How to wipe iBook hard drive if CD player no longer works?

[quickquestions]

Hello. I am looking to sell my old iBook (for parts) but first want to wipe it clean. Unfortunately, part of the reason I want to get rid of it is because the cd player doesn't work anymore. Therefore, I am unable to 'c' boot from the original OS X disk and erase the hard drive. Is there another way to wipe all personal info from my computer, leaving only the operating system?

Thank you.

Start it in Firewire Target mode and erase it from another Mac.
