Dell Chromebook 5190 2-in-1 - Disk Partition Map

Disk Partition Map
There are two copies of Chrome OS on disk: an active copy and a backup copy. Each copy consists of a kernel partition and a
root file system. The backup copy is updated automatically in the background. Users only need to reboot. The partition contains
encrypted user data and is also used in the factory for storing test software.
