It's possible that your floppy has indeed bitten the dust. Certainly
you won't be able to use it from FreeBSD until the kernel probes for
it at boot time. You should see both fdc0 and fd0, like this:
happy-idiot-talk:~:% grep fdc /var/run/dmesg.boot
fdc0: <NEC 72065B or clone> at port 0x3f0-0x3f5,0x3f7 irq 6 drq 2 on isa0
fdc0: FIFO enabled, 8 bytes threshold
fd0: <1440-KB 3.5" drive> on fdc0 drive 0
However, to confirm that it has actually blown up, beg, borrow or
steal a bootable floppy from somewhere and see if the box can be
persuaded to boot from it. One of the FreeBSD installer disk images
would be a good choice, or a memtest86 disk from
http://www.memtest86.com/.
If the drive is still working, it suggests that somehow it's got into
an inconsistent state and can't respond to the kernel's probe
attempts. That shouldn't happen --- the kernel should be able to
interface with the hardware and put it into a consistent state however
it was left.
You might find that simply booting from a floppy image resets the
drive and that the next time you reboot into FreeBSD it starts working
again. Otherwise you should try completely powering down your system
--- not just hitting the power switch on the front, but unplug it from
the wall and leave it for at least 10 minutes so that any internal
capacitance can discharge.
Cheers,
Matthew
