Allen,
I am sure it is some kind of bug.  I booted my system off of the sdc,  
Thinking I would check the nitros9 sdc
commands again.

Starting out, the floppies still not working......    I issued the sdc 
command to see if i could get it to spit out a help.
Well, I then tried the floppies, and now they work!

Perhaps the guy who (sry, can't remember name) could figure it out, but 
I am satisfied that I can now make it work.

Have a great day!
