Special "system_area=/dev/zero" causes 32k of NUL-bytes.
Use this to discard an MBR which eventually was loaded with the ISO image.

@cindex Partition offset, _definiton
@strong{partition_offset=}2kb_block_adr causes a partition table where the
first partition begins at the given block address. This is counted in 2 kB
blocks, not in 512 byte blocks. If the block address is non-zero then it must
be at least 16. A non-zero partition offset causes two susperblocks to be
generated and two sets of directory trees. The image is then mountable from its
absolute start as well as from the partition start.
@*
Preliminary restrictions: Non-zero offset works only with blank output media
and implies -compliance no_emul_toc.

@strong{partition_sec_hd=}number gives the number of sectors per head for
partition offset. 0 chooses a default value.

@strong{partition_hd_cyl=}number gives the number of heads per cylinder for
partition offset. 0 chooses a default value.
