New name for Floppy disk devices?

[Dr. Lyman Hazelton]

OK, so sometimes serial devices that one would expect to have names in 
/dev like sio0 or sio1 are now called cuaa0 or cuaa1 (for reasons 
beyond my understanding).  Now I can see my floppy disk in the dmesg 
output, but there doesn't appear to be an fdc0 in /dev.  Did floppy 
disk devices get renamed, too, or is it hiding somewhere else, or did 
it, for some unknown reason, just vanish?  I'm trying to create a 
floppy disk boot pair, and can't write to a device I can't find.   
Help?
