Thanx. The discussion section was off-line and the knoppix.org info that I found was in German. So, I googled knoppix cheats and found a copy elsewhere.
atapicd did the trick and it's running -- though very slowly on this computer. It's an old PII 350 w/ 96 MB RAM and a 32X CD drive. But it's the only one with enough idle time to experiment with and it's very similar to the computer that I'm considering installing Linux on and using as a file and e-mail server and as a portal to our DSL connection.
