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.

It is normally also necessary to load some GRUB modules and set the +appropriate root device. Putting this together, we get something like +this, for a Windows system on the first partition of the first hard +disk: + +menuentry "Windows" { + insmod chain + insmod ntfs + set root=(hd0,1) + chainloader +1 +} + + On systems with multiple hard disks, an additional workaround may be +required. *Note DOS/Windows::. + + Chain-loading is only supported on PC BIOS and EFI platforms. + + +File: grub.info, Node: OS-specific notes, Prev: General boot methods, Up: Booting + +4.2 Some caveats on OS-specific issues +====================================== + +Here, we describe some caveats on several operating systems. + +* Menu: + +* GNU/Hurd:: +* GNU/Linux:: +* DOS/Windows:: +* SCO UnixWare:: +* QNX:: + + +File: grub.info, Node: GNU/Hurd, Next: GNU/Linux, Up: OS-specific notes + +4.2.1 GNU/Hurd +-------------- + +Since GNU/Hurd is Multiboot-compliant, it is easy to boot it; there is +nothing special about it.

Finally, run the command `boot' (*note boot::). + + *Caution:* If you use an initrd and specify the `mem=' option to the +kernel to let it use less than actual memory size, you will also have +to specify the same memory size to GRUB.

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. If that OS uses a special driver for the +disks, this probably won't work. + + Another problem arises if you installed more than one set of +DOS/Windows onto one disk, because they could be confused if there are +more than one primary partitions for DOS/Windows. Certainly you should +avoid doing this, but there is a solution if you do want to do so. Use +the partition hiding/unhiding technique. + + If GRUB "hides" a DOS (or Windows) partition (*note parttool::), DOS +(or Windows) will ignore the partition. If GRUB "unhides" a DOS (or +Windows) partition, DOS (or Windows) will detect the partition. Thus, +if you have installed DOS (or Windows) on the first and the second +partition of the first hard disk, and you want to boot the copy on the +first partition, do the following: + + parttool (hd0,1) hidden- + parttool (hd0,2) hidden+ + set root=(hd0,1) + chainloader +1 + parttool ${root} boot+ + boot + + +File: grub.info, Node: SCO UnixWare, Next: QNX, Prev: DOS/Windows, Up: OS-specific notes + +4.2.4 SCO UnixWare +------------------ + +It is known that the signature in the boot loader for SCO UnixWare is +wrong, so you will have to specify the option `--force' to +`chainloader' (*note chainloader::), like this: + + set root=(hd1,1) + chainloader --force +1 + parttool ${root} boot+ + boot + + +File: grub.info, Node: QNX, Prev: SCO UnixWare, Up: OS-specific notes + +4.2.5 QNX +--------- + +QNX seems to use a bigger boot loader, so you need to boot it up, like +this: + + set root=(hd1,2) + chainloader +4 + boot + + +File: grub.info, Node: Configuration, Next: Network, Prev: Booting, Up: Top + +5 Writing your own configuration file +************************************* + +GRUB is configured using `grub.cfg', usually located under +`/boot/grub'.

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. Each command is +immediately executed after it is entered(1) (*note Command-line +interface-Footnote-1::). 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>. Although GRUB unfortunately does +not support "undo", you can do almost the same thing by just returning +to the main menu. + + +File: grub.info, Node: Commands, Next: Troubleshooting, Prev: Interface, Up: Top + +10 The list of available commands +********************************* + +In this chapter, we list all commands that are available in GRUB. + + Commands belong to different groups.

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.
