You should be able to fix this by booting off the CD.
Not totally sure about Mandrake, haven't used it for some time, but you should be able to do the following:
At the boot prompt, type "linux rescue" and hit return.
boot: linux rescue
Once you get to a command prompt, you can chroot to wherever your system is mounted
(on RedHat and Fedora it is /mnt/sysimage) type 'chroot /mnt/sysimage'
% chroot /mnt/sysimage
Now, edit your lilo.conf file (Hope you can use vi)
% vi /etc/lilo.conf
Note: If you just need to increase the value of the timeout from 0 to 50, then use
the 'H', 'J', 'K', and 'L' keys to move your cursor overtop of the 0 after timeout=.
Just play around with those four keys until you are where you need to be.
Now hit the 'I' (that is I as in EYE) key and then the '5' key. Now hit 'Esc'. Now
hit ':' (that is 'Shift-;' ) then 'w' and 'q' and 'Enter'. You should now be back at a
After your vi session, you are ready to write the lilo
If you get something like:
Added DOS *
You did it right. Reboot.
Hope this helps,
