OK. You are going to need to reset the 'root' password (root is the administrator) Once you do that you can edit the yaboot.conf file and allow the machine to boot from CD and everything should be OK. Look at this thread on how to reset the root password:
yaboot.conf should be under /etc
When you get into the machine it will probably be in text mode (no graphical user interface) but you can use a simple editor like 'nano'
You will need to add 'enablecdboot' to that file, it should look similar
Save (press the Control key and x and save the file) Reboot holding down the 'C' key and you should be able to boot from CD.
Edit: I was also going to say that if you do manage to reset the password and get into the system and there is no gui you could check to see if one is installed by typing:
This will make it easier for you if you feel uncomfortable using the command line. You will be able to navigate to the location of yaboot.conf and use a GUI editor.
