LILO !!!LILO NAME SYNOPSIS DESCRIPTION BOOT OPTIONS INCOMPATIBILITIES BUGS SEE ALSO AUTHORS ---- !!NAME lilo - install boot loader !!SYNOPSIS Main function: __/sbin/lilo__ - install boot loader Auxiliary uses: __/sbin/lilo -q__ - query map__ /sbin/lilo -R__ - set default command line for next reboot__ /sbin/lilo -I__ - inquire path name of current kernel__ /sbin/lilo -A__ - activate a partition / show active partition__ /sbin/lilo -M [[-z]__ - write a Master Boot Record on a device - or clear the device serial number__ /sbin/lilo -T__ - tell more about specified topic__ /sbin/lilo {-u|-U}__ - uninstall lilo !!DESCRIPTION __lilo__ installs a boot loader that will be activated next time you boot. It has lots of options. __-A__ ''master-device [[ N ]'' Inquire of active partition on device ''master-device''; e.g., '' __-b__ ''bootdev'' Specify the boot device; i.e., where the boot loader will be installed. __-c__ Enable map compaction. This will merge read requests from adjacent sectors. Speeds up the booting (especially from floppy). __-C__ ''config-file'' __lilo__ reads its instructions about what files to map from the specified configuration file. This option overrides the use of the default config file, ''/etc/lilo.conf''. __-d__ ''delay'' Specifies the delay time in tenths of a second (20 = 2 sec) before automatically booting the first image. Gives you time to interrupt the automatic boot process with Shift, Alt, Ctrl, !ScrollLock, or !CapsLock. If interrupted, the `boot:' prompt is displayed. This switch is overriden by the appearance of ''prompt'' in the config-file. __-D__ ''label'' Use the kernel with the given label, instead of the first one in the list, as the default kernel to boot. __-f__ ''disk-tab'' Specify disk geometry parameter file. (The default is ''/etc/disktab''.) __-g__ Generate sector/head/cylinder (geometric) disk addresses. Limited to cylinders up to 1023. Forces compatibility with older versions of LILO. __-i__ ''boot-loader'' Specify a file to be used as the new boot loader. (The default is ''/boot/boot.b''.) __-I__ ''label'' The label of the running kernel can be found in the environment variable BOOT_IMAGE after startup, or in the pseudo-file `/proc/cmdline'. This command will print path name of the corresponding kernel file, or of any initial ramdisk file ( __-l__ Generate 24-bit linear sector addresses instead of sector/head/cylinder addresses. __-L__ Generate 32-bit Logical Block Addresses instead of C:H:S addresses, allowing access to all partitions on disks with more than 1024 cylinders. __-m__ ''map-file'' Use specified map file instead of the default. __-M__ ''master-device [[ mbr-file ]'' Install a Master Boot Record on the device specified as ''master-device''. The new MBR is copied by default from ''master-device'' is undistrubed. If no device serial number is present, then generate one and write it to the MBR. __-p__ Require interactive entry of all passwords specified as ____ in the configuration file. __-P__ ''{fix|ignore}'' Fix (or ignore) `corrupt' partition tables, i.e., partition tables with linear and sector/head/cylinder addresses that do not correspond. __-q__ List the currently mapped files. __lilo__ maintains a file, by default ''/boot/map'', containing the name and location of the kernel(s) to boot. This option will list the names therein. Use with __-v__ for more detailed information about the installed boot loader. __-r__ ''root-directory'' Before doing anything else, do a ''chroot'' to the indicated directory. The new root directory must contain a ''/dev'' directory, and may need a ''/boot'' directory. It may also need an ''/etc/lilo.conf'' file. Used by the ''mkbootdisk'' shell script for creating a bootable floppy. __-R__ ''command line'' This option sets the default command for the boot loader the next time it executes. The boot loader will then erase this line: this is a once-only command. It is typically used in reboot scripts, just before calling `shutdown -r'. Used without any arguments, it will cancel a ''lock''-ed or ''fallback'' command line. __-s__ ''save-file'' When __lilo__ overwrites the boot sector, it preserves the old contents in a file, by default ''/boot/boot.NNNN'' where NNNN depends on the device. This option specifies an alternate save file for the boot sector. (Or, together with the __-u__ option, specifies from where to restore the boot sector.) __-S__ ''save-file'' Normally, __lilo__ will not overwrite an existing save file. This options says that overwriting is allowed. __-t__ Test only. Do not really write a new boot sector or map file. Use together with __-v__ to find out what __lilo__ is about to do. __-T__ ''option'' Print out system information, some of it extracted from the system bios. This is more convenient than booting the LILO diagnostic floppy on problem systems. ''option'' may be any one of the following: help - print a list of available diagnostics !ChRul - list the partition types subject to Change-Rules EBDA - list Extended BIOS Data Area information geom= __-u__ ''[[device-name]'' Uninstall ''lilo'' by copying the saved boot sector back. The '-s' and '-C' switches may be used with this option. The ''device-name'' is optional. A time-stamp is checked. __-U__ ''[[device-name]'' Idem, but do not check the time-stamp. __-v__ Increase verbosity. Giving one to five __-v__ options will make lilo more verbose, or use, __-v__ ''n'' (n=1..5) to set verbosity level '''n'''. __-V__ Print version number. __-w__ Suppress warning messages. __-x__ ''option'' For RAID installations only. The option may be any of the keywords ''none'', ''auto'', ''mbr-only'', or a comma separated list of additional boot devices (no spaces allowed in the list). __-z__ When used with the -M switch, clears the device serial number. Usually used in the following sequence to generate a new device serial number: lilo -z -M /dev/hda lilo -M /dev/hda The above command line options correspond to the key words in the config file indicated below. !!BOOT OPTIONS The options described here may be specified at on the command line when a kernel image is booted. These options are processed by LILO, and are removed from the command line passed to the kernel, unless otherwise noted. __lock__ Locks the command line, as though 'lock' had been specified in 'lilo.conf.' __mem=###[[,K,M]__ Specifies the maximum memory in the system in bytes, kilobytes, or megabytes. This option is not removed from the command line, and is always passed to the kernel. __nobd__ Suppresses collection of BIOS data. This option is reserved for use with non-IBM-compliant BIOS's which hang up with an Loading.........s __vga=[[ASK,EXT,EXTENDED,NORMAL]__ Allows overriding the default video mode upon kernel startup. !!INCOMPATIBILITIES __lilo__ is known to have problems with the ''reiserfs'' introduced with the 2.2.x kernels, unless the file system is mounted with the 'notail' option. This incompatibilty has been resolved with reiserfs 3.6.18 and lilo 21.6. Beginning with version 22.0, RAID installations write the boot record to the RAID partition. Conditional writing of MBRs may occur to aid in making the RAID set bootable in a recovery situation, but all default actions may be overridden. Action similar to previous versions is achieved using the `-x mbr-only' switch. !!BUGS Configuration file options `backup' and `force-backup' are not yet correctly implemented for RAID installations. Use of the default boot record backup mechanism seems to work okay, and should be used. !!SEE ALSO fdisk(8), lilo.conf(5), mkrescue(8), mkinitrd(8). The lilo distribution comes with very extensive documentation. This can be found in /usr/share/doc/lilo on Debian systems. (lilo 22.1) !!AUTHORS Werner Almesberger John Coffman ----
