The table is 2*(sectors/track) bytes long. Each table entry is two bytes in
length. The entries specify the ordering of the sectors for each track on the
disc. The first byte of each entry is reserved and should be set to zero. As an
example, a table for seventeen sectors per track with an interleave of two is
shown in table 8.6.
