OK, looks like it installed - the message was that it installed- though now I'm not sure how to get into Knoppix.
In other words, I turn the machine on, and the only options I have are to start the Windows OS's on the first hard drive. The second hard drive with Knoppix on it doesn't show up when I start the machine (which may be normal) and it isn't recognized from My Computer (which may also be normal ).

The short of it is, how do I get into Knoppix now?

Thanks folks!
