Yes, the floppy is enabled in the BIOS.  The floppy is the first device in
the boot order.  No the floppy is not "swapped" in the BIOS.  

If the floppy were not the first device in the boot order, it wouldn't load
the bootstrap upon reboot.  I don't do anything other than put the boot
floppy into the drive, then reset the system.  I can boot other operating
systems from this floppy drive.

Is there someway to tell the bootstrap not to probe for the boot device,
but rather explicitly go to this floppy drive?

I experimented with the two floppies, mfsroot, and boot floppy.  It appears
the boot floppy's bootstrap has special code to load the compressed kernel,
along with probing for the boot device.  If I boot the system with the
mfsroot floppy in, I get the FreeBSD boot prompt, and when I tell it to
boot (after switching the floppy in the drive to the boot floppy)
0:fd(0,a)/kernel.gz  the error message I get is: 
invalid format
but it does try to boot the kernel from the floppy.
