Thanks to those who responded to my requests for help.

We're glad the list could help you. Now perhaps you could help the list.
When you reply with a (SOLVED) item, would you please leave the details that
got things working for you. That way, the rest of us can often learn
something also. For instance, I have an ATAPI DDS4 tape drive in an old
system that I plan to move to FC4. Although the details would probably be
somewhat different for me, your solution could well provide me with
information and hints when I do start that project.
Thanks, Tom
