Administrator password problem

I am trying to reinstall OSX 1.2 on a work computer.  The auto login was turned off and the admin password is not known. There are no other users. When I load the cd it asks for the password before I can install.. Any ideas?

This thread lists several ways to change user passwords in OS X

From which I like this method--
1.  hold down Command-S to boot into single user mode
2. mount -uw /
3. Systemstarter
4. ...wait until the message 'System started' and hit RETURN
5. niutil -list . /users
6. passwd usernamehere --
7. reboot

Also a similar thread on ExpertsExchange
step 6 'usernamehere' will be one of the usernames you saw from step 5 (e.g. 'root', 'administrator', 'jane', etc.)
if i am not mistaken, when you boot from the CD there is a option "Change Administrator Password" or something to that effect in one of the menus. You could try that out as a easy GUI alternative, otherwise the booting into single user mode as described above should work.

When I enter SystemStarter I get the message that SystemStarter is loaded.
Trying plugin /System/Library/CoreServices/SystemStarter/QuartzDisplay.bundle/QuartzDisplay...Loaded (Date and time) SystemStarter: initializing display context.
"waits for a short while " Say: kCGErrorFailure : initCGDisplayState: No display interlock
zsh: bus error systemstarter
Am I doing something wrong.  I have also tried: mount –uw / Systemstarter and recieved a permission denied. Can you help?
The loading the cd answer worked fine (Thanks) but I would like
 to know if the other works too.
Thanks,  Dan
I am not too sure about Systemstarter, but if you look into the link he posted there is another tip for setting the root password and then booting off that. I am pretty sure that works fine too.
