I've seen this before, and I think it is a geometry problem. Boot
the system in verbose mode (off the floppy), and go back and see what
the boot probe thinks the geomtery is. (blat the boot partitions first,
if you can).

Then, when you fdisk, make damn sure that the probed geometry is used.
After that, you shouldn't have probelms. If that fixes your problem,
please report it in detail to phk@freebsd.org so we can get a more
permanent fix.
