Fair enough. Not a problem. I had to check. :->

If you've installed all of the kernel sources you should find it in 
something like /usr/src/sys/i386/isa/ . You're looking for ft.c 
ftreg.h and fd.c.

ft is definately QIC-117 command set friendly. :-) I think most 
floppy tape drives use this command set anyway.

If you're into mucking about with C then here are my ideas:

1) turn on the debug stuff in the ft.c code to see what is happening. 
2) change the probe code so that it thinks it detects a colorado 
   drive every time.
3) see if that is any better. 

If the above works then it's probably just the probe code that needs 
to be changed. Email me back personally if you need assistance.

At least we're trying things. You never know. It might even work. ;->

Talk to you next time, Joel...
