Verified Boot
18Software
Read Only firmware verifies the integrity of Read/Write (R/W) firmware. R/W firmware verifies the active Linux kernel. During run time,
the kernel verifies each block read from disk.
If a verification step fails and there is no backup option, the machine enters recovery mode.
The Developer Mode switch turns off verified boot (at the Kernel stage) to enable users to run Chromium OS (or other OS). The BIOS is
always verified.
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.

card.
Recovery mode is entered if verified boot fails.
A user can force recovery mode via a key combination during

Verified Boot
18Software
Read Only firmware verifies the integrity of Read/Write (R/W) firmware. R/W firmware verifies the active Linux kernel. During run time,
the kernel verifies each block read from disk.
If a verification step fails and there is no backup option, the machine enters recovery mode.
The Developer Mode switch turns off verified boot (at the Kernel stage) to enable users to run Chromium OS (or other OS). The BIOS is
always verified.
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.
