keep in mind, the contents of /boot are the result of a tarball i
moved on to this machine from another machine. this is not what originally
was on this machine prior to my mistake.

# | !! Reminder !! |

# | Don't forget to run `lilo' after you make changes to this |

# Specifies the boot device. This is where Lilo installs its boot
# block. It can be either a partition, or the raw device, in which
# case it installs in the MBR, and will overwrite the current MBR.

# Specifies the device that should be mounted as root. (`/')
#
root=/dev/hda3
# Enable map compaction:
# Tries to merge read requests for adjacent sectors into a single
# read request. This drastically reduces load time and keeps the
# map smaller. Using `compact' is especially recommended when
# booting from a floppy disk. It is disabled here by default
# because it doesn't always work.

# compact
# Installs the specified file as the new boot sector
# You have the choice between: bmp, compat, menu and text

# Specifies the location of the map file
#
map=/boot/map
# You can set a password here, and uncomment the `restricted' lines
# in the image definitions below to make it so that a password must
# be typed to boot anything but a default configuration. If a
# command line is given, other than one specified by an `append'
# statement in `lilo.conf', the password will be required, but a
# standard default boot will not require one.
#
# This will, for instance, prevent anyone with access to the
# console from booting with something like `Linux init=/bin/sh',
# and thus becoming `root' without proper authorization.
#
# Note that if you really need this type of security, you will
# likely also want to use `install-mbr' to reconfigure the MBR
# program, as well as set up your BIOS to disallow booting from
# removable disk or CD-ROM, then put a password on getting into the
# BIOS configuration as well. Please RTFM `install-mbr(8)'.
#
# password=tatercounter2000
# Specifies the number of deciseconds (0.1 seconds) LILO should
# wait before booting the first image.
#
delay=20
# You can put a customized boot message up if you like. If you use
# `prompt', and this computer may need to reboot unattended, you
# must specify a `timeout', or it will sit there forever waiting
# for a keypress. `single-key' goes with the `alias' lines in the
# `image' configurations below. eg: You can press `1' to boot
# `Linux', `2' to boot `LinuxOLD', if you uncomment the `alias'.
