Help! I need a bootable Slackware disc. What ISO image am I looking for?

I want to be able to put a CD-Rom into a PC, boot from the disc, run a few commands to set a static IP address, and then use NMAP to scan another IP address to see what ports it has open.

I'm specifically trying to test for the (invalid) port 0.

EDIT: I believe I'm looking to make a "live cd."
