Here is an example of what the partition information will look like once
you have entered the disklabel editor. Disk partition sizes and offsets
are in sector (most likely 512 bytes) units. Make sure these size/offset
pairs are on cylinder boundaries (the number of sector per cylinder is
given in the 'sectors/cylinder' entry, which is not shown here).

Do not change any parameters except the partition layout and the label name.
It's probably also wisest not to touch the '16 partitions:' line, even
in case you have defined less than sixteen partitions.

[Example]
16 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:    50176        0    4.2BSD     1024  8192    16   # (Cyl.    0 - 111)
  b:    64512    50176      swap                        # (Cyl.  112 - 255)
  c:   640192        0   unknown                        # (Cyl.    0 - 1428)
  d:   525504   114688    4.2BSD     1024  8192    16   # (Cyl.  256 - 1428)
[End of example]
