You are probably running into a problem with the partition table, or
lack thereof!  This will require that you run fdisk and create a
partition that is 'owned' by FreeBSD.  The FreeBSD partition code is
sysid 165.

In terms of disk topology, you can probably fake something reasonable by
simply using the formula-

	cylinders = <disk-size-in-blocks> / 2048
	heads     = 32
	sectors   = 64

or is that sect=32, heads=64 (I can't remember but it probably doesn't
matter antway).
