LILO con múltiples kernels
Soy nuevo en Linux, apenas 6 meses.
Durante 4, usé Mandrake y sus asistentes. Cuando más o menos entendía qué
hacía, cambié a Debian.
Luego de pelearme durante un mes con los periféricos, decidí que era hora de
juagar en serio.
No puedo configurar el arranque de LILO con otro kernel. Me explico:
Instalé la imagen 2.4.18-bf2.4 que me da como opción el instalador de la
revisión 3.0 r2 Woody.
Con el APT cargué la 2.5.18-586tsc.
Según el sistema, estuvo bien, pero no me deja levantar la imagen 586 (tengo
un PIII 750 Mhz).
Inicia la carga, y se detiene con el siguiente mensaje (últimos 4 renglones,
donde empiezan mensajes de problemas):
request_module[block-major3]: Rooot not mounted
VFS: Cannot open root device "345" or 03:45
Please append a correct device "root=" boot option
Kernel panic: VFS: Unable mount root fs on 03:45
Leí LILO y todos sus manuales, HowTo de kernel y los etcéteras que se les
ocurran: Me rindo.
Adjunto el lilo.conf para que si alguien pueda tenderme una mano, me ayude.
Es mi intención en poco instalar el kernel 2.6. Si tengo problemas en un
arranque dual con algo que ya viene en la distribución, no quiero imaginar
qué me puede pasar con algo que compile.
Gracias.

# /etc/lilo.conf - See: `lilo(8)' and `lilo.conf(5)',
# --------------- `install-mbr(8)', `/usr/share/doc/lilo/',
# and `/usr/share/doc/mbr/'.
# +---------------------------------------------------------------+
# | !! Reminder !! |
# | |
# | Don't forget to run `lilo' after you make changes to this |
# | conffile, `/boot/bootmess.txt', or install a new kernel. The |
# | computer will most likely fail to boot if a kernel-image |
# | post-install script or you don't remember to run `lilo'. |

# Overrides the default mapping between harddisk names and the BIOS'
# harddisk order. Use with caution.
#disk=/dev/hde
# bios=0x81
#disk=/dev/sda
# bios=0x80
# 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.
#
boot=/dev/hda
# Specifies the device that should be mounted as root. (`/')
#
root=/dev/hdb5
# 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
# Look in /boot/ and in lilo.conf(5) manpage for details
#
install=/boot/boot-menu.b
# 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'.
