If you get LI at boot time, then your LILO boot loader is not able to find the Linux kernel in order to boot it. Boot from your woody CD (or other rescue disk), edit your lilo.conf file, and re-run lilo.
If you boot from a woody CD, just choose "bf24" as the boot option in order to use the 2.4.18 kernel. Let the menu come up, and then press Alt-F2 to get to the shell. Mount your root file system on /mnt (e.g. with mount /dev/hda1 /mnt or similar). Type chroot /mnt to temporarily change your root directory to your mounted file system, and then you should be able to access your text-mode editor, your /etc/lilo.conf file, and so on in a fairly normal fashion.
Make any necessary changes to your /etc/lilo.conf file. In particular, if you need to add lba32 to it, do so now. When you're done editing, run lilo. Then exit from the chroot shell, umount /mnt (be sure you're not sitting in it!), and reboot without the rescue disk.
