I assume that you have double checked that /dev/sda5 is
the partition to which you have copied the CD-ISO content and
that this partition is formatted with an ext3 filesystem.

Try to boot again - after you get the error message-
the initrd stops and drops you into a shell.

Now you could investigate the situation:

first try:

   > mount /dev/sda5 /mnt/media

    - if it fails there is probably a driver missing. I will
      upgrade to kernel 2.6.28 and include more hardware
      support in the next version anyway

if the last step succeeded please try:

   ls /mnt/media

     - if it fails, please tell me the error message

if you could see the files and directories then please
add one more boot option to your grub menu.lst file

  lb_policyfile=XO-LiveCD.pdf

if this works it was my fault not to update the documentation
accordenly

Thank you for your support, feedback is the best way to improve
software.

Greetings

you need to edit /boot/isolinux/isolinux.cfg and to rebuild
the CD or better create a USB pen with two partitions.

yes it you can configure to boot from USB pen (partition 1)
and have persistance on USB pen partition 2.
