Lenny - problème de Grub qui ne démarre pas automatiquement sur le noyau par d éfaut

Bonjour,

Sur un de mes serveur sous Lenny (à jour), j'ai un comportement étran=
ge de Grub.
Lorsque je le rédémarre, il reste sur le menu sans amorcer le noyau c=
orrespondant au
défaut configuré (ici default 0).

Il faut donc appuyer sur la touche entrée pour qu'il démarre, ce qui =
est ennuyeux

La version de grub est la suivante :

dpkg -l | grep grub
ii grub 0.97-47lenny=
2
GRand Unified Bootloader (Legacy version)
ii grub-common 1.96+2008072=
4-16
GRand Unified Bootloader, version 2 (common files)
rc grub-pc 1.96+2008072=
4-16
GRand Unified Bootloader, version 2 (PC/BIOS version)

Si quelqu'un a une piste, je suis preneur

D'avance merci,

Cordialement,

Sylvain

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0,=
and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default =
entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or=
your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default=
entry
# (normally the first entry defined).

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=/dev/hda1 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,0)

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with t=
he
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(single-user) single
# altoptions=(single-user mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=false

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false

## ## End Default Options ##
