Problem getting system to boot of cd or load single user

[talley]

I have a G4 ibook that I'm working on that was previously used as a text to speech device that is now being re-purposed. My problem is I cannot for the life of me get it to boot off a cd, I have tried C and apple-s to reset the admin password, neither worked. I have a osx 10.4 boot disc to use.

My question is whether or not the original provider who setup the system could have supplied a custom firmware for it to prevent it from being modified? And if so, do I have any options?

Thanks a bunch.

its a lingraphica system if that helps, I believe that there is indeed a modified openfirmware on the system, wondering there is a way to reset that.

It sounds like whoever owned the system before you applied an open firmware password. You can clear this out by changing the amount of ram installed and then clearing the PRAM 3 times.
