Strange problem with Floppy Drive

[Dr Lyman Hazelton]

I have an AMD K6 based system with almost everything on ultra-wide, 
ultra-fast SCSI.  The exceptions are video, sound and floppy disk.  
The IDE floppy disk works fine if, for example, I boot from it on 
this machine.  Further, I have removed it and tested it on a Windows 
2K system, where it works just fine.  However, when I boot FreeBSD 
(version 5.1), I get the following messages in dmseg:

fdc0: cannot reserve I/O port range (1 ports)
fdc0: cannot reserve I/O port range (1 ports)
fdc0: cannot reserve I/O port range (6 ports)

and, of course, the floppy isn't available.

Any suggestions about what may be wrong here and how to go about 
making it work?  Floppy drives are inexpensive, and I don't mind 
getting a new one if there's something wrong with the hardware, but I 
don't understand why it works on other systems and why the same 
system can boot from it.  This just seems very bizarre, and I'm 
stumped.
