of this License, and - multiple identical Invariant Sections may be replaced with a single - copy. If there are multiple Invariant Sections with the same name - but different contents, make the title of each such section unique - by adding at the end of it, in parentheses, the name of the - original author or publisher of that section if known, or else a - unique number. Make the same adjustment to the section titles in - the list of Invariant Sections in the license notice of the - combined work. - - In the combination, you must combine any sections Entitled - "History" in the various original documents, forming one section - Entitled "History"; likewise combine any sections Entitled - "Acknowledgements", and any sections Entitled "Dedications". You - must delete all sections Entitled "Endorsements." - - 6. COLLECTIONS OF DOCUMENTS - - You may make a collection consisting of the Document and other - documents released under this License, and replace the individual - copies of this License in the various documents with a single copy - that is included in the collection, provided that you follow the - rules of this License for verbatim copying of each of the - documents in all other respects. - - You may extract a single document from such a collection, and - distribute it individually under this License, provided you insert - a copy of this License into the extracted document, and follow - this License in all other respects regarding verbatim copying of - that document. - - 7. AGGREGATION WITH INDEPENDENT WORKS - - A compilation of the Document or its derivatives with other - separate and independent documents or works, in or on a volume of - a storage or distribution medium, is called an "aggregate" if the - copyright resulting from the compilation is not used to limit the - legal rights of the compilation's users beyond what the individual - works permit. When the Document is included in an aggregate, this - License does not apply to the other works in the aggregate which - are not themselves derivative works of the Document. - - If the Cover Text requirement of section 3 is applicable to these - copies of the Document, then if the Document is less than one half - of the entire aggregate, the Document's Cover Texts may be placed - on covers that bracket the Document within the aggregate, or the - electronic equivalent of covers if the Document is in electronic - form. Otherwise they must appear on printed covers that bracket - the whole aggregate. - - 8. TRANSLATION - - Translation is considered a kind of modification, so you may - distribute translations of the Document under the terms of section - 4. Replacing Invariant Sections with translations requires special - permission from their copyright holders, but you may include - translations of some or all Invariant Sections in addition to the - original versions of these Invariant Sections. You may include a - translation of this License, and all the license notices in the - Document, and any Warranty Disclaimers, provided that you also - include the original English version of this License and the - original versions of those notices and disclaimers. In case of a - disagreement between the translation and the original version of - this License or a notice or disclaimer, the original version will - prevail. - - If a section in the Document is Entitled "Acknowledgements", - "Dedications", or "History", the requirement (section 4) to - Preserve its Title (section 1) will typically require changing the - actual title. - - 9. TERMINATION - - You may not copy, modify, sublicense, or distribute the Document - except as expressly provided for under this License. Any other - attempt to copy, modify, sublicense or distribute the Document is - void, and will automatically terminate your rights under this - License. However, parties who have received copies, or rights, - from you under this License will not have their licenses - terminated so long as such parties remain in full compliance. - - 10. FUTURE REVISIONS OF THIS LICENSE - - The Free Software Foundation may publish new, revised versions of - the GNU Free Documentation License from time to time. Such new - versions will be similar in spirit to the present version, but may - differ in detail to address new problems or concerns. See - `http://www.gnu.org/copyleft/'. - - Each version of the License is given a distinguishing version - number. If the Document specifies that a particular numbered - version of this License "or any later version" applies to it, you - have the option of following the terms and conditions either of - that specified version or of any later version that has been - published (not as a draft) by the Free Software Foundation. If - the Document does not specify a version number of this License, - you may choose any version ever published (not as a draft) by the - Free Software Foundation. - -D.1.1 ADDENDUM: How to use this License for your documents ----------------------------------------------------------- - -To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and license -notices just after the title page: - - Copyright (C) YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.2 - or any later version published by the Free Software Foundation; - with no Invariant Sections, no Front-Cover Texts, and no Back-Cover - Texts. A copy of the license is included in the section entitled ``GNU - Free Documentation License''. - - If you have Invariant Sections, Front-Cover Texts and Back-Cover -Texts, replace the "with...Texts." line with this: - - with the Invariant Sections being LIST THEIR TITLES, with - the Front-Cover Texts being LIST, and with the Back-Cover Texts - being LIST. - - If you have Invariant Sections without Cover Texts, or some other -combination of the three, merge those two alternatives to suit the -situation. - - If your document contains nontrivial examples of program code, we -recommend releasing these examples in parallel under your choice of -free software license, such as the GNU General Public License, to -permit their use in free software. - - -File: grub.info, Node: Index, Prev: Copying This Manual, Up: Top - -Index -***** - - -* Menu: - -* acpi: acpi.
