>Description:

	fdisk when invoked from a script using the following line will
	not write the bios/mbr geometry.  It appears to do nothing, 
	leaving the default geometry.

	    fdisk -f -i -b ${DLCYL}/${DLHEAD}/${DLSEC} ${disk}

>How-To-Repeat:

    #!/bin/sh
    partition_id=169 
    disk=wd0
    dd if=/dev/zero of=/dev/r${disk}d bs=64k count=10
    fdisk -f -i ${disk}
    eval `fdisk -S $disk`
    echo "Writing the sector-0 partition table"
    fdisk -f -i -b ${DLCYL}/${DLHEAD}/${DLSEC} ${disk}
    echo "Configuring partition-4 of sector-0 partition table"
    fdisk -3 -afu -s ${partition_id}/0/${DLSIZE} ${disk}
    fdisk ${disk}
    # end

 	Thanks to Rex McMaster for sending a script known to work under
	netbsd 1.5 .  Whatever broke, seems to have broken recently.

>Fix:

	Find a windoze box, fdisk there.  (Ok thats a joke!)
