Best way to reformat Powerbook without original install discs?

Hi all,
I just sold my 15" PB and want to reformat it for the new owner. I lost the original install discs, but I have a legit retail version of Tiger just for this machine. Can I do the hold down 'C' thing, or is there something special about the original install discs?
Thanks,
Amin

The install disks include iLife and all the other software that came bundled with the PowerBook. Really you should put all of that on there again as the buyer will expect it.

In my terms of sale, I clearly stated that iLife would not be included. I also explicitly told the buyer this on the telephone.
