                  Welcome to Debian GNU/Linux etch!

This is a Debian installation CDROM, built on 20070407-11:37.
Keep it once you have installed your system, as you can boot from it
to repair the system on your hard disk if that ever becomes necessary.

WARNING: You should completely back up all of your hard disks before
  proceeding. The installation procedure can completely and irreversibly
  erase them! If you haven't made backups yet, remove the rescue CD from
  the drive and press L1-A to get back to the OpenBoot prompt.

by applicable law.
