11. Extended Partitions

• If more than four partitions are required, the fourth table entry points to a Primary Extended Partition (PEP)

  • MBR points to three Primary File Systems plus the PEP

• PEP points to a Secondary File System and a Secondary Extended Partition (SEP)

  • SEP points to additional Secondary File System or Secondary File System/Extended Partition pair

• Extended partitions essentially form a linked list to all of the needed file systems
