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  ker-
              nel(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  direc-
              tory. 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  adja-
              cent sectors. Speeds up the booting (especially from floppy).

       -f disk-tab
              Specify disk geometry parameter file. (The default is /etc/disk-
              tab.)

       -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 correspond.

       -s save-file
              When lilo overwrites the boot sector, it preserves the old  con-
              tents  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
              corresponding path name on stdout.

       -V     Print version number.


       The  above command line options correspond to the key words in the con-
       fig file indicated below.


              -b bootdev      boot=bootdev

              -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
