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 {-u|-U} - uninstall lilo DESCRIPTION
lilo installs a boot loader that will be activated next time you boot. It has lots of options. -v Increase verbosity. Giving one or more -v options will make lilo more verbose. -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. -m map-file Use specified map file instead of the default. -C config-file lilo reads its instructions about what files to map from its config file, by default /etc/lilo.conf. This option can be used to specify a non-default config file. -d delay If you have specified several kernels, and press Shift at boot-time, the boot loader will present you with a choice of which system to boot. After a timeout period the first kernel in the list is booted. This option specifies the timeout delay in deciseconds. -D label Use the kernel with the given label, instead of the first one in the list, as the default kernel to boot. -r root-directory Before doing anything else, do a chroot to the indicated directory. Used for repairing a setup from a boot floppy. -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. -c Enable map compaction. This will merge read requests from adjacent sectors. Speeds up the booting (especially from floppy). -f disk-tab Specify disk geometry parameter file. (The default is /etc/disktab.) -i boot-sector Specify a file to be used as the new boot sector. (The default is /boot/boot.b.) -l Generate 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 greater than 8.4Gb. -P {fix|ignore} Fix (or ignore) `corrupt' partition tables, i.e., partition tables with linear and sector/head/cylinder addresses that do not corre- spond. -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. -u device-name Uninstall lilo, by copying the saved boot sector back. A time-stamp is checked. -U device-name Idem, but do not check the time-stamp. -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'. -I label The label of the running kernel can be found in the environment variable BOOT_IMAGE after startup. This command will print the cor- responding path name on stdout. -V Print version number. The above command line options correspond to the key words in the config file indicated below. -b bootdev boot=bootdev -c compact -d dsec delay=dsec -D label default=label -i bootsector install=bootsector -f file disktab=file -l linear -L lba32 -m mapfile map=mapfile -P fix fix-table -P ignore ignore-table -s file backup=file -S file force-backup=file -v verbose=level SEE ALSO
lilo.conf(5). The lilo distribution comes with very extensive documentation. AUTHOR
