first move the ISO to the fat32 partition
you should then backup your personal data. if you tar it up you can store it on the fat32 partition without losing permisions.
this can be done with the command below. just change /home/username to the dir or files you want to backup
tar cpO /home/username|lzma >/tmp/backup.tlz
and then move the backup.tlz to the fat32 partition
then you will need to add the installer initrd and kernel to lilo
you will ned to mount the ISO and copy them from it.
this can be done with the command below. just change fat32partition to thae actual name of the partition
mount -o loop /mnt/fat32partition/VL5.9*.iso /mnt/loop
cp /mnt/loop/isolinux/initrd.img /boot
cp /mnt/loop/isolinux/kernel/sata /boot
now copy and paste the command section below to fix lilo.conf
cat >>/etc/lilo.conf <<EOF
title vl install
root (hd0,0)
kernel /boot/sata root=/dev/ram rw
initrd /boot/initrd.img
EOF
then run lilo
/sbin/lilo -v
then reboot and choose vl install from lilo menu
this will start the installer which should find the ISO on the fat32 partition and let you format the linux partitions as XFS
