PLEASE HELP: Tiger Install on PowerBook 667

I am trying to install Tiger on my Ti PowerBook 667. Currently I am running 10.2.8 on the machine. When I start up the laptop (while holding the C key) with the install dvd 1 in the drive, my screen goes grey and I get a weird Kernel message. Here is a pic of the screen, what can I do???

Any help would be appreciated, thanks!

If you are using 3rd party RAM, pull it out and try again with just the Apple supplied RAM. Also be sure you're firmware is up to date.

System boots just fine in 10.2.8. There is no 3rd Part RAM installed. I only receive this message when I boot with the install disc in...
