How do I edit the "Kernel command line" for Fedora 17 live CD?

I burned a non-rewritable live CD from my Windows box ( using InfraRecorder ) intending to install it on an OLDER PC that I had gotten from work ( with the drives wiped ).

When I start up, I see the expected splash screen, and then the gradually filling circle ( I use fed 15 at work ). but then get a problem similar to that in "Fedora 17 live cd fail" -

An answer that would appear to apply is "I encountered this error and changed the boot command from "live:CDLABEL..." to "live:/dev/sr0". My CD drive is /dev/sr0, so perhaps try changing it to whatever yours is.". BUT I HAVE NO IDEA WHERE THAT IS ( or what to do afterward ) If I can use vi on something from the dracut prompt, I can do that, but I can't tell what to edit ( or what specifically to change )

I assume that after I do that, I can run some command to restart things, but don't know what that might be either.

Here there are some useful notes to customize the kernel line before actually starting a live CD:

Boot options are extensively shown here:

Kernel boot arguments of the liveCD appears if you press TAB on the first screen, the one with the count down appearing before the boot sequence (where you see the Fedora logo) starts.

You can edit in place the boot parameters but they are not persistent so will be used just for that boot.
