I've used "tohd" and "fromhd" to run Knoppix from my hard disk.
I can then eject my CD, and put another one in.

Unfortunately, I don't yet know how to do anything with it.
The disk partition gets mounted on /cdrom, so I don't know how to get at the CD itself.

(I'd like, for example, to be able to grab a copy of the Knoppix on my CD and burn a copy onto a blank CD.)

Am I just missing a step? Is there a better way to get access to my CD while running knoppix?
I'd prefer not to do a full, HD, Knoppix install.
