I create an MBR like this, where nc/nt/ns are the # cylinders, #
tracks/cyl, # sectors/track on the target disk (see disktab(5)), ASIZE
and ESIZE are the size of BSD partitions 'a' and 'e' (MBR partitions 0
and 1), and IMAGE is the name of the file I write the disk image to:

        _FDISK="$TOOL_FDISK -c $DESTDIR/usr/mdec/mbr"
        _FDISK="$_FDISK -F -t $DISKTAB -T $DISKTYPE -f"
        _FDISK="$_FDISK -b $nc/$nt/$ns"
        $_FDISK -i $IMAGE
        $_FDISK -u -0 -s 169/$ns/$ASIZE $IMAGE
        $_FDISK -u -1 -s 169/$(($ns+$ASIZE))/$ESIZE $IMAGE
        $_FDISK -a -0 $IMAGE

BTW, I create partition 'a' like this:

        $TOOL_MAKEFS -x -F $DESTDIR/metalog.image -N $INSTDIR/etc \
            -o bsize=4096,fsize=512 -m ${ASIZE}b $TGT_IMAGE $INSTDIR || exit 1
        $TOOL_DISKLABEL -F -f $DISKTAB -w $TGT_IMAGE $DISKTYPE || exit 1
        biosboot=$DESTDIR/usr/mdec/bootxx_ffsv1
        CUW_INSTALLBOOT="$TOOL_INSTALLBOOT -o console=${CUW_BOOT_CONSOLE}"
        $CUW_INSTALLBOOT $TGT_IMAGE $biosboot
